LT: Units for low outside temp. (-45°C)AX_AD_AW_AT Units with condensing pressurecontrol by modulating fan speed on the outdoorunit.

REFRIGERANT CIRCUITAll models have a single refrigerant circuit, and in some cases twocircuits. Each refrigerant circuit includes the compressor and a pressure-balanced thermostatic valve (or electronic valve) to ensure stablesuperheat temperatures. A liquid indicator is fitted before thethermostatic valve to display the gas charge.A filter-drier is installed on the liquid line to keep the circuit cleanand free of dirt. The refrigerant circuit is also fitted with high andlow pressure switches.The low pressure switch has automatic reset, while for safety rea-sons the high pressure switch has manual reset.The compressor pumps the hot refrigerant gas into the con-denser. The liquid refrigerant then flows to a liquid receiver (fittedwith safety valve) installed on the indoor unit, to ensure a con-stant flow of refrigerant to the thermostatic valve and subse-quently the evaporator. Here the liquid refrigerant absorbs theheat from the environment and changes state, becoming a gas,then returning to the compressor: from this point onwards thecycle repeats itself.

AIR-COOLED DIRECT EXPANSION UNIT - VERSIONAXThe AX series units use air as the cooling fluid, and are thereforecombined with an outdoor air-cooled condenser (supplied sepa-rately). The MODULATING version features speed control forthe fans on the condenser, so as to maintain correct refrigerantcondensing pressure. The AX units are supplied with valves forclosing and isolating the refrigerant circuit and to assist serviceoperations. A second non-return valve, to be fitted by theinstaller at the condenser outlet on the liquid line, is recommend-ed during operation in winter, to prevent migration of the refrig-erant charge from the liquid receiver to the outdoor condenser,with consequent low pressure alarms.The AX units are supplied as standard with EC radial fans in thestandard version.

Air-cooled condenser, outdoor installationThe indoor unit can be connected to different types of outdoorcondensers, standard or low noise versions, with special treat-ments on the coils.For the corresponding information refer to the manual on out-door air-cooled condensers.Note 1: the outdoor units and condensers are supplied separatelyNote 2: the indoor unit is delivered charged with nitrogen at nearatmospheric pressure. The outdoor condenser, on the other hand,is supplied pressurised with dry air (around 3 bar.)Note 3: the customer is considered responsible for making thecorrect connections between the indoor and outdoor unit, asclearly indicated in the Installation manual, and for ensuring the gasand oil charges, where necessary.

WATER-COOLED DIRECT EXPANSION UNIT - VER-SION AWThe AW series units use water as the cooling fluid, therefore eachrefrigerant circuit is combined with a plate heat exchangerinstalled on the unit, suitably sized to ensure minimum water sidepressure drop and consequently reduce the power consumptionof the water pump.Remember that the units are supplied without the system circu-lating pump.The AW units are supplied as standard with EC radial fans in thestandard version.

Water-cooled condenserThe units are fitted with an internal braze welded stainless steelplate heat exchanger.The units for applications with well water are supplied with apressure control valve to manage the condensing pressure.This circuit works with primary water or with a closed circuitconnected to an outdoor dry cooler or cooling tower. For “closed” circuits, it’s recommended to use water mixed withantifreeze to prevent ice from forming in winter and consequentlydamaging the system: see the installation manual for the calcula-tion of the percentage of antifreeze to use.The dry coolers are supplied as an optional accessory, while theantifreeze and fluid circulating pump are generally supplied by oth-er manufacturers. For “open” circuits mechanical filters must be used to trap impu-rities and prevent blockage of the braze-welded plate heatexchanger. To reduce energy consumption (pump), it’s suggested to use avalve to close the circuit when the indoor unit is off.

Note 1: the AW water-cooled indoor units come with the refrig-erant circuit completely charged and factory-tested before deliv-ery.


AX - air cooled AW - water cooled


FREE COOLING UNITS – VERSION AFThe AF series units, in favourable outside conditions, can use thecooling water to maintain the set environmental conditions with-out the need for mechanical cooling using the compressor, or toreduce the cooling load.The AF series units use water as the cooling fluid, therefore eachrefrigerant circuit is combined with a plate heat exchangerinstalled on the unit, suitably sized to ensure minimum water sidepressure drop and consequently reduce power consumption ofthe water pump.The AF units are supplied as standard with EC radial fans in thestandard version.

Water-cooled condenserEach unit is fitted with one (single-circuit units) or two (two-cir-cuit units) braze welded stainless steel plate condensers. Each refrigerant circuit features an automatic bypass valve to con-trol minimum condensing pressure during operation in FC mode.The units generally work in closed circuits, with outdoor drycoolers, cooled by the outside air.To avoid ice formation, it’s recommended to always use a glycolmixture as the fluid inside the closed circuit, in the percentagesdescribed in this manual based on the average minimum tempera-ture reached in the installation site in winter.The cooling fluid must be circulated using pumps (not supplied asstandard). Dry coolers in the correct size are available as options.

Water circuitThe unit is fitted with a modulating 3-way valve to control theflow of cooling fluid to the indoor heat exchanger for free cool-ing. The opening and closing signal is generated and managed com-pletely by the electronic controller on the air-conditioner so as tomaintain the desired conditions and ensure maximum energy sav-ings.

DUAL FLUID UNITS – VERSION AD (air-cooled) & AT(water-cooled)The AD and AT series units feature two different cooling systems,which cannot be active at the same time.One primary chilled water system (CW) provided by a chillerinstalled on site, and a secondary direct expansion system (DX),which also acts as backup. The activation set points of these two circuits can be seen in theuser terminal manual.The unit AT and AD are supplied as standard with EC radial fans inthe standard version.

Version AD (air-cooled)The AD series units use air as the cooling fluid, and are thereforecombined with an outdoor air-cooled condenser (supplied sepa-rately). The MODULATING version features condenser fan speed control,so as to maintain correct refrigerant condensing pressure. The AD units are supplied with valves for closing and isolating therefrigerant circuit and to assist service operations. A second non-return valve, to be fitted by the installer at the con-denser outlet on the liquid line, is recommended during operationin winter, to prevent migration of the refrigerant charge from theliquid receiver to the outdoor condenser, with consequent lowpressure alarms.

Outdoor air-cooled condenserThe indoor unit can be connected to different types of outdoorcondensers, standard or low noise versions, with special treatmentson the coils.For the corresponding information refer to the manual on outdoorair-cooled condensers.Note 1: unit and outdoor condensers supplied separatelyNote 2: the indoor unit is delivered charged with nitrogen at near-atmospheric pressure. The outdoor condenser, on the other hand,is supplied pressurised with dry air (around 3 bars)Note 3: the customer is responsible for properly making the con-nections between the indoor and outdoor unit, as clearly describedin this manual, and for ensuring the required gas and oil charge,where necessary.

Water circuitThe unit is fitted with a modulating 3-way valve to control the flowof cooling fluid to the indoor heat exchanger and maintain thedesired conditions.

AF - water cooled AD - air cooled


Version AT (water-cooled)The AT series units use water as the cooling fluid, therefore eachrefrigerant circuit is combined with a plate heat exchangerinstalled on the unit, suitably sized to ensure minimum water sidepressure drop and consequently reduce the power consumptionof the water pump.Remember that the units are supplied without the system circu-lating pump.

Water-cooled condenserEach unit is fitted with one (single-circuit units) or two (two-cir-cuit units) braze welded stainless steel plate condensers. The units for applications with well water are supplied with apressure control valve for managing the condensing pressure.The units generally work in closed circuits, with outdoor drycoolers, cooled by the outside air.To avoid ice formation, it’s recommended to always use a glycolmixture as the fluid inside the closed circuit, in the percentagesdescribed in this manual according to the average minimum tem-perature reached in the installation site in winter.The cooling fluid must be circulated using pumps (not supplied asstandard).

ACCESSING THE MAIN COMPONENTS


The air-conditioner is accessible from all sides by removing thevarious panels.The front and/or side panels are opened in 2 different ways:

FRONT PANELSAll the front panels are hinged and fitted with locking latches andseal. All the front panels are opened and closed using a tool (typically ascrewdriver) to open and close the latches. Once the latches have been opened, the front panels can beswung open and then removed vertically to simplify the serviceoperations on the air-conditioner, especially where there is littlespace available.Opening the front panels provides access to all the componentsin the air-conditioner involved in routine maintenance.The number of front panels depends on the capacity of the air-conditioner.

SIDE PANELSAll the side panels are accessible and removable. Nonetheless, these do not need to be removed for routine main-tenance operations. This means that, if necessary, a series of unitscan be installed next to each other.The side panels are fastened by screws. These are accessible directly on the side panel by removing theblack plastic caps.

BACK PANELSFastened by normal self-tapping screws, these are not accessibleas when installed the back of the unit is against the wall.

INSIDE PANELSThe compartment that contains the fans and the heaters is pro-tected and insulated by a metal plate.This is for safety reasons, so as to not have to shut the unit downduring normal maintenance operations.

WARNING: before restarting the air-conditioner, alwayscheck that all the panels have been correctly replaced.

TRANSPORT AND HANDLING


Move the air-conditioner, which must not be reclined or tippedover, nor exposed to the elements, as near as possible to the siteof installation before removing the packaging and the pallet.

The units can be lifted:- using a forklift, sliding the forks through the openings in the pal-

let;

- using fabric slings underneath the unit, making sure that whenthe slings are in tension these do not apply pressure on the topedges.

The air-conditioner must be stored indoors, preferably in its ownpackaging, and protected against excessive humidity (<85% RH)and temperature (> -20°C , < 50°C).

The air-conditioner can rest directly on the floor, perfectly level,with a maximum difference in height of 5 mm between the endsof the base: incorrect levelling may cause the condensate to leakfrom the collection pan.

WARNING: the air-conditioner must be installed indoorsand in non-aggressive environments. Apply an elastic gasketaround the perimeter of the base to prevent the transmis-sion of noise and vibrations.

SUPPORT FRAME (optional accessory)A support frame is recommended:- to allow the air-conditioner to be installed before assembling

the raised floor;- to totally dampen any mechanical vibrations;- to assist the laying of pipes and cables.

The support frame is available as an accessory and is adjustable inheight, indicated in the figure by the distance X, between 200 and600 mm. To prevent the transmission of noise and vibrations, anelastic gasket, at least 5 mm thick, should be inserted between thepanels of the raised floor and the frame, which must also be insu-lated from the metallic structure of the floor.

NOTE: the frame must be fitted by the installer following theinstructions shown inside the packaging.

LOUVER KIT (optional accessory)The louver is recommended to be used on UNDER units to devi-ate the air flow and allow better distribution.

The "OVER" units are designed for the connections to passthrough the base of the unit; nonetheless, if there is no raisedfloor (units with intake from the rear or front), to simplify theconnection of the pipes and cables, a base moulding mustbe used.The base moulding, available as an accessory, is epoxy-polyesterpowder painted, in the same colour as the external panels on theair-conditioner, measures 200 mm in height and is fitted with aninspection panel.On the right- and left-hand sides of the base moulding are sixpre-cut sections for passing the cables and pipes;The moulding must be fastened to the air-conditioner using theM6 threaded inserts already arranged on the base.

For the OVER units with intake from the bottom, base mouldingsare available with a height of 450 mm.In this case too, the air-conditioner must be screwed to the basemoulding during the positioning phase.

AIR DISTRIBUTION (UNDER UNITS)

INTAKE PLENUM (UNDER UNITS)

DISCHARGE PLENUM (OVER UNITS)


In the units with air outlet from the bottom, the following detailsmust be ensured to allow for sufficient air flow-rate:a) connection opening between the unit and the raised

floor; make a hole in the raised floor and position the air-con-ditioner over the centre of the hole: the air outlet openingmust not be blocked, even partially, by parts of panels, beams,pipes or other objects; insert an elastic gasket around theperimeter of the base to prevent the transmission of noise andvibrations;

b) free air flow along the cavity of the raised floor; theduct represented by the underfloor space must be sufficientlyhigh (at least 200-250 mm of free space, net of the panels andthe beams of the raised floor) and free of obstructions, espe-cially near the air-conditioner;

c) grills and air distribution openings in the room; the airexits the underfloor space through openings or grills, the posi-tion and surface area of which must be proportional to thelayout of the thermal load of the environment.

For units with air outlet from the bottom, the recommended airoutlet speed from the raised floor is between 1 and 2.5 m/s; con-sequently, the cross-section of the grills should be sized based onthis valueThe total outflow area (sum of the areas of the openings and netspace of the grills) required for each model must be calculated bydividing the total air flow-rate (in m3/s) by the required outletspeed (in m/s).

WARNING: the air outlet must be completely free, as aninsufficient air outflow air will reduce the flow-rate, the per-formance of the air-conditioner and may affect reliability.

For ducting the air intake, plenums are available to be fittedbetween the top of the unit and the air return duct or the false-ceiling.

CONNECTION TO BRAZED PLATE CONDENSER AW-AT-AF

WATER CONNECTIONS

CORRECTION FACTORS


AW-AT-AF water-cooled unitsThe condenser must be connected to the cooling water circuit,making sure that the water inlet and outlet connections are cor-rect.If the water temperature falls below the dew point of the condi-tioned air, insulate the pipes with closed cell material (e.g.:Armaflex or equivalent) to prevent condensation; the insulationmust allow access to the valves and the three-piece joints.Seal the holes where the pipes pass through the base of the air-conditioner to avoid the bypass of air.

N.B.: the water system of the unit is PN16

For all the water connections (with the exception of thecondensate drain), the following are recommended:- flexible connections to avoid transmitting vibrations and

allow small movements of the air-conditioner;- joints in three pieces, near the fittings, to simplify the

removal of the unit;- on-off valves to disconnect the unit from the water cir-

cuit: where possible use ball valves with full opening tominimise pressure drop.

(For AW-AT-AF models) check that the cross-section ofthe chilled water pipes and the characteristics of the circu-lating pump are suitable: an insufficient water flow-rateaffects the performance of the air-conditioner.Check that the water inlet and outlet connections are cor-rect. Insulate all the chilled water pipes with closed cellmaterial (e.g.: Armaflex or equivalent), to prevent conden-sation; the insulation must allow access to the valves andthe three-piece joints.

(For AW-AT-AFmodels) check that the water circuit hasbeen filled with an antifreeze mixture containing the rightpercentage of ethylene glycol.

N.B.: Create traps as shown in the figure, making sure to fill them with oil when commissioning the system.Fit a non-return valve at the unit outlet, on the gas outlet pipe.The liquid piping must be protected against sunlight.Install an oil separator for pipe lenght above 350m, (see the OIL SEPARATOR paragraph)

REFRIGERANT CONNECTIONS (AX)


Warning: All work must be performed, components selected and materials used in complete accordance with the legislation in forcein material in the country concerned, and considering the operating conditions and intended uses of the system, by qualified personnel.

The diameter of connecting pipes between the conditioner and condensing unit must be respected, otherwise the guarantee becomesinvalid. Always use large radius curve (bending radius at least equal to pipe diameter)

NOTE: The diameter of the refrigerant lines between the air-conditioner and the remote condenser must be chosen according to thelength of the lines, and therefore this will not always coincide with the inside diameter of the joint to be welded supplied by the manufactur-er. Special care must be paid to the insulation of the hot gas pipes under the raised floor.

OIL SEPARATOR


In the installation of air cooled units (AX-AD) with remote condenser, if the refrigerant pipeline are more than 50mt is recommended toinstall an oil separator on site, in order to avoid that the oil goes away with the refrigerant causing compressor damagesFinally, the use of an oil separator leads to:• a longer life of the compressor;• a better performance of the whole system with consequent energy saving, due the high coefficient of condenser and evaporator perfor-

mance by almost completely removing oil deposits from their exchange surfaces;• a quieter operation by reducing pulsations.

The oil separator have to be selected considering the following parameters:• power cooling of refrigerant system• refrigerant fluid type• the inlet diameter of oil separator have to be equal to the dicharge gas diameter of compressor

POWER COOLING IN kW*

* refered to evaporating temperature +5°C and condensing temperature 40°C

The oil separators have to be installed in the discharge line between the compressor and the condenser mounted securely in a verticalposition and reasonably close to the compressor.Oil separator performs best when operating at or near the compressor discharge temperature. In location the oil separator, choose a posi-tion to avoid, as far as possible, chilling of the shell, which may result in condensing of liquid within the separator. If this is not possible, it isadvisable to supply the separator with the insulation or strap heater to prevent the refrigerant in the system from condensing in the shell.

Acting as the lay out of refrigerating system, the return line may be run from the oil fitting to the suction line upstream the compressor.

A sight glass may be installed in the oil line, in a position that oil is flowing through the tube, to check the correct working of the oil separa-tor. Oil separators must be always pre-charged before its use, as described on the table, with the same oil of the compressor.

CONDENSATE DRAIN

ELECTRICAL CONNECTIONS


The condensate is removed from the pan located underneath thecoil through a hose with drain trap, already fitted in the unit; theend of the hose should be connected to the sewerage system inthe building via a rubber or plastic hose with an inside diameterof 20 mm.

If the air-conditioner is fitted with a humidifier, the condensate isdrained from the humidifier pan, excluding Over units (see thefollowing paragraph).During installation, pour water into the condensate collection panso as to fill the drain trap inside the unit with water.

Correct electrical connection, performed in a workmanlike man-ner and in compliance with the standards in force, is importantfor the prevention of accidents and the good and long-lastingoperation of the air-conditioner.

Before starting the unit, check the tightness of all theelectrical connections and cables on the unit, as thesemay have come loose during handling and transport.

ELECTRICAL CONNECTION OF THE OUTDOOR AIR-COOLEDCONDENSER BRE AND/OR THE OUTDOOR DRY COOLER BDC


It must be stressed that both the standard air-cooled condensersand dry coolers supplied by the manufacturer are not fitted asstandard with the condenser fan speed controller, and are onlyelectrically connected to the disconnect switch for local mainte-nance operations (for further details, see the manual on the out-door air-cooled condensers and dry coolers).Therefore, both of these outdoor units can be powered directlyvia the disconnect switch with primary voltage, however thismeans their operation is not controlled. If the indoor units used are the ACCURATE in MODULATINGversion, complete with condenser fan speed controller, the outdoorair-cooled condenser and/or dry cooler can be connected/powereddirectly from the panel on the indoor unit (the connection cable isnot supplied by the manufacturer).

The instructions on the connection and the size of the powercables are provided by the manufacturer on the wiring diagramon the indoor unit. For both single and dual circuit models, justone connection/power cable is required between the indoor andoutdoor unit. The voltage delivered will be modulated by the con-denser control unit installed on the indoor unit, based on the cur-rent requirements of the system. This ensures optimum operating conditions.The condenser control unit is also featured as standard on theversions of the indoor units for low outside temperatures (-45°C).

For the parameter setting of control condensation referto the manual of the controller EVOLUTION+.

VACUUM AND CHARGE


The refrigerant circuits of the water-cooled chillers and air-condi-tioners are already charged with refrigerant R410A.The air-cooled air-conditioners (AX-AD) and the BRE units thatrequire refrigerant connections are pre-charged with nitrogen (ordry air) to prevent moisture from entering the circuit; in this case,

the refrigerant charge must be completed by the installer, follow-ing the instructions shown in this paragraph.

R410A

Refrigerant (*) Type of oil

(*) recommended with COPELAND compressors.If a circuit already charged with refrigerant needs to be emptied, the first operation required is the removal of the refrigerant from the cir-cuit using a special appliance with dry compressor for recovering the refrigerant. If available, also switch on the sump heaters during theemptying operation.

COMMISSIONING PROCEDUREArm the cutout in the auxiliary circuits;Arm all the cutouts on the electrical panel;Power up the air-conditioner electrical panel and close the maindisconnecting switch on the unit (position 'I');Check that the control board is powered; Check that both theLEDs relating to the phase sequence relay (RSF) are on; the yel-low LED indicates power, the green LED indicates that thesequence of phases is correct.If the green LED is off, disconnect power supply from the units,reverse two phases of the power cable and restart the commis-sioning procedure. (In the units with sump heaters) After having powered up the air-conditioner, wait at least 12hours before starting so as to suitably heat the oil in the com-pressors. During extended shutdown there may be spontaneousmigration of refrigerant to the compressor sump, which at thestart may cause the oil to foam and consequent damage due toinsufficient lubrication.As a result, do not disconnect power during weekly pauses;Open the on-off valves in the refrigerant circuits and check thatthe air-cooled remote condensers are connected (air-cooledmodels); Check that the external radiators are connected andmake sure there is water flow for cooling (water-cooled models);Check that the sections of corrugated pipe with the function ofdrain trap (both inside and outside of the air-conditioner) havebeen filled with water during installation.

AT LEAST 12 HOURS AFTER POWER UP:Start the air-conditioner using the buttons on the user terminal;If an alarm is activated refer to the controller instructionmanual.

Open any valves in the unit or in the system to ensure that all the components are involved in the emptying operation;

Connect a high efficiency vacuum pump to the Schrader fittings or to the 1/4" SAE fittings on the compressor suction and discharge side;

Connect a cylinder of refrigerant to the charge fittings.

Empty the lines, ensuring an absolute pressure of less than 10 Pa (0.07 mm Hg) so as to remove the air and any traces of moisture

The circuit should be emptied slowly and maintained for an extended period, rather than performed too quickly.Wait a "go up time" of 100 seconds and verify that the pressure does not exceed over 200 Pa absolute.In general, if there is the chance of significant moisture content in the circuit or for very large systems, the vacuum must be “broken” withnitrogen dioxide and then repeat the emptying operations as described.

Break the vacuum by pre-charging from the cylinder of refrigerant.After having started the compressor, complete the charge slowly, until the pressure stabilises in the lines and the gas bubbles disappearfrom the flow indicator;The charge must be checked at the environmental design conditions and with a discharge pressure of around 28 bar (R410A); for unitswith on-off condenser control, partially close the intake to stop the condenser fan from repeatedly starting-stopping.Make sure that the subcooling of the liquid at the thermostatic valve intake is between 3 and 5°C less than the condensing temperatureread on the pressure gauge and that the superheating of the vapour at the evaporator outlet is around 5 °C.

OPERATION AND CONTROL


CALIBRATING THE THERMOSTATIC VALVE(air-cooled models)The thermostatic valve is calibrated using the adjustment screwshown in the figure; in the water-cooled models, the correct cali-bration is already performed in the factory.• Check that the subcooling of the liquid at the condenser outlet

is around 3-5°C;• Check that the thermostatic valve superheating value is cor-

rect (around 5 °C);• Check that the valve sensor bulb is correctly positioned,

secured and insulated.If the superheating is above the value indicated previously, openthe valve further; if it is lower, close the valve further.

NOTE: the thermostatic valve must only be calibrated byspecialist personne

WATER-COOLED UNITSWater in an open circuitIf the temperature of the cooling water is not controlled and may fallbelow 25°C, a pressure control valve is required (available as anaccessory) for each condenser; in this case, the supply pressure mustnot be less than 200 kPa (2 bar).IMPORTANT: for systems in which the water is cooled using acooling tower, make sure suitable filters are used, to prevent theplate condensers from fouling quite quickly.Remember that the units are supplied without the sys-tem circulating pump.

Water in a closed circuitThe condensers on the units are supplied with water pumped in aclosed circuit and cooled by external radiators; check that thecross-section of the pipes and that the characteristics of the cir-culating pump are suitable: an insufficient water flow-rate affectsthe performance of the air-conditioner. The temperature of thecooling water must be controlled so as to not fall below 25°C,preferably according to the diagram shown in the figure.Remember that the units are supplied without the sys-tem circulating pump.

IMPORTANT: the cooling water must contain a percentageof ethylene glycol (passivated and consequently non-corro-sive) according to the minimum expected outside tempera-ture. In the Energy Saving models, the use of glycol is alwaysrequired.

CALIBRATING THE PRESSURE CONTROL VALVE


The differential pressure switch F3 must be activated if the fan isnot working (when there is one fan) or one of the fans is notworking.As the difference in pressure between the fan intake and outletdepends on the air flow-rate, the instrument may need to berecalibrated after installation, checking that the contact closeswhen the fan is operating normally.

To calibrate the pressure switch:• simulate a fault in the fan system (stop the fan - if there is just

one - or one of the fans on the unit) and check that the pres-sure switch is activated;

• if the device is not activated, progressively increase the calibra-tion value of the pressure switch.

To calibrate the pressure switch, remove the plastic cover (A) byunscrewing the two screws (B).Use the adjustment screw (E) to calibrate the differential pressureswitch on a scale from 0.5 to 4.0 mbar (50 to 400Pa).If having to replace the pressure switch, unscrew the two fasten-ing screws (D), remove the rubber hoses connected to the pres-sure test points (+) and (-) and remove the electrical cables con-nected to terminals 1, 2 and 3.To install the new pressure switch, perform the same operationsin the reverse order, inserting the cables from point (C).

Pressure switch F4 must be calibrated according to the pressuredrop, which depends not only on the filter being dirty, but also onthe air flow-rate.

The calibration must be performed with a clean filter, as follows:- switch the unit on- progressively cover the surface of the air filter and make sure

that the pressure switch is activated when around 50-60% cove-red;

- if the device is not activated, progressively reduce the calibra-tion of the pressure switch;

- if the device is activated too early, increase the calibration.

Pressure test points

(option available for water-cooled models)The pressure control valve, by managing the flow of water, pre-vents the condensing pressure from lowering excessively and, atthe same time, saves water consumption.If necessary, calibrate the pressure control valve using the adjust-ment knob (the pressure is increased when turning clockwise)until the condensing pressure stabilises at the recommended val-ue of 18 bar (equivalent to a satured temperature of around 45°Cwhen using di R407C) and 27 bar (equivalent to a satured tem-perature of around 45°C when using di R410A), measured using apressure gauge connected to the pressure test point on the out-let valve.

ELECTRIC HEATERS

HUMIDIFIER


ELECTRIC HEATERSThe overall power of the electric heaters is divided into a numberof elements, each with a power of 2÷3÷4 kW.The colour of the wires on each element has the following mean-ing:• BLACK wire = low power element (0.7÷÷1.3 kW);• WHITE wire = high power element (1.3÷2÷2.7 kW);• RED wire = common.The wires for each element are connected to contactors M5 andKM6 on the electrical panel so as to balance the load betweenthe phases and create three stages of power (see the wiring dia-grams on the unit).

If having to replace the electric heaters, disconnect power to theair-conditioner and wait until the heating elements have cooleddown. After having replaced the heaters, make sure the earth isconnected.

SYSTEM COMPONENTS Upon request, the air-conditioning unit can be fitted with an immersed electrode humidifier (versions D and H).

HUMIDIFIER OPERATING PRINCIPLE In the immersed electrode humidifier, the current that runsbetween the electrodes, through the water contained in the boil-er cylinder, generates the heat required to boil the water.By controlling the level of the water and the concentration ofsalts inside the steam cylinder (6) using the fill (7) and drain (8)solenoid valves, the amount of current delivered can be regulated,and measured using a current transformer (2).When steam production is required, the humidifier contactor CUcloses (see the wiring diagram) so as to supply power to theimmersed electrodes. When the current falls below the set value due to the lowering ofthe water level, the fill valve (7) is opened. The drain valve (8) is activated cyclically, depending on the charac-teristics of the supply water, so as to maintain the optimum saltconcentration inside the cylinder (6).The only periodical maintenance operations required are theinspection and cleaning of the parts in the steam production unit. The operations indicated below should be performed annually,preferably before shutting down the unit in summer.

STEAM CYLINDERThe steam cylinder requires periodical cleaning to remove thescale deposits that form on the surface of the electrodes and theflakes that deposit on the filter at the base of the cylinder.To remove the cylinder, proceed as follows:• completely drain the water from the boiler; to do this, see the

paragraph “MANUAL CONTROL” in the EVOLUZIONE con-troller instruction manual;

• disconnect the power supply by opening the main switch on theelectrical panel;

• remove, from the top of the cylinder, the hose that carries thesteam to the distributor;

• disconnect the power connections by unscrewing the knobs onthe cable ends and remove the plugs from the level electrodes;

• release the strap that secures the cylinder to the unit;• slide the cylinder out upwards.The steam cylinder can be reused a number of times after clean-ing the electrodes: if, however, the wear on the grills of electrodesis such that these cannot be regenerated, they must be replaced.The only spare part is the complete cylinder body (with filterincluded).

FILL AND DRAIN ASSEMBLIESTo ensure the correct operation of the humidifier, the supply/filland drain assemblies need to be inspected periodically.Proceed as follows:- completely drain the water from the boiler using the MANUAL

CONTROLS on the controller A1;- disconnect the power supply by opening the main switch on the

electrical panel;- remove the fill pipe from the 3/4 GAS fitting on the fill solenoid

valve;- remove and clean the filter located inside the solenoid valve fit-

ting;- dismantle the drain assembly (shown in Figure 13), clean the

pipes and remove any flakes of scale from the cup-drain trap.

HUMIDIFIER POWER SUPPLY


Underneath the fill solenoid valve on the steam production unit isthe threaded male fitting (V) for the humidifier water supply. This is already fitted with a plastic hose, diameter 6 mm, for con-nection to the building's water supply (see figure, point F).

V: Steam production unit - inlet connection (threaded male fit-ting 3/4”G);

F: Rubber hose, diameter: Ø 6mm.

To supply the humidifier, use drinking water without any chemicaltreatment or demineralisation.The characteristics of the water that supplies the humidifier mustbe within the following values:

(1) Values depending on specific conductivity; in general: TDS ≅ 0,93 * σ20; R180 ≅ 0,65 * σ20

(2) not lower than 200% of the chloride content in mg/l of Cl-

(3) not lower than 300% of the chloride content in mg/l ofCl-

The cylinder supplied as indicated in the price list refers to the model for medium conductivity (350...750 µS/cm). Models are available upon request for low conductivity (125-350 µS/cm) or high conductivity (750-1250 µS/cm). Contact the office to a specific quotation.

HUMIDIFIER AND CONDENSATE DRAIN

Underneath the drain solenoid valve on the steam productionunit is an attachment for draining the water. This is already fitted with a hose coupling for connecting the hoserunning to the sewerage system in the building.A rubber or plastic hose should be used, resistant to 100°C, withan inside diameter of 32 mm.Fit a trap in the section of the hose outside of the unit to avoidbad odours and to prevent water from overflowing from thehumidifier pan.During installation, pour water into the condensate collection panand the humidifier pan, so as to fill the drain traps outside andinside the unit with water.Downstream of the drain trap ensure a minimum slope of 1%.

WARNING: the water exiting the steam cylinder is very hot.The humidifier drain hose must not be fastened to electricalcables and must run down vertically so as to avoid any contactwith these cables.

CONDENSATE DRAIN PUMP AND HUMIDIFIER DRAIN PUMP

STD CONDENSATE DRAIN PUMP (LOW WATER TEMPERATURE)


Depending on the version, a condensate drain pump is available(for versions B and R) or a humidifier drain pump (for versions Hand T) with mechanical features such as to be able to resist thehigh temperatures of the water exiting the steam cylinder.

The pump must be located below the drain fitting, according tothe instructions contained in the packaging.Check that the head is sufficient to lift the condensate to thepoint of drainage.

The pumps with tank are designed to collect the condensate pro-duced by the air-conditioning unit. These start automatically when the float rises and have a dis-charge head of 4 metres.The pump is fitted with two switches, activated by a float system.One is used to start the centrifugal pump, and the other is usedas a high level safety switch.The top part of the pump is made from transparent plastic, forquick and easy inspection of the internal components, and is sup-plied with a 2 metre long cable with push-in quick coupling tosimplify installation and maintenance.In any case, the pump with tank must be installed below thesource of condensate.

Make sure the hoses are not choked or twisted along the pathbetween the pump and the point of drainage. Securely fasten the hoses with a clamp to the pump outlet fitting,to prevent them from coming loose and consequently causingwater to be released at high pressure.

IMPORTANT:1) The safety switch should always be used2) The drain pump should be powered separately from the unit

that produces the condensate, so as to allow the pump to con-tinue draining the water even if the unit itself shuts down.

Maintenance guideAt least once every 6 months, pour a bactericidal solution intothe tank, to prevent accumulation of residues and sludge at thebottom. These substances may cause the float to malfunction or block thenon-return valve that the drained water flows through.

NB: Users must check that any chemicals contained in the con-densate are compatible with operation of the pump.• Do not use the pump to drain water at temperatures exceeding

50 °C.• Do not use with demineralised water (this has been proven to

damage the mechanical parts of the pump)

IMPORTANT:Test pump operation by filling it with water until the motorstarts, to check for any leaks and verify correct drainage of thewater.

DISMANTLING

MAINTENANCE

IMPORTANT INFORMATIONS FOR COR-RECT DISMANTLING OF THE UNITACCORDING TO CE 2002/96/CE

If the unit has to be dismantled, this operation must be done bysuitable local authority. The correct dismantling avoids any nega-tive enviromental consequences and allows significant benefits interms of energy saving and resource.

Every components replacement (compressor, safety presso-stat, liquid receiver, ecc.) have to consider the main compo-nent list enclosed in the unit.

This section, aimed above all for the end user, is extremely impor-tant for the correct operation of the appliance.Just a few operations completed scrupulously and regularly willavoid serious damage to the components. Only authorized andspecialist personnel can operate into the units.The maintenance operations can be summarised as follows:- Clean the air filter.- Check and clean the condenser coils- Check the water-cooled condensers for fouling.- Check and clean the drains.- Check the humidification system.- General examination of the overall operation of the appliance.- Visual check of the condition of the pressurised containers.

Cleaning the air filterThe gradual fouling of the filters reduces the flow-rate of the con-ditioned air, with a consequent reduction in cooling capacity.In the direct expansion units, a reduction in the air flow-rate maycause the activation of the low pressure switch and/or cause seri-ous damage to the compressor. This can be avoided by the peri-odical cleaning of the filters. The frequency at which the filtersmust be checked exclusively depends on the amount of dust inthe environment. In any case, the following are recommended:- Every week check that the filters are clean - Every two weeks clean the filters with a vacuum cleaner - Every month wash the filters with soapy water- Every 6 months replace the filters.It is clear that the recommended times are purely indicative, andin some cases it may be necessary to increase the frequency ofthe checks and maintenance operations. These operations must be carried out with the unit off and afterhaving made sure that the appliance is disconnected from thepower supply.

Checking and cleaning the condenser coilsIn the hotter period, when the unit operates at maximum capaci-ty, the condensing coils must be able to offer the maximum heatexchange. Normally installed outside or communicating with theoutside, these may pick up dirt such as paper, dry leaves and dust,thus reducing the heat exchange. Make sure that this situationdoes not arise. Failure to perform maintenance will cause the acti-vation of the high pressure switch and the unit to shutdown.Frequently check the condition of the heat exchanger during thepoplar pollination period or the autumn (falling leaves).Remove any objects accumulated on the coil and wash with a jetof water. These operations must be carried out with the unit offand after having made sure that the appliance is disconnectedfrom the power supply.

Checking the water-cooled condensers for foulingTo check the water-cooled condensers for fouling, simply checkthe water inlet and outlet temperature and compare it against thecondensing temperature. Normally, for good heat exchange, thedifference between the water outlet temperature and the con-densing temperature must be 5.8°C. Increases in these values,over time, indicate a reduction in efficiency and consequently thefouling of the condenser. The condenser is cleaned by chemicalwashing and must be performed by specialist personnel. Thisoperation must be carried out with the unit off and after havingmade sure that the appliance is disconnected from the powersupply).

Checking and cleaning the drainsAll the water drains (humidifier and condensate) must ensureperfect drainage, to avoid flooding in the room.When the humidifiers drain the water, they discharge a quantityof lime scale that depends on the hardness of the supply water.This lime scale may accumulate in the bottom of the drain hoseand block the flow of water. If cleaning is required, add ordinarydescaler to the section of circuit involved. This operation must becarried out with the unit off and after having made sure that theappliance is disconnected from the power supply.

General examination of operationThis is a general examination aimed at comparing the operationof the appliance with the last check performed. Consequently, anydifferences in the operating characteristics over time can be high-lighted. A detailed and periodical visual check of the appliance andgeneral cleaning are always important to ensure correct opera-tion. The above-mentioned operations can in general be per-formed once a month. Naturally, in special situations and specificinstallations the frequency may change. A well maintained systemis unlikely to cause disruptions and stoppages to the productioncycles. After 10 years working a complete checking is recom-mended.

Visual check of the condition of the pressurised contain-ersCheck the condition of the pressurised containers at least once ayear (if these are fitted). It is very important to check that rustdoes not form on the surface, that there is no corrosion and thatthere are no visible deformations. If not controlled and stopped,surface oxidation and corrosion will over time cause a decreasein the thickness of the container and a consequent reduction inits mechanical strength. Protect with paint and/or corrosionproofing products. In the event of visible deformations, stop theunit and contact the nearest service centre.

TROUBLESHOOTING


Troubleshooting is simplified by the information provided by themicroprocessor controller: if an alarm is signalled, refer to thecontrol panel instruction manual.
