anything on the product.
(outdoor unit)
•There is risk of personal injury
and failure of product.
■Disuse
Always insert the filter securely.
Clean the filter every two weeks
or more often if necessary.
•A dirty filter reduces the efficiency of

12 Room Air Conditioner
Installation
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 2.4meters(8ft).
A minimum pipe run of 7.5meters(24.6ft) is required to minimize vibration and excessive noise.

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.

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 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
•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
connection 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.
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.
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.
