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 suers continuous fault cut-outs with error messages
(ashing code), it must be shut down by removing the fuse and must not be reused
until it has been inspected by Webasto-trained personnel.

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 Evo
3900 B/Air Top Evo 5500 B. Both leaded and unleaded fuel may be used.
The diesel fuel specified by the vehicle manufacturer is suitable for use in the Air Top
Evo 3900 D/Air Top Evo 5500 D. Class EL heating oil (not L heating oil) may also be
used as long as it complies to the normal quality available on the German market
pursuant to DIN 51603.
The Air Top Evo 3900 D/Air Top Evo 5500 D heaters are 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 unit 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. 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
tripping.
15. To prevent mechanical parts seizing, the heater should be operated for approx.
20minutes 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.

Combination timer
General
information 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
buttons 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
remains blank in ADR vehicles.
Operation The operation of the timer is designed such that all the flashing
symbols 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
heating 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 Evo 3900/Air Top
Evo 5500), a number, the error code, may appear in the display. In
this case you should visit a Webasto service outlet.

(main switch) the status indicator shows the normal cooling down
process of the heater. After the heater has cooled down normally,
the status indicator shuts off.
Fault:
During an operational fault a flashing code is displayed by the
status indicator. This function enables a professional workshop to
solve the fault in a fast way. In this case please visit a Webasto
service station!

If an error occurs, first check the fuse and plug connections to ensure that they are in
proper condition and connected correctly.
If the actions described below do not rectify the error, have the heater checked by
Webasto-trained personnel.

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
occurred 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 faults, such as overheating or no start, occur frequently, the heater will be set to
permanent fault lock-out (F 12) and cannot be restarted until it has been repaired by
Webasto-trained personnel.
