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 fl ow
freely.

WARNING
If the wall pipe is not used, the cable interconnecting the indoor unit(s) and outdoor unit
may touch metal and cause electric discharge.
6.4. Installing the wall hook bracket
• Remove the wall hook bracket from the indoor unit. (Remove 2 screws).
(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 fl 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.

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 fi 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 0 °C), 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.
Installation method of Drain cap
Use a hexagonal wrench 4 mm at opposite side to insert
the drain cap, till the drain cap contacts the tip of drain
cock.
