• Check the power supply for correct polarity.
• Ensure the operating device is set to its highest
setting.

Please Note!
Combustion may not be established when the heater is
first operated. Several attempts may be required to start
the heater. This is due to air being present in the heater’s
fuel lines, that needs to be purged by the fuel-metering
pump.
Operating instructions
The heater is operated by a control unit.
The control unit is accompanied by detailed operating
instructions which you will receive from the company
installing the heater.
Please Note!
The control elements (e.g. mini timer, module timer) are

After a longer interval in operations (after the summer
months) the fuse must be put in position and/or the
heater connected up to the battery. Check that all parts
fit firmly (tighten screws where necessary).
Check the fuel system visually for any leaks.
Refer back to Technical Description and Operating
Instructions for full operation and function of heater.
Initial commissioning
The following points are to be checked by the company
installing the heater during initial commissioning.
• After installation of the heater, the coolant circuit
and the whole fuel supply system must be vented
carefully. Comply with the instructions issued by the
vehicle manufacturer.
• During the trial run of the heater, check all water and
fuel connections for leaks and firm fitting.
• If the heater shows a fault during operation, find and
eliminate the cause of the fault using a diagnosis unit.
