Installation
Selection of the best location
CAUTION : In case that the unit is installed near the sea, the installation parts
may be corroded by salt. The installation parts (and the unit) should be taken
appropriate anti-corrosion measures.
•Do not have any heat or steam near the unit.
•Select a place where there are no obstacles in front of the unit.
•Make sure that condensation drainage can be conveniently routed away.
Do not install near a doorway.
•Ensure that the space around the left and right of the unit is more than 50cm. The unit should be installed as high on the
wall as possible, allowing a minimum of 10cm from ceiling.
•Use a stud finder to locate studs to prevent unnecessary damage to the wall.

Preparing Work for Installation
The wall you select should be strong and solid enough
to prevent vibration
1) Open panel front
•First pull down the grille bottom, then remove
screws(2 pieces), and close grille bottom again.
•The moment of lifting the both lower parts of panel
front, you can hear sound this panel came out. In
this time panel front is separated
•After pulling down this panel a bit, separate con-
necting wire with product.
2) Cover pipe and cover side remove
•Remove two screws.(for fixing cover pipe)
•Pull up the cover side of desired connecting direc-
tion, then cover side is separated.
•In case connecting direction is left or right, path
through the hole of cover side.
(When path through the hole, take care of burr.)
When connecting pipe path through rear
wall, don’t remove the hole.
3) Drain hose junction
•Remove the rubber stopple of desired drain direc-
tion.
•As the following picture, insert drain hose in the han-
dle of drain pan, and join drain hose and connecting
hose.

•Preparing the indoor unit's piping and drain hose for
installation through the wall.
1) Route the indoor tubing and the drain hose in the
direction of rear left or right.
2) Tape the tubing, drain hose, and the connecting
cable. Be sure that the drain hose is located at the
lowest side of the bundle. Locating at the upper side
can cause drain pan to overflow inside the unit.
If the drain hose is routed inside the room,
insulate the hose with an insulation material*
so that dripping from "sweating"(condensa-
tion) will not damage furniture or floors.
*Foamed polyethylene or equivalent is recommended.
3) Connecting the pipings to the indoor unit and
drain hose to drain pipe.
•Align the center of the pipes and sufficiently tighten
the flare nut by hand.
•Tighten the flare nut with a wrench.
•When extending the drain hose at the indoor unit,
install the drain pipe.
4) Wrap the insulation material around the connect-
ing portion.
•Overlap the connection pipe insulation material and
the indoor unit pipe insulation material. Bind them
together with vinyl tape so that there is no gap.

1) To check the drainage.
•Pour a glass of water on the evaporator.
•Ensure the water flows through the drain hose of
the indoor unit without any leakage and goes out
the drain exit.
2) Drain piping
•The drain hose should point downward for easy
drain flow.
•Do not make drain piping.

Circuit Breaker
Use a circuit
breaker or time
delay fuse.
•Connect the cable to the indoor unit by connecting the wires to the terminals on the control board in-
dividually according to the outdoor unit connection. (Ensure that the color of the wires of the outdoor unit
and the terminal No. are the same as those of the indoor unit.)
The earth wire should be longer than the common wires.
•When installing, refer to the circuit diagram
on the Control Box of Indoor Unit.
•When installing, refer to the wiring diagram
on the Control Cover Inside Outdoor Unit.

CAUTION
•The above circuit diagram is subject to change without notice.
•Be sure to connect wires according to the wiring diagram.
•Connect the wires firmly, so that not to be pulled out easily.
•Connect the wires according to color codes by referring the wiring diagram.
CAUTION After the confirmation of the above conditions,
prepare the wiring as follows:
1) Never fail to have an individual power circuit specifically for the air conditioner. As for the method of
wiring, be guided by the circuit diagram posted on the inside of control cover.
2) The screws which fasten the wiring in the casing of electrical fittings are liable to come loose from vibra-
tions to which the unit is subjected during the course of transportation. Check them and make sure that
they are all tightly fastened. (If they are loose, it could cause burn-out of the wires.)
3) Specification of power source.
4) Confirm that electrical capacity is sufficient.
5) See to that the starting voltage is maintained at more than 90 percent of the rated voltage marked on the
name plate.
6) Confirm that the cable thickness is as specified in the power source specification.
(Particularly note the relation between cable length and thickness.)
7) Always install an earth leakage circuit breaker where it is wet or moist.
8) The following would be caused by voltage drop.
•Vibration of a magnetic switch, which will damage the contact point, fuse breaking, disturbance of the normal
function of the overload protection device.
9) The means for disconnection from a power
supply shall be incorporated in the fixed wiring and have an air gap contact separation of at least 3mm in
each active(phase) conductors.
CAUTION If a power plug is not to be used,
provide a circuit breaker between power
source and the unit as shown below.
