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 32mm.

Piping material: Polyvinyl chloride pipe VP25 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 300mm from the 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:

Fastening band (accessory)

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.
