1  Open the air inlet grill on the side panel. Remove the 1 screw and move it toward the front  

(in the direction of an arrow) to remove it. (Fig. A)

2  Wrap the tip of a slotted screwdriver with plastic tape and then insert it under the O-marked 

surface of the cover, wiggling the cover free. (Fig. B) (Be careful not to scratch the panel.)

3  After passing the lead wire through the panel, install the receiver in the hole in the panel.  

(The projecting parts of the receiver is held in the hole in the panel.)

4  Fasten the receiver’s lead wire to the cable clip that is holding the wire from the louver motor.  

(Fig. C)

5  Attach the side panel. 

6  Put the receiver’s lead wire together with other wires such as the louver motor wire, and fasten 

them with the cable clip. (Fig. D)

 Use the hole in the upper part of the wiring box to lead it in.

 For more information about wiring and test runs, see the sections on “Wiring for the Receiver” and  

“Test Operation”.

Installation Location for the Reciver 

 

The wireless remote controllers use a very weak infrared light for its signal, which can result in the signal 

not being received because of the following influences, so take care in where the unit is installed.

 

Inverter or rapid-start type fluorescent lights (Models without glow lamps)

 

Plasma display or LCD televisions

 

Direct sunlight or other sources of bright light

Attention

  Multiple wireless remote controllers cannot be used simultaneously for a single indoor unit.

 

Be careful not to connect cables to other terminals of indoor units (e.g. power source wiring terminal). 

Malfunction may occur.

 

Do not bundle together with the power source wiring or store in the same metal tube. Operation error may 

occur.

 

If noise is induced to the unit power supply, attach a noise filter.

Installation when setting Main/Sub for the remote controller and the receiver

After installation, according to the “Settings” section, set one to [Main] and the other to [Sub].

Setting the wired remote controller to [Main] is recommended.

The remote controller and the receiver can be connected to any indoor unit for operation.
