Webasto Thermo Top Z User manual

Dear Webasto Customer,
Thank you for choosing a Webasto Thermo Top Z, E, or C Water Heater.
We hope you will enjoy many years of additional comfort during your travels with it.
The Thermo Top E and C heaters are used in conjunction with the original vehicle heating
system
– to heat the passenger compartment,
– to defrost the vehicle windows and
– to preheat water-cooled engines.
The Thermo Top Z heater is only used as auxiliary heater for water-cooled engines.
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 heater.
To become familiar with and understand all functions of the heater, you must
read these operating instructions carefully.
Then you can be sure that you can use all functions to your satisfaction and
feel completely comfortable and safe.
If you should loose these instructions, please contact an authorised Webasto
dealer immediately to obtain a replacement copy.
Repair or maintenance work not described here may only be carried out by an
authorised Webasto dealer.
Within the territory governed by European Directive 70/156/EEC and/or EC/2007/46 for new
vehicle types from 29/04/2009), there are homologation approvals for the Thermo Top Z, E
and C water heaters in accordance with ECE R-122 (Heatings) and ECE R-10 (EMC).
The heater must not be started until the unit has been checked exclusively by per-
sonnel duly trained by Webasto.
The unit may only be installed professionally in accordance with the installation in-
structions.

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 % brand name anti-
freeze in the water of the heating circuit.
The heater:
• may only be operated with the fuel specified on the rating
plate and at the nominal voltage specified on the rating
plate.
• The heater must be taken out of operation by switching it
off immediately and 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 exclusively by personnel duly trained by
Webasto.
• The heater must be operated for 10 minutes at least once
a year, with the engine cold and the fan set to the
minimum setting.
• The heater must be inspected every 2 years by a specialist
at the beginning of the heating season or earlier.

Normal operation
The heater can be started via the heater control, depending on its configuration. Before park-
ing the vehicle, the settings required for the model must be carried out (temperature, fan).
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.
It is recommended that you have the vehicle maintained and checked at regular intervals by
an authorised Webasto dealer.
All repair or maintenance work must always be carried out by your authorised Webasto deal-
er. The dealer can also help with the specification of the required maintenance.
Warning
A great deal of repair and maintenance work performed on the heater requires spe-
cialised knowledge and special tools. Incorrect settings and maintenance can lead to
damage to the heater or accidents resulting in serious damage.
• For optimum performance, your authorised Webasto dealer should check and perform the
necessary maintenance work on the heating system at least every 2 years regardless of use.
• The heater must be switched off prior to cleaning.
• The heater may NOT be cleaned with high-pressure cleaning systems or compressed air.
Liability:
• Non-compliance with the operating 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/ECE type permit.

Action in the event of faults
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; no error is indicated on the
heater control.
Always try to cancel the fault interlock before calling a Webasto service centre.
The following faults can be remedied directly by the user:
