TIPS FOR SAVING ENERGY

Here are some tips that will help you minimize the power consumption when you use the air
conditioner. You can use your air conditioner more efficiently by referring to the instructions
below:

• Do not cool excessively indoors. This may be harmful for your health and may consume more
electricity.

• Block sunlight with blinds or curtains while you are operating the air conditioner.

• Keep doors or windows closed tightly while you are operating the air conditioner.

• Adjust the direction of the air flow vertically or horizontally to circulate indoor air.

• Speed up the fan to cool or warm indoor air quickly, in a short period of time.

• Open windows regularly for ventilation as the indoor air quality may deteriorate if the air condition­er is used for many hours.

• Clean the air filter once every 2 weeks. Dust and impurities collected in the air filter may block the
air flow or weaken the cooling / dehumidifying functions.

Installation

• Always check for gas (refrigerant) leakage after installation or repair of product. Low refrigerant lev-

els 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 damage the neigh-

borhoods. 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 cor-

rosion on the product. Corrosion, particularly on the condenser and evaporator fins, could cause
product malfunction or inefficient operation.

Operation

• Do not expose the skin directly to cool air for long periods of time. (Don't sit in the draft.) This could

harm to your health.

• Do not use the product for special purposes such as preserving foods, works of art, etc. It is a con-

sumer air conditioner, not a precision refrigeration system. There is risk of damage or loss of proper­ty.

• Do not block the inlet or outlet of air flow. It may cause product failure.

• Use a soft cloth to clean. Do not use harsh detergents, solvents, etc. There is risk of fire, electric

shock, or damage to the plastic parts of the product.

• Do not touch the metal parts of the product when removing the air filter. They are very sharp! There

is risk of personal injury.

• Do not step on or put anyting on the product. (outdoor units) There is risk of personal injury and fail-

ure of product.

• Always insert the filter securely. Clean the filter every two weeks or more often if necessary. A dirty

filter reduces the efficiency of the air conditioner and could cause product malfunction or damage.

• Do not insert hands or other objects through the air inlet or outlet while the product is operated.

There are sharp and moving parts that could cause personal injury.

• Do not drink the water drained from the product. It is not sanitary and could cause serious health

issues.

• Use a firm stool or ladder when cleaning or maintaining the product. Be careful and avoid personal

injury.

• Replace the all batteries in the remote control with new ones of the same type. Do not mix old and

new batteries or different types of batteries. There is risk of fire or explosion

• Do not recharge or disassemble the batteries. Do not dispose of batteries in a fire. They may burn or

explode.

• If the liquid from the batteries gets onto your skin or clothes, wash it well with clean water. Do not

use the remote if the batteries have leaked. The chemicals in batteries could cause burns or other
health hazards.

• If you eat the liquid from the batteries, brush your teeth and see doctor. Do not use the remote if
the batteries have leaked. The chemicals in batteries could cause burns or other health hazards.

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.

NOTE

!

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 places where noxious gas is gener-

ated.

5 Avoid places near high frequency genera-

tors.

Indoor Unit Drain Piping

- Drain piping must have down-slope (1/50 to
1/100): be sure not to provide up-and-down
slope to prevent reversal 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 indoor unit is 32mm.

Piping material: Polyvinyl chloride pipe VP­25 and pipe fittings

- Install the drain raising pipes at a right
angle to the indoor unit and no more than
300mm from the unit.

Drain test

The air conditioner uses a drain pump to drain
water.
Use the following procedure to test the drain
pump operation:

- 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
operating and noise when electrical wiring is
complete.

- When the test is complete, connect the flexi­ble drain hose to the drain port on the indoor
unit.

- Heat insulation material to be prepared...
Adiabatic EPDM or NBR with thickness
10 to 20mm.

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

- In addition to the normal heat insulation
(thickness: more than 8 mm) for refrigerant
piping (gas piping: thick piping) and drain
piping, add further 10 mm to 30 mm
thickness material.

- Precautions in high humidity circumstance:
This air conditioner has been tested accord­ing to the "KS Standard Conditions with Mist"
and confirmed that there is not any default.
However, if it is operated for a long time in
high humid atmosphere (dew point tempera­ture: more than 23 °C), water drops are liable
to fall. In this case, add heat insulation mate­rial according to the following procedure:

Wiring Connection

-

Open the control box cover and connect the
Remote controller cord and Indoor power wires.

- Remove the control box cover for electrical con-

nection between the indoor and outdoor unit.

- Use the cord clamper to fix the cord.

THE INDOOR UNIT INSTALLATION

Precautions when laying power
wiring

Use round pressure terminals for connections
to the power terminal block.

When none are available, follow the instruc­tions below.

- Do not connect wiring of different thickness­es to the power terminal block. (Slack in the
power wiring may cause abnormal heat.)

- When connecting wiring which is the same
thickness, do as shown in the figure below.

CAUTION

The connecting cable connected to the
indoor and outdoor unit should be com­plied with the following specifications
(This equipment shall be provided with a
cord set complying with the national regu­lation).

!

CAUTION

The Power cord connected to the unit
should be selected according to the fol­lowing specifications.

!

If the supply cord is damaged, it must be
replaced by a special cord or assembly
available from the manufacturer of its
service agent.

It is forbidden to

- For wiring, use the designated power wire
and connect firmly, then secure to prevent
outside pressure being exerted on the termi­nal block.

- Use an appropriate screwdriver for tightening
the terinal screws. A screwdriver with a
small head will strip the head and make prop­er tighterning impossible.

- Over-tightening the terminal screws may
break them.
