Installation
Read completely, then follow step by step.
1. Installation of Indoor, Outdoor unit
1) Select the best location
1. Indoor unit
■ 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 5cm. The unit should be
installed as high on the wall as possible, allowing
a minimum of 5cm from ceiling.
■ Use a stud finder to locate studs to prevent
unnecessary damage to the wall.
2. Outdoor unit
■ 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.
■ 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.
■ Do not place animals and plants in the path of the
warm air.
■ Take the air conditioner weight into account and
select a place where noise and vibration are minimum.
■ Select a place so that the warm air and noise
from the air conditioner do not disturb neighbors.
■ Rooftop Installations:
If the outdoor unit is installed on a roof structure,
be sure to level the unit. Ensure the roof structure
and anchoring method are adequate for the unit
location. Consult local codes regarding rooftop
mounting.

3) How to fix installation plate
The wall you select should be strong and solid enough to prevent
vibration
1. Mount the installation plate on the wall with four
type A screws. If mounting the unit on a concrete
wall, use anchor bolts.
§ Mount the installation plate horizontally by align-
ing 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.

4) Drill a hole in the wall
■ Drill the piping hole with a ø70mm hole core drill.
Drill the piping hole at either the right or the left
with the hole slightly slanted to the outdoor side.

1) Flaring work
Main cause for gas leakage is due to defect in flaring work. Carry out correct flaring work in the following procedure.
1. Cut the pipes and the cable.
■ Use the piping kit accessory or the pipes purchased locally.
■ Measure the distance between the indoor and the
outdoor unit.
■ Cut the pipes a little longer than measured distance.
■ Cut the cable 1.5m longer than the pipe length.
2. Burrs removal
■ Completely remove all burrs from the cut cross
section of pipe/tube.
■ 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.
3. 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)

4. Flaring work
■ Carry out flaring work using flaring tool as shown
below.
Firmly hold copper pipe in a die in the dimension
shown in the table above.
5. Check
■ Compare the flared work with figure below.
■ If flare is noted to be defective, cut off the flared
section and do flaring work again.

2. Flaring Work and Connection of Piping
- 26 -
2) Connection of piping-Indoor
■ Preparing the indoor unit's piping and drain hose
for installation through the wall.
■ Remove the plastic tubing retainer(see illustration below) and pull the tubing and drain hose
away from chassis.
■ Replace the plastic tubing holder in the original
position.
1. Route the indoor tubing and the drain hose in the
direction of rear left.
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 con-
nection later.
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).
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.
5. Connecting the pipings to the indoor unit and
drain hose to drain pipe.
■ Align the center of the pipings and sufficiently
tighten the flare nut by hand.
NOTE:
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.
To remove the holder,
press the bottom of
chassis near the holder
upward and pull the tab
out of its hole.
