• 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

generated.

5 Avoid places near high frequency

generators.

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 32 mm.

- 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 300 mm from the unit.

Heat insulation material: Polyethylene foam with thickness more than 8 mm.

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

- 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 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 20 mm.

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

Wiring Connection

- Open the control box cover and connect the Remote controller cable 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.

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 cable set complying with the national regulation). (Rubber insulation, type H05RN-F approved by HAR or SAA).

CAUTION

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

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

Round pressure terminal

Connect same thickness

wiring to both sides.

It is forbidden to

connect two to one

side.

It is forbidden to

connect wiring of

different thicknesses.

- 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.
