7. HOW TO CONNECT WIRING TO THE TERMINALS
A. For solid core wiring (or F-cable)
(1) Cut the wire and with a wire cutter or wire-cut-
ting pliers, then strip the insulation to about
15/16" (25 mm) to expose the 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 ter-
minal board and tighten securely with the termi-
nal screw using a screwdriver.
B. For strand wiring
(1) Cut the wire and with a wire cutter or wire-cut-
ting pliers, then strip the insulation to about 3/8"
(10 mm) of expose the strand wiring.
(2) Using a screwdriver, remove the terminal
screw(s) on the terminal board.
(3) Using a round terminal fastener or pliers, secure-
ly 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.

Always use H07RNF or equivalent as the connection
cord
9. 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.
1. INDOOR UNIT SIDE
(1) Remove the electric component box.
