WIRED REMOTE CONTROLLER INSTALLATION
• Since the room temperature sensor is in the remote controller, the remote controller box should be installed in a place away
from direct sunlight, high humidity and direct supply of cold air to maintain proper space temperature.
Install the remote controller about 5ft(1.5m) above the floor in an area with good air circulation at an average temperature.
Do not install the remote controller where it can be affected by:
- Drafts, or dead spots behind doors and in corners.
- Hot or cold air from ducts.
- Radiant heat from sun or appliances.
- Concealed pipes and chimneys.
- Uncontrolled areas such as an outside wall behind the remote controller.
- This remote controller is equipped with a seven segment LED. display. For proper display of the remote controller
LED's, the remote controller should be installed properly as shown in Fig.1.
(The standard height is 1.2~1.5 m from floor level.)

Safety Precautions
6Indoor Unit
■Installation
Always check for gas (refrig-
erant) leakage after installa-
tion or repair of product.
• Low refrigerant levels may
cause failure of product.
Install the drain hose to
ensure that water is drained
away properly.
• A bad connection may cause
water leakage.
Keep level even when
installing the product.
• To avoid vibration or water
leakage.
Do not install the product
where the noise or hot air from
the outdoor unit could dam-
age the neighborhoods.
• It may cause a problem for
your neighbors.
Use two or more people to lift
and transport the product.
• Avoid personal injury.
Do not install the product
where it will be exposed to
sea wind (salt spray) directly.
• It may cause corrosion on the
product. Corrosion, particularly
on the condenser and evapora-
tor fins, could cause product
malfunction or inefficient opera-
tion.
If you eat the liquid from the

Installation Manual 7
Read completely, then follow step by step.
Installation
Selection of the best location
• There should not be any heat source or steam
near the unit.
• There should not be any obstacles to prevent the
air circulation.
• A place where air circulation in the room will be
good.
• A place where drainage can be easily obtained.
• A place where noise prevention is taken into con-
sideration.
• Do not install the unit near the door way.
• Ensure the spaces indicated by arrows from the
wall, ceiling, fence, or other obstacles.
The mounting wall should be strong and solid
enough to protect it from the vibration.

Fixing Installation Plate
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 con-
crete 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 loca-
tion 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.

Piping Method
CAUTION : 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.
■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 connection
later.
■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.
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 drip-
ping from "sweating"(condensation) will not damage furni-
ture 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).
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.
NOTICE
For left rear piping
To remove the holder,
press the bottom of
chassis near the holder
upward and pull the tab
out of its hole.

■Tighten the flare nut with a wrench.
■When extending the drain hose at the indoor unit,
install the drain pipe.
6. Wrap the insulation material around the connect-
ing 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 pip-
ing housing section with vinyl tape.
■Bundle the piping and drain hose together by
wrapping them with vinyl tape over the range with-
in which they fit into the rear piping housing sec-
tion.
1. Route the indoor tubing and the drain hose to the
required piping hole position.
2. Insert the piping, drain hose and the connecting
cable into the piping hole.

If the split type Indoor unit is installed in a wall hav-
ing hole or opening near by or back side of the unit,
then the air from other side of the wall can come
inside the condition space through that hole/ open-
ing. That air can cause unwanted dew/ water
droplet formation when it comes in contact with
body of the indoor unit. So all hole or opening on
the wall must be blocked very well to avoid water
dropping from the body of the unit.
