20 Room Air Conditioner
Maintenance and Service
When the air conditioner is not going to be used for a long time.
When the air conditioner is to be used again.
1. Operate the air conditioner on Air circulation
mode (Refer to page 19) for 2 to 3 hours.
• This will dry out the internal mechanisms.
1. Clean the air filter and install it in the indoor
unit.
(Refer to page 20 for cleaning filters.)
2. Turn off the circuit breaker, and disconnect
the power cable.
CAUTION: Turn off the
circuit breaker when the
air conditioner is not
going to be used for a
long time.
2. Check that the air inlet and outlet of the
indoor/outdoor unit are not blocked.
Dirt may collect and may cause a fire.
3. Remove the batteries from the Remote
Controller.
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.
