Operation of the heater
The heater can be started via the timer or Telestart unit, depending on its
configuration.
Before you switch on the heater, set the vehicle’s heating system to “hot”. The
vehicle’s fan switch is to be turned to position 1 in the case of 3-speed blower
fans, and to position 2 in the case of 4-speed blowers. Infinitely variable fans
are to be set to at least 1/3 of the fan's capacity.
NOTE:
We recommend that the heating time be set in accordance with the driving time.
Heating time = driving time
Example: For a journey lasting approx. 20 minutes (one way), the duty period
should not exceed 20 minutes.
