2 MANU A L U TI L I Z A TI O N .

There are two different useful ways of how to use this manual. Firstly, following the indexaccurately (mainly when is the first system to be installed and the personnel has noprevious experience) and secondly, as a reference book. In both cases, it is necessary theuse of the drawings provided with the system as a reference.

In the first case, the manual layout allows the installation of a system chronologically. It isalso convenient to refer to the drawings in order to identify the position and number of thecomponents to be installed.

As for the second case, this manual is used when the installer, with previous experience,checks in the first place the drawings provided with the system. Since the denomination andtechnical data sheet of each part appears in them, each component is easily located in theindex and therefore, the appropriate chapter can be consulted.

Intention of this manual is to give specific instructions for installation, maintenance andtesting requirements for LPG systems and components. In any case is intended toaccomplish any requirements of the applicable and mandatory standards of design andinstallation of systems.

3 GENERAL .

Carbon dioxide (CO2) fire extinguishing systems manufactured and designed by LPG aredesigned as heavy duty equipment, reliable and easy to mount, with simple test routines tocheck their operating condition as described in this manual. However, LPG Tcn ic a s e nEx t i n c i n d e I n c e n d i o s S .A . wishes to clarify the following:

All personnel who are assigned to the equipment should be properly trained in itsuse, inspection, tests and maintenance. LPG recommends at all times the adoptionof safe working practice in accordance with current health legislation and safetyprocedure. It is recommended that personnel in charge of installation andmaintenance of the fire extinguishing system should be properly trained in its safeuse and should read the whole of this manual before initiating any of the operationsmentioned above.

All personnel working in an enclosure protected by carbon dioxide (CO2) systemsshould be warned of the effects on personnel and protected properties. Personnel inthe protected area should be trained in the modes of actuation in case of alarm andin the different types of system activation.

During installation and maintenance operations personnel should be protected bywearing protective clothing and shoes and when necessary helmet and gloves. Safetyglasses or facemask should be worn whenever holes are drilled for pipe supports orcylinder bank brackets. Such protection is also needed when dealing with particleemission.

Due to possible false alarm of the detection system (if installed) produced by dust orsmoke caused by installation works, the detection system in the area should beisolated or disconnected prior to staring and during the assembly operations.

All the equipment and pipe system should be installed in accordance with the projectdrawings. Systems are made up of units tested within limitations. The systemdesigner must be consulted whenever changes are planned for the system or area of

protection. Constructive drawings should be corrected and modifications included inthe project.

An authorized installer or system designer must be consulted after the system hasdischarged.

P r o t e c t i v e c ap m u s t a l w a y s b e i n s t a l le d o n t h e d i sc h a r g e v a lv e w h e n ac y l i n d e r i s b e i n g t r a n s p o r t e d t o i t s f i n a l d e s t i n a t i o n .

Use one or several of the following as thread joint compounds.

- 04 mm thread joint compound.

- Teflon tape.

Whichever sealing compound is used, never cover the two first threads to ensure internalcleanliness of the pipe system.

4 DESCR I P TI ON OF CARBON D I OX I D E ( CO 2) SYSTEM S.

Centralised carbon dioxide (CO2) fire extinguishing systems manufactured and designed byLPG are developed as reliable equipment and easy to mount.

LPG centralised systems consist of 4 elements:

Storage Systems.

Comprising steel cylinders containing the extinguishing agent.

Release System.

Controls the activation and later discharges the gas contained in the cylinders.Consists of a pilot valve, which integrates the different release devices, such as

manual release, solenoid valve electrical release and pneumatic release, whichcontrol opening of cylinder valves or slave cylinders. It is a flexible system thatallows the installation of more than one pilot valve. This system can actuatesimultaneous batteries depending the necessity.

Distribution System.

Directs gas discharge from the cylinders to the protected zone.

Support System.

Consisting of a metallic structure (brackets), which supports the cylinder block.According to the configuration there are single row and double row models.

All personnel who are assigned to this equipment in commissioning, inspection, tests andmaintenance operations should be thoroughly trained in the functions they perform.

The number of carbon dioxide (CO2) cylinders required to protect the hazard area isdetermined by specific calculation for each application.

All systems may be actuated automatically by means of the solenoid valve or manually.Manual actuation systems incorporate devices to prevent accidental discharges.

Personnel in the protected area should be instructed in the modes of actuation in case ofalarm and in system manual actuation.

4 .1 SYSTEM 1 : CYL I ND ER BANK OF 8 OR LESS CYL I ND ERS OF 40 2 &6 7 L I TRES .

(As reference see drawing 50040676 St a n d a r d b a t t e r y f o r 4 0 2 6 7 l CO 2C y l in d e r2 R w i t h o u t w e i g h t i n g d e v i ce a n d p i lo t c y l in d e r included in Annex I)

A master cylinder is one of the bank of cylinders and is filled with the same contents as anslave cylinder. In this system pressure released at the opening of the master cylinder isdirected towards the pneumatic release heads of the slave cylinders used to discharge allthe valves together. LPG 128-20 valve (technical data sheet Nr. 140) is used on mastercylinders. LPG 110-00 and LPG 110-10 (technical data sheets Nr. 006 and 007) are used forslave cylinders.

The pneumatic release system incorporates a non-return valve to maintain the optimalpressure level for the activation of all the cylinders and a device to safely vent of residualpressure in release pneumatic circuit.

The control panel via a solenoid valve may actuate the system automatically. For manualactuation it is necessary to access the Master cylinder release, remove the safety seal and

pull the lever.

(As reference see drawing 50090673 S t a n d a r d b a t t e r y f o r 4 0 2 , 6 7 l CO 2c y l in d e r s 1 R w i t h o u t w e i g h i n g d e v i ce a n d p i l o t c y l i n d e r included in Annex I)

A pilot cylinder of reduced volume filled with dry nitrogen at 100 bar is used. In this casethe pilot cylinder contents are not used as effective extinguishing agent. The pressurereleased at the opening of the pilot cylinder is directed towards the pneumatic release headsof the slave cylinders. Valves used on the pilot cylinder is or LPG 128-90 (technical datasheet Nr. 132). Slave cylinders are fitted with LPG 110-00 and LPG 110-10 valves (technicaldata sheets Nr. 006 and 007).

The cylinder bank is delivered fitted with devices to prevent actuation through micro-leakage a well as controlled release evacuation of residual pressure in the pneumaticrelease circuit.

The control panel via a solenoid valve may actuate the system automatically. For manualactuation it is necessary to access the pilot cylinder manual lever release, remove the safety

seal and pull the lever.

After a real system activation it is necessary to release residual pressure trapped within thepneumatic release circuit. Therefore, see instructions for the use of the DecompressionScrew in section 8.3.6. in this Manual, Release Line Decompression.

Selector valves may be adjusted to any system described above.

These cylinder banks consist of a manifold discharge pipe which incorporates a lengthspecially designed and fitted with the required couplings for the selector valves. The selectorvalve pneumatic supply system is made of 4 x 6 mm diameter copper pipe. In accordancewith the design requirements primary and reserve storage systems with selector valves maybe used. The exact number of cylinders to be discharged in each hazard area may bedetermined also.

A selector valve system always consists of a pilot cylinder filled with dry nitrogen at 100bar. Actuation may be automatic via the control panel and solenoid valve or manually. Inthe event of automatic actuation, the pilot cylinder solenoid valve and solenoid valves +selector valve manual release actuation are activated at the same time.

In the event of manual actuation it is necessary to have access to the solenoid valve +selector valve manual release protecting the hazard zone, remove the safety seal and pullthe fitted lever. Later remove safety seal on pilot cylinder manual release lever and pull thelever.

The valves as well as the pneumatic actuation system are identical to those described inSystem 2.

4 .4 SYSTEM 4 : CY LI NDER BANKS PROV I DED W I TH W EI GH I NGSYSTEMS.

(As reference see drawing 5105067N Standard Batery for 67 l CO2 1 R withmechanic weighing device included in Annex I)

A weighing system may be fitted to any of the systems described above This system can be

mechanical or electronic by cell.Due to the vapour pressure of carbon dioxide (CO2)(572 bar at 20 C, 067 and 075 kg/lfill density according with NFPA 12:2000; CEA 4007:1997-08 and CEPREVEN R.T.4. CO21998) it is not necessary to super pressurise cylinders with dry nitrogen to obtain fullcylinder discharge. Therefore, the cylinder internal pressure does not depend on thequantity of gas contained. In this way it is not possible to detect leakage just by viewing thevalve gauge. To control the level of carbon dioxide (CO2)content in the cylinder bank, LPGhas electronic and mechanical weighing device systems available to continuously control theweight of each of the cylinders. In case of leakage or discharge of cylinders, the weighingdevice system emits an alarm signal.

Both weighing device system allows alarm monitoring via external systems (control panel or

main control).The use of a weighing device system does not require valve modification or modification ofactuation modes described above.

(As reference see drawing 76702400 LPG 128-20 CO2Modular cylinder includedin Annex I).

In this case, the system consists of only one cylinder, which contains the extinguishingagent, and the valve incorporates all actuation and discharge release systems. Thevalve makes use of the pressure contained in the cylinder to open. Normally fittedwith manual and electrical solenoid valve actuation system. Pneumatic actuation isalso possible for special applications.

There are self-contained cylinder models of 5, 134, 268, 402 and 67 litres fitted withLPG 128-20 valve (technical data sheet Nr. 140). The valve incorporate micro leakageproof actuation devices and a safety disk to prevent cylinder over pressurisation.

5 I N S T A L L A T I O N .

During system Installation it is recommended to make continual use of drawings enclosedwith component delivery. This will help to understand the system better.

As an example Annex I consists of standard drawings showing different models of carbondioxide (CO2) cylinder banks. In these the arrangement of cylinder bank, connection of

single release system and arrangement of standard support systems can be seen. Thesedrawings are enclosed as an example, however for installations accompanied by specificdrawings, these will prevail.

Prior to starting installation check the drawings and lists of materials to ensure that allcomponents have been delivered. Check that the components are not damaged. Anydefective components should be replaced. Check the position of the cylinders and lengths ofpipes in the drawings. Check that there are no fixed barriers, which may requiremodification of cylinder location, brackets and lengths of pipes. The Project EngineeringDepartment should be informed of any deviation from the drawings.

Prior to starting installation check the cylinder bank location (generally indicated in thedrawings). The location advisable for the cylinder bank would be a room as near as possible

but outside of hazard protected, big enough to house the equipment and to facilitateInstallation and maintenance operations. The equipment should not be exposed to severeweather conditions, direct contact with flame, excessive humidity and safe fromunauthorised handling and mechanical or chemical damage.

Required material for equipment installation:

- Teflon tape, 04 mm thread sealing compound - Drills(for building materials)

- White Vaseline - Hacksaw

- Set of fixed wrenches (6 to 22 mm)- Pipe cutter suitable for cutting

copper pipes- Monkey wrench - Ladders, scaffolds

- Clamps, pliers - Flexometer

- Set of Allen keys - Magnetic level

- Set of Phillips and flat head screwdrivers - Electric Tester

- Electric hand hammer / drill - Rounded Spanners (See note)

- M.12 Plugs of quality suitable for the fixing surface.

Note: A minimum of two operators is required to perform equipment installation.

5.1 MECHANICAL / PNEUMATIC INSTALLATION.

LPG carbon dioxide (CO2)centralised systems are divided into 4 systems:

1. Support system.

2. Storage system.

3.

Release system.4. Distribution system.

Installation operations and components for each system are described as follows. Thesequence in which components are described is at the same time, the order in which theyshould be installed.

5 . 1 . 1

Su p p o r t s y s t e m .

Description:

A metallic structure consisting of a frame (bracket) which supports the cylinder block andthe manifold.

The brackets are just fixed to the wall (no support columns) or are provided with verticalsupport columns. There is also an specific model for the systems with the weighing device.

Installation:

The following points should be considered at the time of performing the installation:

- Thoroughly clean the area where the system is going to be located. Check thedrawing measurements to ensure that the cylinder bank fits perfectly inlocation chosen.

- Verify that the floor where the system is going to be mounted is as flat aspossible.

- The wall where the bracket is going to be fixed (if necessary) must be solid

and in perpendicular position from the floor (avoid partition walls, Pladur orsimilar).

- If the bracket has to be fixed to a partition wall, plates to support the bracketon the opposite face of the partition wall should be used in accordance withdrawing:

The Installation of the bracket and the position of manifold depend on whether the bracketis fitted with vertical side support column or not and whether connection to pipe system is

vertical or to the side.

LPG supplies the cylinder fixing brackets together with equipment. Among them, three typesmay be distinguished:

a) Brackets provided with vertical support column.

b) Brackets with no vertical support column.

c) Brackets for self-contained cylinders.

Within each of these types there are different models, which comply with use requirementsof system supplied. This manual describes the characteristics of each of the types butwithout entering into Installation details for each of the models consisting of these. Toperform installation "in situ" drawings supplied together with equipment should be used andinstructions contained in this manual should be taken into account.

As an example, Annex I contains standard drawings showing brackets described above.

The characteristic of this type of bracket is that the vertical support columns are includedwhich may be fixed directly to wall and floor. This configuration gives stability and rigidity tothe cylinder bank assembly.

The following models are included within this family:

a) Single row bracket: All bank cylinders are aligned in a single row and the weight

of the manifold pipe rests on the bracket structure.b) Double row bracket:All bank cylinders are aligned in two parallel rows and the

weight of the manifold pipe rests on the bracket structure.

c) Bracket with weighing device:The cylinders can be aligned in a single row or intwo parallel rows. The cylinders are supported on the bracket structure.

Enlarged drawings of different models of brackets are enclosed in Annex I. Refer to them foridentification of each element described in the written procedure.

The following points should be considered when faced with the job of Installation one ofthese brackets:

1. A drawing of the mounted system is delivered with every equipment supplied and atleast a standard enlarged drawing with the bracket. It is essential to understand thesedrawings thoroughly prior to start Installation.

2. Drawings supplied indicate cylinder bank measurements. Perform an initial check toensure that the structure fits perfectly in the area chosen.

3.

Clean the area where the bracket is going to be installed.4. In accordance with system drawings perform a bracket pre-Installation on the floor. It

is not necessary to mount the complete bracket. It is sufficient to mount those structurecomponents closest to the wall.

5. When performing pre-Installation it is necessary to take into account the fixing systemof the different structure parts. Vertical support columns incorporate some welded orscrewed lugs on their sides. The purpose of these lugs is to hold the cylinder bankcrosspieces1. Correct connection between the vertical support column and thecrosspiece is described in the following figure.

6. The manifold seats2are mounted directly onto the vertical support columns. Dependingon the cylinder bank model, manifold seats may differ according to their position on thecylinder bank. It is essential to consult the system drawing to determine the exactposition of each.

7. Once pre-Installation is performed, put them in their final position taking intoconsideration the required distance for connection between the manifold pipe and thenozzle pipe system. When accurate location is found, tighten all screws, which ensurethe connections between support vertical columns and the crosspieces to make thestructure rigid. Align the different structure components vertically and horizontally so asnot to distort the shape or position of bracket.

8. Place the two bank cylinders which are farthest apart from each other onto brackets andtighten. For cylinder banks consisting of 8 or less cylinders, one of them may be thepilot cylinder. Align the valve outlet as indicated in system drawing.

9. Locate the manifold pipe3onto its seats and make level fitting the height of each one ofthem. Warning: the system is not fastened onto any fixed part in the buildingyet.Take the necessary precautions to prevent the assembly from falling over.

10. Place the manifold check valves for each of the cylinders presented. It is not necessaryto perform final installation of these parts.

11. Place discharge hoses between cylinder valves and the check valves. It is not necessaryto perform final installation of hoses.

12. Find the best location for the manifold with respect to the location and position of thedischarge hose. Compare with the cylinder bank drawings. Once proper location ofmanifold is found, that is final position of bracket. Independently of the representationof the draws, it is possible that for a perfect adjustment all the cylinders must be turneda little on themselves by rows. All of them must be turned in the same sense.

13. Check the vertical and horizontal level of the cylinders and mounted parts of thebrackets prior to marking anchoring points on the floor and wall. It is possible to drilltaking as a guide those fixing holes on the brackets. Fix bracket into its final position.High-power chemical or mechanical fixing plugs should be used for floor and wall fixing.Do not use plastic plugs.

14. Mount the remainder of bank cylinders onto the bracket and finish the metallicstructure. It is very important that all cylinders are in the same direction and verticallylevelled so as to prevent problems when installing discharge hoses.

5.1.2.2 Installation of brackets for self-contained cylinders.

These brackets are designed for holding one single cylinder. Installation is very simple. Justplace the bracket against the wall to the height indicated in the drawings supplied. Fix thecylinder taking care that the pressure gauge and manual actuation system are easily visibleand accessible. Once the cylinder is installed connect to the nozzle line together with thedischarge hose supplied.

Annex I includes different Installation systems depending on the self-contained cylindervolume. Refer to them to identify each one of the elements described in procedure.

High power chemical or metallic fixing plugs should be used for fixing bracket onto the wall.Do not use plastic plugs. If the wall is not strong enough carry out Installation as describedin 5.1.1.

It is very important never to install nozzles directly at cylinder outlet for tworeasons. Firstly, if nozzle is installed directly on valve outlet there are many possibilities that

the nozzle will be at a person's height. In case of cylinder discharge (accidental orotherwise) pressure released could cause serious injuries to personnel who might besomewhere near the cylinder.

Secondly, the strength of reaction produced by the discharge is always generated at the gasoutlet. If coupled to the cylinder outlet, the result could be that the wall bracket could beviolently pulled out.

The relief valve device on the head cap (made up of parts 20,21, 22 and 23) preventsaccidental cylinder discharge caused by micro leakage of pressure produced by somerelease devices.

The safety disk (10) is set ready to burst and release the internal cylinder pressure whenthe pressure reaches values slightly inferior to the cylinder hydraulic pressure. This deviceprevents an excessive rise in pressure (for example, due to over heating) that may cause

the assembly to explode.The burst disk (19) allows actuation of manual and pneumatic release devices. When thisdisk bursts by means of the release system connected to it, the valve opens. Its setpressure does not allow bursting caused by cylinder over pressure.

To prevent uncontrolled accidental discharges during installation, maintenance operations orhandling of the valve, remove the head cap (8) and place the cap (25) on the valve outlet.This simple operation prevents risks; in case of accidental release the orifice (33) will directgas from the cylinder to the atmosphere in a controlled way, thus preventing valveactuation. The safety disk cap (9) incorporates orifices, which allow controlled gas dischargein case over pressurisation bursts the safety disk (10).

Installation:

The valve is supplied mounted onto the cylinder. Do not try to disassemble any of theaccessories that come incorporated. The Installation parts attached to the valve (dischargehose and release devices) should be performed later, following the order they are described.

Manual Lever Release Actuation

This actuation system is used for pilot cylinders and self-contained cylinders.

LPG Valves make use of the cylinder internal pressure for opening.The only way to activate valve is by making the piston move downwards (1).

When valve is at rest, pressure is retained by the sealing element (2) and the release disk(3).

When the release is activated manually by pulling the lever (4) backwards and the hammerpiston (5) is pushed downwards, this will cause the release disk (3) to burst. At thatmoment the pressure retained by the release disk is released and directed over the piston(1). Given that the ratio of surface area between the piston (1) and the sealing element (2)is 3:1, the piston moves downwards and opens the valve.

LPG Valves make use of cylinder internal pressure for opening.

The only way to activate valve is by making the piston move downwards (1).

When valve is at rest, pressure is retained by the sealing element (2) and the piston (4) in

the solenoid valve (5).When solenoid valve (5) is energised, the piston (4) moves backwards allowing freepassage of pressure. This pressure is directed through the internal passage (3) over thepiston (1). Given that the ratio of surface area between the piston (1) and the sealingelement (2) is 3:1, the piston moves downwards and opens the valve.

The design of the valve allows the assembly/disassembly of the heads when the cylindersare filled and pressurized.

The head (pneumatic or manual lever) should be removed in order to avoid accidentaldischarges during the installation or maintenance operations and whenever there is somekind of manipulation on the valve.

Installation:

The valve is supplied assembled on the cylinder. None of its components (with the exceptionof the release heads) should be dismantled. The assembly of the devices on the valve(discharge hose and release devices) will be done later following the same order as shownin its description.

When the cylinder is used as auxiliarycylinder, there is a pneumatic head of2 or 3 ways with pneumatic connectionas shown in the drawing.

When the cylinder is used as modular, there isa lever head on the valve which allows themanual activation of the valve as shown in thedrawing. For special cases of combinedrelease, there is also a model of lever head

with connection for pneumatic release.

Fig. 5.2.3.1.Pressure Gauge 0-160 bar

Installation:

The pressure gauge is supplied factory mounted on the pilot cylinder valve. If for anyreason you have to disassemble (for example, to remove solenoid valve), remove itsprotector cap by unscrewing by hand. Using a fixed wrench, loosen the fixing nut containedin the pressure gauge and valve body and remove the pressure gauge by unscrewing byhand.

Prior to starting Installation of the pressure gauge on the valve, check for the O ring sealand a fixing nut. Prior to connecting the pressure gauge, move the nut against the O ring

to unscrew the first thread. Begin to thread the pressure gauge into its coupling by turningby hand, at the same time with the help of a fixed wrench tighten the fixing nut. In thisway, the fixing nut pushes the O ring preventing its being ejected by cylinder pressure.

If during this operation, the fixing nut touches the valve body (it is detected becauseflattening of the O ring may not be filled) loosen the fixing nut a little and continue.

When gauge reaches the bottom and you observe that O ring is properly fitted, check theposition of the lens and the pressure indicating needle. If the lens is not in its normalreading position, by holding the fixing nut with a fixed wrench so that it will not move,rotate the gauge until a suitable position is found. Once in position, tighten the fixing nutagainst the valve body so as to fix its position.

Check with soapy water for possible leakage for 10 minutes prior to completion of the

operation.

Pressure switch rated at 25 bar. Consists of a fill control element for the agent contained inthe cylinder as it allows control of pressure drop produced by leakage or discharge bymeans of an electric signal.

Fig. 5.2.4.1.Pressure switch

Installation:

Mount the pressure switch into its housing on the opposite side to the valve gauge.Prior to this, remove the factory installed cap.

Slowly hand thread the pressure switch (check that sealing 0 ring is present) ontothe coupling until reaching the small bleed housed inside valve. At that moment aslight pressure release will be heard. Loosen turn until pressure release stopsand then tighten quickly so as to prevent gas leakage. The threaded union does notrequire a sealing element as it is sealed by means of the O ring.

Tighten the pressure switch using a fixed wrench but do not force the joint.

Check for leakage for 10 minutes with soapy water prior to considering theoperation complete.

If when installing the pressure switch, the released pressure ejects the O ring

seal, push slightly the pressure switch filter as shown in the drawing.

Carry out the electrical connection when installation is complete. Specified in this manual in

Description:

Weight control devices are designed to allow continuous control of cylinder charge condition.The equipment gives an alarm signal when there is a loss of more than 5% or 10% of initialcharge, in accordance with ISO, CEPREVEN and NFPA standards.

Fig. 5.2.17.1. Electronic weighing device system

Systems are provided with a central unit that can be connected to the fire stationas well as with several weight control units, one for each cylinder to be controlled.Weight control units formed by a load cell which allows detection of leakages with aresolution of 1 kg. Load cell incorporates an extensometer gage. All weight controlunits are connected to central unit, by means of a BUS.

This equipment allows you to check from central unit real charge, nominal charge, actualextinguishing charge, minimum permissible weight and state of each weight control unit.

Each central unit is designed to control a maximum of 31 weight control units. More centralunits shall be supplied for those installations requiring more weight control units. Eachcentral unit has to be considered as totally independent equipment.

The equipment described has been developed to carry out cylinder charge control. Thusallowing to know the actual charge weight contained. Central unit consults in a continuousmanner condition of each cylinder and receives the information from weight control unitmechanically associated to it. For this purpose each unit is assigned an internal address.Address assignment is carried out at equipment commissioning.

In the event of failure of power supply the equipment keeps configuration in its memory butwill not carry out weight control. The system will keep operating without any need ofsupervision at the moment power supply is restored.

Description:

Mechanical system for monitoring the level of gas in each of the cylinders which are part ofa bank of cylinders. The way it works is based on the weight reduction of a cylinder whenthere is a gas loss. This system does not consider the real weight of the cylinder.

Fig. 5.2.18.1.Mechanical weighing device system

Each cylinder is hanging from a mechanical control module (1). A 10% loss is enough forthe module to issue an optical signal showing the failure (by the falling of the metallic coverof the module). If necessary, the system can be supplied with a photocell (2) and a mirror(3) allowing the monitor of the system by means of external devices (control panel) andreleasing other alarm systems both optical and acoustic. One single photocell allowsmonitoring banks of up to 10 meters length.

The installation and commissioning of this weighing device system is very easy and allowsmanual adjustments to modify the sensitivity of the control modules.

Upon order confirmation and coming from manufacturer it is possible to supply mechanicalweighing modules for different kinds of cylinders and levels of weighing lost.

Installation:

With each mechanical weighing device instructions for assembly and commissioning arehanded out.

5.3 RELEASE SYSTEM.

This is the system, which allows command of gas discharge contained in the cylinders. Thecarbon dioxide (CO2)standard release system is pneumatically operated. Annex 1 containsas an example, drawings of the following carbon dioxide (CO2)release systems:

Sketch for discharge and release system: carbon dioxide (CO2)cylinder bank providedwith master cylinder (cylinder banks of 8 or less cylinders of 402 or 67 litres N.50040676).

Sketch for discharge and release system: carbon dioxide (CO2)cylinder bank providedwith pilot cylinder (up to 40 cylinders of 402 or 67 litres N. 50090673).

The drawings mentioned above show the connection of release systems of differentcomplexity. However, these drawings are included as examples.Therefore, for installationsprovided with specific drawings, such drawings will prevail.

The pneumatic release consists of one master cylinder or one or two pilot cylinders, with apilot valve incorporated into each. The pilot valve combines different release devices, suchas manual release devices, electric actuation by means of solenoid valve, which once

activated carries out the opening of the slave cylinder valves. This is a flexible system,which may incorporate more than one pilot cylinder and command release from severalcylinder banks simultaneously.

Components which may be included into a carbon dioxide (CO2) release system and theInstallation of each are described as follows. Installation is performed in the order the partsare described.
