Commissioning
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!
WARNING
All of the following work must be performed only by qualified
personnel (see page 4) and with exclusion of an explosive atmos-
phere.
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
.
6.3 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.
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.
INFO
In order to protect the compressor against prohibited operating
conditions, high- and low-pressure monitors are necessary in
accordance with the relevant national regulations!
