AIR CONDITIONING

AIR CONDITIONING (optional)

The air conditioning system components require regular servicing. Respect these service intervals to ensure the correct operation and full effectiveness of the air conditioning system. The air conditioning system contains a gas which is subject to strict regulations. Any failures in the system must be repaired as quickly as possible.

WARNING: Never perform any service work on the air conditioning circuit. Consult an approved specialist for any service work required.

NOTE: Use the air conditioning at least once a week, if only for a short time. See “Air conditioning controls” in the “Controls/Instruments/Accessories” Section.
