Webasto Air Top 2000 ST User manual

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 motorhomes 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
authorised Webasto dealer.
1. The Air Top 2000 ST heater unit has been type- tested and approved in accordance with
EC Directives 72/245/EEC (EMC), 2001/56/EC (heater) with the following permit num-
bers:
e1 03 1085
e1 00 0022
NOTE:
The specifications of this Directive are binding in the scope of the Basic Directive
EEC/70/156 and/or EC/2007/46 (for new vehicle models from 29/04/2009) and
should also be observed in countries in which no special regulations exist.
2. 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.
3. The heaters are not designed for heating hazardous substance transport com-
partments.
To install the Air Top 2000 ST D heater unit in hazchem vehicles, the requirements of the
Directives EC/2001/56 and ECE R122 must be met.
4. Claims can only be made if it can be verified that the claimant has complied with the serv-
icing and safety instructions.
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.
7. The heater must be checked by an expert at the latest at the start of the cold weather
period.

8. In the event of long-lasting heavy smoke development, unusual combustion noises or a
smell of fuel or if the heater suffers continuous fault cut-outs with error messages (flash-
ing 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 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 is suitable for use in the Air Top 2000 ST
B (petrol EN228).
The diesel fuel specified by the vehicle manufacturer is suitable for use in the Air Top 2000
ST D (diesel EN590).
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 min-
utes 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 temper-
ature). 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 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.
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, and therefore result in the overheating cut-out trip-
ping.
15. To prevent mechanical parts seizing, the heater should be operated for approx. 10 min-
utes 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 inflamma-
ble substances or materials such as rags, cleaning wool, etc.
19. The heater must not be cleaned with a high pressure cleaner.

Control element
Set the rotary knob on the control element to the desired temperature.
NOTE:
To prevent the hot and combustion air fan from blocking or scraping, ensure that
there are no objects on or against the heater before you switch it on.
NOTE for ADR mode only:
The Air Top 2000 ST heater is switched on and off by hand using a switch.
The use of automatic control systems is prohibited.
In class FL vehicles these heaters must not be used during loading and unloading pro-
cedures 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.
- A pumping device that is part of the vehicle is started.
The control unit is then in fault lock-out mode. The ON/OFF switch must be set to
OFF before the heater can be restarted.
A separate switch allows the user to choose between heating and ventilation mode.
In ventilation mode the fan speed depends on the position of the control element.
Rotary knob for:
- Switching on and off
- Setting the room temperature
- Resetting after a fault cut-out

Combination timer
General infor-
mation
The combination timer allows the heater start time to be selected for
a period of up to seven days.
Three cut-in times can be programmed, although only one of them
may be activated.
The combination timer has a temperature setpoint generator.
When the ignition is switched on the timer shows the current time
and the day. When the heater is operating, the display and the but-
tons are lit.
When the timer is connected to the power supply all the symbols in
the display will flash. The time and day must be set. The display re-
mains blank in ADR vehicles.
Operation The operation of the timer is designed such that all the flashing sym-
bols can be adjusted using the and buttons. If no button is
pressed for five seconds the displayed time is saved. If the and
buttons are pressed for longer than two seconds, they will switch to
high speed adjustment.
If the ignition is switched off whilst the heater is in permanent heat-
ing mode, a remaining operating time of 15 minutes will appear on
the display and the heater will continue to operate.
Error code On heaters that output an error code (Air Top 2000 ST), a number,
the error code, may appear in the display. In this case you should visit
a Webasto service outlet.

If the system is fitted with a combination timer, when an error occurs an error code is output
on the timer's display until the heater has been rectified.
The error code is output if the heater is fitted with a control element after an error has oc-
curred by the switch-on indicator/error code indicator flashing. After a burst of fast flashes
the error code will be output by a sequence of long flashes, the number of which is shown
in the table below.
If serious malfunctions such as overheating or failure to start reoccur, the heater is locked
(F 12) and can be put back into service by disconnecting the power supply with the heater
switched on (e.g. by removing fuse).
