13

EN 
• The electrical power supply must be connected by a qualified electrician who has demonstrated
skill and knowledge related to the construction and operation of electrical equipment and installa-
tions and has received safety training to identify and avoid the hazards involved.
• Disconnect all power supplies when working on the ventilation system.
• Ensure that the appliance cannot be reconnected.
WARNING! Electrocution hazard
• The appliance shall be installed in accordance with national wiring regulations.
• 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.
CAUTION! Beware of injury
• Improper installation of the ventilation system can result in irreparable damage to the appliance and
put the safety of the user at risk.
• Always have someone to help you carrying or lifting the ventilation system.
• 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
• 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.
• Observe the structural strength of the roof of the vehicle. The roof of the vehicle must be able to
bear the weight of the ventilation system without being indented or deformed. In doubt consult the
vehicle manufacturer.
Choosing the way of installing the ventilation system
Choose your way of installing the ventilation system:
