ing the period that the work is carried out. The ventilation should safely disperse any re-
leased 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, fluores-
cent 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 dam-
aged.
• 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 50 cm must be kept.

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 instal-
lation 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 longitu-
dinal 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
