TIPS FOR SAVING ENERGY

ENGLISH

• Do not cool excessively indoors. This may be harmful to your health and may consume more elec-

tricity.

• 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 condition-

er 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.

Wired remote controller installation

- Since the room temperature sensor is in the remote controller, the remote controller box should

be installed in a place away from direct sunlight, high humidity and direct supply of cold air to

maintain proper space temperature. Install the remote controller about 5ft(1.5m) above the floor

in an area with good air circulation at an average temperature.

Do not install the remote controller where it can be affected by:

- Drafts, or dead spots behind doors and in corners.

- Hot or cold air from ducts.

- Radiant heat from sun or appliances.

- Concealed pipes and chimneys.

- Uncontrolled areas such as an outside wall behind the remote controller.

- This remote controller is equipped with a seven segment LED. display. For proper display of the

remote controller LED's, the remote controller should be installed properly as shown in Fig.1.

(The standard height is 1.2~1.5 m from floor level.)
