8. DRAIN PIPING

• 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 1-1/2" (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. 31 )
• Do not perform air bleeding.
• Always heat insulate (11/32" (8 mm) or over thick) the
indoor side of the drain pipe.

9. ELECTRICAL WIRING

HOW TO CONNECT WIRING TO THE TERMINALS

A. For solid core wiring (or F-cable)
(1) Cut the wire end 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 end with a wire cutter or wire cut-
ting 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, 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.
