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.

ENGLISH

CAUTION

• 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 ceiling.

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 cook-

ing 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.

- Remove the rubber stopple before connecting drain hose.

- Hook on the bracket after connecting the drain hose as below.

Drain piping

- The drain hose should point downward for easy drain flow.

- Do not make drain piping like the following.

Do not raise

Water leakage

Less than 50 mm gap

Drain test

Use the following procedure to test the drain pump operation:

Downward slope

- Set the air direction louvers up-and-down to the position(horizontally) by hand.

- Pour a glass of water on the evaporator using a kettle.

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:

Fastening band

Refrigerant piping

Indoor unit

Thermal insulator

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

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