1| Safety

These assembly instructions describe the standard version of the compressors named in the title manufactured by GEA. GEA refrigerating compressors are intended for installing in a machine (within the EU according to the EU Directives 2006/42/EC Machinery Directive, 97/23/EC PressureEquipmentDirectiveand2006/95/EC–LowVoltageDirective).Commissioning is only permissible if the compressors have been installed in accordance with these assembly instructions and the entire system into which they are integrated has been inspected and approved in accordance with legal regulations.

The compressors are intended for use with CO2 in transcritical and/or subcritical systems in compliance with the limits of application.

Onlytherefrigerantspecifiedintheseinstructionsmaybeused.

Any other use of the compressor is prohibited!

1.4 Intended use

WARNING The compressor may not be used in potentially explosive environments!

1.3 Safety instructions

WARNING Riskofaccident.Refrigerating compressors are pressurised machines and therefore requireparticularcautionandcareinhandling.

The maximum permissible overpressure must not be exceeded,even for testing purposes.

Riskofburns!-Dependingontheoperatingconditions,surfacetemperaturesof over 60 °C on the pressure side or below 0 °C on the suction side can be reached.- Avoid the contact with refrigerant under any circumstances. Thecontactwithrefrigerantcan leadtosevereburnsandskin irritations.

Danger of suffocation.CO2 is a nonflammable, acidic, colorless and odorless gas and heavier than air.NeverreleasesignificantvolumesofCO2 or the entire contents of the system into closed rooms!

Safety installationsaredesignedoradjusted inaccordancewithEN 378-2 or appropriate safety standards.

• Transcritical CO2 applications are still in the development phase.•Theyrequireacompletelynewkindofsystemandcontrol.• They are not a general solution for the substitution of F-gases.•Therefore, we expressly point out that all information in this assembly instruction has been provided according to our current levelofknowledgeandmaychangeduetofurtherdevelopment. Legal claims based on the correctness of the information cannot be made at any time and are hereby expressly excluded.

Materialsoldering/weldingconnection:S235(JRG2C) The pipe connections have graduated inside diameters so that pipes with standart millimetre and inch dimensions can be used. The connection diameters of the shut-off valves are rated for maximum compressor output. Theactualrequiredpipecrosssectionmustbematched to the output. The same applies for non-return valves.Fig. 11: graduated

internal diameter

4.3 Connecting the pipelines - solder system

ATTENTION Damage possible.

Superheating can damage the valve.Remove the pipe supports therefore from the valve for soldering and accordingly cool the valve body during and after soldering.Only solder using inert gas to inhibit oxidation products (scale).

• On its high-pressure side, the compressor has a shut-off valve with multi-sided cutting ring for safe installation of the discharge line.

Cutting ring function before tightening the union nut

4.4 Connecting the pipelines - cutting ring system

Tubepreparation:

The tube has to be sawn in a right angle. An angular tolerance of ±1° is permissible. Slightly trim the pipe ends inside and outside. For thin walled steel pipes or soft pipes made of nonferrous metal, reinforcing sleeves have to be used.

Pipeassembly:

Push Union Nut (5) and Cut Ring (3) onto Pipe (2). Insert pipe into Socket (6) as far as it will go and firmly press against pipe stop, otherwise incorrect assembly. Hand tighten union nut until socket, cutting ring and union nut are locked. Tighten union nut 1 ½ turns using a spanner wrench. The cutting ring is noticeably locked to the socket face (for assembly inside pipe connection, hold up valve with a spanner wrench). This should cause the cutting ring with its cutting edges to cut into the pipe resulting in a visible collar. In order to stick to the turns we recommend using marking lines on union nut and pipe. After assembly, it is necessary to check the collar. The gasket must not be damaged. At least 80% of the cutting face has to be covered. After check-up, screw on and tighten again as described above.

CAUTION Riskofinjury.

The compressor must be depressurised through connections A andBbeforecommencinganyworkandpriortoconnectingtotherefrigerant system.

Pipes and system components must be clean and dry inside and free of scale, swarf and layers of rust and phosphate. Only use hermetically sealed parts.

Lay pipes correctly. Suitable vibration compensators must be provided to prevent pipes being cracked and broken by severe vibrations.

Ensure a proper oil return. Keep pressure losses to an absolute minimum.

ATTENTION Property damage possible.

The compressor as delivered is equippedwith Schrader valves on the high and low pressure connections. These are used exclusively for changing with inert gas in the factory, and under no circum-stances may they be connected to the refrigeration circuit (the Schrader valves are approved for overpressure up to 28 bar only)!

6.1 Preparations for start-up

The compressor has undergone trials in the factory and all functions have been tested. There are therefore no special running-in instructions.

Checkthecompressorfortransportdamage!

INFO In order to protect the compressor against inadmissible opera-tingconditions,high-pressureandlow-pressurepressostatscontrols are mandatory on the installation side.

WARNING When the compressor is not running, depending on ambient temperature and amount of refrigerant charge, it is possiblethat the pressure may rise and exceed permitted levels for the compressor.Adequateprecautionsmustbetakentopreventthishappening(e.g.usingacoldstoragemedium,areceivertank,asecondaryrefrigerantsystem,orpressurereliefdevices).

6.3 Leaktest

Carry out the leak test on the refrigerating plant in accordance with EN 378-2 or a corresponding safety standard, while always observing the maximum permissible overpressure for the compressor.

DANGER Riskofbursting!The compressor must only be pressurised using nitrogen (N2). Never pressurise with oxygen or other gases!The maximum permissible overpressure of the compressor must not be exceeded at any time during the testing process (see name plate data)! Do not mix any refrigerant with the nitrogen as this could cause the ignition limit to shift into the critical range.

6.2 Pressure strength test

The compressor has been tested in the factory for pressure integrity. If however the entire system is to be subjected to a pressure integrity test, this should be carried out in accordance with EN 378-2 or a corresponding safety standard without the inclusion of the compressor.

6.4 Evacuation

First evacuate the system and then include the compressor in the evacuation process. Relieve the compressor pressure. Open the suction and pressure line shut-off valves. Turn on the oil sump heater. Evacuate the suction and discharge pressure sides using the vacuum pump. The vacuum has to be broken with nitrogen several times between the evacuation. At the end of the evacuation process, the vacuum should be < 1.5 mbar when the pump is switched off. Repeatthisprocessasoftenasisrequired.

6| Commissioning

Make sure that the suction and pressure line shut-off valves are open.

6.5 Refrigerant charge

Fillingtheliquidrefrigerant:Itisrecommendedthatthesystemfirstbefilledat standstill with gas on the high-pressure side up to a system pressure of at least5.2bar(ifitisfilledbelow5.2barwithliquid,thereisariskofdryiceformation).Furtherfillingaccordingtosystem.

To eliminate the possibility of dry ice formation when the system is operating (duringandafter thefillingprocess), theshut-offpointof the low-pressureswitch should be set to a value of at least 5.2 bar.

Arefrigerantsupplement,whichmaybecomenecessaryafterstart-up,canbe topped up in vapour form on the suction side.

ATTENTION Do not start the compressor if it is under vacuum. Do not apply any voltage - even for test purposes (must only be operated with refrigerant).Under vacuum, the spark-over and creepage current distances of the terminal board connection bolts shorten; this can result in winding and terminal board damage.

ATTENTION Avoidoverfillingthemachinewithrefrigerant! Do not charge liquid refrigerant into the suction-side on the

compressor. Do not mix additives with the oil and refrigerant.

CAUTION Wear personal protective clothing such as goggles and protective gloves!

WARNING Never exceed the max. permissible pressures while charging. Precautionsmustbetakenintime.

INFO Depending upon design of the CO2 refrigerant filling bottle(with/without tubing) CO2 can be filled in liquid after weight or gaseously.Use only high-dried CO2quality(see chapter 3.1)!

6.7 Pressure switch

Check that the safety and protection devices (pressure switch, motor protection, electrical contact protection measures, etc.) are functioning properly.

Switch on the compressor and let it run for at least 10 minutes. Themachineshouldreachastateofequilibrium. Check the oil level: The oil level must be visible in the sight glass. After a compressor is replaced, the oil level must be checked again. If the level is too high, oil mustbedrainedoff(dangerofoilliquidshocks;reducedcapacityoftherefrigeratingsystem).

Suitably adjusted pressure switches that switch off the compressor before reaching the maximum permissible operating pressure must be installed in the system. The pressure reduction for the pressure switches can occur either at the suction and pressure lines between the shut-off valve and compressor or at the non-lockable connections for the shut-off valves (connections A and B, see Chapter 9).

WARNING Ensure that both shut-off valves are open before starting the compressor!

6.9 Avoid slugging

7.1 Preparation

7| Maintenance

Topreventslugging: The complete refrigeration plant must be properly designed. All components must be compatibly rated with each other with regard to output (particularly the

evaporator and expansion valves). Suction gas superheating at the compressor input should be > 10 K (check the setting of the

expansion valve). Regard oil temperature and pressure gas temperature. (The pressure gas temperature has to be

high enough min. 50°C, so the oil temperature is > 30°C). Thesystemmustreachastateofequilibrium. Particularlyincriticalsystems(e.g.severalevaporatorpoints),measuressuchastheuseofliquidtraps,solenoidvalveintheliquidline,etc.arerecommended.

There should be no movement of refrigerant in the compressor while the system is at a standstill.

ATTENTION Slugging can result in damage to the compressor and cause refrigeranttoleak.

WARNING Beforestartinganyworkonthecompressor: Switch off the compressor and secure it to prevent a restart. Relieve compressor of system pressure.Preventairfrominfiltratingthesystem!Aftermaintenancehasbeenperformed: Connect safety switch. Evacuate compressor.Releaseswitch-onlock.

WARNING The decompression has to be carried out in a way that no dry ice respectively solid CO2 is producedwhich blocks the outlet andcould hinder the streaming out of CO2. Otherwise, there is the danger that pressure can be built up again.

7.6 DecommissioningClose the shut-off valves on the compressor. CO2 does not need to be recycled and can therefore be blown off into the environment. It is essential to ensure good ventilation or conduct the CO2 into the outdoors to avoid danger of suffocation. When releasing CO2, avoid a fast drop in pressure to prevent oil from exiting with it. If the compressor is unpressurized, remove the piping on the pressure- and suction-side (e.g. dismantling of the shut-off valve, etc.) and remove the compressor using an appropriate hoist. Dispose of the oil inside in accordance with the applicable national regulations.When decommissioning the compressor (eg. for service or replacement of the compressor) larger amounts of CO2intheoilcanbesetfree.Ifthedecompressionofthecompressorisnotsufficientenough, closed shut-off valves may lead to intolerable excessive pressure. For this reason the suction side (LP) and the high pressure side (HP) of the compressor have to be secured by decompression valves.

7.5 LubricantsFor operation with CO2 the GEA oil C 85 E is necessary!

7.2 Worktobecarriedout

In order to guarantee optimum operational reliability and service life of the compressor, we recommend carrying out servicing and inspection work at regular intervals: Oilchange:

- not mandatory for factory-produced series systems. - forfieldinstallationsorwhenoperatingneartheapplicationlimit:forthefirsttimeafter100

to 200 operating hours, then approx. every 3 years or 10,000 - 12,000 operating hours. Dispose of used oil according to the regulations; observe national regulations.

Annual checks: Oil level, leak tightness, running noises, pressures, temperatures, function of auxiliary devices such as oil sump heater, pressure switch.
