Location selection

After installation of the air-conditioning system, any ex-
isting exhaust cowl nearby must extend at least 10 cm
over the air-conditioning system. The exhaust cowl must be
extended if necessary (pay attention to the heater manufactur-
er's information).
The vehicle roof (roof thicknesses from 25 to 110 mm) must
be level and smooth.
There are 3 installation options:
– A new cut-out has to be made (350 x 380 mm).
– Cut-out from an existing skylight (400 x 400 mm) without
sealing frame (accessories).
– Cut-out from an existing skylight (400 x 400 mm) with seal-
ing frame (accessories) (Operating instructions are supplied
with the sealing frame.)
Please always take the following requirements into
account:
– If at all possible, the unit should only be installed a little way
from the centre of the vehicle.
– Check that installation will not be obstructed in any way.
– There may be electrical cables running between the inside
and the outside of the roof. Disconnect all voltage sources
before starting work (all poles).
– The maximum permitted roof load must not be exceeded
(see the vehicle manufacturer's specification).
– Check the internal installation location for obstructions.
– A wooden reinforcement frame must be fitted around
the cut-out in the roof between the upper and lower roof
surface (min. 25 mm). It may be necessary to remove the
insulation.

Installation in a 400 x 400 cut-out

For optimum sealing, we recommend using the sealing frame
which can be purchased as an accessory (part no. 40091-19000).
Installation with the sealing frame is described in the installa-
tion instructions supplied with it.
Installation of the unit in vehicles with an existing skylight:
The cut-out must measure 400 x 400 mm.
Remove the existing skylight (increase the size of the cut-out
if necessary).
Remove seal residue and unevenness.
Fill screw holes with body sealant.
For the remaining installation steps, please refer to "Prepara-
tion for mains cable connection".

Installation in a new cut-out

Vehicles without an existing cut-out:
required cut-out 350 x 380 mm
Place the template in the installation location on the vehicle
and mark and cut out the cut-out (350 x 380 mm).
Mark out the 4 holes (10 mm) for attaching the brackets and
drill through the roof.

Preparation for mains cable connection

A leadthrough for the mains cable to the connection point
should be provided in the intermediate ceiling, for example.
Lift the unit onto the roof, holding it in a horizontal position,
and insert it into the cut-out. The arrow points in the vehicle's
direction of travel.
If the unit has been turned over or was not horizontal at
all times, you must wait 2 hours before switching it on.
Slide the unit forward in the cut-out as far as it will go.
Remove the protective film.
