Webasto Air Top 3500 ST Installation Instructions Manual - page 6
If installed in the vehicle’s interior, the lead-through open-
ings for combustion air inlet, exhaust gas outlet and fuel
pipe must be splash-water protected.
For this purpose, the special gasket supplied with the
heater must be used (see Fig. 4).
The gasket must be
renewed prior to each re-installation.
Mounting the Heater
When mounting the Air Top 3500/5000 heater, the M 6 nuts
must be tightened to a torque of 6 Nm +1 Nm.
The mounting dimensions as well as the space required
for the performance of servicing work are shown in the in-
stallation drawing (Fig. 1). The specified horizontal and
axial angles of inclination must not be exceeded (Fig. 2).
A gasket (Fig. 4) must be fitted between heater and car
body.
The gasket must be renewed prior to each re-
installation. The support surface for the heater mounting
foot
must be level. A special tool is available from the
manufacturer for drilling the holes and levelling the support
surface, if necessary. Surface irregularities of up to
max. 1
mm can be compensated for by means of the gasket.
CAUTION:
After the installation has been performed, a check must be
carried out to verify that no part of the housing is in contact
with any surrounding parts. Non-compliance could result in
a blockage of the heater fan.
Name Plate
The type plate must be located at a place where it is pro-
tected against damage and be easily accessible once the
heater has been installed (or else, a type plate duplicate is
to be used).
The years not applicable are to be removed from the type
plate.
