When the compressor is at a standstill, refrigerant diffuses into the lubricating oil of the compressors
housing, depending on pressure and ambient temperature. This reduces the lubricating capacity of
the oil. When the compressor starts up, the refrigerant contained in the oil evaporates out through the

reduction in pressure. The consequences can be foaming and migration of the oil, causing oil shocks

under certain circumstances.

Operation:

The oil sump heater operates when the compressor is at a standstill. When the compres-

sor starts up, the oil sump heater switches off again automatically.

Connection:

The oil sump heater must be connected via an auxiliary contact (or parallel wired auxil-

iary contact) of the compressor contactor to a separate electric circuit.
El. data: 230 V - 1 - 50/60 Hz, 160 W.

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