DANGER! Electrocution hazard
• The electrical power supply in the RV must be connected by a qualified electrician who has demon-
strated skill and knowledge related to the construction and operation of electrical equipment and
installations and has received safety training to identify and avoid the hazards involved.
• Disconnect all power supplies including inverters when working on the roof air conditioner.
• Ensure that the appliance power supply cannot be reconnected during installation or maintenance.
WARNING! Electrocution hazard
• The appliance shall be installed in accordance with national wiring regulations.
• The following must be incorporated in the fixed wiring in accordance with the wiring rules: An all-
pole disconnection device which has at least 3 mm clearances in all poles; when having a leakage
current that may exceed 10 mA a residual current device (RCD) having a rated residual operating
current not exceeding 30 mA; a disconnection.
• If the appliance replaces a window or hatch with a safety relevant forced venting function, an addi-
tional safety venting device (e.g. a mushroom fan or similar) needs to be added. In doubt consult the
vehicle manufacturer.
• After the installation of the roof air conditioner, an exhaust chimney in proximity to the roof air condi-
tioner has to rise at least 10 cm above it. If necessary, prolong the exhaust chimney. Observe the in-
structions of the heating manufacturer.
CAUTION! Beware of injury
• Improper installation of the roof air conditioner can result in irreparable damage to the appliance
and put the safety of the user at risk.
• Always have someone to help you when carrying or lifting the roof air conditioner.
• Before installation, check the location of existing wiring harnesses, wires, and other components
within the installation area, in particular those which are not visible when installing the appliance
(when drilling or screwing etc.).
• Attach and lay the cables so that they cannot be tripped over or damaged.
• Always wear the protective goggles and gloves.
NOTICE! Damage hazard
• The appliance is a sealed system with a closed refrigerant circuit. Do not open or manipulate, unless
you are an appropriately qualified technician.
• Use cable ducts to lay cables through walls with sharp edges.
• Do not lay loose or bent cables next to electrically conductive materials (metal).
• Do not pull on the cables.
• Check that cabling will not be subject to wear, corrosion, excessive pressure, vibration, sharp edges
or any other adverse environmental effects. The check shall also take into account the effects of ag-
ing or continual vibration from sources such as compressors or fans.
• Observe the structural strength of the roof of the vehicle. The roof of the vehicle must be able to
bear the weight of the roof air conditioner without being indented or deformed. In doubt consult
the vehicle manufacturer.
