Installation
• Make sure that there are no objects within the vehicle which could obstruct the
attachment of the air outlet unit or the cooled air from flowing through the swiv-
elling air distribution nozzles.
• For safety reasons, note the location of existing wiring harnesses, wires and other
components within the installation area, in particular those which are not visible,
when installing the roof air conditioner (when drilling or screwing etc.).
Note on electrical system
• Only a qualified electrician should connect the roof air conditioner to the electri-
cal power.
• Check that the voltage specification on the type plate is the same as that of the
power supply.
• 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.
8.2 Making a new opening
See fig. 5
➤ Select an area at the centre on the roof between two longitudinal supports (1).
➤ Mark a 362 mm x 362 mm (± 3.2 mm) square on the roof.
➤ Drill out the corners.
➤ Carefully cut out the opening on the roof using a keyhole saw or a similar tool.
Make sure no electrical power cables are damaged.
➤ 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).
➤ Fit the reinforcing rails of at least 25 mm thickness (2).
➤ Remember to provide an entrance hole for power supplies at the front of the
opening.
Make sure that at least 375 mm of supply wire extends into the roof opening.
This ensures an easy connection at the junction box (3).
