Installation
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 "A". The unit should be installed as high on the
wall as possible, allowing a minimum of "B" from ceiling.
• Use a stud finder to locate studs to prevent unnecessary
damage to the wall.
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.

Installation
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 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.
• 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.
• Open the Front Grille.
• Pass Telephone Control Cord Wire through the hole
which the power cord goes through.
• Connect Telephone Control Cord Wire to the phone jack
of telephone PCB of Control Box.
• Fix Telephone Control Cord Wire inside Control box so
as not to disconnect.
• Close the Front Grille.
How to Fix Installation Plate Drill a Hole in the Wall
Drain hose junction
• Remove the rubber stopple in the desired drain direction.
• Insert drain hose into the handle of drain pan, and join
drain hose and connecting hose according to the figure

Flaring work and connection of piping

Flaring work
Flaring work
Main cause for refrigerant leakage is due to defect in the
flaring work. Carry out correct flaring work using the following procedure.
Cut the pipes and the cable.
• Use the piping kit accessory or pipes purchased locally.
• Measure the distance between the indoor and the outdoor unit.
• Cut the pipes a little longer than the measured distance.
• Cut the cable 1.5m longer than the pipe length.
Check
• Compare the flared work with figure below.
• If flare is noted to be defective, cut off the flared sec-
tion and re-flare it.
• 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.(Optional)
• Carry out flaring work using flaring tool as shown below.
Burr 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.
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
• Firmly hold copper pipe in a die in the dimension shown in
the table above.

When install, make sure that the
remaining parts must be removed
clearly so as not to damage the piping and drain hose, especially power
cord and connecting cable.

Drain hose
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 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 pipings to the indoor unit and
drain hose to drain pipe.
• Align the center of the pipes and sufficiently tighten
the flare nut by hand.
• Tighten the flare nut with a wrench.
• When extending the drain hose at the indoor unit, install the
drain pipe.
Wrap the insulation material around the connecting portion.
•Overlap the connection pipe insulation material and the
indoor unit pipe insulation material. Bind them together with
vinyl tape so that there is no gap.
• Wrap the area which accommodates the rear piping housing section with vinyl tape.
