Webasto Thermo Top E Handbuch

Dear Webasto customer!

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. This

manual summarizes the main points of importance for using the heaters Thermo Top E, C

and P.

The water heaters Thermo Top E, C and P have been type-tested and approved in accordance

with Directives 2001/56/EC (heaters) and 72/245/EEC (EMC) within the territory governed by

European Directive 70/156/EEC.

The units must be installed in accordance with the enclosed installation instructions.

The heater must not be operated :

• In filling stations and tank farms.

• At locations at which highly flammable gases or dusts can

form, and at locations at which highly flammable liquids or

solid materials are stored (e.g. near fuel, coal and wood

dust, grain warehouses, dry grass and leaves, cardboard ,

paper, etc.)

• In enclosed rooms (e.g. garages), not even via the timer or

Telestart.

The heater must not:

• be exposed to temperatures of more than 120 °C (storage

temperature), otherwise the electronics may suffer

permanent damage.

• be operated without at least 20% brandname anti-freeze in

the water of the heating circuit.

The heater must:

• be operated with the fuel specified on the rating plate and

at the nominal voltage specified on the rating plate.

• be taken out of operation by removing the fuse if smoke

develops, if unusual burning noises are heard or if there is a

smell of fuel.

The heater must not be restarted until the unit has been

checked by personnel duly trained by Webasto.

• be operated for 10 minutes at least once per month, with

the engine cold and the fan set to the minimum setting.

The heater must be inspected by a specialist at the

beginning of the heating season or earlier.

Liability:

• Non-compliance with the installation instructions and the

warnings contained therein will lead to the exclusion of all

liability by Webasto. The same also applies if repairs are not

undertaken by professionals or without using genuine spare

parts. This invalidates the type approval for the heater and

its homologation / EC type permit.

The heater can be started via the timer or Telestart unit, depending on its configuration. If no

special instructions on adjusting the vehicle heating during auxiliary heater operation are

available, then the vehicle heating must be set to "warm" before switching on the heater.

The heater fan in the vehicle should be set to the 1st speed in the case of a 3-speed

fan and to the 2nd speed in the case of a 4-speed fan. Fans with infinitely variable

speed should be set to at least 1/3 of the fan performance.

NOTE:

We recommend that the heating time be set in accordance with the driving time.

Heating time = driving time

Example: For a journey lasting approx. 20 minutes (one way), the duty period should

not exceed 20 minutes.

If the optional summer / winter switch has been installed for the heater, it must be set in

accordance with the time of year. In this case, the heater will heat the interior of the vehicle

when set to the winter position and merely operate the vehicle fan to ventilate the

interior of the vehicle when set to the summer position .

Operation of the heater

If a fault occurs, check that the fuses and plug connections are in perfect condition and

secure.

When a fault occurs, the heater switches to the fault interlock; an error is not indicated on

the clock display.

Always try to cancel the fault interlock before calling a Webasto service centre.

The following faults can be remedied directly by the user:

Note:

The heater switches on again when the fuse is refitted.

Please contact a Webasto service centre if the fault cannot be remedied in this way.
