In the event of prolonged smoke accumulation, unusual com-
bustion noise or smell of fuel, the heater must be shut down
by removing the fuse and must not be started again until it
has been examined by Webasto-trained personnel. Liability
claims can only be asserted for proven compliance with the
maintenance and safety information by the claimant.
Installation regulations for Webasto fuel tanks for supplying
fuel to heaters in vehicles:
•
The tanks must not be installed in the passenger's
compartment or driver's cab of busses.
•
The fuel filler neck must not be inside the passenger's
compartment or driver's cab in any vehicle.
•
Petrol fuel tanks must not be installed directly behind the
front panelling of the vehicle. They must be separated
from the engine in such a way that in the event of an
accident the fuel cannot ignite. This does not apply to
tractor units with an open driver's seat.
Due to the potential fire risk, the fuel lines (Mecanyl hose)
must not make direct contact with the exhaust pipe and must
be thermally insulated wherever necessary.
All fuel pipes must have sealed connections, they must not be
damaged in any way and must be checked at regular intervals
(at least at the same intervals as the vehicle inspection).
NOTE
If any damage or leaks are found on the fuel line, the heater
must not be used until the damage has been rectified by an
authorised Webasto workshop.
Put the heater out of action by removing the fuse.
Overheating
Keep the heating air inlet and heating air outlet free of dirt
and foreign objects. Dirty, blocked air lines can cause the
heater to shut down due to overheating.
After the heater has shut down due to overheating, check
that the air system is clear, remove any materials that may
block the air flow and have any damage to the air lines
repaired by an authorised Webasto workshop. The heater
lock-out can then be cancelled by switching the heater off
and on again. If this action does not produce the required
success (if the heater overheats again), take it to a Webasto
authorised workshop. Never remove the grill over the air inlet
of the heater.
The air outlet jets or air vents with adjustable flaps must
always be opened by a certain extent so that the air flow
through the heater is not completely blocked. At least one air
vent must be unclosable.
If the heater is installed in a storage area you must ensure
that no flammable substances are kept in this area and that
other material does not restrict the air supply to the heater.
Air lines must be securely fixed to the heater (pipe clips) and
all other connection points (vents).
ATTENTION
The points described below must be avoided:
•
Do not step on the heater and do not place or throw any
heavy objects onto the heater.
•
Do not place any items of clothing, fabrics or similar
materials over the heater or in front of the heating air
intake side and the heating air outlet.
•
The flow of hot air from the heater must not be restricted
or blocked by highly flammable substances or materials
such as rags, cleaning wool etc.
•
Flammable or explosive substances and gasses must not
be placed near or in contact with the heater, the hot air
line, the hot air flow or the exhaust pipe.
•
The heater must not be cleaned with a high-pressure
cleaner.
•
Do not frequently switch off the heater at the main
battery switch or battery disconnector otherwise the
heater may suffer long-term damage and malfunctions.
NOTE
Failure to follow the installation instructions and the notes
contained therein will lead to all liability being refused by
Webasto.
The same applies if repairs are carried out incorrectly or with
the use of parts other than genuine spare parts. This will
result in the invalidation of the type approval for the heater
and therefore of its homologation / EC type licence.
Carefully read the operating instructions before operating the
heater.
