During compressor standstill and depending on the pressure and ambient temperature, refrigerant
diffuses into the compressor's lubricating oil. This reduces the oil's lubricating ability. When the
compressor is started, the refrigerant contained in the oil evaporates due to the decline in pressure.
This can result in oil foaming and oil exodus which can result in oil hammer in certain circumstances.

Operation mode:

The oil sump heater operates when the compressor is shut down.

The oil sump heater is switched off when the compressor starts.

Connection:

Connect the oil sump heater via an auxiliary contact (or parallel-wired auxiliary

contactor) of the compressor contactor to a separate current path.
Electrical data: 230 V - 1 - 50/60 Hz, 140 W.

Fig. 23

ATTENTION

Connection to the current path of the safety control chain is not
permitted.
