●Route the power wiring into the indoor unit through the power inlet on the side of the unit. At this time, be sure that the wiring passes through the power inlet in the unit power section. If the wiring does not pass through this inlet, it may become pinched by the ceiling panel, and may result in fire.

●Pass the wiring through the power inlet on the electrical component box and connect it to the terminal plate. Then fasten the wiring in place with the clamp.

3-19-1. Before Installing the Ceiling Panel

Checking the position of the indoor unit

(1)Check that the dimensions of the ceiling opening are the following:

28-47/64" ⋅ 23-17/64"

*For details, refer to the installation manual that was supplied with the indoor unit.

(2)Check that the positions of the ceiling surface and indoor unit are as shown in Fig. 3-70. If the positions of the ceiling surface and indoor unit are not correct, problems such as air leakage, water leakage, and flap operation trouble may occur.

●Do not rest the panel facing downwards, lean up against a wall, or leave it sitting on top of a protruding object. Doing so may scratch the panel surface.

●Do not apply excessive force to the flap. (Fig. 3-71) (Doing so may damage the flap.)

Be sure that this distance is within the range of 25/32 – 1 in.

If it is not within this range, malfunction or other problems may result.
