* PTC heater with temperature control
PTC Heaters 60 W and 120 W
These two PTC heaters are self-regulating.
The current consumption drops with increasing
crankcase temperature, thereby conserving energy. A bore at the bottom (front or side) of the
compressor housing is provided for the heater. A plastic plug protects this bore.
Electric Supply
The heater can be connected to the free connection terminals in the compressor connector box.
Connect the heater so it is on when the compressor is not running; please see the Electrical Data
– Section 5 of this manual.
