Troubleshooting
The following cases are not troubles.
During operation, the air conditioner may
sometimes exhibit a sound of "clatter" or
"rumble". This is the common sound of
refrigerant flow but not a trouble.
A sound of "Pi-Pa" is generated.
Smells are given off.
During operation, mist or steam are
blown out.
During COOL operation, it automatically
changes to FAN mode.
The system couldnt be re-started immediately
after turning off.The unit can't start?
This is caused by the thermal expansion
or cold shrinkage of plastics.
Sometimes there are smells in the air flow
from the indoor unit. This is caused by the
smell of cigarettes or paint coatings inside
the unit.
During COOL or DRY operation, the unit
may blow out a thin mist. This is the condensate water mist caused by sudden cooling of the indoor air blown out from the
indoor unit.
In order to prevent frost accumulation on
the heat exchanger in the indoor unit,
sometimes it will automatically transfers
to FAN mode, but soon will return to
COOL mode.
This is due to the systems self-protection
function, which prevents it from restarting
in 3 min after stops.
Please wait
for 3 min.
"Hua-Hua"
Water flow sound is heard.
15
Troubleshooting
ON
OFF
During DRY operation, there is no air
sent out or fan speed cant be changed.
In HEAT mode, the outdoor unit
generates water or steam.
This occurs during removal of the frost
(in defrosting operation) on the radiator
of outdoor unit.
Defrost operation
In HEAT mode, the indoor fan still
keeps running even the unit operation
stops.
After the unit stops, the indoor fan will
continue to run for a while to eliminate
residual heat.
Before asking for after-service to an authorized service center, please check your air
conditioner for the following items
The system couldnt start
Is power on/off switched on?
The power on/off switch is
not at position of "ON".
Is the power supply line
normal?
Is current leakage breaker
triggered?
Please do immediately
cut off power supply and
contact the authorized
service center.
Power
failure?
16
When fault occurs
Poor cooling or heating
Is the operation controller
adjusted as required?
Are there any obstructs
before the air inlet or outlet?
Is there any door or window
left open?
Poor cooling
Is there any other heat
source in the room?
Is there any direct sunlight
into the room?
Are there too many people
in the room?
17
When the air conditioner does not operate properly after you have checked the above mentioned items or when the
following phenomenon is observed, stop the operation of the air conditioner and contact your sales dealer.
The fuse or breaker often shuts down.
Water drops off during cooling operation.
There is a irregularity in operation or abnormal sound is audible.
When the CHECK lamp flickers, an irregularity has occurred in the air conditioner.
