must be observed. The use of the heater in "vehicles for

the transportation of dangerous goods" (ADR) is not

permitted.

The examination is performed by presentation of the

manufacturer’s operating/installation instructions.

The year of first operation must be durably marked by

the installer on the heater identification label by removing

the numerals of the years not applicable.

The heater must not be installed in the passenger or driver

compartments of vehicles.

The heater may only be installed in vehicles or

independent heating systems with a minimum coolant

capacity of 4 litres.

When checking the cooling water level proceed in

accordance with the vehicle manufacturer's instructions.

The water in the heating circuit of the heater must contain

at least 10 % of a quality brand anti-freeze.

Extracting combustion air from the vehicle interior is

prohibited.

The exhaust line outlet is to point downwards or to the

side, or in case of exhaust venting below the vehicle floor,

to be located at the nearest possible location of the

vehicle's or cockpit side or rear end.

Exhaust lines must be routed so that exhaust fumes are

unlikely to penetrate into the vehicle's interior. The

function of any part of the vehicle essential for operation

must not be impaired. Accumulations of condensate in the

exhaust line must be directly drained. A drain hole may be

provided as required.

The openings of the combustion air inlet and the exhaust

outlet must not allow a ball of 16 mm in diameter to be

inserted.

Electrical lines and switching gear of the heater must be

located in the vehicle so that their proper function cannot

be impaired under normal operating conditions.

For the routing of fuel lines and the installation of

additional fuel tanks §§ 45 and 46 of the StVZO are to be

adhered to. The most important regulations are:

• fuel lines are to be designed in such a way that they

remain unaffected by torsional stresses in the vehicle,

engine movement, and the like. They must be

protected against mechanical damage. Fuel-carrying

parts are to be protected against excessive heat and

are to be arranged so that any dripping or evaporating

fuel can neither accumulate nor be ignited by hot

components or electrical equipment.

• the heater must not be located in rooms

accommodating persons.

• the heater mode of operation – at least "on" or "off" –

must be clearly visible.

1.4.2 General Safety Notes

At filling stations and fuel depots the heater must be

switched off as there is a potential danger of explosion.

Due to the danger of poisoning and suffocation the heater

must not be operated, not even with timer or under remote

radio control (Telestart), in enclosed areas such as

garages or workshops not equipped with an exhaust

venting facility.

In the vicinity of the heater a temperature of 120° C

(storage temperature) must not be exceeded under any

circumstances (e.g. during body paint work). Excessive

temperatures may cause permanent damage to the

electronics.

All fuel lines must have leak-proof connections, must

show no damage and must be checked in regular intervals

(at least to the same schedule as the vehicle itself).

Should damage or leakage be detected, it is not permitted

to continue heater operation until the damage has been

rectified by an authorized Webasto repair shop.

NOTE

Make heater inoperative by removing fuse. The fuel lines

(Mecanyl hoses) must not come into direct contact with

exhaust pipe and must be thermally insulated to prevent

fires.

Non-compliance with the installation instructions will void

the Webasto warranty. The same applies for unskilled

repairs or repairs not using original spare parts. This will

also void the general marks of conformity of the heater

and thus the vehicle’s permit of operation.

Before first operation make sure to read the heater

operating instructions.
