WARNING! Failure to obey these warnings could result in death or serious injury.
Repair of the appliance may only be carried out by qualified personnel who are familiar with the risks involved and the relevant regulations. Inadequate repairs may cause serious hazards. For repair service, contact the service center in your country (see epn fujd;dpn -ef bnf s).
EN
The appliance shall be installed in accordance with national electrical and mechanical installation regulations.
Electrical appliances are not toys. Keep electrical appliances out of reach of children or infirm persons. Do not allow them to use electrical appliances without supervision. Persons whose physical, sensory or mental capabilities or whose lack of experience and knowledge prevent them from using the appliance safely should not use it without supervision or instruction by a responsible person. Do not undo the upper cover of the appliance in the event of a fire. Use approved extinguishing agents instead. Do not use water to extinguish fires. The appliance shall be stored in a room without continuously operating open flames (for example an operating gas appliance) and ignition sources (for example an operating electric heater). The appliance shall be stored horizontally at a dry, ventilated and covered location. Do not pierce or burn the appliance.
CAUTION! Failure to obey these cautions could result in minor or moderate injury.
Only start up the appliance if you are certain that the housing and the cables are not damaged. Do not use the appliance near flammable fluids or in closed rooms. Ensure that no combustible objects are stored or installed near the air outlet. A distance of at least 10 cm must be kept. Do not reach into air outlets or insert any foreign objects in the appliance. Always wear protective goggles and gloves.
NOTICE! Damage hazard
The appliance shall be stored so as to prevent mechanical damage from occurring. Before installation, check whether any vehicle components could be damaged by the installation of the appliance (such as lamps, cupboards, doors). The vehicle manufacturer may have already provided points where the opening for the installation of the appliance can be made without any risk of weakening the construction or cutting power cables. Before installation, consult the vehicle manufacturer whether the construction is designed for the static weight and the loads of the ventilation system when the vehicle is in motion.
Seal all openings made when installing the ventilation system. Select a flat and sufficiently level area at the center of the vehicle roof between two longitudinal sections for installation. Ensure that there are no objects within the vehicle which could obstruct the attachment of the air distribution box (ADB) or the fresh air from flowing through the air outlets. Do not make any alterations or conversions to the appliance. Never drive through automatic car washes when the appliance is mounted.

8 Installation
WARNING! Electrocution hazard
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 installations 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 additional safety venting device (e.g. a mushroom fan or similar) needs to be added. In doubt consult the vehicle manufacturer.
CAUTION! Risk 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 help you carry or lift the ventilation system. Before installation, check the location of existing wiring harnesses, wires, and other components within the installation area, especially those that 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 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 vehicle's roof. The roof must be able to bear the weight of the ventilation system without being indented or deformed. If in doubt, consult the vehicle manufacturer.
Choosing the way of installing the ventilation system
NOTE
- Choose a flat and sufficiently level area at the center of the vehicle.
- The roof inclination of the installation surface may not exceed 5°. A downward inclination in the driving direction of up to 15° is possible.
Choose your way of installing the ventilation system:
- Make a new opening (A). In this case, the opening must be reinforced by an appropriate frame.
- Use an existing opening in the vehicle (B) such as a roof hatch or replacing an old device.
EN
Making a new opening
- Select an area at the center of the roof between two longitudinal supports.
- Mark the position and size of the opening.
