Maintenance and Safety Information
1. Caution: 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. Heater must be switched "off" when refueling 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 installation of the heaters must be performed in accordance with the Installation
Instructions. If available, the approval certification is to be kept in the vehicle.
4. The year of the initial operation must be durably marked on the type plate of the
heater by removing the years that are not applicable.
5. The heaters are not approved for use in the cargo space of vehicles carrying
hazardous materials.
6. Claims can only be asserted if the claimant can prove that the maintenance and safety
notes were adhered to.
7. Due to the danger of explosion the heater must be switched off at filling stations
and tank farms.
8. Due to the danger of poisoning or asphyxiation the heater must not be operated
in enclosed spaces (e.g. garages) without adequate exhaust extraction. This
should be considered when pre-setting heater operating times or using the
Telestart remote control.
9. The heater must be inspected by a qualified expert annually, preferably prior to the
heating season commencing.
10. In the case of severe smoke development, unusual combustion noises or fuel
smell, the heater must be placed out of operation by removing the fuse and may only
be restarted after it was inspected by Webasto-trained personnel.
11. At locations where combustible vapours or dust may accumulate (e.g. in the
vicinity of fuel, coal, sawdust and grain depots or the like) the heater must be
switched off due to the danger of explosion.
12. Whenever the heater is removed it is mandatory that the gasket located
underneath be replaced.
13. The heat exchanger of the air heater is not to be used for longer than 10 years
and must thereafter be replaced by the manufacturer or one of the authorised
workshops with a genuine replacement part.
If exhaust pipes lead through passenger areas, these pipes must also be replaced
with genuine replacement parts after 10 years.
14. The fuel specified by the vehicle manufacturer is suitable as fuel for the heater . Both
leaded and unleaded fuel may be used.
15. The heater should not be exposed to temperatures greater than 85°C (storage
temperature). Exposure to such temperatures will cause permanent damage to the
electronics.

Maintenance and Safety Information
16. Webasto will not assume any liability if the installation instructions and the notes
contained therein are not observed and performed by a Webasto trained installer/repair
technician. The same applies to improperly performed repairs or those where others than
genuine replacement parts have been used. In those cases, the heater's General Design
Certification and thus the General Operating Permit (homologation) will be invalidated as
a consequence.
17. Heating air inlet and outlet openings must be kept clear of dirt and objects.
Contaminated or obstructed heating air ducts can result in overheating and thus tripping
of the temperature limiter.
18. To prevent mechanical parts from seizing, the heater should be operated every 4
weeks for approx. 20 minutes.
