In case of faults, please check the following
points
• If the heater does not start after being switched on:
– Switch the heater off and on again.
• If the heater still does not start, check whether:
– There is fuel in the tank?
– The fuses are OK?
– The electrical cables, connections etc. are OK?
– Anything is clogging the combustion air supply
or exhaust system?
Troubleshooting
If the heater remains faulty even after these points
have been checked, or another malfunction occurs
in your heater, please contact:
• For installation ex works, your contract workshop.
• For subsequent installation, the workshop who
installed your heater.
Please note that warranty claims can be become void
if the heater is changed by a third party or by this
installation of third party parts.
Maintenance instructions
• Before the heating period starts, the heater should
undergo a trial run. If persistent extreme smoke
develops, unusual burning noises or a clear fuel
smell can be perceived or if electric / electronic
parts heat up, the heater must be switched off and
put out of service by removing the fuse.
In this case, the heater should not be started up
again until it has been checked by qualified staff
who have been trained on Eberspächer heaters.
• Check the openings of the combustion air supply
and exhaust system after longer standstill periods,
clean if necessary!
