General
The auxiliary heater fulfils the following functions:
– Pre-heating and maintaining a set temperature in the cabin and/or engine, with a
non-running engine.
– Additional heating of the cabin interior in extreme cold or when the cabin heater
cannot heat the cabin (engine idling for a long period).
The auxiliary heater is connected to the engine coolant circuit.
The heat is fed to the cabin through the existing heat exchanger (heater fan) and the
air vents and outlet openings of the vehicle.
NOTE: Switch off the fan heating and ventilation system and the auxiliary
heater when leaving the vehicle for a long period of time.
NOTE: To prevent faults during cold weather, switch on the auxiliary heater
for 10 to 15 minutes once a month during the summer. Do this while the
engine is still cold otherwise the rest heat function prevents the auxiliary
heater to start.
If necessary, install a separate fuel tank for the auxiliary heater.
