6.3. Cutting the hole in the wall for connecting the pipes
(1) Cut a 65 mm diameter hole in the wall at the position shown in the following.
(2) Cut the hole so that the outside end is lower (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 the right piping, cut the hole a little lower so that drain water will ow freely.

WARNING
Always use the wall pipe. If the wall pipe is not used, the cable that is connected between
the indoor unit and the outdoor unit may touch metal, and cause an electric discharge.
6.4. Installing the wall hook bracket
(1) Install the wall hook bracket so that it is correctly positioned horizontally and vertically.
If the wall hook bracket is titled, water will drip to the oor.
(2)
Install the wall hook bracket so that it is strong enough to support the weight of the unit.
• Fasten the wall hook bracket to the wall with 5 or more screws through the holes near
the outer edge of the bracket.
• Check that there is no rattle at the wall hook bracket.

CAUTION
Install the wall-hook bracket both horizontally and vertically aligned.
Misaligned installation may cause water leakage.
6.5. Forming the drain hose and pipe
CAUTION
• Insert drain hose and drain cap securely. Drain should slope down to avoid water leakage.
• When inserting the drain hose, no other material than water should be applied.
Application 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
protection to prevent a frozen drain hose.
After cooling operation is performed in low temperature environment (when outdoor
temperature under 0 °C), water in the drain hose could be frozen. Frozen drain water
will block the water ow in the hose, and may cause water leakage at the indoor unit.
[Rear piping, Right piping]
• Install the indoor unit piping in the direction of the wall hole and bind the drain hose
and pipe together with vinyl tape.
• Install the piping so that the drain hose is at the bottom.
• Wrap the pipes of the indoor unit that are visible from the outside with decorative tape.

CAUTION
Insert the drain hose and drain cap into the drain port, making sure that it comes
in contact with the back of the drain port, and then mount it. If the drain hose is not
connected properly, leaking will occur.
[Installing the indoor unit]
• Hang the indoor unit from the hooks at the top of the wall hook bracket.
• Insert the spacer, etc. between the indoor unit and the wall hook bracket and separate
the bottom of the indoor unit from the wall.
