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 10cm(3.9in). 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 air conditioner weight into account and
select a place where noise and vibration are
minimum.
5. 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.
If the outdoor unit is installed on roof structures or walls, this may result in excessive noise and vibration, and may be also classed as non serviceable 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 space around the left and right
of the unit is more than 30cm(11.8in). The unit
should be installed as high on the wall as possible, allowing a minimum of 12cm(4.7in) from
ceiling.
6. Use a stud finder to locate studs to prevent
unnecessary damage to the wall.
Select The Best Location
Install the indoor unit on the wall where the height from the floors more than 2.3meters(7.6ft).
A minimum pipe run of 7.5meters(24.6ft) is required to minimize vibration and excessive noise.

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.

Flaring Work
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(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 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
• Carry out flaring work using flaring tool as shown below.
Main cause for gas leakage is due to defect in flaring work. Carry out correct flaring work in the following procedure.

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.
Route the indoor tubing and the drain
hose in the direction of rear left.
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.
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 recom-
mended.
Indoor unit installation
• Hook the indoor unit onto the upper portion of
the installation plate.(Engage the three hooks of
the rear top and rear lower of the indoor unit with
the upper edge and lower edge of the installation
plate.) Ensure that the hooks are properly seated
on the installation plate by moving it left and
right.
