2 Unit installation
Air panel installation
Hang the air panel from the indoor unit, attaching the cables in a
U-shape from the panel to the unit hook cables.
Check that the position of the electrical junction box on the indoor
unit coincides with the position of the air panel wiring outlet.
Position the panel on the indoor unit and secure using the long
screws supplied.

• To avoid damaging the panel, the long screws securing it
are fitted with stops to stop tightening at the set position.
• Where the air panel does not reach the ceiling surface or
in the event of air leaks on the touching surface, readjust
the installation height of the indoor unit.
Check that there are no gaps in the touching surface between the indoor unit and the air panel. Gaps may cause air leaks
or condensation.
