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 as much as possible
to keep the cool air in the room.
Blockages in the air filter
reduces the airflow and lowers
the cooling and dehumidifying
effects. Clean at least once in
every two weeks.
Since windows are kept closed,
it is a good idea to open them
and ventilate the room now and
then.
