WARNING
The heater must not be operated:
• In filling stations and tank farms.
• At locations at which highly flammable gases or dusts
can form, and at which highly flammable liquids or solid
materials are stored (e.g. near fuel, coal and wood dust,
grain warehouses, dry grass and leaves, cardboard ,
paper, etc.).
• In enclosed rooms (e.g. garages), not even via the timer
or Telestart.
• Without at least 33 % brand name anti-freeze in the
water of the heating circuit.
There is a danger of burns, as the heater and the
attached parts may be extremely hot.
The heater including the control unit:
• may not be exposed to storage temperatures of more
than +125 °C. The operating voltage may be connected
at the time. Otherwise the electronics may suffer
permanent damage.
• may only be operated with the fuel specified on the type
label and at the nominal voltage specified on the type
label.
• must be shut down by immediately switching off the
heater and removing the fuse in case of heavy smoke,
unusual combustion noises or fuel odours. The heater
must not be restarted until the unit has been checked
exclusively by personnel duly trained by Webasto.
• must be switched off during work in the engine
compartment and may not be cleaned with high-
pressure cleaning units or compressed air.
• Must be put into operation at least once a year for 10
minutes with the engine cold and the lowest fan speed
selected.
• Must be checked by a professional every 2 years, at the
commencement of the heating period.
Liability:
• Non-compliance with the installation/operating
instructions and the warnings contained therein will
lead to the exclusion of all liability by Webasto. The
same applies if repairs are carried out incorrectly or with
the use of parts other than genuine spare parts. This will
result in the invalidation of the type approval for the
heater and therefore of its homologation/EC type
licence.
Be sure to read the operating instructions of the heater
before commissioning.
