ENGLISH

• 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.

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 place where noxious gas is generat-

ed.

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.

- Be sure to execute heat insulation on the drain piping.

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

Piping material: Polyvinyl chloride pipe VP25 and pipe fittings

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.

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:

- 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.

HEAT INSULATION

- Use the heat insulation material for the refrigerant piping which has an excellent heat-resistance (over 120°C).

- 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

Wiring Connection

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

- Remove the control box cover for electrical connection between the indoor and outdoor unit. (Remove screws ¿)

- Use the cord clamper to fix the cord.
