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.
• 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.
When installing the unit, securely connect the refrigerant pipes before
starting the compressor.
