• Keep all operation and maintenance manuals carefully and

deliver them to the next owner when the unit is passed on.

• Check that all current national safety code requirements have

been followed for the installation.
In particular ensure that a properly sized and connected

• For correct use, the air conditioner must operate within the

temperature limits indicated in the table “Operating limits”
included in the outdoor unit installation manual.
Incorrect use of the unit outside these limits results in

handling: In case of damage file an immediate claim with the
shipping company.

• Maintenance of the refrigerant circuit must only be carried out by

qualified personnel.

The unit must then be delivered to an appropriate disposal
centre or to the original equipment dealer, for proper environ-
mentally-friendly disposal.

• Remote control batteries contain polluting elements.

When exhausted, they must be disposed of in accordance with
local requirements.
