6.3. Cutting the hole in the wall for the
connecting piping
(1) Cut a 65 mm (2-9/16 in.) 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
(3/16 to 13/32 in.)) than the inside end.
(3) Always align the center of the wall hole. If misaligned, wa-
ter 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 À ow freely.

tioned horizontally and vertically. If the wall hook bracket
is titled, water will drip to the À oor.

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
• Insert drain hose and drain cap securely. Drain should
slope down to avoid water leakage.
• When inserting, be sure not to attach any material
besides water. If any other material is attached, it will
cause deterioration and water leakage.
• After removing drain hose, be sure not to forget
mounting drain cap.
• Be sure to ¿ x the drain hose with tape to the bottom of
piping.
• Prevent drain water freezing under low temperature
environment.
When installing indoor unit's drain hose outdoors,
necessary measure for frost protection should be taken
to prevent drain water freezing.
Under low temperature environment (when outdoor
temperature under 32 °F), after cooling operation is
executed, water in the drain hose could be frozen.
Once drain water is frozen, the drain hose will be
blocked and water leakage may result at the indoor
unit.
