Operation Tips
Operation for comfort and economy
Do not overcool the room
temperature. This is not good
for health and wastes electricity.
Keep blind or curtains closed.
Do not let sunshine enter the
room directly when the air con-
dition is in operation.
Keep the room temp. uniform.
Adjust the vertical and horizon-
tal airflow direction to ensure a
uniform temperature in the room.
Air can’t be discharged to the di-
rection of air-in.
Make sure that the doors and win-
dows are tightly closed.Avoid open-
ing doors and windows as much as
possible to keep air conditioning in the
room.
Clean the air filter regularly.
Blockages in the air filter re-
duce dehumidifying effects.
Clean the air filter 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.
When starting the unit, curtains or
windows should be closed to pre-
vent the heat/cool leakage.
