2. BENDING PIPES

The pipes are shaped by your hands. Be careful not to
collapse them.

3. CONNECTION PIPES

Centering the pipe against port on the indoor unit,
turn the flare nut with your hand (Fig. 24).

Be sure that the small pipe is completely installed
before connecting the large pipe.

Do not bend the pipes in an angle more than 90°.
When pipes are repeatedly bent or stretched, the

material will harden, making it difficult to bend or
stretch them any more. Do not bend or stretch the
pipes more than three times.

When bending the pipe, do not bend it as is. The pipe
will be collapsed. In this case, cut the heat insulating
pipe with a sharp cutter as shown in Fig. 23, and bend
it after exposing the pipe. After bending the pipe as
you want, be sure to put the heat insulating pipe back
on the pipe, and secure it with tape.

Be sure to apply the pipe against the
port on the indoor unit correctly. If the
centering is improper, the flare nut
cannot be tightened smoothly. If the flare
nut is forced to turn, the threads will be
damaged.

6. ELECTRICAL WIRING

B.If round terminal cannot be used, the

following items should be followed.
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
1/2” (12.7 mm) to expose the solid wire.

(2) Using a screwdriver, remove the terminal

screw(s) on the terminal board.

(3) Wires with the same diameter should be

connected on both sides as shown in Fig. 33.
Since connecting wires with different diameters

causes the wires to heat up due to loose
connections, this method should not be used.

HOW TO FIX THE CONNECTION CORD

After passing the connection cord through the
insulation tube, fasten it with the cord clamp.

Use VW-1, 0.5 to 1.0 mm thick, PVC tube as the
insulation tube.

Fig. 34

Insulation tube

Insulation tube

Cord clamp

(1) Before starting work, check that

power is not being supplied to the
indoor unit.

(2) Match the terminal board numbers

and connection cord colors with
those of the indoor unit.
Erroneous wiring may cause burning
of the electric parts.

(3) Connect the connection cord firmly

to the terminal board. Imperfect
installation may cause a fire.

(4) Always fasten the outside covering

of the connection cord with the cord
clamp. (If the insulation is chafed,
electric leakage may occur.)

(5) Always connect the ground wire.

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,

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 screw­driver.
