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 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.
