Maintenance and Service
Outdoor Unit
The heat exchanger coils and panel vents of the outdoor unit should be checked regularly.
If clogged with dirt or soot, the heat exchanger
and panel vents may be professionally steam cleaned.
Dirty or clogged coils will reduce the operating efficiency of the system and cause higher operating costs.
NOTE
Operation Tips!
Self-Diagnosis Function
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 in operation.
Keep the room temperature
uniform.
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.
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.
Use high fan speed
for effective and fast
cooling.
The unit gives its rated
cooling capacity when the
fan speed is high.
