10.3.3. Connecting the wires

1

 Remove the one screw securing the connector box cover, and then open the cover.

2

 Securely connect the junction wire connector of the vane motor and the panel vane 

motor wire connector in the connector box. (Fig. 10-8)

  There are two vane motor connectors: one blue connector and one orange con-

nector. Make sure that the connector colors match when connecting them.

3

 Close the connector box cover.

  When closing the connector box cover, slide the cover in the direction indicated by 

the arrow and make sure that the projection is firmly inserted. (Fig. 10-9)

 Caution:

•  Place the band securing the panel vane motor wire in the connector box as 

shown in the diagram. (Fig. 10-10)

•  When closing the connector box cover, make sure that the wires do not get 

pinched.

10.3.4. Wiring the i-See sensor corner panel and signal receiver

•  Install the i-See sensor and signal receiver at the corners of the panel at the loca

-

tions stamped with “○” or “□”. (The positions may be reversed.)

•  Route the i-See sensor and signal receiver wires through the square holes at the 

corners of the panel and install them.

•  Connect the junction wire connector and the wire connectors of the i-See sensor 

and signal receiver in the connector box.

•  Close the connector box cover.

•  Secure the i-See sensor and signal receiver wires to the panel with the fastener 

as shown in the diagram so that there is no slack in the wires, and then cut off the 

excess end of the fastener. (Fig.10-12)

•  Place the i-See sensor and signal receiver wires to the inside of the flange on the 

panel.

•  If the position of the i-See sensor was changed from the “○” position (E) to the “□” 

position (F), change the function settings. (Refer to page 13.)

 Caution:

•  Route the i-See sensor and signal receiver wires as shown in Fig. 10-13.

•  Place the excess portions of the i-See sensor and signal receiver junction 

wires in the electric component box in the wire clip as shown in the diagram, 

and secure the wires together with the fastener. (Fig. 10-14)

  Make sure that the band securing the i-See sensor and signal receiver junction 

wires is positioned inside the connector box. (Fig. 10-15)

•  If the vane motor connectors and signal receiver connector are connected 

incorrectly, the vanes will not move or communication with the remote con

-

troller will not be possible.
