NOTE:
The provisions of these Directives are binding within the territory governed by EU
Directive 70/156/EEC and should similarly be observed in countries without specific
regulations.

3. The heaters are not designed for heating hazardous substance transport
compartments.

5. The heater must be switched off at filling stations and tank farms as a result of the risk
of explosion.

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.

9. Wherever inflammable vapours 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.

11. The fuel specified by the vehicle manufacturer must be used for the Air Top 2000 ST B
heater (petrol). Both leaded and unleaded fuel may be used.
The diesel fuel specified by the vehicle manufacturer must be used for the Air Top 2000
ST D heater (diesel). Class EL heating oil (not L heating oil) may also be used as long as
it complies with the normal quality available on the German market pursuant to
DIN 51603.

The Air Top 2000 ST D heater is also licensed for use with PME (bio-diesel), which
complies with DIN EN 14214.
We know of no negative influences due to additives.
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 (storage
temperature). If the temperature exceeds this level there is a risk of permanent damage to
the electronics systems.

13. Failure to follow the installation instructions and the notes contained therein will lead
to all liability being refused 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.

14. Keep the hot air inlet and hot air outlet free of dirt and foreign bodies.
Contaminated or blocked hot air lines may cause overheating and thus result in the
overheating cut-out tripping.

15. To prevent mechanical parts seizing, the heater should be operated for approx.
10 minutes every four weeks.

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.

18. The current of hot air in the heater must not be restricted or blocked by highly
inflammable substances or materials such as rags, cleaning wool, etc.

19. The heater must not be cleaned with a high pressure cleaner.

The Air Top 2000 ST heater is switched on and off by hand using a switch. Automatic
controls must not be used.
In class FL vehicles these heaters must not be used during loading and unloading
procedures or at loading points.
In class FL vehicles the heaters are switched off automatically and the combustion air
supply is interrupted for a maximum of 40 seconds if:
– the vehicle's engine is at a standstill; in this case the heater can be switched on
again by hand.
