72/245/EEC (EMC) and ECE R122 and 2001/56/EC (heater) with the following EC permit
numbers:
e1*72/245*2006/96*5529 (Air Top Evo 3900 / 5500)
E1 03 5529 (Air Top Evo 3900 / 5500)
e1*2001/56*2006/119*0255 (Air Top Evo 3900)
E1 00 0255 (Air Top Evo 3900)
e1*2001/56*2006/119*0256 (Air Top Evo 5500)
E1 00 0256 (Air Top Evo 5500)
NOTE:
The specifications of this Directives are binding in the scope of the basic
Directives 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
compartments.
4. Claims can only be made if it can be verified that the claimant has complied with the
servicing 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
(flashing 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 diesel fuel specified by the vessel 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 vessels 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.
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.

General
information
Using the Control Panel Air Top EVO MC04, The Air Top Evo heaters show
their full functionality with the new user interface Air Top Evo M.
The control panel is to switch on/off, as well as to preselect the operation
modes and the interior temperature. For technical data as well as
references to the installation, see the installation instructions of the
specific heater.

Operation
Main switch ON / OFF
Switching on the heater
By pressing the main switch ON / OFF the heater is activated.
After switching on, the main switch illuminates and the indicator "ON /
Status" lights to confirm the heater operation.
Switching off the heater
By pressing the main switch ON / OFF again the heater operation is
stopped.
After switching off, the lighting of the main switch is also off.
The indicator "ON / Status" goes off after approx. 3 minutes (cooling
down of the heater).
Mode selector knob
With the mode selector knob you can select the desired functions of your
heater by placing the index on the desired symbol.
- “Eco” mode reduces the electrical power consumption by reducing the
max. heating power. Useful when saving the battery is more important
than quick heating up.
- In the “Normal” heating the heater behaves like a standard heater.
- “Plus” increases the max. heating power by ~10%. It provides extra
power for quicker heating up.
- In “Ventilation” mode the blower runs but the heater is off.
Temperature selector
You can adjust the desired interior temperature with the temperature
selector. Preferably the temperature selector should be in the marked
range of the scale (comfort range).
LED
The status LED lights green in normal heating mode. Blinking indicates
failure code; see the following faults section.
Error code
Faultless operation:
The normal operation of the equipment is represented by the status
indicator, illuminating green light.
After switching off the heater (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 Webastotrained personnel.
Cause Remedy

on again
Heater unit overheats and
indicator flashes
Make sure that hot air can flow freely, allow heater unit
to cool down, Switch heater unit off (for at least 2
seconds) and then on again
Vehicle voltage too low Charge battery
Switch heater unit off (for at least 2 seconds) and then
on again
Cause Remedy
Combustion air and/or exhaust
system blocked
Check combustion air and exhaust system for blockage
Actions in event of faults
Heater unit cuts out automatically
Heater unit emits black smoke
Page 6
The error code is communicated by a series of flashes from the status LED in the bottm right
corner of the bezel. After a sequence of 5 fast flashes the error code will be communicated
by a series of long flashes; refer to the table below for code explanations.
Example:
F 03 =
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.
