•
Before you carry out any repair work, disconnect the compressor from the electricity network
•
Turn the main switch to "O" (OFF)

Secure the main switch against an unauthorized restart
WARNING
•
Refrigerating compressors are pressurised machines and therefore require particular
caution and care in handling.
•
Only qualified personnel are allowed to perform any work on refrigeration compressors.
•
The national safety regulations, accident prevention regulations, technical rules and specific
regulations (EN 378 and others) must be taken into account absolutely.
•
Never put the safety switch out of action!
•
Prior to commissioning, check whether all the components installed by the user have been
fastened expertly and connected pressure-tight with the compressor (e.g. piping, plugs, union
nuts, replaced components etc.).
•
Before commissioning, evacuate the refrigerant systems carefully including the compressor and
afterwards charge refrigerant.
•
Prior to starting the compressor open discharge shut-off valve and suction shut-off valve.
•
Do not start the compressor in vacuum. Operate the compressor only when the system is charged.
•
Risk of burns! Depending on the operating conditions, surface temperatures of over 60 °C
on the pressure side or below 0 °C on the suction side can be reached.
•
The maximum permissible overpressure must not be exceeded, even for testing purposes.
•
Danger of injury! Never grab rotating parts during operation!
