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.
11. The fuel specified by the vehicle manufacturer is suitable for use in the Air Top 2000 ST
B (gasoline).
The diesel fuel specified by the vehicle manufacturer is suitable for use in the Air Top 2000
ST D (diesel).
There are no known negative influences due to fuel additives when used appropriately.
If fuel is extracted from the vehicle’s tank, follow the additive instructions issued by the
vehicle manufacturer.
If you change to low-temperature fuel, the heater must be operated for approx. 15
minutes so that the fuel system is filled with the new fuel.
12. The temperature in the area around the heater must not exceed 85 °C / 185° F (storage
temperature). If the temperature exceeds this level there is a risk of permanent damage
to the electronics systems.
13. Non-compliance with the installation 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 by untrained technicians or with the use of parts other than genuine spare
parts. This will result in the invalidation of the type approval for the heater unit.
14. Keep the hot air inlet and hot air outlet free of dirt and foreign bodies. Soiled or blocked
hot air lines may cause overheating.
15. To prevent mechanical parts seizing, the heater should be operated for approx. 20
minutes once a month.
16. Do not stand on the heater and do not place any heavy items on the heater or throw
items at the heater.
17. Do not place any items of clothing, textiles or similar materials over the heater or in front
of the hot air inlet and the hot air outlet.

inflammable substances or materials such as rags, cleaning wool, etc.
