• Always wear the recommended protective clothing (e.g. protective goggles, gloves).

NOTICE! Damage hazard

• Observe the structural engineering of the vehicle and seal of all openings made when installing the roof air conditioner.
• Check whether the roof of the vehicle is able to support the weight of a person before climbing onto it. Ask the vehicle manufacturer about the permissible roof loads.

Note on transport

• Always have someone help you carry the roof air conditioner.
• Always lift the roof air conditioner to move it and never drag it over the roof
• Do not use the rear ventilation slots to lift it .

Note on installation location

• Before installing the roof air conditioner, check whether any vehicle components could be damaged by the installation of the roof air conditioner (such as lamps, cupboards, doors).
• Before installation, find out (by consulting the manufacturer of the vehicle) whether the construction is designed for the static weight and the loads of the air conditioner when the vehicle is in motion. The manufacturer of the roof air conditioner assumes no liability whatsoever.
• The vehicle manufacturer may have already provided points where the opening for the installation of the roof air conditioner can be made without any risk of weakening the construction or cutting power cables.
• Select a flat and sufficiently level area at the centre of the vehicle roof between two longitudinal sections for installation.
• The roof inclination of the installation surface may not exceed 10°.
• The roof air conditioner must be installed above 2 meters.
• Make sure no combustible objects are stored or installed near the air outlet. A distance of at least 50 cm should be kept.
• 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 swivelling air distribution nozzles.

• The device shall be installed, operated and stored in a room with a floor larger than 4 m2.

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.
• If the appliance is powered by the mains, ensure that the 230 V voltage supply has a residual current circuit breaker.
• Make sure that the grounding cable of the air conditioner is connected to the vehicle‘s grounding system.

There are two ways of installing the roof 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 11).

Making a new opening

• 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).
• 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).
• Drill out the corners (A).
