Maintenance and Safety Instructions
1. Webasto heaters must be switched “off” when re-fueling at filling stations to prevent the risk of
explosion. Please review the owner’s manual for safety and use instructions.
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 heater must not be operated without at least 20% brand name anti-freeze in the water of the heating
circuit.
4. The heaters are not designed for heating hazardous substance transport compartments.
5. Claims can only be made if it can be verified that the claimant has complied with the servicing and safety
instructions.
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 is used.
7. 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.

Heater Lockout Procedure
The control unit continuously monitors the heater operation. The control unit identifies errors on
individual heater components and faults during operation. Should the control unit experience component
errors and operational faults, the heater may be shut down.
Causes:
The heater is shut down (fault lock-out) if:
– No or incorrect start
– Temperature sensor defective
– Overheating sensor interrupt or short circuit
– Overheating sensor installed incorrectly
– Ceramic glow pin interrupt or short circuit
– Fan motor overload or blocked or short circuit or interrupt
– Error in the fuel metering pump or circuit
– Under voltage or over voltage for longer than 20 seconds.
– Control unit defective
– Overheating
Effects:
The fuel supply is stopped if the heater overheats.
The heater continues to run in the same way as if it is switched off manually.
After the heater stops the control unit may set in fault lock-out mode.
Heater Lock out Reset Procedure:
1. Using switch or standard timer control, turn heater on
2. Remove the main power connection to heater from battery or pull fuse for a minimum of 20 seconds.
3. Using switch or standard timer control, turn the heater off.
4. Reinstall main heater power connection where previously disconnected.
Rectify the cause of the fault.
IMPORTANT: Heater fault codes can be read using PC Diagnostics, however, the heater lockout reset must
be manually performed using the procedure stated above.
