Fixing
●Temporarily secure the 2 screws with washers 2, and
also the other 2 screws with washers 2, and then tighten
these screws with washers 2 after making sure that the position
of Multi-functional casement 1 is correct.
●Be sure to do the wiring (indoor/outdoor unit connection cable,
remote controller cable, etc.) before installing the Multi-functional
casement 1:
Note: Wiring after installing the Multi-functional casement 1 will be difficult.

Temporarily secure the 4 screws with washers.
●Tightening the screws without temporarily securing
them could damage the screws with washers, or
cause air leakage.
