The complete system from

one source

Whether it is tap water, radia tor

connection or compressed air

applications – the Uponor MLCP

system is the perfect solution. The

comprehensive program permits the

complete installation from the

house connection line to the

consumer. The installation is simple

and economical: The core of the

system, i.e. the Uponor Unipipe

MLC pipe and the relevant fi ttings,

are manufactured in house and

therefore perfectly coordinated.

Through the inherent stability of

the pipe and the low linear expan-

sion, only a few mounting points are

necessary – the practical advantage

for a safe and fast installation. The

Uponor MLCP system is rounded off

by a well thought out Tool program:

from pipe cutting tool over bevel-

ling tool up to pressing tools.

Basis for your professional

installation

Permanently watertight, together

with a long service life, are the most

important requirements that are

demanded today from a reliable and

high-quality installation. Uponor as

a leading manufacturer of plastic

pipes for house construction and

municipal technology fulfi ls these

requirements without reservation

with its Uponor MLCP system. With

this system we offer you the

security that is so impor tant for

your installation.

The Uponor MLCP system

Tested Quality

With the Uponor MLCP system you

install tested and certifi ed quality.

Thus you observe all required

building regulations, including fi re

protection, sound protection and

thermal insulation regulations.

The system technology is also here

particularly long-lived and safe,

certifi ed by numerous tests and

licences.

With our 5 layer composite pipe

we developed a product with

a future, which combines the

benefi ts of both metal and

plastic pipes. Product benefi ts

are obtained that cannot be

surpassed: The inner aluminium

pipe is absolutely safe against

oxygen penetration. It compen-

sates for the snap-back forces

and the linear expansion caused

by temperature changes. The

basis of the system is simple,

safe and fast pipe installation:

simply bend by hand, cut to

length, bevelling, join together,

press – done!

Corrosion resistance

The Uponor Unipipe MLC pipe con-

sists of a long itudinal safety welded

aluminium pipe, to which an inner

and outer layer of high temperature

resistant polyethylene is applied (in

accordance with DIN 16833). All

layers are permanently bounded to-

gether by means of an intermediate

adhesive layer. A special welding

technique guarantees a maximum

of safety. The thickness of the alu-

minium selected for the Uponor

Unipipe MLC pipe is exactly adapt-

ed to the compressive strength re-

quirements as well as the bending

capability.

The Uponor Unipipe MLC pipe has a comparatively low linear expansion due to the plastic fi lm‘s fi rm bond to the aluminium

The best insulation

The Uponor Unipipe MLC pipe for

tap water installation and radiator

connection can also be ordered pre-

insulated. You have an assortment

available in sizes from 16-25 mm

that fulfi ls all insulation require-

ments of DIN 1988-2 and the

German Energy Saving Directive

(EnEV). The pre-insulated pipes

save installation time because the

time intensive insulation of the

mounted pipes and the resulting

gluing of joints are eliminated.

The resilience of the multi-layer

composite pipe is checked regularly

by tensile testing. Along with the

continuous laboratory testing of the

pipe, each Uponor Unipipe MLC

pipe is checked during production

for accuracy of size and water tight-

ness.

Fast, simple, safe: The connection technology for Uponor Unipipe MLC pipes

Extensive program from a

single source

Uponor shows its strength in the

development and manufacturing of

a fi tting concept precisely coordi-

nated to the pipe being used. The

pipe fi tting program with its cou-

plings, elbows, T-pieces and large

number of practical system compo-

nents satisfi es your every need:

Pressed or compression – both

methods can be used and ensure

durable watertight connections.

The fl exibility of the Uponor

Unipipe MLC pipes can often re-

duce the number of elbows needed

for the installation. This substan-

tially lowers material costs as well as

reducing installation time. Further

benefi ts are shorter fi tted length

and an increased installation safety.

Even with complicated applications

you fi nd the right connection in

Uponor‘s extensive fi tting program

– whether press or compression.

Uponor MLC press fi ttings

Connections can be made within

seconds with the patented Uponor

press system. Complicated connec-

tion techniques such as a welding

or soldering are not necessary.

The connection technique produces

permanent watertight press, clamp

and compression connections, as is

confi rmed by the SKZ test reports

and DVGW certifi cates.

Metal MLC press fi tting with

coloured stop rings

The Uponor press fi tting 14-32 mm

is a new generation metal press

fi tting. Because here reliable testing

is standard. The fi tting is manufac-

tured with optimized support sleeve

geometry; a stop ring and press jaw

guide ensures simple, skew free

pressing. O-rings ensure an abso-

lute watertight connection between

the support sleeve and inner pipe

wall. The system is certifi ed by

DVGW.

The installation friendly metal press

fi tting is designed in such a way

that, during the prescribed pressure

test, water leaks from the un-

pressed connections or the fi tting

separates from the pipe. That

means, simply press and a durable

and watertight connection is guar-

anteed.

Coloured stop rings on the practice

proven installation friendly Uponor

press fi ttings are the sign of the

new Uponor fi tting generation. Each

nominal size from 14 to 32 mm has

its own colour – this brings clarity

to the building site, the warehouse

as well as to the wholesaler.

Test reliability is built-in at the factory: The Uponor MLC press fi ttings 14 – 32 mm

1. ApplicationThe press jaw is placed onto the press guide of the press sleeve.

2. PressingDuring the pressing procedure the stop ring breaks into pieces and falls off of the press sleeve.

3. TestingThe missing stop rings reliably mark a success-ful connection. This can be recognized at a distance of many metres.

4. InsulationContinuous pipe insulation such as Tubolit can be easily pushed over the obstacle-free connexion.

If a connection is still not pressed, this is shows up doubly when pressing. The coloured stop rings are still attached. Additionally fi tting is designed in such a way that during the pressure test water leaks out. Now simply press and the connection is permanently tight.

During installation the Uponor Unipipe MLC pipe it is pushed

between the supporting sleeve and stainless steel press sleeve and

a force-closed connection is made with the Uponor composite

fi tting. Pressed into the inner plastic layer of the pipe, the special

profi le of the PPSU insert produces a reliable connection. A high-

temperature and age resistant O-ring fi tted into a groove provides

sealing between the insert part and inner wall of the pipe.

Planning basis for tap water installation using the Uponor MLCP system

Fields of application

The Uponor MLCP system is

applicable for all sanitary facilities,

e.g. for commercial and public

buildings, house construction, series

cleaning plants and barrier-free

construction.

The large selection of Uponor

Unipipe MLC pipes and fi ttings in

the dimensions 14 to 110 mm

permits safe and fast tap water

installation from a one-family house

up to special usage buildings.

The Uponor MLCP system offers a

large selection of special solutions,

whereby all individual requirements

in existing as well as new construc-

tion can be covered. All currently

available sanitary equipment and

fi ttings can be connected to the

system. This is ensured by the

assortment of fi tting and equip-

ment connections. When installing

the pipe systems you must ensure a

perfect isolation of all components

from the structure. For this purpose

Uponor offers the sound protection

set for wall plates.

Certifi cates

According to DVGW worksheet

W 542 a minimum useful life of

50 years must be proven for multi-

layer composite pipes used in tap

water distribution systems. For this

purpose an independent testing

institute runs a series of tests in

order to produce an internal pres-

sure creep rupture diagram. For

Uponor this report was produced by

the South German Plastics Centre in

Wurzburg (SKZ). Along with other

tests, the internal pressure creep

rupture diagram forms the basis for

DVGW issuing a mark of approval

for Uponor with all associated

connectors. Together with the test

institute and DVGW, Uponor works

continuously on the testing of the

pipe system in accordance with all

relevant DVGW worksheets.

DVGW certifi cation permits the use

of the Uponor MLP systems in tap

water installations in accordance

with the requirements of DIN 1988

TRWI (Technical regulations for

drinking-water installations) All

components coming into contact

with tap water are materials and

articles in the sense of the German

Foodstuff and Consumer Goods

Act. The Uponor MLCP system

corresponds to the recommenda-

tions of the German Federal Board

of Health (KTW recommendation),

and through the DVGW mark of

approval is also accordingly

reviewed and recognized.

The brass alloy used for the Uponor

MLC fi ttings corresponds to DIN

50930-6 and fulfi ls the require-

ments of the German tap water

directive (TrinkwV).

For use world-wide, Uponor has

more than 60 international certifi -

cates (e.g. ÖVGW, SVGW, KIWA,

CSTB, etc.).

Measures for inhibiting the

growth of legionella

Conditions must be established that

inhibit an unhealthy concentration

of legionella in hot water tank

systems and their attached warm

water distribution systems.

Legionella is rod-shaped bacteria,

which naturally occur at low con-

centrations in fresh water e.g. lakes,

rivers and occasionally also in tap

water. Approximately 40 forms of

the legionella bacteria are known.

Some legionella forms can cause

infections through the inhalation of

contaminated aerosols (fi ne water

droplets) e.g. while showering or

through moisturizers in air-condi-

tioners. For people with health

problems e.g. weakened immune

system, chronic bronchitis etc. this

can lead to pneumonia (legionella

pneumonia or legionnaire‘s disease)

or to Pontiac fever.

According to DVGW worksheet

W 551 the infection risk is a direct

function of the temperature of the

water from the tap water installa-

tion. The temperature range in

which increased the legionella

growth appears is appropriate

between 30 °C and 45 °C.

Based on the present level of know-

ledge, the workpaper describes the

necessary technical measures for

the reduction of legionella growth

in tap water installations. Additional

measures are described for the

rehabilitation of contaminated tap

water systems.

Circulation systems

Warm water distribution systems in

which warm tap water is constantly

available at the taps must main-

tained permanent hot water circula-

tion. For the operation of circula-

tion systems, the conditions as

stipulated in DVGW worksheets W

551 and W 553 must be maintained

in order to avoided the above

mentioned health risks.

Requirements

The complete warm water distribu-

tion system is to be operated in

such a way that on the one hand

the warm water leaves the tap water

heater with at least 60 °C and

returns to the heater with a tem-

perature loss of no more than 5 K.

On the other hand a suffi cient

warm water volume fl ow must be

present in all circulation lines. The

DVGW worksheet recommends the

operation of a circulation system

with a water temperature of at least

57 °C at the end of each return

line. The required fl ow rates are

calculated in accordance with

DVGW worksheet W 553.

This worksheet contains three

calculation procedures:

A short procedure for small

systems (e.g. one and two family

houses), with which no calcula-

tions must be made.

A simplifi ed procedure for all

system sizes with the goal of

supplying a calculation method

which supplies suffi ciently

accurate results for the draft and

the implementation without

excessive effort.

A differentiated procedure for all

system sizes with the goal of

achieving a better approximation

of the real operational condi-

tions, particularly for large

systems.

The mentioned calculation methods

should be taken from the DVGW

worksheet W 553. The Uponor HSE

calculation software is available for

these calculations.

Uponor „Aquastrom T plus“

Thermostat preset for circulation conduit

Uponor “Aquastrom T plus” is a preset thermostat for

circulation conduit that conforms to DVGW worksheets

W551 and W553. It regulates the circulation water

temperature in the recommended range of 55 °C to

60 °C (max. control range 40 °C to 65 °C; accuracy

+/- 1 °C). The valve automatically supports thermal

disinfection. The volume fl ow rises approximately 6K

above the set temperature and reduces itself, inde-

pendent of the temperature set, starting from approxi-

mately 73 °C on the remaining volume fl ow. The valve

thereby optimally supports the thermal disinfection of

the circulation system. The maximum volume fl ow can

be preset and locked, independent of the temperature

set. The valve is made from red brass and is equipped

with a drain valve with a hose mounting that allows the

circulation branch line to be emptied for maintenance

purposes. Temperature monitoring is possible with

thermometers or temperature sensors. The temperature

setting is protected against change by a seal cover. The

temperature value set can still be read.

Benefi ts

Automatic thermal regulation of the volume fl ow

Supports thermal disinfection

Volume fl ow rises approx. 6 K above the temper-

ature set, thus quickly reaching the disinfection

temperature in the branch line

Restricted above 73 °C, the volume fl ow is again

normalized in order to ensure disinfection of

additional components

High corrosion resistance

Temperature setting can also be read with a seal

cover installed

Later sealing is possible

Temperature monitoring with thermometer or

The Uponor Unipipe MLC pipe is

suitable for use with trace heating.

The inner aluminium pipe ensures

uniform heat distribution around the

pipe, the customary temperature

limitation of 60 °C by the manufac-

turer is to be respected. The fi xing

of the heating band is to be done

according to the manufacturer’s

instructions, whereby the Uponor

Unipipe MLC pipe is to be classifi ed

as a plastic pipe.

You must make sure that the water

can expand correspondingly if

Uponor Unipipe MLC pipes with a

self-regulating heating band are

permitted. If this is not the case,

e.g. as with tank outlets to the

warm water distributor, short lines

to the usage points or with house

connection lines that only bypass

one story, damage of the Uponor of

pipe due to the high increase in

pressure cannot be ruled out.

For these cases suitable safeguards

are to be taken, e.g. the installation

of a suitable safety valve or expan-

sion vessel.

Note:

The pressure increase of the

components due to the use of heat-

ing tape is to be closely watched.

Suitable safety precautions are to

be planned that ensure pressure

equalization. The manufacturer’s

assembly guidelines and installation

notes for the self-regulating

heating band must be observed.

Use of trace heating

Connection to a instantaneous

water heater

Due to their construction, hydrauli-

cally controlled, electrical and gas

fi red fl ow heaters can build up high

temperatures and pressures, both in

normal operation and as a result of

a failure, which can cause damage

to the pipe system. The Uponor

MLCP system may only be directly

connected to electronically control-

led equipment. The manufacturer’s

instructions must be observed when

using electronically controlled

equipment to heat tap water.

Connection to a hot water tank

Generally it must be ensured when

connecting hot water tanks (par-

ticularly with direct fi red hot water

tanks, solar storage tanks and

special constructions) that in

normal operation as well as in the

case of a failure, the operation

limits of the Uponor Unipipe MLC

pipe are not exceeded. This applies

in particular to the maximum warm

water outlet temperature, which is

to be checked at start-up or be

obtained from the manufacturer. In

the case of doubt, suitable safety

precautions are to be taken (e.g.

installation of an industrial water

mixing valve).

Mixer connections

Fitting connection installation must

be torsion-proof (e.g. by fi xing the

press tap elbow on mounting

brackets or mounting plates).

Humidity protection

The humidity protection required in

sanitary facilities is regulated by

DIN 18195-5 “Water-proofi ng

against non-pressing water”. The

following implementations are

limited to humidity protection

within the area of sanitary fi ttings

and wall bushings, e.g. within the

area of dry lining panelling.

Each sanitary facility can be divided

in two “humidity classes”:

Humidity protection in the area

of sanitary fi ttings and wall

penetration

With concealed fi ttings, a seal must

be made to the brick-work or the

opposite dry lining panelling with

a suitable humidity seal. The tiler

integrates these in accordance with

the generally accepted rules of

technology into a surface seal. The

same applies to wall bushings for

equipment connections with surface

mounted fi ttings, e.g. showers and

bath tubs.

Due to moisture build-up (conden-

sites in dry lining panelling, e.g. for

urinal controls, a seal against

moisture penetration must be

applied to building material sur-

faces. All other wall penetrations

within the dry area (e.g. against the

ceramic facings/tiles) can be sealed

with neutrally hardening sanitary

silicone.

As for all tap water installations, a

pressure test in accordance with

DIN 1988-2 is also to be run for the

Uponor MLCP system. Before the

pressure test, all components of the

installation must be freely accessi-

ble and visible in order to be able to

locate unpressed or incorrectly

pressed fi ttings. All open pipes are

to be closed with metal screw plugs,

caps, blanking plates or blind

fl anges. Equipment, pressurized

tanks or tap water heaters are to be

separated from the pipes.

It is recommended to perform the

pressure test with compressed air

or an inert gas if the pipe system is

to remain unfi lled after the test.

At the fi nal inspection the pressure

test and fl ushing must be done

with water in accordance with

DIN 1988-2.

Pressure test with compressed

air or inert gas

The pressure test with compressed

air or inert gas is to be run in

accordance with the generally

accepted rules of technology in two

steps, the leak test and the strength

test. With both tests, before start-

ing the test period, you must wait

for temperature equalisation and

steady-state condition after pres-

sure build-up.

Leak test

A visual inspection of all pipe con-

nections is to be made before the

leak test. The pressure gauge used

for the test must have an accuracy

of 0.1 bar in the display range for

the pressure being measured. The

system is pressurised with a test

pressure of 110 mbar. For a system

volume of up to 100 litres the test

period must be at least 30 minutes.

The required time is extended by a

further 10 minutes for every addi-

tional 100 litres. During the test no

leakage may appear at the connec-

tors.

Strength test

The strength test is to be run fol-

lowing the leak test. Here the pres-

sure is raised to a maximum of 3 bar

(pipe dimension ≤ 63 x 6 mm) or a

maximum of 1 bar (pipe dimensions

≥ 63 x 6 mm). For a system volume

of up to 100 litres the test period

must be at least 30 minutes. The

required time is extended by a fur-

ther 10 minutes for every additional

100 litres.

Pressure testing with water

A visual inspection of all pipe

connections is to be made before

pressure testing with water. The

pressure gauge must be connected

at the lowest point of the installa-

tion being tested. Only measuring

instruments may be used where a

pressure difference of 0.1 bar can

be read. The installation must be

fi lled with fi ltered tap water (pro-

tect against frost!) and vented.

Shut-off valves before and after

boilers and tanks are to be closed

so that the test pressure is kept

away from the rest of the system.

The system is to be pressurized with

the maximum permissible operating

pressure (10 bar) plus 5 bar (in

relation to the lowest point of the

system). Check the maximum

operating pressure with pressure

boosting systems! A suitable time

must elapse to allow for the tem-

perature equalisation between the

ambient temperature and the

temperature of the fi ll water. If

necessary, the test pressure must

be re-established after the waiting

period.

Preliminary test

Re-establish the test pressure two

times within 30 minutes at intervals

of 10 minutes. After a further 30

minutes the test pressure must not

have dropped by more than 0.6 bar.

Main test

The main test is to be run directly

following the preliminary test. The

pressure test is considered to have

been passed successfully if the test

pressure has not dropped by more

than 0.2 bar after a further two

hours.

After completion of the pressure

test all fi ttings are to be checked

for possible leakage. The results of

the pressure test must be recorded

in a report as a record for the

plumber and customer. The forms

at the end of this chapter can be

used for this report.

Pipe line fl ushing

The total system is to be fl ushed

thoroughly as soon as possible after

installation of the pipes and follow-

ing the pressure test. Filtered tap

water (fi lter in accordance with

DIN EN 13443-1) is to be used as

fl ushing liquid. In order to ensure an

unlimited operational reliability,

fl ushing must remove all contami-

nation and installation residue from

the interior surfaces of the pipes

and system components, estab-

lished the quality of the tap water

as well as inhibit corrosion damage

and malfunctions of the fi ttings and

components. In general two fl ush-

ing methods can be used:

Flushing with an air water

mixture in accordance with

DIN 1988-2

This procedure be based on a pul-

sating fl ow of water and air and is

described in detail in the “Tap water

supply systems; materials, compo-

nents, appliances, design and instal-

lation (DVGW code of practice)”

DIN 1988-2 section 11.2. Suitable

fl ushing equipment is to be used.

This fl ushing procedure should be

used if fl ushing with water is not

expected to produce a suffi cient

fl ushing effect.

Flushing with water

If no other fl ushing method is con-

tractually agreed upon or emanded,

the Uponor tap water pipelines are

to be fl ushed using the water

method and local supply pressure.

The procedure for the pipe line

fl ushing is described in the ZVSHK

brochure “Notes on fl ushing meth-

ods for tap water installations in

accordance with TRWI 1988”. This

brochure can be obtained from the

German Central Association of

Plumbing, Heating and Climate-

Control System Engineers (ZVSHK),

Rathausstrasse 6, 53757 St. Augus-

tin. Details and general information

on fl ushing with water can be taken

from the brochure. Under point 4.1

the brochure states:

“The pipes must be fl ushed as soon

as possible after installation. The

tap water used for the fl ushing must

be fi ltered (fi lter in accordance with

DIN EN 13443-1).” In order to pro-

tect sensitive fi ttings (e.g. solenoid

valves, fl ushing valve, thermostats

etc.) and equipment (e.g. tap water

heater) against damage from

fl ushed foreign matter adaptors

should be initially installed in place

of such components. Such compo-

nents should only be installed after

the system has been fl ushed. Built

in fi ne-meshed sieves installed in

front of fi ttings that cannot be

removed or bypassed are to be

cleaned after fl ushing. Aerators,

nozzles, fl ow limiters, shower heads

or shower handsets must be

removed from the remaining

installed fi ttings during fl ushing.

The manufacturers’ installation

instructions are to be followed for

concealed thermostats and other

sensitive fi ttings that cannot be

removed during fl ushing. All main-

tenance fi ttings, fl oor shut-off

valves and pre-shut-off valves (e.g.

angle valves) must be fully opened.

Possibly built-in pressure reducers

must be fully opened and only be

adjusted after fl ushing.

Depending on the size of the sys-

tem and the pipe routing, the

installation can be fl ushed in sec-

tions. In this case the fl ushing direc-

tion and sequence should be from

the main isolation valve in sections

and branches (actual fl ush section)

from the nearest to the furthest

branch. One fl oor after the other is

to be fl ush beginning at the ascend-

ing pipe end.

Within the story and single supply

lines at least as many usage points

specifi ed as a guideline in the

following table for a section being

fl ushed are to be fully opened

one after the other for at least

5 minutes. This is to be repeated

for each story. Within the story the

usage points, beginning with the

usage point furthest away from the

ascending pipe are to be fully

opened. After a fl ushing period of

5 minutes at the fl ushing point last

opened the usage points are closed

one after the other in reverse order.

For the Uponor Unipipe MLC pipe the following guidelines for the minimum number of usage points which are to be

opened in relation to the largest inside diameter of the distribution conduit must be observed:

Pipe friction tables

Dimensioning of the stages (design tables)

The selection of the pipe dimension for a stage can be determined using the following table or from the pressure

drop diagram The required formulae for the dimensioning of the pipes, required minimum fl ow pressure and fl ow

velocity calculation are to be taken from DIN 1988-3.

However, in both cases the maximum fl ow rate and the available pipe friction resistance are to be observed. The

following tables represent the pipe friction resistance and the fl ow rate as a function of the peak fl ow for chilled

water (10 °C).

Radiator connection set

The Uponor radiator connection set

not only facilitates the installation

for you. It also protects the pipe

against damage in the screed as

well as providing for a visually clean

spacing guide.

Radiator connection unit

Pressure testing of the system is

possible before installing the radia-

tors. The preformed Uponor Uni-

pipe MLC pipe in the insulation box

is simply inserted into the wall and

connected with the radiator or the

distribution conduits. The radiator

can simply be mounted at a later

time. The installation of the con-

nection is made in the wall. Your

benefi t: a visually clean connection

and installation of the radiator.

Press connection T-piece

With the press connection T-piece

you can connect the radiator using

coated copper pipes. This ensures a

stable construction for everyday

use. This variation is used if no wall

connection is possible.

The high resilience of Uponor

Unipipe MLCP makes it especially

suitable for heating installations:

Maximal temperature: 95 °C*

Maximum continuous operating

pressure: 10 bar at a continuous

operation temperature of 70 °C,

tested hydrostatic stress per-

formance of 50 years, safety

factor 1.5*

* Please contact the manufacturer if you require additional explanation of the installation parameters.

Fields of application

All heating system components

can be connected using the high-

quality Uponor Unipipe MLC pipes

with an outside diameter of 14-32

mm in coils and 16-110 mm in

straight lenghts together with

suitable system components such

as press and screw fi ttings. The

possibility of supplying over-sized

pipe dimensions of up to OD =

110 mm permits their use as cellar

distribution and house connection

lines in larger heating systems. The

Uponor MLCP system can be used

from the heat generator over the

distribution conduits and house

connection lines up to the connec-

tion to the heat consumer.

Planning basis for radiator connection

Caution:

Uponor Unipipe MLC pipes may not

be directly connected to systems

with operating temperatures ≥

95 °C, such as solar or district

heating systems. It must be ensured

that the operational limits of the

Uponor pipe are not exceeded

under any conditions.

With the following methods you can

realize trouble-free heating water

distribution using the Uponor MLCP

system:

Single-pipe heating system

Double-pipe heating system

Tichelmann system

With a single-pipe heating system

all radiators of a heating circuit are

connected to a closed ring loop.

In this case ring loops are con-

nected directly by a T-piece to the

house connection lines of the heat

generator. If there are several ring

loops, these can be connected to

the Uponor heater distributor. The

distributor is in turn connected to

the house connection line of the

heat generator.

As a rule, the adjustment of single-

pipe heating systems is usually

complex. With a single-pipe heating

system the temperature gradient

between the radiators, i.e. the

decreasing supply temperature from

radiator to radiator, must be

considered when dimensioning the

heating element in the form of an

area surcharge.

Benefi ts are a result of lower

material and assembly costs.

The double-pipe heating system

with its variations for the single

and multi-family dwelling sectors is

particularly suitable for low-tem-

perature heaters. With this installa-

tion variation the radiators are

connected to the supply and

return. All radiators have approxi-

mately the same supply tempera-

ture. A benefi t is the fast and easy

adjustment of the double-pipe

heating system.

Double-pipe heating system

with manifold

With this installation variation the

heating water distribution is con-

nected to the radiators by means

of single inlets from a central mani-

fold. The Uponor manifold is in turn

connected to the house connection

line of the heat generator.

Double-pipe heating system

with tee connection and cross

fi tting

Beginning from the house connec-

tion line, the heating water distri-

bution is made by a common ring

loop. If the ring loop runs directly

by the radiator, the radiator con-

nection can be made with a press

connection tee. The last radiator of

the ring loop is connected by an

Uponor press angle bracket. If the

radiator is connected over a single

inlet to the ring loop, the use of a

cross fi tting is recommended.

Tichelmann system

In the Tichelmann system the pipes

are arranged in such a way that the

sum of the length of supply and

return for each radiator is approxi-

mate equal. That means that the

radiator with the longest supply has

the shortest return. Thus a more

uniform pressure drop in the

individual stages is achieved.

Pressure testing for the radiator installation

Pressure test for radiator

installation in accordance with

DIN 18380

The following procedure describes

the pressure test for the Uponor

MLCP system with screw or press

connections.

The heating engineer/plumber has

to perform a leak test on the heater

pipes after installation and before

closing wall slits, wall and fl oor

breakthroughs as well as, if neces-

sary, before the screed or other

covering is laid.

The heating system is to be fi lled

slowly and completely vented

(protect against frost!). This can be

done quickly and with little effort

with the Uponor pressure test plug.

Water heaters are to be checked

with a pressure of 1.3 x the total

pressure (static pressure) of the

system; however, at least 1 bar

excess pressure must be reached

throughout the system. Only

pressure meters may be used that

permit the accurate reading of a

0.1 bar pressure change. The

pressure meter is to be connected,

if possible, to the lowest point of

the system.

After the test pressure has been

reached a suitable time must elapse

to allow for temperature equalisa-

tion between the ambient tempera-

ture and the temperature of the fi ll

water. If necessary, the test pres-

sure must be re-established after

the waiting period.

The test pressure must be main-

tained for 2 hours and may not

drop by more than 0.2 bar. No

leakages may appear during this

time. As soon as possible after the

cold water pressure test the system

is heated to the highest calculated

heating water temperature to check

whether the system also remains

leak-free at high temperature. After

the system cools down the heating

pipes and connections are to be

checked for leaks.

Example:

Calculating the mass fl ow rate

m (kg/h)

m = QN/(cW x (tVL – tRL))

m = 1977 W/(1.163 Wh/(kg K) x

(70 °C – 50 °C))

m = 85 kg/h

Calculation example

The selection of the respective pipe

dimension depends on the required

mass fl ow rate (volume fl ow) of the

particular stage. Depending upon

the dimension of the pipe’s OD x s,

the fl ow rate v and the pipe friction

resistance R change.

If the pipe selected is too small, the

fl ow rate v and the pipe friction

resistance R rise. This leads to

higher fl ow noises and to higher

current usage of the circulation

pump.

During the design of the pipeline

we recommend that you not to

exceed the following approximate

velocity values:

Radiator connection pipe:

≤ 0.3 m/s

Radiator distribution pipe:

≤ 0.5 m/s

Heating system house connection

and cellar pipes:

≤ 1.0 m/s

The pipe network has to be planned

in such a way that the fl ow rate

decreases uniformly from the boiler

to the furthest radiator. The guide-

lines for the fl ow rate are to be

observed.

The maximum transferable thermal

output QN is to be entered in the

following tables under considera-

tion of the maximum fl ow rate, in

relationship to the type of pipe,

spread ΔT and the pipe dimension

OD x s.

The Uponor planning software

HSE has twice the benefi ts: by its

performance as well as its simple

and fast handling. It is the optimum

tool for planning, drawing and

calculation of sanitary and heating

pipe networks as well as for under-

fl oor heating systems.

HSE does not require an additional

CAD program. Simple drawing

functions are available – horizontal

projections can also be imported to

allow drawing of the installations

onto existing plans.

The result is a genuine time and

cost savings: The complete entry

in tabular form of the horizontal

projections or the building structure

can be done with Uponor HSE

planning software. Exporting is

possible with or without the plan

Planning software Uponor HSE

documents. Planning optimization

with HSE can be run optionally for

operating or investment costs. Any

diagrams required can be automati-

cally generated from the horizontal

projections.

The software package also comes

with the heating load calculation

amendments defi ned in DIN EN

12831 with change A1 to supple-

mentary sheet 1. The entry and

evaluation of data is possible in

both tabular and in graphic form.

Updates for the new planning

software are quick and easy to

access and download from the

internet, 24 hours a day: This allows

you to always work with the latest

software release.

General

The function of the calculation is

the costing of construction works

and the generation of an offer.

Thereby a tender specifi cation is

produced in which the construction

work required is described in detail.

The revision of VOB (General tech-

nical regulations) part C DIN 18381:

2002-12 “VOB assignment and

contract policy for building works

and supplies – part C: General tech-

nical specifi cations for building

works (ATV); – Gas, water and sew-

age plumbing works inside of build-

ings” were published at the end of

February 2003. The important

changes1) include:

A performance specifi cation,

which ensures a correct price

history as well as reduces

extraordinary risks.

Flushing the tap water pipes in

accordance with DIN 1988 and

inspection of gas, water and

drainage pipes were declared as

a special service.

All fi ttings and connection parts

as well as mountings are to be

itemized. The extra payment for

fi ttings and mountings over

63 x 6 mm has been dropped.

For the fi rst time it is established

that the client must supply fi nal

planning documents.

The revision of VOB part C DIN

18380: 2002-12 “Heating systems

and central water heating installa-

tions” was published at the end of

February 2003. The important

changes1) include:

A performance specifi cation,

which ensures a correct price

history as well as reduces

extraordinary risks.

In the future actions to improve

the building air tightness must

be specifi ed.

All fi ttings and connection parts

as well as mountings are to be

itemized. The extra payment for

fi ttings and mountings over

110 x 10 mm has been dropped.

For the fi rst time it is established

that the client must supply fi nal

planning documents.

In the future digitized fi nal plan-

ning documents must be sepa-

rately listed.

Installation times contain the fol-

lowing work:

Preparation of tools and sup-

plementary equipment at the

building site

Reading the plans

Pipe run calibration

Pipe measurement, marking,

cutting to length, bevelling

and cleaning

Pipe installation, including

fastening

Pressing

The following supplementary

services are not covered in the

installation time:

Producing assembly schedules

Setting-up and clearing the

building site

Day wages

Insulation work

Pressure test

Construction control

To prepare a bill of quantities

The supplementary services speci-

fi ed above should be listed sepa-

rately in the tender. The following

specifi ed installation times are

based on the practical experiences

of Uponor users. Furthermore the

calculation methods in Germany

differ greatly from state to state or

within different regions. Due to this

the following compiled installation

times can represent only an approx-

imate costing basis. You can get

more accurate statistics from the

responsible trade associations,

which have access to extensive

data.

Before use all specifi cations are to

be checked for correctness by the

responsible engineer/plumber.

Uponor does not take liability for

the correctness of the specifi cations

or for any possible consequential

damages, which arose or can arise

due to incorrect guidelines, except

for gross negligence or if deliber-

ately wrong data were supplied by

Uponor or their agents.

Installation times include the work

of two fi tters and are indicated in

group minutes.

The main goal of fi re protection is

to hinder fi res. If a fi re occurs, then

the second goal of fi re protection is

to minimize damage.

In the context of building legisla-

tion the State establishes the

preconditions in order to ensure

public safety and prevent danger

from destructive fi res.

The model building code (MBO) is

the basis for all building regula-

tions, including fi re protection

measures. The building codes of

the individual German States are

oriented on this model building

code.

According to MOB 2002 section 14

“Fire protection” (wording and

contents also apply in the individual

German States) pipes that pass

through fi rewalls and stairwells, as

well as walls and ceilings that must

meet fi re resistance grading, may

only be installed if spreading of fi re

or smoke is not a risk or if provi-

sions have been taken against such

possibilities.

For example, when installing Uponor

Unipipe MLC pipes (building mate-

rial class B2 in accordance with

DIN 4102) with an outside diameter

OD ≤ 32 mm spreading of fi re and

smoke is not a risk if the area

between pipe and the remaining

cross-section of the opening is com-

pletely fi lled in with non-combusti-

ble, shape-retaining building materi-

al (closing the cut-outs with mortar

and concrete).

If mineral fi bres are used, they must

have a melting point of more than

1000 °C. In residential buildings the

following basic fi re protection prin-

ciples apply:

Along with the fi re protection

requirements, sound and ther-

mal protection requirements as

well as the thermal expansion/

contraction of pipe systems

must be considered when install-

ing pipes through openings in

walls or ceilings.

Fires and smoke may not

spread into other ventilation

zones within the required fi re

resistance grading (e.g. F 90 =

90 minutes).

All building materials must fulfi l

the building material class B2 =

normal infl ammable.

The high requirements of a fi re

prevention concept that guarantees

health and life can only be realized

with the cooperation of all parties

taking part in the building project

and with a tender and a construc-

tion supervision that is matched to

the project.

Uponor offers comprehensive fi re

prevention solutions for the com-

posite pipe system.

In addition to the requirements of

DIN 4109 an increased sound

insulation can be contractually

agreed upon in accordance with

VDI 4100. This contains similar

sound insulation levels as in DIN

4109 – however with other sub-

sections. In this VDI guideline are

also useful tips for practical sound

insulation planning. Apart from

their function as limits for construc-

tion acoustics, the sound insulation

levels specifi ed above are also of

importance as acoustic quality

characteristics for sanitary products.

A product that meets the sound

insulation levels of SSt II or SSt III

ensures a high measure of noise

reduction and an additional safety

margin for use in the construction

of living and sleeping areas as well

as for instruction and work areas.

The VDI 4100 specifi cations are as

follows:

Sound insulation level I is no

longer state of the art and is

therefore irrelevant

Sound insulation level II

corresponds to the minimum

DIN 4109 requirement of

LIn < 30 dB (A)

With LIn < 25 dB (A) sound

insulation level III ensures an

increased acoustic comfort

However, if VDI 4100 should be

agreed upon in the construction of

double and terraced houses, then

the basic values must all be reduced

by 5 dB (A). If VDI 4100 is contrac-

tually specifi ed, sound insulation

requirements of maximum 30 dB

(A) within personal living areas

must be maintained! If waste water

noises are regarded separately, then

the basic values must be reduced by

5 dB (A). This means that all

installations within personal living

areas must be accurately coordi-

nated with one another and that all

doors must also accommodate

these conditions. The specifi cations

represented here refer to common

rooms in the sense of state building

codes, which makes the specifi ca-

tions more comprehensive than the

areas needing protection pursuant

to DIN 4109.

Structure-borne sound transmission

can be effectively prevented in tap

and waste water systems by the

following measures:

Covering of the Uponor

Unipipe MLC pipes with soft

elastic insulating materials

when installing pipes through

openings in walls or ceilings,

e.g. the normal thermal insula-

tion with/without fi re protec-

tion

Suffi cient dimensioning of the

Building insulation helps to mini-

mize the energy consumption and

lower the accompanying waste gas

quantity as well as the fuel and

power costs. In particular, high

potentials savings can be realized in

building equipment for energy

production and distribution.

The German Energy Saving Direc-

tive (EnEV) demands the limitation

of the heat emission of heat

distribution and warm water pipes.

Insulation requirements

pursuant to EnEV

The insulation regulations in the

German Energy Savings Act (EnEV)

section 12 are to be observed with

new construction and moderniza-

tion of heat distribution and warm

water pipes as well as fi ttings in

buildings.

Heating pipes and their fi ttings are

to be insulated pursuant to lines 1

to 7, warm water pipes and

fi ttings pursuant to lines 1 to 5

from table 1, appendix 5, of the

EnEV. Lines 1-4 represent 100 %,

lines 5-6 50% minimum insulation

requirements.

which were installed after this regulation went into force,

in components between heated areas of different users

7 Pipes pursuant to line 6 in fl oor construction 6 mm

No demands are made for the

minimum thickness of the insulating

layer for central heating pipes

pursuant to lines 1 to 4 when they

are located in heated areas or in a

structural member between heated

areas of one user and their heat

emission can be affected by

exposed isolation barriers. This also

applies to warm water pipes in

dwellings where the pipes have an

inside diameter up to 22 mm, which

are not used in the circulation fl ow

or with electrical companion

heating.

Note:

Under the structural members

described in line 6 are understood,

for example, ductwork or a wall

between two heated areas.

With the use of insulating materials

with a heat conductivity other than

λ = 0.035 w (m x K) the insulating

layer thicknesses are to be recalcu-

lated. The conversion is to be

done using computing methods

and nominal values provided by

the generally accepted rules of

technology.

Cold tap water systems are to be

protected against an inadmissible

temperature rise and, if necessary,

against condensation. Cold tap

water pipes are to be placed at a

suffi cient distance from heat

sources. If this is not possible, then

the pipes are to be insulated in such

a way that the quality of the tap

water is not impaired by a tempera-

ture rise.

With insuffi ciently insulated cold

water pipes condensation can form

Insulation cannot offer suffi cient

protection from freezing during

frost endangered areas. They must

be emptied or be otherwise pro-

During outages insulation cannot

offer suffi cient protection from

Caution:

If necessary, valid sound insulation

requirements are to be observed.

Therefore from a technical and

economic point of view it is nor-

mally advisable to use, also in this

Equipotential bonding

DIN IEC 60364 ff. requires equipo-

tential bonding between all types

of protective conductors and the

“conductive” water, waste water

and heating pipes. Since an Uponor

Unipipe MLC pipe is a non-con-

ductive pipe it cannot be used for

equipotential bonding and is not to

be grounded.

Equipotential bonding is affected

according to the VDE guideline

from the parts that are to be

earthed directly to the equipotential

bus bar at the point provided in the

plan. The installer or construction

supervisor has to point out to the

client or their agent that a certifi ed

electrician must check whether or

not the Uponor installation impairs

the existing electrical protection

and grounding measures (VOB part

C, General technical specifi cations

for building works ATV).

Mixed installations

For tap water installations with two

or more metal pipe systems, as seen

from the fl ow direction, fi rst the

base metal and then the high-grade

material must be used, i.e. fi rst the

galvanized steel pipe then the

copper pipe.

The Uponor MLCP system can be

combined with metal and plastic

pipe systems. As opposed to mixed

installations using different metals,

with the Uponor system it is not

necessary to adhere to a tap water

fl ow direction.

Repair or renovation work

In the past different variations of

the Uponor Unipipe MLC pipe were

delivered.

Red Unipipe F composite pipe

(PE-MD/AL/PE-MD) for under-

fl oor heating installation

Brown Unipipe S composite pipe

(PE-X/AL/PE-X) for tap water

installation

White Unipipe H composite pipe

(PE-X/AL/PE-X) for heating

installation

Since the beginning of 1997 the

white Uponor Unipipe MLC pipe

(PE-RT/AL/PE-RT) has been

delivered for all applications (tap

water, heating and radiant heating

installation).

If older Uponor Unipipe MLC pipes

are to be extended or repaired, the

Uponor MLC press repair coupling

offers the possibility of changing to

the current Uponor Unipipe MLC

pipe. The repair coupling is avail-

able in the dimensions 25, 32 and

40. The inner insert part extended

on one side of the coupling also

simplifi es joining of the pipe ends

to lack of space.

Moreover with the smaller dimen-

sions up to 32 mm the transition of

existing to new installations is also

possible using the composite press

couplings or up to dimension 25

with screw connections in combina-

tion with double nipples.

Standard fi ttings with a stainless

steel press sleeve can be used with

pipe fi ttings starting from dimen-

sion 50 mm.

Threaded connection handling instructions

The thread sealants must have been

tested and approved for the respec-

tive application. The sealants must

be used according to their manu-

facturer‘s instructions. Uponor MLC

press fi ttings may only be coupled

with standard screw threads (DIN

EN 10226).

The threaded connection must be

made before pressing so that no

stress is placed on the press fi tting

connection. The threaded connec-

tions must be made properly in

accordance with the generally

accepted rules of technology. No

undo force may be used when

working with brass components.

Excessive thread sealant (e.g.

excessive hemp packing) at the

threaded connections must be

avoided.

The following points must be

observed when making threaded

connections:

Excessive tightening of the

threaded connection can result

in damage to the material;

suitable tools must be used.

The installation tools may not be

lengthened to increase the force

when tightening a connection

(e.g. by attaching pipes),

All the materials and auxiliary

materials used (e.g. sealants,

installation material and clean-

ers) must be free of substances

that can cause stress corrosion

cracking (e.g. compounds

containing ammonia or chloride).

Caution!

For tap water installations, sealants

must be authorized and certifi ed by

the DVGW (DVGW seal).

Outer corrosion protec-tion of Uponor fi ttings

Because of the external corrosion

protection there are no restrictions

for mixed installation with other

installation systems. The generally

accepted rules of technology are to

be complied with.

In view of the surface corrosion

protection, Uponor MLC fi ttings

can be installed directly in concrete,

screed or under plaster.

However, there are some circum-

stances where protection from

metallic connections or metallic

components that come into direct

contact with building materials

is required, these are the combina-

tion of:

permanent or long-lasting

moisture penetration and

a pH value greater than 12.5.

In this situation we recommend a

suitable covering for the Uponor

MLC fi ttings such as insulating tape

or shrink sleeve. Independent of the

corrosion protection of the mould-

ings, all legal requirements and

relevant standards for the respec-

tive application, particularly from

the stand-point of thermal insula-

tion and sound decoupling, must be

adhered to.

Before applying the insulation the

prescribed pressure test is to be

run.

The thermal length variations, that

result due to changing tempera-

tures, must be considered when

designing pipe routes. Temperature

difference Δt and the pipe length L

play a decisive role in the length

variation.

For all installation variations the

heat expansion of Uponor Unipipe

MLC pipes must be considered in

order to avoid excessive stress in

When planning and installing cellar

distribution and house connection

lines using the Uponor MLCP

system, along with the structural

requirements, thermally caused

linear expansions must be consid-

ered.

Uponor Unipipe MLC pipes may not

be installed rigidly between two

fi xed points. You must always

compensate for the length variation

of the pipes.

Open laid Uponor Unipipe MLC

pipes that are fully exposed to

thermal expansion must be pro-

vided with suitable compensation

for expansion and contraction. For

the pipe material and damage to the

connections, in particular by free

laid pipes such as radiator connect-

ing pipes out of the fl oor or from

the baseboard as well as with cellar

distribution and house connection

lines. For pipes that are laid in the

wall under plaster or in the screed,

the heat expansion is compensated

for by the insulation in the area of

direction change.

The following equation is used to

calculate the length variation:

Δl = α × L × Δt

Here:

Δl: Heat expansion (mm)

Type and distance between the

pipe fastenings is dependent on

pressure, temperature and medium.

The dimensioning of the pipe

supports is to be determined from

the total mass (pipe weight +

medium weight + insulation weight)

in accordance with the generally

accepted rules of technology. It is

recommended to set the pipe

supports, if possible, in the proxim-

ity of the fi ttings and connectors.

Pipe installation onto the raw fl oor

When installing pipes on a concrete

fl oor the generally accepted rules of

technology are to be observed. The

sound insulation is to be installed in

accordance with DIN 4109 “Sound

protection in above ground construc-

tion”. The insulation regulations

pursuant to the German Energy

Saving Directive EnEV and in accord-

ance with the Codes of practice

for tap water installations (TRWI)

DIN 1988-2 are to be observed.

Furthermore, the mobility of pipes

during thermal expansion is to be

taken into consideration (see section

“Thermal length variation”).

If screeds are applied on insulating

layers (fl oating screed), DIN 18560-2

“Floor screeds in building construc-

tion” is to be particularly followed”.

In DIN 18560-2: 2004-04 the

following additional declarations are

made (point 4.1 load-bearing

substrate):

“In order to accept the fl oating

screed the load-bearing sub-

strate must be suffi ciently dry

and have an even surface. The

smoothness and tolerance must

correspond to DIN 18202. It

may not contain any peaks,

pipes or anything similar that

can lead to sound bridges or

fl uctuations in the screed

thickness.

Furthermore, for prefabricated

heating fl oor screeds the

special requirements of the

manufacturer as to the smooth-

ness of the load-bearing

substrate are to be observed.

If pipes are installed onto the

load-bearing substrate they

must be fi xed. A smooth

surface is to be created for the

installation of the insulating

layer – at least the sound

insulation. The required con-

struction height must be

planned for.

When installed, the levelling

layer must exhibit a closed

form. Fill may be used, if its

serviceability is proven. Insulat-

ing materials may be used as a

levelling layer.

Sealing against ground mois-

ture and non-accumulating

seepage water are to be deter-

mined by the building planner

and be prepared before instal-

lation of the screed (see DIN

18195-4 and DIN 18195-5)”.

The routing of the Uponor Unipipe

MLC pipes and other plumbing on

concrete fl oors is to be done non-

intersecting, straight and as axially

parallel and parallel to the walls as

possible. The preparation of a plan

before the installation of the pipe

tracks and other plumbing makes

the installation easier.

When installing Uponor Unipipe

MLC pipes on concrete fl oors a

fi xing distance of 80 cm is recom-

mended. The pipe is to be fi xed

within a distance of 30 cm in front

and behind each bend. Pipe cross-

ings are to be fi xed. The fi xing can

be done using a synthetic plugged

hook for single or double pipe

fi xing.

When using a perforated tape for

fastening, you must make sure that

the Uponor Unipipe MLCP with/

without protective tube or insula-

tion can freely move. Noise can be

caused by the thermal expansion of

the pipe if it is fi rmly fi xed.

If the Uponor MLC P system is

installed directly in the screed, the

pipe fi ttings must have suitable

protected against corrosion.

In order to prevent damage to the

screed and fl oor covering, joints

(expansion joints) are to be placed

in the insulating layer and in the

screed over construction joints.

Uponor Unipipe MLC pipes, which

cross construction joints, must be

sheathed in the joint area at least

with a longitudinally slit Uponor

joint protection tube (20 cm each

side of the expansion joint).

Pipe routing

Pipes and other plumbing in the

fl oor construction are to be planned

without crossings. The routing of

the pipes on concrete fl oors is to be

Distance from wall to pipe/pipe routes including insulation and screed in rooms, apart from corridors

Distance from wall to pipe/pipe routes including insulation and screed in corridors

done as non-intersecting, straight

and as axially parallel and parallel to

the walls as possible.

The following route dimensions for

pipes and other plumbing should be

maintained:

Field of application Width or spacing dimension

Route width of parallel running pipes including pipe insulation ≤ 300 mm

Width of the footing beside a track

(for the narrowest possible pipe-laying) ≥ 200 mm

Distances from wall to pipe/pipe route including insulation

as footing for the screed in rooms, apart from corridors ≥ 500 mm

Distances from wall to pipe/pipe route including insulation

as footing for the screed in corridors ≥ 200 mm

Mastic asphalt is brought into the

room at a temperature of up to

260 °C. Therefore the Uponor

Unipipe MLC pipe and all other

temperature sensitive plastic

components must be protected.

The Uponor system edging strips

can not be used with mastic

asphalt. For this application there

are special bitumen suited mineral

fi bre edging strips, which are to be

procured by the customer.

The Uponor MLCP system can be

used without problems with mastic

asphalt by observing following

precautions.

The un-insulated Uponor Unipipe

MLC pipe must at least be placed in

a protective tube. The use of pre-

insulated Uponor Unipipe MLC pipe

is recommended in order to fulfi l

the requirements of DIN 1988 and

the German Energy Saving Directive

(EnEV).

The Uponor MLCP system is to be

fi lled with cold water and pressu-

rized in order to be able to locate

any possible damage caused by the

laying of the mastic asphalt.

Caution:

Cold water must constantly circu-

late through the pipe in order to be

able to fi nd a any damage caused

by the pouring of the mastic

asphalt.

The installation of mastic asphalt

screed over Uponor Unipipe MLC

pipes can be carried out by observ-

ing the following fl oor construction

(from bottom to top):

Install the Uponor Unipipe MLC

pipe in a protective tube or pre-

insulated Uponor Unipipe MLC

pipe on top of the concrete fl oor

Perlite fi ll as levelling layer to

the upper edge of the protective

tube or pipe insulation

Mineral fi bre mat at least 20 mm

thick (mastic asphalt suited)

WLG 040

Mastic asphalt, pouring tem-

perature approx. 260 °C

System components (pipes and

fi ttings) that can come into contact

with mastic asphalt (e.g. when

installed under a radiator), are to be

sheathed with 50% insulation (at

least 20 mm thick) that is rated as

fi re protection classifi cation A1

(non-combustible) pursuant to DIN

4102 (e.g. with mineral fi bre

insulation sheath RS 835/Conlit

150 P/U). The non-combustible

insulation must fully enclose the

Uponor Unipipe MLC pipe and the

Uponor MLC fi ttings. The joints of

the insulation sheaths and the

transition points of the heat resist-

ant thermal or sound insulation

(mastic asphalt suited) to the non-

combustible pipe insulation are to

be taped with a temperature-

resistant adhesive tape (e.g. Alu-

minium adhesive tape). The insula-

tion sheaths around the pipe can

also be alternatively fi xed with

binding wire.

These measures protect the Uponor

MLC pipe system against radiant

heat and against direct contact with

the mastic asphalt. Pipe parts

extending from the fl oor must be

protected against direct contact

with the mastic asphalt and/or the

radiant heat.

After hardening and cooling of the

mastic asphalt the visible mineral

fi bres in the area of the Uponor

Unipipe MLC pipe or the radiator

connection are to be removed. The

use of a fl oor rosette is recom-

mended for a clean fi nish.

Caution:

The Uponor MLCP system must not

come into contact with the mastic

asphalt. The precautionary meas-

ures described are to ensure that

the maximum temperature on the

pipe surface does not exceed 95 °C!

DIN 18560 “Floor screeds in

building construction”, the specifi -

cations of the mastic asphalt

manufacturer, the diligence and

care of the mastic asphalt supplier,

DIN 4109 “Sound protection in

above ground construction” as well

as the generally accepted rules of

technology apply.

Transport, storage and installation conditions

General

The Uponor MLCP system is con -

ceived in such a way that when

installed as directed a maximum of

system security is achieved. All

system components are to be

transported, stored and installed in

such a way that a perfect function-

ing of the installation is ensured.

The system components should be

stored together grouped as to their

functions in order to avoid confus-

ing similar components with each

other. In addition to the following

notes, the directions in the respec-

tive fi tting instructions of the

individual system components and

tools are to be observed.

Operating temperatures

The permissible operating tempera-

ture for the Uponor MLCP system

(pipes and fi tting) is between

-10 °C and +40 °C. The permissible

temperature ranges for the pressing

tools are to be taken from the

respective operating instructions.

Uponor Unipipe MLC pipe

The Uponor Unipipe MLC pipes are

to be protected against mechanical

damage, contamination and direct

sunlight (UV radiation) during

transport, while stored and when

being installed. Therefore, if

possible, the pipes should be kept

in the original packaging until

installed. This also applies to

unused components that are

intended for later use. The pipe

ends are to be plugged until used in

order to prevent dirt entering the

pipes. Damaged, buckled or dis-

torted pipes may not be used. Pipe

cartons with coils can be stacked up

to a maximum height of 2 m. The

pipe in straight length is to be

transported and stored in such a

way that it cannot bend. The

relevant Uponor storage regulations

are to be observed.

Uponor Fittings

Uponor MLC fi ttings may not be

thrown or otherwise inappropriately

handled. In order to avoid damage

and contamination, the fi ttings

should be kept in the original

packaging until installed. Damaged

fi ttings or fi ttings with damaged

O-rings must not be installed.
