NOTE:
Dirty or clogged coils will reduce the operating efficiency of the system and cause higher operating costs. When the air conditioner is not going to be used for a long time.
When air conditioner is not going to be used for a long time
Operate the air conditioner on Air circulation mode (Refer to page 14) for 2 to 3 hours.
• This will dry out the internal mechanisms.

Dirt may collect and may cause a fire.
Remove the batteries from the remote control.
When the air conditioner is to be used again.
Clean the air filter and install it in the indoor unit. (Refer to page 16 for cleaning filters.)
Check that the air inlet and outlet of the indoor/outdoor unit are not blocked.
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.
