3.1. Air Top 2000 ST installation situation
NOTE:
Check the installation situation of the relevant vehicle type.
3.2. Installation location
The heater may be fitted both in the interior or on the exterior of the vehi-
cle.
When using the vehicle in normal road traffic, the heater may only be in-
stalled with contact protection if it is located within reach of the driver.
If it is installed on the exterior ensure that the heater is fitted in a position
where it is protected from splashing water and spray.
The heater must be installed in such a way that no water can ingress into
it if the vehicle travels through a water hazard for which that vehicle is li-
censed.
The openings for the combustion air inlet port, the exhaust outlet port and
the fuel pipe must be sealed if the heater is installed in the interior. The seal
designed and supplied for this purpose must be used (see Figure 3).
3.3. To install the heater
The M6 nuts must be tightened with a torque of 6 Nm +1 Nm for installing

The installation dimensions and space requirement for service access are
shown in the installation drawing (Figure 1). The specified horizontal and
axial angles must not be exceeded (Figure 2).
A seal (Figure 3) must be fitted between the heater and the vehicle body.
This seal must be replaced each time the heater is installed. The sup-
port area for the heater foot must be flat. A special tools can be pur-
chased from Webasto to drill the holes and, if necessary, smooth the sup-
port area. The seal can compensate for unevenness of max. 1 mm.
IMPORTANT
After installation, check that the casing is not in contact with any parts of
the vehicle body. A failure to do this may result in the hot air fan blocking.
