General Information
Dear Webasto Customer !
We assume that the workshop / service center that carried out the installion explained to
you the operation and principle of functioning of your new heater to your complete
satisfaction. With these operating instructions we would like to provide you with an
overview of the use of the Thermo 90 / 90 S.
Maintenance and Safety Information
Within the scope of the StVZO (Road Traffic Licensing Act) "General Design Approvals"
laid down by the Federal Office for Motor Traffic exist for the Thermo 90 / 90 S water
heaters.
The installation of the units must be carried out in accordance with the enclosed
installation instructions. The installation must be checked in accordance with the Legal
Provisions for Installation. For details refer to the installation instructions.
The year of the initial operation must be durably marked on the heater's nameplate by
removing the non-applicable years.
When installing the Thermo 90 / 90 S D heater in vehicles for the transport of hazardous
materials, the requirements laid down in ADR 002 and ADR 003 (Technical Guidelines
relating to the ordinance of transporting hazardous materials on the road) must be
fulfilled in addition to those of the StVZO.
The heater must be switched off :
n at filling stations and tank farms.
n in locations where flammable vapours or dust may
!
accumulate (e.g. in the vicinity of fuel-, coal-, sawdust or
grain depots).
n in enclosed spaces (e.g. garages). This should also be

and asphyxiation
using the Telestart remote control.
The heater must not be
D
n exposed to temperatures greater than 120°C (storage
temperature). Exposure to such temperatures may cause
damage to the electronic components.
n operated without a minimum level of 20% of good quality
antifreeze in the water of the heating circuit.
The heater must :
n be operated with the fuel specified on the namplate.
n In the case of a severe build-up of smoke, unusual

combustion noises or fuel smell, the heater is to be put out
of operation by removing the fuse and may only be
restarted after it was inspected by Webasto-trained
personnel.
n be operated at least once a month for 10 minutes, with the
vehicle engine cold and at the lowest fan setting. The
heater should be checked annually by a qualified expert,
preferably prior to the heating season commencing.
Liability claims:
n Webasto will not assume any liability if the installation
instructions and the notes contained therein are not
observed. The same applies to improperly performed
repairs or those where others than genuine replacement
parts have been used. In those cases, the heater's General
Design Certification and thus the General Operating Permit
(homologation) will be invalidated as a consequence.
n Claims can only be asserted if the claimant can prove that
the maintenance and safety notes were adhered to.
Operation
Before switching the heater on, set the vehicle heating system to the "warm" position
and the vehicle heater fan to the lowest setting (less power consumption)!
Applicable to Thermo 90 / 90 S -ADR only: The heater is switched on by means of the
switch. A ADR situation (forced shut-down) is initiated when
- the vehicle engine is switched off
- a pumping device is put into operation,
in which case the short after-run period is terminated after 20 seconds.
Thereafter, the electronic control unit is in the "fault lock-out" state. Before the heater can
be restarted, the On/Off switch must be set to "Off".
The disconnect switch (Emergency Stop switch) may only be actuated in an emergency
situation since this will shut the heater down without any after-run being performed
(danger of overheating).
