Dirt may collect and may cause a fire.
Check that the ground wire is
connected correctly. It may be connect
to the indoor unit side.
Helpful information
The air filters and your electiric bill.
If the air filters become clogged with dust, the
cooling capacity will drop, and 6% of the electricity
used to operate the air conditioner will be wasted.
Operation Tips
Do not overcool the room.
Keep blinds or curtains
closed.
Keep the room temperature
uniform.
This is not good for the health
and wastes electricity.
Do not let direct sunshine
enter the room when the air
conditioner is in operation.
Adjust the vertical and
horizontal airflow direction to
ensure a uniform temperature
in the room.
Make sure that the doors
and windows are shut tight.
Clean the air filter regularly.
Ventilate the room
occasionally.
Avoid opening doors and
windows as much as possible
to keep the cool air in the
room.
Blockages in the air filter
reduce the airflow and lower
cooling and dehumidifying
effects. Clean at least once
every two weeks.
Since windows are kept
closed, it is a good idea to
open them and ventilate the
room now and then.

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.
