Installation
Note on electrical system
 Only a qualified electrician should connect the roof air conditioner to the
electrical power.
 Check that the voltage specification on the type plate is the same as that
of the power supply.
 If the lighting should also be switched on without a 230 V voltage supply,
make sure that there is a 12 Vg power supply line from the battery to the
roof air conditioner.
 Do not lay the 230 V mains cable and the 12/24 Vg cable together in the
same cable duct.
 Do not lay cables which are loose or bent next to electrically conductive
material (metal).
 Install an all-pole switch with a contact opening width of at least 3 mm on
the installation side.
There are two ways of installing the roof air conditioner:
 Making a new opening (chapter "Making a new opening" on page 34). In
this case the opening must be reinforced by an appropriate frame.
 Using the existing roof hatch openings (ventilation hatch) in the vehicle
(chapter "Installing in a roof hatch opening already provided" on page 35).
8.2 Making a new opening
See fig. 3
➤ Select an area at the centre on the roof between two longitudinal sup-
ports.
➤ Mark the position and size of the opening using the template included in
the packaging (A and B).
See fig. 4
➤ Drill out the corners (A).
➤ Carefully cut out the opening on the roof using a keyhole saw or a similar
tool (B).
Make sure no electrical power cables are damaged.
See fig. 5
➤ Before installation, check whether the roof hole needs reinforcing.
➤ Remove the foam according to the width of your reinforcing rails (not in
scope of delivery) (A).
➤ Fit the reinforcing rails (B).
