When using a receiver that has been installed separately into the ceiling, use the enclosed
fi ttings for installing to a ceiling.
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 × 51 mm)
3. Pass the wiring through the enclosed installation metal fi tting and put it into the hole. (Fig. A)
4. Bend parts A and B of the metal fi tting so they hold onto the ceiling fi rmly. (Fig. B)
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 × 40)
7. Bend parts A and B back so they fi t 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. C)
8. Attach the face plate.

1. Strip the wire to be connected of its sheathing for 14 mm.
2. Twist the two wires together and crimp the enclosed wire joint.
3. If a special crimping tool is not used, or if the connection is made using solder,
wrap the joint with insulating tape.
