Servicing
and
safety
instructions
1.
When heater is in use, the surface of the hot air outlet may become hot to the touch.
Contact with skin may cause burns.
2.
Webasto heaters must be switched “off” when re-fueling at filling stations and/
or while loading or unloading flammable materials for transport, to prevent the
risk of explosion. Please review owner’s manual for safety and use instructions.
3. The year in which the heater was used for the first time must be permanently
displayed on the factory plate by deleting the inapplicable years from the plate.
4.
The heaters are not designed for heating hazardous substance transport
compartments.
5. Claims can only be made if it can be verified that the claimant has complied with the
servicing and safety instructions.
6.
The heater may not be operated in enclosed spaces (such as garages) as a
result of the risk of poisoning and asphyxiation, even if a timer or Telestart remote
is used.
7. The heater must be checked by an expert at the latest at the start of the cold weather
period.
8. In the even of long-lasting heavy smoke development, unusual combustion noises or
a smell f fuel or if the heater suffers continuous fault cut-outs with error messages
(flashing code), it must be shut down by removing the fuse and must not be reused until
it has been inspected by Webasto trained personnel.
9. Wherever inflammable vapors or dust may form (for example in the vicinity of fuel,
carbon, wood dust or cereal stores or the like), the heater must be switched off as a
result of the risk of explosion.
10. The heat transfer unit on air heaters is exposed to very high thermal stress and
must be replaced by a genuine Webasto spare part ten years after it is used for the first
time.
If exhaust lines pass through areas used by personnel, they must also be replaced by
genuine spare parts after ten years.
