3.3.3 Cutting the hole in the wall for the connecting piping

(1) Cut a hole in the wall at the position shown in the following.

(2) Cut the hole so that the outside end is lower (3/16 to 3/8 in (5 to 10 mm)) than the

inside end.

(3) Always align the center of the wall hole. If misaligned, water leakage will occur.

(4) Cut the wall pipe to match the wall thickness, stick it into the wall cap, fasten the cap

with vinyl tape, and stick the pipe through the hole.

(5) For left piping and right piping, cut the hole a little lower so that drain water will flow

freely.

3.3.5 Forming the drain hose and pipe

Insert drain hose and drain cap securely. Drain should slope down to avoid water leak-

age.

When inserting the drain hose, no other material than water should be applied. Applica-

tion of other material than water will cause deterioration of the hose, and may cause

water leakage.

After you remove a drain hose, be sure to attach the drain cap.

When you secure the piping and drain hose with tape, arrange the drain hose so that it

is at the bottom of the piping.

For drain hose piping in low temperature environment, you need to apply freeze protec-

tion to prevent a frozen drain hose.

After cooling operation is performed in low temperature environment, (when outdoor

temperature under 32°F (0°C),) water in the drain hose could be frozen. Frozen drain

water will block the water flow in the hose, and may cause water leakage at the indoor

unit.

[For (A) Rear piping, (B) Right piping and (C) Bottom piping]

(1) Install the indoor unit piping in

the direction of the wall hole

and bind the drain hose and

pipe together with vinyl tape.

(2) Install the piping so that the

drain hose is at the bottom.

(3) Wrap the pipe of the indoor unit

that visible from the outside

with decorative tape.

(4) For right or bottom outlet

piping, cut off the piping outlet

cutting groove with a hacksaw.

[For (D) Left bottom piping, (E) Left piping and (F) Center piping, (G) Left rear

piping]

Insert the drain hose and drain cap into the drain port, making sure that it comes in con-

tact with the back of the drain port, and then mount it. If the drain hose is not connected

properly, leaking will occur.

(1) Interchange the drain cap and the drain hose.

• For left outlet piping, cut off

the piping outlet cutting groove

with a hacksaw.

• Remove the drain cap by pull-

ing at the projection at the end

of the cap with pliers, etc.
