5.11 Oil sump heater (accessories)

In order to avoid damage to the compressor, the compressor must be equipped with an oil sump heater.

Connexion:

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

contact) of the compressor contactor to a seperate electric circuit.
Electrical data: 110 - 240 V - 1 - 50/60 Hz, 50 - 120 W, PTC-heater adjusting.

ATTENTION The oil sump heater must generally be connected and operated!
