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 con-

ditioner 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.
