All the information in this manual must be read and understood before system installation ormaintenance.Pay particular attention to the manual sections with note WARNING:the non observance of that notes can cause damage to the persons and/or equipments.



1. PURPOSE

The purpose of this manual is to provide the installer with the necessary information required forcorrect assembly of the systems and special apparatus, and furthermore, information regarding theinspections to be carried out and tests to be executed on the systems before being made available foruse.This manual has also the scope to give the contractor or user the information necessary for theinstallation, preliminary and final verification, before the start-up of the system or of the specialequipment supplied, and furthermore, information regarding the system maintenance.

As this manual is not specific for type of system or equipment supplied, we haveconsidered the common parts, recognizable in similar situations, with reference to other documents inwhich the characteristics of the components used are clearly described, as well as all the otherinformation necessary for the installation and verification.



2. HEALTH AND SAFETY

2.1. SAFETY REQUIREMENTS

Safety rules to be observed during the assembling and maintenance are those indicated byregulations in force, all further regulations prescribed by the purchaser or by the Authorities havingjurisdiction and also, where applicable, European safety directive (Machinery directive 37/98,PED97/23, ATEX 94/9, EMC 89/336, low voltage 73/23).

2.2. GAS TOXICITY

The supplied fire - fighting system uses the carbon dioxide as an extinguishing agent. This normallyappears in the form of odourless and colourless gas which, through rapid and severe expansion, willproduce both a fall in temperature (because it is capable of evaporating quickly without leavingresidue) and a reduction in the percentage of oxygen below the values which allow combustion.Carbon dioxide insulates more than air and does not corrode or damage any material.Carbon dioxide, which remains within a location, can be easily removed by airing or by mechanicalventilation because it is heavier than simple air.

Due to the fact that a man can not breathe without difficulty in a room where carbon dioxide is presentin any concentration higher than 3.5%, it is important to be extremely careful on entering a room inwhich even a small amount of gas has been released. Therefore, the use of breathing apparatus isvery important.If a person should show symptoms of carbon dioxide suffocation, it is necessary to take that personout of the location immediately, then artificial respiration should be administered, like it would be in thecase of drowning, oxygen has to be given in order to achieve revival. Carbon dioxide which remainswithin a location can be easily removed by airing or by mechanical ventilation because it is heavierthan air.

These operations should be carried out in the presence of a doctor.

2.3. CO2 CYLINDERS DANGER

Pressurized (charged) cylinders are extremely hazardous and, if not handled properly, are capable ofviolent discharge. This may result in serious bodily injury or property damage ; always handle carbondioxide cylinders with care. Cylinders are factory equipped with a protection cap. This device is asafety feature and provide protection during handling.Do not move or handle a carbon dioxide cylinder unless the protection cap and the valve safety pinare installed. For cylinder installation and removing see the relative paragraphs.

2.4. ELECTRIC SAFETY

The supplied fire - fighting system has a power supply for electrical equipments.During any operation of assembly and maintenance for any electrical equipments, the system isolationfrom power supply is mandatory.



3. GENERAL NOTES REGARDING CARBON DIOXIDE

3.1. CO2 SYSTEMS FIELD APPLICATION

Carbon dioxide can be used to extinguish fires caused by:

- inflammable liquids (class B fires) and materials reacting in a similar way to fire exposures, i.e. givesurface fires

- inflammable gases (C class fires); in that case you need to check that after the extinction there is noformation of explosive atmosphere because of unburnt gas leaks

- devices and electrical systems under tension

- wood, paper, cloth, etc. (A class fires); normally in these cases a great quantity of CO2 and a longpermanence of the same in atmosphere are necessary to allow for the slow decreasing of ambienttemperature and of embers

With CO2 there is no extinction of fires caused by:

- products containing the oxygen necessary for combustion- metals and chemical products reacting to CO2, such as alkaline metals and titanium

Extinguishing action of carbon dioxide is based upon the reduction of the concentration of oxygen inthe air down to a level preventing combustion, at the same time the cooling caused by carbon dioxidedischarge contributes, as a secondary effect, to extinction.

After discharging it may be necessary to keep carbon dioxide in the environment even once the firehas been extinguished, in order to allow for the various objects to cool down and avoid new firesstarting.

The carbon dioxide at environmental conditions is at gaseous state, consequently it is used into closedrooms where the gas loss is moderate. It can be, however, used for the protection of open areas, byadopting proper techniques.



3.2. CARBON DIOXIDE NOMENCLATURE

The carbon dioxide is colourless, odourless, and electrically no-conductive, the density of which ishigher than 50% the one of the air.

- Chemical formula: CO2

- Molecular weight: 44

- Volume mass at 0°C and at 0,101 MPa (abs.): 1,98 kg/m3

- Density relevant to the air: about 1,5

- Steam tension at 21°C : 58,6 bar abs.

- Triple point:Temperature: -55,6 °CPressure: 5,17 bar abs.

4. CO2 SYSTEMS GENERAL DESCRIPTION

The following systems described were installed for fire - fighting protection of areas which haveelectrical apparatus and/or live wires, by means of high pressure type carbon dioxide systems.The system, of the fixed type, is made up of piping normally empty, connected to a set of CO2 storagecylinders.Nozzles of the open type, distributed and orientated in accordance with the applicable standardsinstalled onto the piping, release the gas within the protected area to contain and extinguish the fire.The intervention of the system is activated automatically by means of the fire detection system whichwill power up the electric controls located on the pilot cylinder, and/or manually, on site, by means ofsuitable handle controls acting exclusively on the pilot cylinder of the CO2 storage set.The intervention of the pilot cylinder will control the opening of all other slave cylinders.The release of gas will activate, by means of a pressure device, the alarm signals, which will then bedisplayed as the intervention on the control panel.

4.1. CO2 CYLINDERS UNIT

The fire is extinguished thanks to the release within the protected areas of a calculated quantity ofcarbon dioxide stored on cylinders placed in a safe position, on a suitable rack.The quantity of carbon dioxide is calculated in accordance with Regulation number 12 of TheAmerican National Fire Protection Association (NFPA) and based upon the specific requirement of theprojectThe cylinders are made of special carbon steel and tested up to 250 Kg. / cm2.Every cylinder is equipped with a special quick release valve and siphon, and complete with a safetydisk against over-pressure.The bursting pressure of the safety disk is equal to 250 bar.Each cylinder is further provided with a mechanical weighing device, which indicates that the contentsof the cylinders are max. 10% below their nominal charge.All the cylinders are connected to a manifold by means of flexible hoses. On the connections of themanifold, suitable check valves are installed.These allow the performance of the system even in the case of one or more disconnected cylindersfor maintenance purposes.For cylinder unit controlled with pneumatic devices, the pilot cylinder check valves are supplied with alateral coupling, for the connection of the pressurisation circuit of the pneumatic operator whichcontrols the intervention of the system of levers of all the slave cylinders.

4.2. DISTRIBUTION NETWORK

The distribution network is made of piping of calculated thickness to cope with the pressure of thegas, connected by means of fittings junctions.Discharge nozzles, supplied with purposely calculated drills, are installed onto the piping in the idealposition.The quantity and the location of these nozzles are established according to the type of protection, thedischarge time and the characteristics of the area and/or the protected equipment.

4.3. FIRE DETECTION AND FIRE ALARM SYSTEM

In the protected areas, for quick signalling and a subsequent immediate intervention, fire detectionsystems with smoke, gas or heat detectors are installed.The systems are controlled by main control panel located in the FIRE FIGHTING ROOM.In the field, near particular zone specified in the project, are placed several fire alarm devices ashorns and flashing lamps to warning the personnel to evacuate immediately the area; moreover othersdevices as push buttons, are placed for a manual alarm call, manual discharge or shutdown function.Often, in proximity of the protected areas accesses, CO2 system status panels are installed to warningthe personnel related to the CO2 system operations (ex. System “Auto” , “Inhibited” , “CO2 Discharge”).For the description of these systems see the relevant manual.



4.4. SYSTEM OPERATION

The automatic intervention of the system is activated by a detection system which will actuate bymeans of the electrical control the pilot cylinders and consequently the beginning of the gas discharge(the start discharge is normally delayed of 30 seconds).Part of the gas, by means of the pneumatic circuit of the check valve, will pressurise the pneumaticpistons; these ones, by means of their levers pull the opening control bars of all the interestedcylinders.The actuation manual control by means of a push button will follow the above described logic ofintervention.To signal the intervention of the system, on the discharge pipe is installed a pressure device (normallya pressure switch with manual reset), connected to the system alarm panel.

For the emergency manual mechanical control, it is necessary to proceed as follows:

- act on the pull handle on the cylinder rack, causing the immediately intervention and the gasdischarge.

WARNING: Before actuate the intervention devices, be sure that nobody is in the protectedzone or it the nearby or communicant zones .The gas discharge is extremely dangerous for the people which should inhale it or for therescuers if not provided with breathing apparatus.CARBON DIOXIDE GAS CAN CAUSE INJURY OR DEATH.

h) Connect the unit to the detection and control system electrically, and it will have to be and remainin a defused position.



DISTRIBUTION NETWORK

Proceed in the following way:

i) Preparation of the non prefabricated pipes and supports including cleaning and execution of theprotective coating according to specifications.

j) Installation of necessary supports.

k) Installation of pipes and tightening of the connections and supporting components.

l) Installation of special equipment while taking into account the indications described in theChapters 6.5 and 6.6 here below described for the execution of preliminary tests hampering theinstallation itself. m) Connection to the feeding unit. REMARK: all the threaded connections must be complete with dedicated sealing product asLoxeal 18-10 or equivalent, other materials as hemp or Teflon are not acceptable.

7.5. ASSEMBLING TOLERANCES AND CONTROLS

It is not necessary to carry out particular checks during the assembling works of the system or of theconsidered equipment. The dimensions indicated in the drawings will be considered with an average tolerance degree, asnormally done in mechanical constructions executed for plumbers and carpenters works. Dimensions to be observed are mainly those ones concerning the positioning of supports and specialcomponents. Particular care will be taken for the erection of the nozzles and of the system instruments. REMARK: the piping system shall be installed in accordance with the approved system plans and thelatest version of SANCO CO2 flow calculation program; any deviation from the system plans or flowcalculation program must be approved by SANCO and a system flow calculation performed to confirmthe acceptability of the changes.

7.6. FINAL OPERATIONS

At the end of each erection work, the following operations will be carried out according to the differentsystem sections. a) Cylinders units:• The electric system of whole group will be submit to test operations together with ones relating tosignaling and control system, described in the relevant manual. b) Distribution net:• Carry out a pneumatic test on the whole circuit, by pressurizing with compressed air or nitrogen, inorder to verify the tightness of the couplings and the integrity of the components. The test pressure willbe about 3 bar. The period of the test will be at least 10’. Longer periods will be expressly indicated onthe project documents.• A test pressure decrease within 20% after 10’ will be acceptable. During the test possible leakage will be verified. They will have to be eliminated and the test will haveto be repeated till the relevant result will be positive. The cut-off valves must be closed and instead of the nozzles, caps will be assembled. The verification can be carried out in different system section, in case the system is particularlyextended or in case some particular considerations are necessary.



• At the end of the pneumatic test, removing all the caps and carry out the blowing of the piping bymeans of inlet of compressed air or nitrogen.The flow must have the direction from control unit to nozzles. Clean any obstructed connection and all the dirty traps at the end of the pipe line, even if partially,before reinstalling the nozzles. At the end of the operation install the nozzles, taking care that all the couplings are tightened. REMARK: the CO2 system include a variety of discharge nozzles, each designed for a specificapplication or flow rate: all nozzles have discharge orifices drilled to suit the specific nozzle locationand discharge flow requirements (see the stamped values on each nozzle). When installing nozzles, it is imperative that the correct nozzle be installed in its appropriate locationwithin the system discharge piping network (refer to the CO2 piping layout drawing to find the exactlylocation of each nozzle): the not respect of such indications involve a not corrected dischargeinside the specified protected area.

c) Whole system:• Check that the installation is complete and that the nozzles and the special components have beencorrectly placed.

Issue test reports indicating that the final operations have been carried out. The documents should becomplete with the registered data, the date and the name of the persons who took part in theoperations.

7.7. FINAL CHECK

a) Cylinders units :• Verify that the structures are well fixed both among them and to the floor, the counterweight of

weighing devices are locked between the relevant nuts and lock nuts, the pneumatic circuits areconnected and couplings well closed.

• Verify that all electric equipment are correctly connected, but that the relevant control panels arenot energized.

For all operations of test of the control and signaling circuits, refer to the relevant manuals.

b) Distribution system• Verify that the pipes are completely assembled and connected and supports are well fixed on the

structures, walls and ceilings; the discharge nozzles are installed in its appropriate locations andsupplied with protecting screen.

c) Protected area :• Verify that all pipes passing through walls and ceilings are sealed; all openings, that are not

considered in the system calculations, are sealed or supplied with automatic closing devices; theexistence of all warning intervention devices to evacuate the protected area.

d) Whole system• Carry out the test operations as below described, in order to verify, where possible, the correct

working of the equipment before the possible “START UP”.



8. TEST PROCEDURE At the end of the control operations previously described, proceed with the hereunder listed testoperations. 8.1. FUNCTIONAL TEST

Carry out the functional test of the different components in order to make sure of their working, withoutcausing the intervention of the extinguishing systems but only the activation of signaling and controldevices, connected to the different components or controlled by them. • Test the pressure switch pushing in the internal piston (see relevant manual for others pressure devices as pressure transmitters). • Test the electromechanical controls with lever extension of pilot cylinder valves disconnected

from the same valves, in order to verify their activation by means of an electric impulse controlledby the relevant control panel.

• Check the intervention of the weighing switches, by putting up cylinders lightly, till they will operate.

• Check the correct function of other devices if any (cut-off valve limit switches, selector switches,etc.)

8.2. OPERATIONAL TEST

As per NFPA12 requirements, each carbon dioxide system must be tested with full gas discharge inorder to make sure that the project characteristics are observed, causing the intervention of thesystems with the distribution of the extinguishing agent in the considered area. For this test we suggest to contact a Fire Fighting Company or equivalent agency, agreed withauthority having jurisdiction. The execution of the test must be entrusted to trained personnel, who are also provided with allnecessary safety equipment.

All CO2 systems testing should successfully accomplish the following:

• Check the integrity of the piping distribution including cylinders rack, supports and anchors.• Verify detector operation.• Verify audible and/or visual alarm operation.• Verify manual release operation.• Verify that all interlock and shutdown functions operate and occur at the appropriate time in the

system discharge sequence.• Actuation sequence conforms to the intended design and pre-discharge time delays (if provided),

operates correctly and with the correct time delay period.• All pressure operated devices function as intended at the correct point in the firing sequence.• All safety and warning features are in place and operate satisfactorily.• Design concentration is attained within the appropriate time in accordance with NFPA 12.• Designed concentration levels are attained and remain in the hazard area for the period of time

specified. The ability to reach and maintain concentration levels is STRICTLY dependent upon theconstruction of the enclosure and measures taken to prevent agent loss. Total flood systemsperform best when agent loss due leakage from the enclosure is held a minimum.



REMARK: performing a “Room Integrity Fan Test” is strongly recommended prior to conducting adischarge test; this test is “non-destructive” and will help to find the points of possible hazard leakagethat can be sealed and secured before the discharge test is performed.

In order to carry out the “OPERATING TESTS”, it will be necessary to complete the assembly ofextension pilot cylinder levers and the removal of all safety pins of cylinder valves.

At the end of the test, a final test report has to be issued, signed by all persons representing the firmcharged with the installation, the purchaser / final customer.On the report all data relevant to the test and possible remarks will have to be indicated.



9. SYSTEM OPERATIONS

9.1. START-UP PROCEDURES

When the systems are completely tested, as indicate in the above chapters, the following controloperations must be executed:

a) Cylinder battery, please check:

• that the structures are properly fixed, one to the other and to the floor;• that the counter weights of the weighing devices are blocked within the relevant nuts and bolts;• the pneumatic circuits are properly connected and the fittings properly sealed• the electric circuit are connected to the equipment and to the signalling and control system• the safety pins are positioned in the valves• set and rearm the controls without positioning the lever extensions• with the cylinder lever extensions disconnected from the same valve, test the electromechanical

control with the actuation by means of electrical impulse controlled by the relevant panel• lift slowly the cylinder to verify the action of the weighing device and the click of the related limit

switch• actuate by means of the relevant internal piston the “system intervened” pressure switch (for this

operation the pressure switch will be disconnected from their coupling). For others pressuredevices as pressure transmitters see the relevant manual.

b) Distribution net, please check:

• The piping are completely assembled, connected and the supports are properly fixed on thestructures, walls and ceilings;

• The CO2 nozzles are installed

c) Protected area, please check:

• All passages of the piping through walls and ceilings are well sealed;• All the openings, non considered in system calculation are sealed or provided with automatic

closing devices at the system intervention;• All the pre-alert devices for the evacuation of the protected area are correctly installed and visible

REMARKS: - start up of the CO2 system can be effected only if the detection system hasbeen inspected and tested as described in the relevant manual.- to make the system working it is necessary to authorize the “AUTOMATIC” functionin the control panel. At the end of all the above described operations, verify that thecontrol panel is fully functioning and that it does not signal any fault or alarm condition.

WARNING: After system installation and start-up procedure remove the safety pinsfrom the cylinders and open cut-off valves.

NOW THE SYSTEM IS READY TO BE “STARTED”



9.2. NORMAL OPERATIONS

Once the system here described is working in accordance with all procedures described in theprevious chapters and is kept in perfect condition always in accordance with the maintenanceinstructions described in the proper chapters of this manual, is in a position of operate in anindependent way on condition that all required values concerning pressure and flow are respected.At the same time, also detection and control system must be on operating condition, as indicated inthe relevant manual.Particular care must be taken as for new structures or storage conditions of the goods in the protectedhazard do not imply the good working of the same, or modify the characteristics of the protectedhazard, making the system not suitable.

9.3. SHUT DOWN PROCEDURE

WARNING The system should be placed out of service only for repairs. The work to be done must becompleted in a manner to minimise the time that the system must be out of service. All hazardousactivities in the effected area shall be terminated until the system is placed back in service. Anysystem impairment shall be co-ordinated with the owner, local authority having jurisdiction and otherrelated parties. Place a roving fire patrol in the area covered by the system until the system is back inservice.Prior to turning off any valves or activating any alarms, notify local security guards and/or central alarmstation (if used) so that a false alarm will not be signalled and result in a local fire departmentresponse.After the precautions indicated above and before any disassembly of the parts of the system, followthe instructions listed below:

• Close cut-off valve;• Disconnect the pneumatic line which controls the pneumatic operators that open the cylinders from

the discharge collector;• Disconnect the opening control levers of the valves mounted on the pilot cylinder;• Put, in the appropriate drills, the shear pins which are fixed to the valves body by a small wire rope

inhibiting the function of the valve itself;• Put “SYSTEM OUT OF ORDER” warning notices into positions where they can be well noticed;

REPAIRS: When necessary, owing to intervention or damages occurred, please execute repairs andmind to use same material as the original ones and following in this way the initial project.Any difference need to be approved in writing, by SANCO or by the local Authority having jurisdiction.

Repairs must be carried out in accordance with the guidelines of the operations described in theprevious chapters.

RESTART: See Section 8.1 of this Manual “START-UP PROCEDURES” for all operationsconcerning the operative restoration of the system. At the end of those operations which have requiredthe replacement of some parts, the components which are normally stored as spare parts and whichhave been used for repairs, should be replaced; the new components should be identical to thosewhich have been used for repairs or of an equivalent type, authorised by the Manufacturer.



9.4 TROUBLESHOOTING

Due to the fact that the CO2 components do not function continuously, they manifest a low degree ofwear. Therefore, with normal use and preventive maintenance carried out, protecting against corrosionand eventual mechanical damage caused by accidental impacts, the system should be reliable for along time.

WARNING CO2 cylinders should never be handled or moved without the protective safety capsecurely in place. DO NOT remove this cap until the cylinders have been installed in to their rack.

11.1. REMOVAL

• Temporarily put the system out of order, acting on the control and signalling panel, according to theprocedures described in the relevant manual

• Verify that all precautions have been taken, in order to act in complete safety condition on thecylinders batteries, included the warning by means of a proper notice indicating ‘SYSTEM OUT OFORDER’.

• Disarm the emergency control systems, where existing and the electromechanical controls of thecylinders and on the release cabinet.

• Draw off the valve lever from the cylinder valve.• Disconnect the discharge hose from the cylinder.• Disconnect the cylinder from the rack following backwards the indications contained in the chapter

concerning the installation of the same.• Send the cylinder to the supplier for relevant recharging and checking, it will have to be sent

complete with the relevant protections (cap, seal, etc.)

11.2. RECHARGING

• Carry out the weighing of the cylinder for the definition of the quantity necessary for the restoring ofthe discharge conditions.

• Verify if it is a restoration, the seal of the valve by means of proper liquids or sprays for searchingof little leakage. In case some leakage could be found out, completely discharge the cylinder, afterhaving blocked it firmly and provide for maintenance or replacement of the valve with another of thesame type.

• Place the cylinder on a balance, fixing it and verifying its stability.• Connect the valve, outlet site, to the hose of the recharging system, provided with the shut-off and

vent valves.• Steadily tighten the connections.• Open the cylinder valve, and verify that the shut-off and vent valves are closed. Verify the seals, if

they works with cylinders partially charged.• Open the charging valve and transfer the extinguishing agent in the cylinder. When the desired

weight is reached, close the charging valves and the cylinder valve. Open the vent valve and verifythat there are no leakage from the circuit. If it is necessary close again and verify the closing of theother valves

Disconnect the hose from the cylinder and the same one from the balance. Take note of the date ofthe recharging on a proper register, included the possible maintenance carried out. Verify the seal ofthe valve and apply the transport seals and the proper protections

GENERAL The unit is manufactured, checked and supplied in accordance with our published specification, and when installed and used in normal or prescribed applications, with the lid in place and within the parameters set for mechanical and electrical performance, will not cause danger or hazard to life or limb.

HEALTH AND SAFETY AT WORK ACT 1974 WARNINGS 1. THE USERS ATTENTION IS DRAWN TO THE FACT THAT, WHEN THE UNIT IS ‘LIVE’ WITH RESPECT TO ELECTRICAL OR PRESSURE SUPPLIES, A HAZARD MAY EXIST IF THE UNIT IS OPENED OR DISMANTLED.

2. UNITS MUST BE SELECTED AND INSTALLED BY SUITABLY TRAINED AND QUALIFIED PERSONNEL IN ACCORDANCE WITH APPROPRIATE CODES OF PRACTICE SO THAT THE POSSIBILITY OF FAILURE RESULTING IN INJURY OR DAMAGE CAUSED BY MISUSE OR MISAPPLICATION IS AVOIDED.

OPERATING PRINCIPLES Process pressure is sensed by a diaphragm that generates a force proportional to the applied pressure. This force is opposed by an adjustable spring which, at the point of equilibrium permits movement of an operating rod which actuates a switch or switches.

Note: Should the diaphragm fail the process will vent to atmosphere via a control orifice without pressurising the switch enclosure.

INSTALLATION The instruments are designed to be mounted vertically with the process connection underneath. However, mounting up to 45° from the vertical in any plane is acceptable, although a small calibration shift may occur. They can be mounted either direct to process, or to a wall or panel using the four mounting holes provided. Select the mounting point so as to avoid excessive shock, vibration or temperature fluctuation. Instruments should be mounted to avoid excessive heat transfer from the process lines or adjacent plant. To avoid undue stresses being imparted to the instrument when wall / panel mounted, it is recommended that a short length of flexible line be installed between the instrument and process line.

Take care to select and install adaptors to the electrical entry that do not reduce the enclosure degree of protection.

NOTE: Enclosure Codes H, T & B for NEMA 4X use. To ensure performance of enclosure, careful installation and sealing of cable gland in situ is required.

On enclosures H, R, T, B and U, remove the lid using an appropriate tool if tight eg edge of spanner or metal rod (fig 2).

OPTIONS AND TREATMENTS SPECIAL ENGINEERING

Use a spanner to support the process connection when fitting the instrument. When fitting the instrument lid make sure the ‘O’ ring is in good condition and fitted correctly.

On enclosures H, R, T, U, B remove the lid using an appropriate tool if tight eg edge of a spanner or metal rod (see fig 2).

WARNING: CHECK THE CONNECTION THREAD SIZE AND SPECIFICATION ON THE UNIT TO AVOID MIS-MATCHING WITH THE PROCESS CONNECTION ADAPTOR. SEE DIGIT 11 OF PRODUCT CODE.

Wire in accordance with local and National codes. Use cables no larger than 2.5 mm2 (14 AWG). Deliver electrical connection through a suitable cable gland

which will maintain the IP rating of the instrument. Insert bare wires fully into the terminal block and tighten securely. Keep wiring tails to a minimum and check that wires do not interfere with the operating mechanism. Use the earthing / grounding points provided.

CERTIFIED ENCLOSURES All series S20 pressure switches can be supplied with enclosures for use in hazardous areas to the following standards:

Zone 1 (Div 1) IEC 79-1 BS 5501: Parts 1 and 5: EN50 014 and EN50 018 CENELEC. Codes ‘H’ for aluminium EEx d IIC T6, and ‘R’ for stainless steel EExd IIC T6.

DIV 1 (NEC 500) Class I Groups C and D, Class II Groups E, F and G. Codes ‘T’ for aluminium and ‘U’ for stainless steel.

The above mentioned enclosures are suitable for outdoor use rated IP 66 / NEMA 4. Only operation, maintenance or repair procedures either contained herein or approved by Delta Controls may be used, to avoid rendering the equipment unsafe in operation and/or nullifying the Certification. NO MODIFICATIONS ARE PERMITTED.

Japanese Zone 1. Same as CENELEC Zone 1 IEC 79 with additional label and alternative terminal arrangement. Code ‘B’ for aluminium IIC T6. Refer to appropriate Japanese standards for guidance on installation and use.

Electrical Adaptors Use only certified adaptors for Zone 1/Div 1.

WARNING: IT IS A REQUIREMENT OF SAFETY THAT AT LEAST 5 FULL THREADS ARE ENGAGED BETWEEN THE ADAPTOR AND CONDUIT ENTRY.

References for Selection and Installation BS 5345 Part 3 for Enclosure Codes H and R. BS 5501 Part 1 for Enclosure Codes H and R. BS 5490 IEC 529 IP RATING (Ingress Protection) NEC ARTICLE 500 for Enclosure Code T and U.

MAINTENANCE Inspections should be carried out at quarterly to yearly intervals depending upon operating conditions.

Isolate the unit from process and power and remove the lid. Check all terminals for tightness. Check that cable tails are not fouled or chafed. Check for internal condensation. Rectify as necessary.

It is recommended that instruments used to provide an alarm are operated periodically to ensure they are functioning correctly.

If further maintenance is required seek advice from DELTA CONTROLS before attempting repair or replacement of parts.

CAUTION Moving parts have been treated with a water repelling lubricant before leaving the factory. Occasional inspection and the application of a water repelling lubricant is recommended to ensure moving parts remain free under all conditions.

WARNING: DOES NOT APPLY TO OXYGEN SERVICE.

Zone 1 Enclosure (H, R, T, U, B) Thread seal and contact surfaces must be lightly lubricated using a non-setting non-corrosive grease compatible with the lid seal. Do not use copper bearing grease. Screw on lid hand tight making sure that mating surfaces of the lid and enclosure are in contact. Re-tighten the lid lock screw.

WARNING: IT IS A SAFETY REQUIREMENT THAT AT LEAST 5 FULL THREADS ARE ENGAGED WHEN THE UNIT IS IN OPERATION. NEVER OPERATE THE UNIT UNLESS THIS CONDITION IS MET. DO NOT USE GREASES OR LUBRICANTS NOT COMPATIBLE WITH THE ENVIRONMENT OR PROCESS.

Weather-proof Enclosure (W) If lid gasket is dried out or damaged, replace with new greased gasket. Make sure gasket aligns correctly with sealing faces.

Stainless Steel Weather-proof Enclosure (A) Check gasket. If damaged, replace.

OPERATION Pressure switches are supplied calibrated against falling pressure unless otherwise specified. Set Point adjustment refers to falling pressure. Switching differential is the difference between the set point and the operating value on rising pressure. For opening details see Figs 2, 6, 7, 8.

Set Point Adjustment: Models S21, S22 (Figs 3, 4) 1. Isolate the instrument from the process and power. 2. Loosen lid lock screw and remove the lid. 3. Retain in a safe place to avoid damage to threads. 4. Slacken the set point lock screw. 5. Rotate the set point adjuster screw as required. Rotate clockwise to increase the set point and counter-clockwise to decrease the set point. 6. Tighten the set point lock screw. 7. Replace the instrument lid (see maintenance).

Switching Differential Adjustment: Models S22 (Figs 3, 4, 5) 1. Isolate the instrument from process and power. 2. Loosen lid lock screw and remove the lid. 3. Retain in a safe place to avoid damage to threads. 4. Rotate the knurled plastic wheel on the microswitch to adjust the switching differential. Rotate clockwise to increase differential and counter-clockwise to reduce differential. Note: Rotating the knurled plastic wheel will alter the operating value on rising pressure only. 5. Replace the instrument lid (see maintenance).

Note: For accurate setting, a suitable pressure gauge must be used in conjunction with the above procedure. Do not attempt to set the switch outside the scale limits. Though the unit may be set anywhere within its operation range, for optimum performance, it is good practice to have a set point value between 25% and 75% of span.

Low Voltage Directive (LVD) – 73/23/EC Amended by 93/68/EEC. Switch products with enclosure codes ‘W’ and ‘A’ supplied CE-marked must be installed and used in accordance with the main instructions and this addendum supplied with each product. Products rated lower than 50V ac and 75 V dc are outside the scope of the LVD, and therefore, do not require CE-marking under this directive. The LVD does not apply to products with enclosure codes ‘H’, ‘K’, ‘R’, ‘M’, ‘N’ for use in hazardous areas. Switch products with enclosure codes ‘H’, ‘K’, ‘R’, ‘M’, ‘N’, are covered by the Explosive Atmospheres Directive ATEX – 94/9/EC and when CE-marked will indicate compliance with this directive alone. The following directives do not apply to switch products manufactured by Delta Controls: Electromagnetic Compatibility EMC – 89/336/EEC amended by 93/68/EEC. Machinery Safety Directive MSD – 89/392/EEC amended by 93/68/EEC.

WIRING ENCLOSURE ‘W’ Cable Glands and adaptors – If enclosure ‘W’ is supplied with a through hole of 22 mm blanked with a blind grommet. Discard the grommet and fit a suitable proprietary brass or nylon M20 cable gland with thread length of 10 mm and locknut. Fit the nylon reducer provided to the inside and a fibre washer to the outside. See diagram 1. Alternately, the enclosure may be supplied from the factory with a threaded adaptor ready to accept the customer’s gland or conduit system. Alternatives: i) a metal or nylon adaptor may be used to accommodate other sizes of gland eg NPT, or conduit system. See diagram 2. ii) an elbow kit may be supplied to enable the entry to be rotated axially through 90° and radially through 360°. See diagram 3. Earthing / grounding – The user must make suitable local earthing arrangements, if required, to ensure that metal glands are earthed. An earthing point is provided inside the enclosure. If this is disturbed in any way it must be reassembled correctly to be an effective earth and prevent ingress. See diagram 4. When removing the lid slacken the M4 nut first and ensure it is re tightened whenever the lid is replaced. See diagram 4.1. ENCLOSURE ‘A’ Cable Glands and adaptors – Enclosure ‘A’ is supplied with an M20 x 1.5 tapped hole. Use a suitable stainless steel cable gland and sealing washer. Alternately the enclosure may be supplied with a threaded adaptor fitted at the factory ready to accept the customer’s gland or conduit system. See diagram 5. Earthing / grounding – Bonding between the enclosure and gland / adaptor will be achieved when both parts are screwed together. An earthing point is provided inside the enclosure. If this is disturbed in any way it must be reassembled correctly to be an effective earth and prevent ingress. See diagram 4. EARTHING / GROUNDING OF PROCESS CONNECTION AND BACK PLATES – All the internal dead metal work is bonded to the enclosure earthing point. Due to requirements of sealing, the process connection and back plates may be isolated from the earthing point. Do not, therefore, rely on either for earthing, instead always use the earthing point provided. If required, the process connection and back plates may be bonded locally. Never use the process connection or inlet pipe for locally grounding welding equipment unless it is separately earth bonded.

Pollution degree – all products are suitable for use in pollution degree 3. For extreme conditions where condensation may readily form, then sealed contacts should be used. See Table A codes 08/09, 0G/0H, H2/H3/H6. Electrical isolation – These products are not suitable for electrical isolation. Always isolate circuit separately to carry out any electrical work.

DISPOSITIVO DI PESATURA WEIGHING DEVICE



2 2 - Il dispositivo di pesatura serve ad indicare il peso di agente estinguente nella bombola. Il dispositivo deve

essere tarato per segnalare un valore pari al 10% della carica totale della bombola. - The weighing device is used for indicating the weight of the extinguishing agent in the steel cylinders. The

weight must be adjusted until a leakage indication is given when a max. of 10% weight-loss of the cylinder contenets has occured.

Taratura / Calibration - La tabella riportata indica il peso da applicare in funzione del peso della bombola carica. - According to the cylinder weight inclusive of its contents, different counter-weight are used

* La costante di taratura indica la variazione nel peso di anidride carbonica segnalata per ogni giro del dado di

regolazione. * The adjusting constant indicates the carbon dioxide weight variation signalled at every turn of the adjustable

nut. Taratura del dispositivo di pesatura / Adjustment of the weighing device 1. Avvitare il dado di regolazione fino a quando il peso rimane in posizione di equilibrio orizzontale.

Screw the adjusting nut into the threaded stud until the weight stays in balance horizontal position. 2. Girare in senso orario il dado fino ad indicare una perdita di peso del 10%. Turn the nut clockwise till a weight loss 10%. 3. Bloccare il dado e piombare il peso con filo di rame. Lock the nut and lead the weight with copper wire.
