Part A
Part B
(1) Remove the metal plate of the receiver by slipping a slotted screwdriver or the like into the cutout on the bottom.
(2) Cut out a hole in the ceiling to match the dimensions of the enclosed template. (95 X 51 mm)
(3) Pass the wiring through the enclosed installation metal fitting and put it into the hole. (Fig. 8-29)
(4) Bend parts A and B of the metal fitting so they hold onto the ceiling firmly. (Fig. 8-30)
(5) Connect the receiver’s wiring (2 cores) with the wiring from the indoor unit. (Refer to the chapter on wiring the receiver)
When wiring receivers, be sure to double-check the terminal numbers of the indoor unit before connecting them so
there are no mistakes in the wiring. (Damage will occur if high voltage [e.g. supply voltage] is applied)
(6) Adjust the enclosed spacers so they are several millimeters thicker than the ceiling material and hold the receiver in place
temporarily with the 2 enclosed small screws. (M4 X 40)
(7) Bend parts A and B back so they fit in the opening and are in the gap between the surface of the ceiling and the receiver;
then tighten the screws. Do not use too much force when tightening the screws. Doing so may warp or damage the case.
Move the receiver by hand and check that it can move just a little. (Fig. 8-31)
(8) Attach the face plate.
