Trouble-shooting
* Is there a power failure?
* Is the plug out?
* Is power fuse or switch off ?
* Whether the voltage is too high or too low?
* Is air inlet or outlet locking?
* Is there any other heat/cool source in room?
* Are air filters dirty very much?
* Is indoor fan speed set at LOW?
* Maybe the room is too hot/cool when the unit is
started.
* At COOL mode operation, sometimes there is foggy
air flowing out of indoor unit, this is because the room
humid air has been cooling rapidly.
* The unit is normal while the indoor outlet is sending
out some odor, because the inlet air may be mixed
with the smell of furniture and smoke.
* For a noise that sounds like water flowing:
This is the sound of freon flowing inside the air con-
ditioner unit.
* For a noise that sounds like a shower:
This is the sound of the dehumidifying water being
processed inside the air conditioner unit.
* Condensation occurs when the airflow from the air
conditioner cools the warm room air.
* This is to protect the mechanism.
* Wait about three minutes and operation will begin.
