Trouble-shooting

Air conditioner dose not
operate at all.

* Is there a power failure?
* Is the plug out?

* I

s 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.

Cool or heat efficiency is

not good.

Foggy air
flows out.

The air conditioner opera-
tion is noisy.

It seems that condensation is leaking from air conditioner.

Air conditioner dose not operate for about 3

minutes when restart.

Please check the following items before asking for repair,it saves your time and
money.
