Operation Tips
• Do not overcool the room.
− This is not good for the health and wastes
electricity.
• Keep blinds or curtains closed.
− Do not let direct sunshine enter the room when
the air conditioner is in operation.
• Keep the room temperature uniform.
− 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.
− Avoid opening doors and windows as much as
possible to keep the cool air in the room.
• Clean the air filter regularly.
− Blockages in the air filter reduce the airflow and
lower cooling and dehumidifying effects. Clean
at least once every two weeks.
• Ventilate the room occasionally.
− Since windows are kept closed, it is a good idea
to open them and ventilate the room now and
then.
