Safety Precautions

ENGLISH

CAUTION

n Installation

Install the drain hose to ensure that drain

can be securely done.

• Otherwise, it may cause water leakage.

Install the product so that the noise or hot

wind from the outdoor unit may not cause

any damage to the neighbors.

• Otherwise, it may cause dispute with the neigh-

bors.

Always inspect gas leakage after the instal-

lation and repair of product.

• Otherwise, it may cause the failure of product.

Keep level parallel in installing the product.

• Otherwise, it may cause vibration or water leak-

age.

Avoid excessive cooling and perform venti-

lation sometimes.

• Otherwise, it may do harm to your health.

Use a soft cloth to clean. Do not use wax,

thinner, or a strong detergent.

• The appearance of the air conditioner may de-

teriorate, change color, or develop surface

flaws.

Do not use an appliance for special purposes

such as preserving animals vegetables, preci-

sion machine, or art articles.

• Otherwise, it may damage your properties.

Do not place obstacles around the flow inlet

or outlet.

• Otherwise, it may cause the failure of appliance

or an accident.

n Operation

Safety Precautions

Installation of Indoor, Outdoor Unit

Read completely, then follow step by step.

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 the unit is unobstructed, allow proper space on all sides according to the arrows and dis-

tance measurements in the figures.

Use a Metal Detector or Metal Scanner to locate studs to prevent unnecessary damage to the wall.

Outdoor unit

1. If an awning is built over the unit to prevent di-

rect sunlight or rain exposure, make sure that

heat radiation from the condenser is not re-

stricted.

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.

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 struc-

ture and anchoring method are adequate for the

unit location. Consult local codes regarding

rooftop mounting.

Seaside Applications and Installation

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.

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 27 1/16 inches(70cm)

of space between outdoor unit and the windbreak

for easy air flow.

Sea wind Sea wind

Periodic ( more than once/year ) cleaning of the dust or salt particles stuck on the heat exchanger

using water is recommended.

Seasonal Wind And Cautions In Winter

- Sufficient measures are required in a snow area or severe cold area in winter so that product can

be operated well.

- Get ready for seasonal wind or snow in winter even in other areas.

- Install a suction and discharge duct not to let in snow or rain.

- Install the outdoor unit not to come in contact with snow directly. If snow piles up and freezes on the

air suction hole, the system may malfunction. If it is installed at snowy area, attach the hood to the

system.

- Install the outdoor unit at the higher installation console by 50cm than the average snowfall (annual

average snowfall) if it is installed at the area with much snowfall.

- Where snow accumulated on the upper part of the Outdoor Unit by more than 10cm, always re-

move snow for operation.

1. The height of H frame must be more than 2 times the snowfall and its width shall not exceed the

width of the product. (If width of the frame is wider than that of the product, snow may accumulate)

2. Don't install the suction hole and discharge hole of the Outdoor Unit facing the seasonal wind.

• 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 cook-

ing 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.

NOTICE

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.

HEAT INSULATION

1. Use the heat insulation material for the refrigerant piping which has an excellent heat-resis-

tance [over 248°F(120°C)].

2. Precautions in high humidity circum-

stance:

If it is operated for a long time in high

humid atmosphere [dew point tempera-

ture: more than 73.4°F(23°C)], water

drops are liable to fall. In this case, add

heat insulation material according to the

following procedure:

• Heat insulation material to be prepared... Adiabatic glass wool with thickness 10 to 20mm.

• Stick glass wool on all air conditioners that are located in ceiling atmosphere.

CAUTION : The supplied flexi-

ble drain hose should not be

curved, neither screwed. The

curved or screwed hose may

cause a leakage of water.

[Ceiling Concealed Duct/Ceiling Cassette Type]

• Drain piping must have down-slope (1/50 to 1/100): be

sure not to provide up-and-down slope to prevent rever-

sal flow.

• During drain piping connection, be careful not to exert

extra force on the drain port on the indoor unit.

• The outside diameter of the drain connection on the in-

door unit is 1 1/4 inch(32mm).

•

Be sure to install heat insulation on the drain piping.

Piping material: Polyvinyl chloride pipe inner

diometes 1 inch(Ø 25mm) and pipe fittings

• Connect the main drain pipe to the exterior and

leave it provisionally until the test comes to an

end.

• Feed water to the flexible drain hose and check

the piping for leakage.

• Be sure to check the drain pump for normal op-

erating and noise when electrical wiring is com-

plete.

• When the test is complete, connect the flexible

drain hose to the drain port on the indoor unit.

The air conditioner uses a drain pump to drain water.

Use the following procedure to test the drain pump operation:

Heat insulation material: Polyethylene foam

with thickness more than 5/16 inch(8mm).
