So there is no need of activating this function by pressing any key or button.
In the initial mode, the fan operates at a low speed and the compressor starts about 3 minutes later.
As the compressor starts, the fan speed also resumes its previous setting mode.
CAUTION: In case of absence for a long time while power failure, turn off
main power to avoid undersired Auto restart.
Helpful information
Fan speed and cooling capacity.
The cooling/heating capacity indicated in the specification is the value when the fan speed is set to high,
and the capacity will be lower at low or medium fan speed.
High fan speed is recommended when you wish to cool/heat the room quickly.

When air conditioner is not going to be
used for a long time.
1
Operate the air conditioner on Air
circulation mode (Refer to page 20) for 2
to 3 hours.

CAUTION: Turn off the circuit breaker
When the air conditioner is to be used again.
1
Clean the air filter and install it in the
indoor unit.

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.
