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.

1-5. Installing the Receiver
1 While spreading the tabs of the cover, pull it out from the panel to the front. (Fig. A)
2 When installing on the 1-WAY cassette (high-ceiling), pass the lead wire through the panel and
install the receiver in the hole in the panel. (The projecting parts of the receiver are fixed in the
hole in the panel.)
3 Route the lead wire from the receiver along the rib on the back of the panel. Pass it through the
cutout. (Fig. B)
4 Install the panel on the indoor unit.
5 Fasten the lead wire sticking out from the panel with the clamper in the indoor unit. (Fig. C)
6 Draw the lead wire into the electrical box through the hole on the bottom and connect it to the
remote controller terminal board.
When installing to the 1-WAY cassette (high-ceiling), fasten the wire at the latch of the fan
casing with the supplied clamper. (Fig. D)
Fasten the lead wire securely so that it does not get wrapped up in the fan.
For more information about wiring and test operation, see the sections on “Wiring for the Receiver” and
“Test Operation”.
