Intended use

This device has been designed for installation in motor homes
and caravans and is intended for use in the private sector.
Other applications are only permitted after prior consultation
with Truma.

Selecting a location

After the roof air conditioning system has been in-
stalled, any exhaust cowl that is in the vicinity must
protrude at least 10 cm over the air conditioning system.
The exhaust cowl must be extended if necessary (pay atten-
tion to the heater manufacturer's specifications).
The roof of the vehicle (roof thicknesses of 25 to 110 mm)
must be level and smooth.
Three installation options are available:
– The cut-out must be a new cut-out (350 x 380 mm)
– Cut-out of an existing roof hatch (400 x 400 mm) without a
sealing frame (accessory).
– Cut-out of an existing roof hatch (400 x 400 mm) with a
sealing frame (accessory). The installation instructions are
included with the sealing frame.
Attention must always be paid to the following points:
– The device should be installed as close as possible to the
centre of the vehicle.
– Check that no obstructions are present that will hinder
installation.
– There may be electrical cables running between the interior
and the exterior of the roof. Disconnect all voltage sources
before starting the work (all poles).
– The roof load must not be exceeded (see vehicle manufac-
turer's specifications).
– Check interior installation site for obstructions.
– A wooden reinforcing frame (min. 25 mm) must be installed
around the roof cut-out between the upper and lower sur-
faces of the roof. The insulation may have to be removed.
When the skylight with safety ventilation is replaced by
the air conditioning system, it must be ensured that the
safety ventilation is restored in another suitable location.
