1 General Information

The systems manufactured and designed by LPG for fire extinction by means of iFLOW, are meant to besolid, reliable and easy to assemble systems, thus allowing the checking of their performance following

the operation step included in this manual.However, LPG Tcnicas en Extincin de Incendios, S.A. clarifies the following issues:

Every single person who deals with the start-up, inspection, testing and maintenance of the systemsmust be well trained in order to perform the different checks. LPG always recommends the adoption ofsafety practices according to the current legislation on health and safety procedural issues. It is alsoadvisable for the personnel in charge of the installation and maintenance of the fire extinguishingsystem to receive precise training on the safety area as well as to carry out both a complete andcareful reading of this manual before engaging into any of the described operations.

Every single person who works in a monitored protected zone by means of iFLOW must be informed

of the fire extinguishing agent properties and its possible effects both on people and protected goods.The personnel who work in the protected zone must be instructed on how to proceed in the event of apossible alarm and in the different types of systems activation.

Throughout the installation and maintenance operations, the workers must wear industrial clothingand safety footwear. When necessary a helmet and gloves must also be worn. Whenever the workersare to drill holes for the pipe supports or for the positioning of the cylinder racking brackets, it is alsocompulsory the use of safety goggles or a mask. This protection is also applicable when someoperations are to be carried out which may cause shedding of particles.

Due to possible false alarms of the detection system (if any) produced by the dust or the smokecaused by installation works, the detection system of the zone shall be either isolated or disconnectedbefore and during the assembly operations.

The whole equipment and piping network must be installed according to the project design. Anymodification of the design must be approved in writing by the client and the responsible engineeringcompany. The modifications must then be included in the project.

WHENEVER A CYLINDER IS BEING TRANSPORTED, MAKE SURE THE VALVE PROTECTION CAPIS ALWAYS FIRMLY AND TIGHTLY SECURED.


7/139


Use one or some of the following materials as thread sealing elements:

Thread sealing compound for 0.4 mm clearance.

Teflon tape.

Regardless of the sealing element used do not ever cover the first two screw threads in order to ensurethe cleaning of the inside part of the piping network.


8/139


2 Installation

During the assembly of the system, it is advisable to always use the installation designs supplied with thedelivery of components so as to understand the system thoroughgly.

As an example, the standard designs with the different iFLOW bank models are included in Annex I.Inthese, it is possible to see the layout of the cylinders bank, the connection of the simple release systemand the layout of the standard support systems. Note that specific designs will always prevail to theseexample ones.

Proceed to check against the design plans and the materials lists whether all of the components havebeen supplied. Check also that none of the components are damaged. Any defective component must bereplaced. Examine the position of the cylinders and the pipe sections in the design plans and check thatno physical barriers are to be found which may require some modification of the cylinders, the brackets orthe pipe sections. The project engineering must be informed of any deviation with respect to the designplans.

Before assembly of the installation, check the position of the bank (usually indicated in the design plans).The most advisable position of the bank is the nearest room but away from the protected risk. It should

also be large enough to house the equipment as well as to make the assembly and maintenanceoperations possible. The equipment must not be exposed to severe climate conditions, direct action of theflame or to a too humid environment. It must be located away from unauthorized handling and mechanicalor chemical aggressions.

INSTALLATION:

On carrying out the installation, it is important to consider the following issues:

Sweep the floor on which the bank/battery will be assembled. Check the sizes on the design plansand make sure that the bank system fits perfectly in the chosen position.

The floor on which the bracket will be assembled must be as flat as possible.

The wall where the bracket will be fixed (in case it should be necessary) must be at right angles tothe floor and it will be solid (avoid partition walls, Pladur or similar ones).

In the event of having to fasten the bracket to a partition wall it will be necessary to prepare someiron plates which shall allow fastening of the bracket from the other side of the wall as shown inthe picture:

The assembly of the brackets and the position of the manifold depends upon the bracket havingside columns and upon the connection to the piping network being horizontal or vertical.


12/139


2.1.2 Installation of brackets

LPG supplies its equipment together with a bracket support system for the cylinders. These consist ofthree types as follows:

A) Brackets with a vertical support column

B) Brackets without vertical support column

C) Brackets for specific individual cylinders

Within these types there are also different models in order to adjust the requirements of the suppliedsystem. In this manual you will find general guidelines for each type of installation. To carry out theinstallation in situ refer to the design plans supplied with the equipment and take into accountinstructions in this manual..

Attention: Always carry out the final installation of the brackets, cylinders and manifold

befote connecting the manifold pipe and the nozzle network. This measure preventsfrom many adjustment problems Turing installation of the different components of the bank.


13/139


The characteristic feature of these type of brackets is that they incluye the vertical support column whichcan be directly fixed to the wall and/or the floor. Such configuration gives solid stability to the overallcylinder bank.

The following bracket models are included within this type of bracket:A) Single raw Bracket :All cylinders in this bank are aligned in one single raw and the weight of themanifold pipe lies on the bracket structure.

B) Double raw Bracket:All cylinders in this bank are aligned in two parallel raws and the weight ofthe manifold pipe lies on the bracket structure.

The following issues should be considered when assembly of these brackets:

1. A design plan of the system is supplied together with the equipment and at least one bracketexpanded plan. It is necessary to understand these plans perfectly before starting the assemblyprocess.

2. In these plans the bank size is always indicated. Even so, it is advisable to check beforehand toensure that the structure fits in the assigned area.

3. Clean the area where the installation of the brackets will take place.

4. Following the design plans, carry out a preassembly of the estructure on the floor., particularly thecomponents that are closer to the wall.

5. For preassembly, it is necessary to consider the fixing system and the different components of thestructure. The vertical support column has some lugs threaded in the sides which are useful to holdthe banks crosspieces. For the correct joining of the vertical support column and the crosspiece seethe following figure:

Attention: NEVER start the bracket assembly by conecting the manifold pipe with the piping network for the nozzles. This often causes problems of adjustment duringinstallation

6. The manifold supports1are directly assembled on the vertical columna and they may be differentdepending on the bank modelo or their position in it.. Refer to the design plans for the exactposition of each of them.

7. Once the preassembly is done, place it in its final position taking into account the necessarydistance to conect the manifold pipe with the piping network for the nozzles. After getting the rightposition, fasten all screws ensuring the union between the vertical support columns and thecrosspieces. This will give th estructure stability. Then level the different components both

vertically and horizontally to get the bracket right placement.

8. Place the two bank cilindres furthest to each other within the bracket and hold them to it. Forbanks of less than 8 cylinders, one can be the master cylinder. Guide the valve outlet asindicated in the design plans.

9. Place the manifold on their supports or seats. Caution: The entire system is still not fixed orsecured in some parts of the building. Take appropriate measures to prevent the whole set fromfalling.

10. Place the manifold check valve for each of the cylinders. There is no need for the final assembly ofthese elements.

11. Place the discharge hose between the cylinders valves and the check valves. There is no need forthe final assembly of the hoses.

1Manifold support: Metal piece bearing the manifold pipe weight . Is is squared and it is always assembled on the vertical supportcolumna.

NOTE: WHENEVER A CYLINDER IS BEING TRANSPORTED, MAKE SURE THE VALVE PROTECTION CAP IS ALWAYS FIRMLY AND TIGHTLY SECURED.

NOTE: To avoid accidents Turing the installation of the system fix the manifold support to the column slightly threading the locking screw already built in the vertical supportcolumn.


15/139


12. Find the best position of the manifold with respect to the position of the release hoses. Once theright position is found, this will be the final position of the bracket. Always check against the bankdesign plans. However, for an exact adjustment, all cylinders may need to be turned a little butalways in the same direction.

13. Check the vertical and horizontal level of the cylinders and the Bracket assembled piedes beforemarking the fixing points on the floor and wall. Drilling is possible as long as we are guided by thefixing drills in the bracket. Fix the bracket in its final position. Fixing either to the floor or the wallmay require the use of high power chemical or metal raw plugs. In any case, the fixing should bedone with suitable means depending on wall type etc. .

14.Assemble the rest of the bank cylinders on the Bracket and complete the methallic structure. It isvery important that all the cylinders go in the same direction and that they are all vertically leveledto avoid subsequent problems when placing the release hoses.

15. Fasten the locking screws. Once the system is mounted, if necessary drill the vertical supportcolumna and the manifold support and screw on as follows.

16. When all the cylinders are mounted together with its hoses and check valves and the whole set iffixed and fastened, then connect the manifold pipe and the network of nozzles.

17. Carry out the installation of the rest of the bank elements according to the detailed instructionsgiven further in this manual.

2.1.4.13 Release system for directinal valves

DESCRIPTION:

The installation of directional valves (1.2) in the discharge manifold (3) can cover a number of risks with asingle bank. The connection of the release system for directional valves will depen on the number ofdirectional valves and the number of cylinders to be discharged through each of them. Use the specificinstallation plan for the system being mounted. In the example shown in the figure, the bank covers twoareas of fire risk. Both areas require the four bank cylinders for its protectin. Once the pilot cylinder (6) isreleased, the gas flows towards the solenoid valves + manual release (4,5).

- When the activated solenoid is the fourth, the gas will flow until the directional valve (1) whichwill open and the gas will keep on flowing thourgh the release line until the four cylinders openup. The iFLOW

agent is discharged in the manifold and released through the opened

directional valves (1) towards the piping network directed to the corresponding zone.

-

When the activated solenoid is the fifth (5), the running of the bank is similar to the previouscase but discharge occurs through the directional (2).

The solenoid valves + manual release (4,5) can be activated manually when there is an electrical failur. Itis important that each valve is marked with the protected zone it serves to avoid confusion in case ofmanual activation. The connections between the pilot and cylinders are performed in copper tube (7). Atthe release line outlet of the directional valve there is a non-return valve (8). The release line iscomplemented with a decompression screw (9) and a decompression valve (10).


52/139


ASSEMBLY:

Once the storage system is installed (bracket, cylinders, manifold, directionals and connection amongcomponents) proceed to assemble the release system: Fix the bracket of the pilot cylinder and hold the

cylinder to it (6). Mount its support (11) and place the solenoid valves + manual release (4,5).

Mount the penumatic release cones (12) in the cylinders. Mount the tee T of the pilot cylinder outlet,decompression valve (10) and decompression screw (9). Join the cylinders through the flexible hoses(13). Finally, install the cooper tube line (7).

The copper tubes must be straight or bent to 90 degrees. Check that bends in tube are not damaged orcrushed in the corners so as not to strangle the passing of pressure. In longer sections than 1500 mmmake an expansion bend in the middle, ie a full circle to soften the ram effect or hammering. The closureof the copper lines is performed by a bicone. Mount the bicone to the copper tube on a workbench not inposition, to ensure the correct bite of the bicone onto the tube and thus avoiding leakage.

Once adjusted on bench, mount on the circuit by ensuring that the tube and the bicone reach the bottomof the coupling and tighten the nut with a fixed wrench.

As far as electrical installation is concerned, it is important not to confuse the electrical connections of theset solenoid valve + manual release (4 and 5). In case of a wrong connection of the whole set, it ispossible that the extinguishing order given by the detection system produces a discharge of theextinguishing agent for a different risk from the one required. For this reason, each solenoid should beidentified accordingly.

Bicone union typeExpansion bend

IMPORTANT: It is advisable that the length of the solenoid wires be such so as to avoidconfusion of their respective positions (the longest wire is for the furthest solenoid and theshortest for the closer solenoid).


53/139


TESTING:

During installation of the directional valves, manually check the route of each direccional of the system. Inorder to do so, open and close the valves to make sure that they are clean and there is no loose or hittingparts (walls, copper tube lines, copper tubes, etc.). (See section 4.2.6)

PNEUMATIC TESTING

Refer back to the graph included at the beginning of this section.

1. Disconnect the pneumatic feeding between the directionals and the release heads by their side.Repeat this operation for all directional valves to avoid any accidental releases.

2. Block the free extremes of the tubes feeding the release heads.

3. Disconnect the pneumatic feeding between the el botelln piloto (6) and the solanoid valve +manual release (4 or 5) by the side of the cylinder. Connect a nitrogen pressure source in its placeor clean and dry compressed air at a pressure of 10-15 bar.

4. Slowly open the passing of pressure from the source. At this point the pressure is held by thesolenoid valve + manual release (4 and 5).

5. If the coil of one of the solenoid valves is activated or shaken, for example (4) with the indicatedtension source, the associated direccional valve (1) should open due to the effect of the pressure.

At this stage, check the tightness of the pneumatic circuit with the help of soapy water.

6. Cut off the pressure suply from the source and depressurize the line by shaking the testedsolanoid valve (4). To finish the operation, close the directional valve manually with the help of alever already supplied with the system.

7. Repeat the process with all the system direccional valves.

8. To conclude, leave the pneumatic release system connected as specified in the drawings. Payclose attention so that the connections between the directionals and the cylinders of the bank are

not mixed up.

2.1.4.16 Supports

Every installation shall have a minimum of two supports to hold pipe system. Maximum distance between two supports along pipeline shall never exceed the following values:

NominalDiameter (mm)

Nominal Diameter(inches)

Max. distance

between supports(m)

10 3/8 1.0

Whenever pipeline is more than 2 inches (DN 50) and table distances cannot be adhered to becauseof design reasons, these distances may be extended to 6 m between supports, provided that the

pipeline has double supports.

Pipe supports should be placed closely to the pipe couplings, elbows and reversals.

Supports shall connect the pipe system directly to building structure and shall not be used to supportother objects. The parts of the building where supports are fixed shall be strong enough to take theload (see table for design charge). Otherwise, additional straps shall be fixed to other resistantelements. Only pipes with nominal diameters less than or equal to 50 mm may be attached to metallicstructures in the shape of trusses or concrete slabs (design shall be approved by the authorities).Fastening plugs in concrete slabs shall be located at least 150 mm away from the edge of slab.

The distance between the nozzle and its support shall be the shortest possible:

- For pipelines with a smaller or equal diameter than 25 mm, the maximum distance fromsupport to nozzle shall be 0.1 m.

- For pipelines more than 25 mm diameter, the maximum distance from support to nozzleshall be 0.25 m.

Supports type hangers or manifold "U" fixation are recommended. Pipe brackets and other supportfittings shall completely surround the pipe and be closed.

Supports shall comply with the following minimum requirements for sectional areas and depthanchoring:

2.1.4.17 Nozzles (Data sheet code 135 & 136)

DESCRIPTION:

Nozzles perform the discharge of extinguishing gas inside the protected zone. They consist of analuminum discharge head containing a multiple number of orifices inside of which a diaphragm is fittedwith one single calibrated orifice. Such orifice is designed to achieve an optimum distributioon of gas. Thepressure of the pipe downstream the restrictor will depend on pressure loss of the pipe and the orificehole taking place in the diaphragm. The orifice must be calibrated according to hydraulic calculation foreach installation.

Nozzle 360 Nozzle 180

Fig. 2.1.4.16. Nozzle

ASSEMBLY:

Place the diaphragm inside the nozzle and block its position through an Segel type elastic washer(supplied with the nozzle and diaphragm). Apply thread sealing compound or Teflon tape to distributionpipeline thread. Connect the nozzle and tighten with the help of a fixed wrench.


60/139


To avoid mistakes during installation, all nozzles should should incorporate legible and long-lastingmarkings with detail of the calibrated diameter of the diaphragm and an identifier of its position on the planwith respect to the project and the system hydraulic calculations. LPG typically performs a mechanicalengraving (punched) with details described above on the diffusers body.

2.2 Electrical installation

After performing the installation pneumatic assembly and with the pilot valve top caps dismantled,perform the electrical connection of components requiring so. When these components are fed through a

control station, it is recommended to carefully read the instructions for the station installation to avoidaccidental activation of electrical devices which, in some cases, may cause full discharge of the wholecylinder bank.

Electrical connection of Pressure switch with interlock :

For a normally closed circuit connect to 21 and 22 terminals. For a normally open circuit connect to 13and 14 terminals

NOTE: It is very important that nozzles are fastened correctly and that they never face false ceilingsor other mobile parts, otherwise the output of gas could lift ceiling tiles ordrag objects. Never place a nozzle directly in the discharge outlet of the valve.

NOTE: LPG electrical components do not have polarity. All connections shall be performed in such way that the cables reach right to to the device to avoid confusion ofcables for subsequent maintenance or commissioning operations.


61/139


Electrical connection of Solenoid valve:

Make sure that the electrical power supply is disconnected during electrical connections that the top capis removed. Connect solenoid valve as shown below:

Once connected, place back the top cap of the pilot valve.

Pressure Gauge with electrical contact:

Specifications:

Voltage: 4.5 - 24V C.C

Current: 5 50 mA

Max. consumption: 3 W

In the case of pressure gauges with contact for remote monitorization of the cylinder pressure, connectthem as shown in the following drawing:

Direct connection to station

LPG pressure gauges are normally opened when they working with pressure. The R1 resistance shouldalways be installed at the end of the line. Please, refer to the user manual of the control panel to obtain thesuitable values of the R1 resistance.

There should be an ongoing supply of 24 V C.C. When the circuit is in service (connected to 24 V CC) ared LED remains on. If not, check light connections and polarities. If the problema persists, please contactLPG.

The pressure gauges should be connected in parallel to the INVERTER circuit through the PRES port: thecontrol panel will be connected to the INVERTER circuit through the OUT port. Once the pressure gaugesare connected to the INVERTER circuit and the R1 resistance is also connected, the green LED will remainon and the contects to the central 1 will remain closed. If not, check electrical connections and verify thatthe cylinders have the correct pressure. If the problem persists, please contact LPG.

In the event that the gauges PRES circuit opens or short circuits (detected the loss of cylinder pressure)the contact to central 1 will open causing an alarm in the control panel. Then, the green LED switches off.

Electrical connection of the exploders and firing pin (protractor):

The exploders have two feeding cables that should be connected to the activation line.

Nominal Intensity: 1.2 A

Minimum Intensity: 1.2 A

Intensity of test security:


64/139


In the case of firing pins (protractors), two feeding cables are included and they should beconnected to the activation line. The connection is made in the same way as the exploders, theelectrical data of which are listed below:

Nominal Intensity: 1 A

Minimum Intensity: 0.35 A

Intensity of test security:


65/139


2.- Serial connection of various items:

According to factory requirements, the intensity of current for serial connections within the circuitshould be 3 Amp.

The maximum number of items to connect is determined when not connecting Rr (Rr =0).

3.- Parallel connection of various items:

U = Voltage in volts.

Rr = Resistance in Ohms.(W

).

rp = Resistance of item in Ohms.(W).

I = Intensity required to the power supply

IL= Intensity required for each line.

UL= Voltage per line.

Example: Power supply 24 V / 3 A.

rp =1.6 W.

IL= 1 Amp

Applying this formula Rr = 22.4 W.

Given that the power supply is 3 Amp, and each line

requires IL= 1 Amp, maximum 3 lines can be
