Installation
7.2.4 Installing the roof air conditioner
I Note
Make sure the roof air conditioner is centred perfectly. Apply a flexible
non-hardening butyl sealing compound (e.g. Sika Lastomer-710) to the
seal before inserting it. The seal must be applied continuously around the
roof air conditioner after placing it on the roof of the vehicle. This is the
only way to ensure a tight seal.
Lift the roof air conditioner onto the roof of the vehicle.
Observe the direction of travel (arrow, fig. 1, page 2).
a Caution – risk of damage
Observe the structural strength of the roof of the vehicle. The roof of the
vehicle must be able to bear the weight of the device. The roof must not
be indented or deformed by the weight of the device, even over a longer
period of time.
Note
I
The roof of the vehicle can be reinforced (e.g. with a wooden frame) if the
load-bearing capacity of the roof is insufficient.
Position the roof air conditioner over the installation opening.
Observe the direction of travel.
7.2.5 Fastening the system (fig. 8, page 4)
Install the attachment frame using the fastening screws (4 x M8 x 100
hexagon bolts) and the U washer (4 x M8) which belong to the scope
of delivery.
Note
I
The supplied hexagon bolts (4 x M8 x 100 mm) can be used for up to
70 mm thick roofs. Hexagon bolts (quality class 8.8) which are appropri-
ately longer must be used for other roof thicknesses.
a Caution – risk of damage
Tighten to the specified torque.
Tighten the screws using a torque wrench and a fastening torque of
(3 Nm) 0.3 kg/m.
