6. INSTALLATION WORK
During transportation and relocation shall be covered by wall hook bracket to the con-
necting pipe. With a connection pipe, that I do not carry.
(When operating, There is a possibility that the stress is applied to the pipe joint, fl am-
mable gas may leak.)
• Do not hit or push the human sensor. This may lead to damage or malfunction.
• Do not touch the human sensor. Any scratches or dirt may lead to incorrect detection.
• Do not place large objects near the human sensor. Also keep heating units outside the
sensor's detection area.
Detection range of the human sensor is as follows.

The piping can be connected in the 6 directions indicated in the following.
When the piping is connected to direction (2) , (3) , (4) or (5) , cut along the piping groove
on the side of the front cover with a hacksaw.

(1) Rear outlet
(3) Bottom outlet
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 fl ow
freely.

Wall
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
• 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.
Tapping screw
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 (Drain hose), Left piping (Drain hose)]
Interchange the drain cap and the drain hose.
• 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 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 fl ow 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.
