Maintenance and Service
CAUTION CAUTION
When the air conditioner is not going to be used for a long time.
Operation Tips
Operate the air conditioner on Air
circulation mode for 2 to 3 hours.
• This will dry out the internal mechanisms.
When air conditioner is not going to be
used for a long time.
When the air conditioner is used again.
Turn off the circuit breaker.
Remove the batteries from the remote
controller.
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.
Clean the air filter and install it in the
indoor unit.
(Refer to page 13 for cleaning filters.)
Check that the air inlet and outlet of the
indoor/outdoor unit are not blocked.
Check that the ground wire is
connected correctly. It may be
connected to the indoor unit side.
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 as much as 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
reduces the airflow and lowers
the cooling and dehumidifying
effects. Clean at least once in
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.
