WARNING Whenthecompressorisnotrunning,dependingonambient
temperatureandamountofrefrigerantcharge,itispossiblethat
the pressure may rise and exceed permitted levels for the com-
pressor.Adequateprecautionsmustbetakentopreventthishap-
pening(e.g.using a coldstoragemedium,a receivertank,ase-
condaryrefrigerantsystem,orpressurereliefdevices).
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.
Checkthecompressorfortransportdamage!
INFO
Toprotectthecompressoragainstinadmissibleoperatingconditions,
high pressure and low pressure pressostats are mandatory on the
installation side.
6.2 Pressure strength test
The compressor has been factory-tested for pressure resistance. The following must be observed if
the entire plant is subjected to an additional pressure strength test:
Test the refrigeration circuit according to EN 378-2 or a corresponding safety standard.
6.3 Leaktest
Carry out the leak test of the refrigerating system in accordance with EN 378-2 or a corresponding
safety standard without including the compressor.
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.
DANGER Riskofbursting!
Do not mix any refrigerant with the nitrogen (N
2
) as this could cau-
se the ignition limit to shift into the critical range.
