2. Select a place where there are no obstacles in front
of the unit.
3. Make sure that condensation drainage can be conve-
niently routed away.
4. Do not install near a doorway.
5. Ensure that the interval between a wall and the left
(or right) of the unit is more than 50cm. The unit
should be installed as high as possible on the wall,
allowing a minimum of 10cm from ceiling.
6. Use a stud finder to locate studs to prevent unneces-
sary damage to the wall.

1. If an awning is built over the unit to prevent direct
sunlight or rain exposure, make sure that heat radia-
tion from the condenser is not restricted.
2. Ensure that the space around the back and sides is
more than 10cm. The front of the unit should have
more than 70cm of space.
3. Do not place animals and plants in the path of the
warm air.
4. Take the weight of the air conditioner into account
and select a place where noise and vibration are min-
imum.
5. Select a place where the warm air and noise from the
air conditioner do not disturb neighbors.

Installation
The wall you select should be strong and solid
enough to prevent vibration
1. Mount the installation plate on the wall with
type "A" screws. If mounting the unit on a con-
crete wall, use anchor bolts.
•Mount the installation plate horizontally by aligning
the centerline using a level.
2. Measure the wall and mark the centerline. It is
also important to use caution concerning the
location of the installation plate-routing of the
wiring to power outlets is through the walls typi-
cally. Drilling the hole through the wall for piping
connections must be done safely.

Flaring Work
Main cause for gas leakage is due to defect in flaring work. Carry out correct flaring work in the following procedure.
Cut the pipes and the cable.
1. Use the piping kit accessory or the pipes purchased
locally.
2. Measure the distance between the indoor and the
outdoor unit.
3. Cut the pipes a little longer than measured distance.
4. Cut the cable 1.5m longer than the pipe length.
Burrs removal
1. Completely remove all burrs from the cut cross sec-
tion of pipe/tube.
2. Put the end of the copper tube/pipe in a downward
direction as you remove burrs in order to avoid drop-
ping burrs into the tubing.
Putting nut on
•Remove flare nuts attached to indoor and outdoor unit,
then put them on pipe/tube having completed burr
removal.
(not possible to put them on after flaring work)
Flaring work
1. Firmly hold copper pipe in a die in the dimension
shown in the table below.
2. Carry out flaring work with the flaring tool.

Check
1. Compare the flared work with the figure by.
2. If a flared section is defective, cut it off and do flar-
ing work again.
Indoor
1. Prepare the indoor unit's piping and drain hose for installation through the wall.
2. Remove the plastic tubing retainer(see the illustra-
tion by) and pull the tubing and drain hose away
from chassis.
3. Replace only the plastic tubing holder 1, not the
holder 2 in the original position.
1. Route the indoor tubing and the drain hose in the
direction of rear right.
2.
Insert the connecting cable into the indoor unit from
the outdoor unit through the piping hole.
•Do not connect the cable to the indoor unit.
•Make a small loop with the cable for easy connec-
tion later.
3. 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 uper side
can cause drain pan to overflow inside the unit.
CAUTION: If the drain hose is routed inside
the room, insulate the hose with an insula-
tion material* so that dripping from "sweat-
ing"(condensation) will not damage furniture
or floors.
*Foamed polyethylene or equivalent is rec-
ommended.

4. Indoor unit installation
Hook the indoor unit onto the upper portion of the
installation plate.(Engage the two hooks of the rear
top of the indoor unit with the upper edge of the
installation plate.) Ensure that the hooks are prop-
erly seated on the installation plate by moving it left
and right.
Press the lower left and right sides of the unit
against the installation plate until the hooks engage
into their slots(clicking sound).
Connecting the piping to the indoor unit and drain
hose to drain pipe.
1. Align the center of the pipes and sufficiently tighten
the flare nut by hand.
2. Tighten the flare nut with a wrench.
3. When extending the drain hose at the indoor unit,
install the drain pipe.
Wrap the insulation material around the connect-
ing portion.
1. Overlap the connection pipe insulation material and
the indoor unit pipe insulation material. Bind them
together with vinyl tape so that there may be no
gap.
2. Wrap the area which accommodates the rear piping
housing section with vinyl tape.
3. Bundle the piping and drain hose together by wrap-
ping them with vinyl tape for enough to cover where
they fit into the rear piping housing section.
