Operating Instructions
BBW 46 / DBW 46
Maintenance and Safety Information
1. Within the scope of the German StVZO (Road Traffic Licensing Act) a "General
Design Certification" has been granted by the Federal Office for Motor Traffic for the
BBW 46 / DWB 46 water heater.
2. Installation of the heater must be performed in accordance with the Installation
Instructions and is to be entered in the certificate of registration. If available, the approval
certificate or the General Design Certification is to be kept in the vehicle.
3. The year of the initial operation must be durably marked on the heater's nameplate by
crossing out the non-applicable years.
4. Claims can only be asserted if the claimant can prove that the maintenance and
safety notes were adhered to.
8. The heater must be inspected by a qualified expert annually, preferably prior to the
heating season commencing.
9. In the case of severe smoke development for an extended period of time, unusual
combustion noises or fuel smell (gas), the heater must be placed out of operation by
removing the fuse and may only be re-started after it was inspected by Webasto-trained
personnel.
10. Only the fuel specified on the nameplate may be used.
11. The heater should not be exposed to temperatures greater than 85°C (storage
temperature). Exposure to such temperatures will cause permanent damage to the
electronics.
12. Checking the cooling water level is to be performed in accordance with the vehicle
manufacturer's instructions. The water in the heater's heating circuit must contain at
least 20% of a good quality antifreeze.
13. 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.
5. Due to the danger of poisoning or asphyxiation the heater must not be operated
in enclosed spaces (e.g. garages or workshops) without adequate exhaust
extraction. This should be considered when pre-setting heater operating times or
using the Telestart remote control.
6. Due to the danger of explosion the heater must be switched off at filling stations
and tank farms.
7. At locations where combustible vapours or dust accumulation can form (e.g. in
the vicinity of fuel, coal, saw-dust and grain depots and so forth) the heater must
be switched off due to the danger of explosion.
Troubleshooting
In the event of a malfunction, fuses and electrical connections should be checked for
condition and security.
In the event of a malfunction, the heater will shut down in its "fault lock-out" mode, no
visual indication will occur on the display of the timer.
Before consulting an authorised Webasto dealer, try to deactivate the fault lock-out
condition by switching the heater off (heater has to remain in the switched-off state for at
least 1 second) and then on again
.If this action does not correct the malfunction, consult your authorised Webasto dealer.

The Webasto radio-controlled TELESTART T60 enables Webasto
BBW 46 / DBW 46 heaters to be switched on and off remotely within
a distance of up to 600 m. After the start-up has been activated by
the transmitter, the heating period is limited by the receiver. Owing to
the pre-programmed duration of the operating time the heater is
switched off automatically. The maximum transmitter range is
attained in unde- veloped areas. In built-up areas the range is likely to
be reduced.
The installer can allocate 2 transmitters to one receiver.
