u
Electrical devices are not toys. Keep electrical appli-
ances out of reach of children or the infirm. Persons
whose physical, sensory or mental capabilities are
impaired, or whose lack of experience and know-
ledge prevents them from using the device safely,
should not use the device without supervision or in-
struction by a responsible person.

If faults occur in the air conditioner's refrigerant cir-
cuit, the device must be checked by a specialist
company and properly repaired. The refrigerant
must never be released into the air.

door units of the air conditioner clear.
u
Isolate the power supply if you do not use the air-
conditioner for a long time.

structions in this manual. Incorrect installation meth-
ods or alteration of the product may cause damage

Ask the vehicle manufacturer if a technical inspec-
tion is required after fitting the air conditioner and
whether the height of the vehicle entered in the
vehicle documents needs to be updated.
