2	TIPS FOR SAVING ENERGY

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.

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.

Piping material: Polyvinyl chloride pipe VP-25 and pipe fittings

-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.

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.

- 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:

Indoor	Refrigerant
unit	piping
	Thermal insulator
	(accessory)

-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.

! CAUTION

The supplied flexible drain hose should not be curved, neither screwed. The curved or screwed hose may cause a leakage of water.

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.

Connect same thickness wiring to both sides.

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

! CAUTION

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

-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.
