When the air conditioner is not going to be used for a long time.
Operation Tips
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.
2. Turn off the circuit breaker, and disconnect
the power cable.
When air conditioner is not going to be
used for a long time.
When the air conditioner is to be used again.
3. Remove the batteries from the Remote
Controller.
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.
1. Clean the air filter and install it in the indoor
unit.
(Refer to page 22 for cleaning filters.)
2. Check that the air inlet and outlet of the
indoor/outdoor unit are not blocked.
Do not overcool the room.
This is not good for the health
and wastes electricity.
Make sure that the doors
and windows are shut tight.
Avoid opening doors and
windows if possible to keep the
cool air in the room.
Keep blinds or curtains
closed.
Do not let direct sunshine enter
the room when the air
conditioner is in operation.
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.
Keep the room temperature
uniform.
Adjust the vertical and
horizontal airflow direction to
ensure a uniform temperature in
the room.
Ventilate the room
occasionally.
Since windows are kept closed,
it is a good idea to open them
and ventilate the room now and
then.
