3 To install the heater
The standard scope of delivery of the heater consists of:
– 1 Heater
– 2 Supports
– 2 Clamping bands
– 2 Turnbuckles
– 1 Intake manifold
– 1 Fuel metering pump
The heater must be installed on a flat surface as shown in Figures 1 and
2. Make the hole pattern as shown in Figure 2.
The floor attachment can be aligned within the specified tolerances by
loosening or tightening the turnbuckles and clamping bands.
The screws of the turnbuckles must be tightened to 5 Nm, the bolts (M8)
of the supports must be tightened to 12 Nm.
The installation dimensions and space requirement for service access
are shown in the installation drawing (Figures 1 and 2). The specified
horizontal and axial angles must not be exceeded.
The heater is not allowed to be installed in the passenger compartment.
If the heater is installed on the exterior, ensure that it is fitted in a position
where it is protected from splashing water and spray.

In the case of installations in which the heater surface could be touched
inadvertently or flammable materials could come into contact with the
heater surface, it is obligatory to mount a shield (Webasto accessory)
over the heat exchanger, see Figure 2. For this purpose, the shield is
clamped between the support and the mounting surface in the vehicle,
see Figure 3. The position must be selected so the return pin on the
temperature sensor can be reached through the cut-out in the shield.
The air heater's heat exchanger can be used for a maximum of 10 years
and must then be replaced by the manufacturer or one of its authorised
workshops using a genuine spare part. A label must then be affixed to
the heater showing the date of sale of the heat exchanger and the
wording "Genuine spare part". If exhaust pipes pass through
compartments used by people, the pipes must also be replaced by
genuine spare parts after 10 years.
