When air conditioner is not going to be used for a long time.
Turn off the circuit breaker, and disconnect the plug.
CAUTIONI
Turn off the circuit breaker when the air conditioner is not going to be used for a long time.
Dirt may collect and may cause a fire.
Remove the batteries from the remote control.

<![endif]>ENGLISH
Operation Tips
Do not overcool the room. 
This is not good for the health and wastes electricity.
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.
Keep blinds or curtains closed.
Do not let direct sunshine enter the room when the air conditioner is in operation.
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.
Keep the room temperature uniform.
Adjust the vertical and horizontal airflow direction to ensure a uniform temperature in the room.
Ventilate the room occasionally.
Since windows are kept closed, it is a good idea to open them and ventilate the room now and then.
