In the case of M2 and M3 vehicles, the combustion heater must not be positioned in the passenger compartment.
However, an installation in an effectively sealed envelope which also complies with the conditions in paragraph
5.3.2.2 may be used. (Requirement from ECE-R 122, Point 5.3.2.3.).
The installation box must have sufficient external ventilation to ensure that a maximum temperature of 40°C is not
exceeded in the box. Malfunctions may occur if the temperature exceeds this level.
The heater must be switched off at filling stations and tank farms as a result of the risk of explosion.
Wherever inflammable vapors or dust may form (for example in the vicinity of fuel, carbon, wood dust or grain mill (or
the like), the heater must be switched off as a result of the risk of explosion.
The heater must not be operated in enclosed areas such as garages and workshops without an emissions extraction
system, even if you use the timer, because of the risk of asphyxiation and poisoning.
In case of longer-lasting smoke emission, unusual combustion noises or fuel odors, the heater must be shut down by
removing the fuse and may not be returned to operation again until after it has been checked by personnel trained by
Webasto. Claims can only be made if it can be verified that the claimant has complied with the servicing and safety
instructions.
The fuel lines may not make direct contact with the exhaust pipe and must be thermally insulated if necessary, as
otherwise there is a fire danger.
All fuel-carrying lines must be connected leak-tight, may not be damaged and must be inspected regularly (at least at
the same interval as the vehicle inspection).
NOTE:
If damage to or leaks in the fuel line are determined, the heater may not be operated until the damage has
been eliminated by an authorized Webasto specialist workshop. Put the heater out of action by removing the fuse.
Overheating
Keep the cold air inlet and hot air outlet free of dirt and objects. Blocked air lines can result in an overheating switch-
off. After an overheating switch-off, the air routing must be checked for free passage and all materials which impair
the flow of air must be removed or damage to the air routing must be repaired by an authorized Webasto specialist
workshop.
Never remove the grille in front of the cold air inlet.
The fault lock-out must be eliminated by switching the heater off and then on again. If these measures are
unsuccessful (overheating occurs again), the vehicle must be taken to an authorized Webasto specialized workshop.
The air outlet jets or air vents with adjustable flaps must always be opened to some extent so that the air current
through the heater is not completely blocked. At least one air outlet must be non-closable.
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 firmly secured on the heater and at all other connection points (e.g. air outlets) (e.g. with pipe
clamps).
