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 air conditioner:
• Making a new opening (chapter “Making a new opening” on page 11). 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 12).
8.2 Making a new opening
See fig. 3
➤ Select an area at the centre on the roof between two longitudinal supports.
➤ Mark the position and size of the opening using the template included in the
packaging (A and B).
Alternatively, you could create two small openings (C).
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.
