HOW TO CONNECT WIRING TO THE TERMINALS
A. For solid core wiring (or F-cable)(Fig.19A)
(1) Cut the wire with a wire cutter or wire-cutting pliers, then strip the insulation to about 25mm of the exposed solid wire.
(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 screw driver.
B. For strand wiring(Fig.19B)
(1) Cut the wire with a wire cutter or wire-cutting pliers, then strip the insulation to about 10mm of the exposed strand wiring.
(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 using a screw driver.

HOW TO FIXED CONNECTION CORD AND POWER CABLE AT THE CORD CLAMP
After passing the connection cord and power cable through the insulation tube, fasten it with the cord clamp, as shown in Fig.20
ELECTRICAL WIRING
(1) Match the terminal block numbers and connection cord colors with those of the
outdoor unit.
Erroneous wiring may cause burning of the electric parts.
(2) Connect the connection cords firmly to the terminal block. Imperfect installation
may cause a fire.
(3) Always fasten the outside covering of the connection cord with the cord clamp.
(If the insulator is chafed, electric leakage may occur.)
(4) Always connect the ground wire.
