(green/yellow)

•  Make earth wire a little longer than others. (More than 45 mm)

•  For future servicing, give extra length to the connecting wires.

•  Do not fold the excess wire, or cram it into small space. Take caution not to 

damage the wires.

•  Be sure to attach each screw to its correspondent terminal when securing 

the cord and/or the wire to the terminal block.

2-5. CONNECTING WIRES FOR INDOOR UNIT

1) Remove VA clamp.

2) Pass indoor/outdoor unit connecting wire (A) from the back of the indoor unit 

and process the end of the wire.

3) Loosen terminal screw, and connect first the earth wire, then indoor/outdoor 

unit connecting wire (A) to the terminal block. Be careful not to make mis-

wiring. Fix the wire to the terminal block securely so that no part of its core is 

appeared, and no external force is conveyed to the connecting section of the 

terminal block. 

4) Firmly  tighten  the  terminal  screws  to  prevent  them  from  loosening.  After 

tightening, pull the wires lightly to confirm that they do not move.

5) Secure indoor/outdoor unit connecting wire (A) and the earth wire with the VA 

clamp. Never fail to hook the left claw of the VA clamp. Attach the VA clamp 

securely.
