9. TROUBLE SHOOTING
Don’t try to repair the air conditioner by yourself. It may cause an
electric shock and kill you or damage the unit. Contact authorized service center.
Following checks prior to contact may save you money
Fault Cause analysis
Air conditioner does not run upon
immediate restart after a stop

Breaker switched off or power cut-off ?
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.
Air conditioner starts and stops again
immediately
Inlet or outlet vents blocked ?
Air conditioner blows out bad smell
when it
is initially started.
The air conditioner itself has no bad smell. lf any, is the
bad smell accumulated from environment. Solution:
Clean the air filter . lf still any problem, the air
conditioner shall be cleaned (Please contact Authorized
Service Center)
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.
Air conditioner does not run.

Check if power failure?
Has circuit protection device has tripped?
ls the voltage too high or too low? (To be tested by
professional technicians).
