Safety Precautions
WARNING
■ Installation
Always perform grounding.
• Otherwise, it may cause electrical shock.
Ensure that the power cord
used is not frayed or damaged
in anyway.
• Otherwise, it may cause a fire or
electrical shock.
Please contact a licensed service
center or installer to install this
equipment.
•
Otherwise, it may cause a fire, electrical shock, explosion or injury.
Securely attach the electrical
part cover to the indoor unit
and the service panel to the
outdoor unit.
•
If the electrical part cover of the indoor
unit and the service panel of the outdoor unit are not attached securely, it
could result in a fire or electric shock
due to dust, water, etc.
Ensure a dedicated circuit
breaker is installed as well as
an independent electrical dis-
connect.
• No installation may cause a fire
and electrical shock.
Do not keep or use flammable
gases or combustibles near the
air conditioner.
• Otherwise, it may cause a fire or
the failure of product.
Use a vacuum pump or Inert (nitrogen) gas when doing leakage test or air purge. Do not use oxy-
gen, compressed air or other gases which may be flammable or harmful. Doing so causes risk for
fire, explosion, injury or death.
• There is the risk of death, injury, fire or explosion.
Ensure that the outdoor system is free of dam-
age prior to installation.
• It may cause injury or an accident.
Do not service this equipment unless you are a
licensed contractor.
• It will cause a fire or electrical shock.

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 the unit is unobstructed, allow proper
space on all sides according to the arrows
and distance measurements in the figures.
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 sound
from the air conditioner does 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.

Seaside Applications and Installation
1.
Air conditioners should not be installed in areas where corrosive gases, such as acid or alkaline gas, are
produced.
2. Do not install the product where it could be exposed to sea wind (salty wind) directly. It can result
corrosion on the product. Corrosion, particularly on the condenser and evaporator fins, could
cause product malfunction or inefficient performance.
3. If outdoor unit is installed close to the seaside, it should avoid direct exposure to the sea wind.
1) If the outdoor unit is to be installed close to the seaside, direct exposure to the sea wind should be avoided.
Install the outdoor unit on the opposite side of the sea wind direction.
2)
In case, to install the outdoor unit on the seaside, set up a windbreaker/barrier, to lessen the unit's exposure to sea air
3) Select a well-drained place.
• It should be strong enough (like concrete) to obstruct
the wind from the sea.
• The height and width should be more than 150% of
the outdoor unit.
• A minimum of 70cm (27 1/16 inches)
of space between outdoor unit and the windbreak
for easy air flow.
Sea wind Sea wind

Windbreaker/Barrier
Periodic ( more than once/year ) cleaning of the dust or salt particles stuck on the heat exchanger
using water is recommended.

Installation
ENGLISH
Wrap the insulation material around the
connecting portion.
1. Overlap the connection pipe insulation and the
indoor unit pipe heat insulation material. Bind
them together with vinyl tape so that there is no
gap.
2. Wrap the area which accommodates the rear
piping housing section with vinyl tape.
3. Bundle the piping and drain hose together by
wrapping them with vinyl tape over the range
within which they fit into the rear piping housing
section.
Reroute the pipings and the drain hose across
the back of the chassis.
Finishing the indoor unit installation
1.
Mount the tubing holder in the original positon.
2.
Ensure that the hooks are properly seated on the
installation plate by moving it left and right.
3. Press the lower left and right sides of the unit
against the installation plate until the hooks engage into their slots (clicking sound).
4.
Finish the assembly by screwing the unit to the
installation plate by using two pieces of type "C"
screws. And assemble a chassis cover.
If the split type Indoor unit is installed in a wall having 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
/ opening. 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.

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.

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 LCD. display. For proper display of the remote controller
LCD's, the remote controller should be installed properly as shown in Fig.1.
(The standard height is 4~5 ft (1.2~1.5 m) from floor level.)

Ceiling dimension and hanging bolt location
• The dimensions of the paper model for installation are the same as those of the ceiling opening dimensions.
• Avoid the following installation location.
1. Such places as restaurants and kitchen where considerable amount of oil steam and flour is generated.
These may cause heat exchange efficiency reduction, or water drops, drain pump mal-function.
In these cases, take the following actions;
• Make sure that ventilation fan is enough to cover all noxious gases from this place.
• Ensure enough distance from the cooking room to install the air conditioner in such a place where it may not suck oily
steam.
2. Avoid installng air conditioner in such places where
cooking oil or iron powder is generated.
3. Avoid places where inflammable gas is generated.
4. Avoid place where noxious gas is
generated.
5. Avoid places near high frequency
generators.
CAUTION :
• This air-conditioner uses a drain pump.
• Install the unit horizontally using a level gauge.
• During the installation, care should be taken not to damage electric wires.
• Select and mark the position for fixing bolts and piping
hole.
• Decide the position for fixing bolts slightly tilted to the
drain direction after considering the direction of drain
hose.
• Drill the hole for anchor bolt on the wall.
