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 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.
