4. Use bracket parts (A) and (B) to securely grip the ceiling 

material. (Fig. E)

5. Connect the Signal receiving unit wire (2-core) to the wire 

from the indoor unit. (Refer to “Wiring the Signal receiving 
unit.”) Check the terminal number on the indoor unit 
before wiring the Signal receiving unit and be sure not to 
wire incorrectly. (The unit will be damaged if high voltage, 
such as 208/230 VAC, is applied.)

6. Adjust the provided spacers so that they are several 

millimeters larger than the thickness of the ceiling 
material. Pass the 2 supplied screws (0.16” x 1.6” (M4 x 
40 mm)) through the spacers and tighten them enough to 
hold the Signal receiving unit in place.

7. Return parts (A) and (B) through the gap between the 

ceiling and Signal receiving unit so that they are 
contained in the openings. Then tighten the screws.
Do not tighten the screws excessively. This may result in 
damage or deformation of the case.
Tighten to the point where the Signal receiving unit can be 
moved slightly by hand. (Fig. F)

8. Reattach the face plate.
