7.2.1 How to Connect Wiring to the Terminals
(1)
For solid core wiring
1)
Cut the wire end with a wire cutter or wire-cutting pliers, then strip the insulation about 25
mm (15/16") .
2) Using a screwdriver, remove the terminal screw(s) on the terminal board.
3)
Using pliers, bend the solid wire to form a loop suitable for the terminal screw.
4)
Shape the loop wire properly, place it on the terminal board and tighten securely with the
terminal screw using a screwdriver.
(2)
For strand wiring
1)
Cut the wire end with a wire cutter or wire-cutting pliers, then strip the insulation about 10
mm (3/8") .
2) Using a screwdriver, remove the terminal screw (s) on the terminal board.
3)
Using a round terminal fastener or pliers, securely clamp a round terminal to each stripped
wire end.
4)
Position the round terminal wire, and replace and tighten the terminal screw with a
screwdriver.

7.2.2 How to Fix Connection Cord and Power Cord at the Cord Clamp
After passing the connection cord and power cord through the insulation tube, fasten it with the
cord clamp.
WARNING!
Before starting work, check that power is not being supplied to the indoor unit and outdoor unit.
Match the terminal block numbers and connection cord colors with those of the indoor unit side.
Erroneous wiring may cause burning of the electric parts.
Connect the connection cords firmly to the terminal block. Imperfect installation may cause a fire.
Always fasten the outside covering of the connection cord with cord clamps. (If the insulator is not
clamped, electric leakage may occur.)
Always connect the ground wire.
Select power cable matched to the fuse capacity.
Use VW-1, 12mm diameter, 0.5 to 1.0mm thick, PVC tube as the insulation tube.
