Webasto or Espar manuals for more information.

If there are no heater faults, the heater
will go through a normal start cycle and regulate
based on thermostat setting.

Switch on the preheating system briefly
about once a month, even during the warm
season.
Caution:
When welding on the vehicle,
disconnect the preheater module connector in
order to protect this system from voltage surges.

do not turn on the preheating system for more
than one hour before starting the engine.

The preheating system uses the
same fuel as the engine. Do not operate in a
