Fault Cause analysis
Air conditioner does not run upon

To protect the air conditioner upon immediate restart
after a stop, the microcomputer controller will delay the
unit for 3 minutes before the air conditioner will run.

bad smell accumulated from environment. Solution:

You may hear "water flowing" noise
when the
air
conditioner is running.
When
the air conditioner is started, or the compressor is
started or stopped during running or the air conditioner is
stopped, sometimes you may hear "hua-hua" or "di-du-
di-du" noise. This is the flowing sound of refrigerant
other than fault.
Sometimes a thin fog will flow out of
the
outlet
when air conditioner is
running in cooling mode.
This might occur when indoor temperature
and
humidity
are high. This is because the indoor air is quickly cooled
down.
After a period of time, the fog will disappear with the
decrease of indoor temperature and humidity.
You may hear a slight crack when the
air conditioner is started or stopped.
This is the sound of friction caused by expansion
of
panel
or other parts due to the change of temperature.
