fuse blows out. Use of wire or copper wire may cause the unit to break down or
cause a fire.

It is dangerous to inspect the unit while the fan is running.

NOTICE
Do NOT wipe the controller operation panel with benzine, thinner, chemical dust
cloth, etc. The panel may get discoloured or the coating peeled off. If it is heavily
dirty, soak a cloth in water-diluted neutral detergent, squeeze it well and wipe the
panel clean. Wipe it with another dry cloth.
E.g., at the beginning of the season.
▪ Check and remove everything that might be blocking inlet and outlet vents of
indoor units and outdoor units.

person to clean air filters and casings of the indoor unit. Maintenance tips and
procedures for cleaning are provided in the installation/operation manuals of
dedicated indoor units. Make sure to install cleaned air filters back in the same
position.
▪ Turn on the power at least 6 hours before operating the unit in order to ensure
smoother operation. As soon as the power is turned on, the user interface
