Care and maintenance
When the air conditioner is not going to be used for a long time.
When air conditioner is not going to be used for a long time.
Operate the air conditioner on Air circulation mode for 2 to 3 hours.
• This will dry out the internal parts.
Turn off the circuit breaker.
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.
When the air conditioner is to be used again.
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.
Keep blinds or curtains
closed.
Do not let direct sunshine enter
the room when the air conditioner
is operation.
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.
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.
Ventilate the room
occasionally.
Since windows are kept closed, it
is a good idea to open them and
ventilate the room now and then.
