8 | Commissioning
8.1 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.
Checkthecompressorfortransportdamage!
8.3 Leaktest
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.
INFO
Toprotectthecompressoragainstinadmissibleoperatingconditions,
highpressureandlowpressurepressostatsaremandatoryonthe
installationside.
DANGER Riskofbursting!
The compressor must only be pressurised using nitrogen (N
2
).
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.
8.2 Pressureintegrity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.
