Installation
Indoor unit
1. Do not have any heat or steam near the unit.
2. Select a place where there are no obstacles
in front of the unit.
3. Make sure that condensation drainage can be
conveniently 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
10cm(3.9in). The unit should be installed as
high as possible on the wall, allowing a
minimum of 20cm(7.9in) from ceiling.
6. Use a stud finder to locate studs to prevent
unnecessary damage to the wall.
Outdoor unit
1. If an awning is built over the unit to prevent
direct sunlight or rain exposure, make sure
that heat radiation from the condenser is not
restricted.
2. Ensure that the space around the back and
sides is more than 30cm(11.8in). The front of
the unit should have more than 70cm(27.6in)
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 minimum.
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
concrete 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 typically. Drilling the hole through the
wall for piping connections must be done
safely.
3. Install after removing one of the indicated
cutting phase according to the installation
location of the indoor unit's piping.
Fixing Installation Plate
•Drill the piping hole with a ø70mm(2.76in)
hole core drill. Drill the piping hole at either
the right or the left with the hole slightly
slanted to the outdoor side.

Flaring Work
Main cause for gas leakage is due to defect in flaring work. Carry out correct flaring work in the
following procedure.
Cutting Tubes
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(59.1in) longer than the pipe
length.
Burrs removal
1. Completely remove all burrs from the cut cross
section of pipe/tube.
2. Put the end of the copper tube/pipe in a
downward direction as you remove burrs in
order to avoid dropping 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 Bar 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 flaring 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
illustration 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
connection 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 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"(condensation)
will not damage furniture or floors.
*Foamed polyethylene or equivalent is
recommended.

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 properly 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
connecting 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
wrapping them with vinyl tape for enough to
cover where they fit into the rear piping
housing section.
