4| Compressor assembly
Important:
-
Start unloader may only be employed during the starting phase.
-
Check the solenoid valve and the non-return valve regularly for tightness.
-
In addition, we recommend using 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.

Laying suction and pressure lines
A rule of thumb: Always lay the first pipe section starting from the shut-off valve downwards
and parallel to the drive shaft.
As short as
possible
Improperly installed pipes can cause cracks and tears, the result
being a loss of refrigerant.
Proper layout of the suction and discharge lines directly after
the compressor is integral to the system's smooth running and
vibration behavior.
