•  Perform securely the electrical wiring work. If the electrical work is not completed, heat generation at the connection, a fire or an electric shock 

may occur.

•  Make  sure  that  the  wires  are  securely  fixed  in  order  not  to  apply  an  external  force  to  the  terminal  connections  of  the  wirings.  If  fixing  is  not 

completed, heat generation or a fire will occur.

The following connectors are used in the air panel. Remove the tape fixing the wiring connectors on the air panel and pull out them. 
Connect them with the wiring connectors to CN7 and CN10 in the electrical box as the following figure.

N O T E

Before the electrical wiring work, turn OFF the power source. If the connectors are connected without turning OFF the power source, the auto swing 

louvre can not activate.

After completing the wiring connection of the air panel, attach 
the air inlet grille. Perform the attaching work in the reverse 
procedure of removing. Refer to item 3 of the section 

"12.4 

Installation".

 Hook the swivel of the supporting string at 

 to 

the hole at the air panel. The air inlet grille can be attached from 
any 4 directions by rotating it. When multiple indoor units are 
installed or requested from a user, the air intake grille direction 
can be selected freely.

This motion sensor can be installed to any four corners of the air 
panel. In the case of installing it to far corner from the electrical 

box, run through the wiring for the motion sensor kit on the fixing 

plate of the unit between the motion sensor kit and the electrical 
box of the unit.
After running the connecting cable, clamp the extra length of the 
connecting cable by the plastic band and store it at inside the 
ceiling.
