1. IF ONE WIRE IS CONNECTED TO ONE
TERMINAL BLOCK
A. For solid core wiring (or F-cable)
(1) Cut the wire end with a wire cutter or wire-
cutting 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.
2. IF TWO WIRES ARE CONNECTED TO
ONE TERMINAL BLOCK.
A. As a rule, round terminal should be used
to connect to the terminal block.
(1) Cut the wire end with a wire cutter or wire-
cutting pliers, then strip the insulation to about
3/8” (10 mm) to 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.
B. For strand wiring
(1) Cut the wire end with a wire cutter or wire-
cutting pliers, then strip the insulation to about
3/8” (10 mm) to 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-dri-
ver.

• Install the drain pipe with downward gradient (1/50 to
1/100) and so there are no rises or traps in the pipe.
• Use general hard polyvinyl chloride pipe (VP25)
[outside diameter 38 mm].
• During installation of the drain pipe, be careful to
avoid applying pressure to the drain port of the
indoor unit.
• When the pipe is long, install supporters (Fig. 27).
• Do not perform air bleeding.
• Always heat insulate (8 mm or over thick) the indoor
side of the drain pipe.
(1) Install insulation for the drain pipe ( See Figs. 28 and
29).
Cut the included insulation material to an appropri-
ate size and adhere it to the pipe.
(2) If "
q
Right rear piping": fasten the drain pipe with
VT wire so that the pipe slopes correctly within the
indoor unit (Fig. 30).
