used for a long time.

unit.
(Refer to page 23~25for cleaning filters.)
1. Operate the air conditioner on Air circulation
mode (Refer to page 21) for 2 to 3 hours.
• This will dry out the internal mechanisms.
2. Turn off the circuit breaker, and disconnect
the power cable.
2. Check that the air inlet and outlet of the
indoor/outdoor unit are not blocked.
CAUTION: Turn off the
circuit breaker when the

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 if 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.
