used for a long time.
Clean the air filter and install it in the indoor
unit.
Turn off the circuit breaker, and disconnect
the plug.
(Refer to page 13 for cleaning filters.)
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.
Check that the air inlet and outlet of the
indoor/outdoor unit are not blocked.
Remove the batteries from the remote
control.
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.
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.
Avoid opening doors and
windows as much as possible
to keep the cool air in the room.
