6.3. Cutting the hole in the wall for the connecting piping
(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 left piping and right piping, cut the hole a little lower so that drain water will flow
freely.

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
[Rear piping, Right piping, Bottom 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.
[For Left rear piping, Left piping]
Interchange the drain cap and the drain hose.
CAUTION
• I nsert drain hose and drain cap securely. Drain should slope down to avoid water leakage.
• W hen 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.
• A fter you remove a drain hose, be sure to attach the drain cap.
• W hen you secure the piping and drain hose with tape, arrange the drain hose so that
it is at the bottom of the piping.
• F or 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 flow in the hose, and may cause water leakage at the indoor unit.
Installing the Drain cap
Use a hexagonal wrench 4 mm at opposite side to
insert the drain cap, till the drain cap contacts the tip
of the drain cock.
