Important:
- Start unloader may only be employed during the starting phase.
- Check the solenoid valve and the non-return valve regulary for tightness.
- In addition, we recommend to use a heat protection thermostat on the discharge side of the com
-
pressor. This protects the compressor against thermal overloading. Connect the heat protection
thermostat in series on the safety chain of the control circuit, to switch off the compressor if
necessary.
- Follow these instructions to avoid thermal overloading.

A rule of thumb:
Always lay the first pipe section starting from the shut-off valve
downwards and
parallel to the drive shaft.
ATTENTION Improperly installed pipes can cause cracks and tears which can
result in a loss of refrigerant.
INFO
Proper layout of the suction and pressure lines directly after the
compressor is integral to the smooth running and vibration beha-
viour of the system.
