Operating Instructions
Air Top 2000 ST
(Control Rheostat Only)
Introduction
Dear Webasto Customer,
Thank you for choosing the Webasto Air Top 2000 ST air heater.
The Air Top 2000 ST heater is used
– to heat cabins, boats, trucks, minibuses, vans and motor homes and
– to defrost vehicle windows.
We presume that the principle and mode of operation of your new heater has been explained to your complete satisfaction by
the workshop/service centre which installed the heater. In these operating instructions we would like to once again provide you
with an overview of the safe use of the Air Top 2000 ST heater.
Repair or maintenance work not described here may only be carried out by an authorized Webasto dealer.
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. The year in which the heater was used for the first time must be permanently displayed on the factory plate by deleting the inappli-
cable years from the plate.
3. The heaters are not designed for heating hazardous substance transport compartments.
4. Webasto heaters must be switched "off" when re-fueling at filling stations and/or while loading or unloading flamma-
ble materials for transport, to prevent the risk of explosion. Please review the owner's manual for safety and use
instructions.
5. The heater may not be operated in enclosed spaces (such as garages) as a result of the risk of poisoning and asphyxia-
tion, even if a timer or remote is used.
6. In the event of long-lasting heavy smoke development, unusual combustion noises or a smell of fuel or if the heater suffers continu-
ous fault cut-outs with error messages (flashing code), it must be shut down by removing the fuse and must not be used until it has
been inspected by Webasto-trained personnel.
7. Wherever inflammable vapors or dust may form (for example in the vicinity of fuel, carbon, wood dust, etc...), the
heater must be switched off as a result of the risk of explosion.
8. 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.
9. The fuel specified by the vehicle manufacturer is suitable for use in the Air Top 2000 ST B (petrol EN228).
10. The diesel fuel specified by the vehicle manufacturer is suitable for use in the Air Top 2000 ST D (diesel EN590).
– 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.
11. 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.
12. Noncompliance 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 with the use of parts other than genuine spare parts. This will
result in the invalidation of the type approval for the heater unit, and therefore of its homologation/EC type licence.
13. Keep the hot air inlet and hot air outlet free of dirt and foreign bodies. Soiled or blocked hot air lines may cause overheating, and
therefore result in the overheating cut-out tripping.
14. To prevent mechanical parts seizing, the heater should be operated for approx. 10 minutes every four weeks.
15. Do not stand on the heater and do not place any heavy items on the heater or throw items at the heater.
16. 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.
17. 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.
18. The heater must not be cleaned with a high pressure cleaner.
