

Squeak may occur when the air conditioner starts or stops running. That is the sound

raised because the plastic assemblies inflate or deflate when the temperature changes.



Dust is blown out of the indoor unit.

When the air conditioner resumes service after a long period out of service, the dust in the

indoor unit will be blown out.



The indoor unit gives out smell.

The indoor unit absorbs the smell of the room, furniture or smoking, and gives it out when

running.



Shift from cooling mode to air supply mode.



In order to prevent frosting of the indoor heat exchanger, the air conditioner shifts to air

supply mode automatically, and resumes to cooling mode in a short time.



When the room temperature decreases to the set temperature, the air conditioner will

shut down the compressor automatically, and shifts to the air supply status. After the

room temperature rises, the compressor will restart. The action of the compressor in

the heating mode is the contrary.

11.2 Faults of air conditioner and cause



If any of the following exceptions occur, operation of the air conditioner will be immediately

stopped. Turn off the power switch, and check it.



The

Run

indicator blinks quickly (2 blinks per second.). After turning off the power

switch and then turning it on again, that indicator still blinks quickly. The receiving

function of the remote controller fails, or the start and shutdown operation is abnormal.



The fuse blows out frequently, or the circuit breaker protection occurs frequently.



Foreign substance or moist enters the air conditioner or other exceptions occur.



If the air conditioner fails but does not meet the foregoing phenomena obviously, check the

system in the following procedure:
