• 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 dometic.com/dealer).
• 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. 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.
• Ensure that the working area is in the open or that it is adequately ventilated before breaking into the system or conducting any hot work. A degree of ventilation shall continue during the period that the work is carried out. The ventilation should safely disperse any released refrigerant and preferably expel it externally into the atmosphere.
• Under no circumstances shall potential source of ignition be used in the searching for or detection of refrigerant leaks. A halide torch or any other detector using naked flame shall not be used. Electronic leak detector or leak detection fluids (eg. Bubble method, fluorescent method agents) can be used to detect refrigerant leaks. If a leak is suspected, all naked flames shall be removed/extinguished. If a leakage of refrigerant is found which requires brazing, all of the refrigerant shall be recovered from the system or isolated in a part of the system remote from the leak.
• Do not pierce or burn the appliance.
• Be aware that refrigerants may not contain an odor.
• The roof air conditioner shall be installed in a vehicle with a floor area larger than 4 m².

⚠ CAUTION! Failure to obey these cautions could result in minor or moderate injury.

• Only operate the appliance if you are certain that the housing and the cables are not damaged.

• Ensure that no combustible objects are stored or installed near the air outlet. A distance of at least 50 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 roof air conditioner when the vehicle is in motion.
• Ensure the roof frame is sealed appropriately to the roof.
• Select a flat and sufficiently level area at the center of the vehicle roof between two longitudinal sections for installation.
• The roof inclination of the installation surface may not exceed 10 °.
• Ensure that there are no objects within the vehicle which could obstruct the attachment of the air distribution box or the cooled air from flowing through the swivelling air distribution nozzles.
• Do not make any alterations or conversions to the appliance.
• Never drive through automatic car washes when the appliance is mounted.
• If faults occur in the refrigerant circuit, the system must be checked by a specialist company and repaired properly.
• The refrigerant must not be released into the air.
• Ask the vehicle manufacturer if the height entered in your vehicle documents needs to be altered due to the installation of the roof air conditioner.
• When breaking into the refrigerant circuit to make repairs or for any other purpose eg. Remove refrigerant or open the circuit by cutting or brazing, follow the working procedure as indicated in service manual.
• If charging refrigerant is needed, follow the charging procedure as indicated in service manual.

• 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.
• 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.
• After the installation of the roof air conditioner, an exhaust chimney in proximity to the roof air conditioner has to rise at least 10 cm above it. If necessary, prolong the exhaust chimney. Observe the instructions 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 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 aging 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.
