Maintenance and Service
Operation Tips!
When the air conditioner is not going....
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
cooling operation.
Make sure that the doors
and windows are shut tight.
Avoid opening doors and windows
as much as possible to keep the air
conditioned air in the room.
Clean the air filter regularly.
Blockages in the air filter reduce the airflow and lower
air conditioned 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 from time to time.
When it is not going to be used for a long time.
1 Operate the air conditioner on Air circulation mode for 2 to 3 hours.
• This will dry out the internal parts.
2 Turn off the circuit breaker.
CAUTION: 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.
3. Remove the batteries from the Remote Controller.
When the air conditioner is to be used again.
■
Check that the air inlet and outlet of the indoor/outdoor unit are not blocked.
