Warning for installation
Entrusted Installation
Installation of the machine should
be entrusted to certified person of
after service. Unauthorized install-
ation may cause water leakage,
electric shock or fire hazard for
improper operation.
To prevent leakage of refrigerant,
let certified person of after service
do it.
Leakage of refrigerant over certain
consistence may result in shortage
of oxygen. Enough precautions
MUST be done to avoid oxygen
shortage in case of refrigerant lea-
king if the room where the air-
conditioner is installed is small.
The power supply must be fitted with
earth line to ensure valid earthing of
the air-conditioner. No or incomplete
earthing connection may cause the
risk of electric shock.

Important Points of Safety
Attention
Attention points for use
lEnsure ventilation of the room
if the machine is used with
burning facilities. Deficient
ventilation can cause oxygen
shortage.
lCheck whether installation
bench of the machine is
damaged after a long period
of use. Machine on damaged
bench may fall down and cause
human injury or other damage.
lIn place where winds produced
by the machine can reach, don’t
lay any animals or plants which
may be hurt otherwise.
l Don’t put vases containing water
or other else on the unit assembly.
Otherwise, the machine may be
immersed internally and result in
bad electric insulation causing
electric shock.
l The is machine CANNOT be
used for the purpose of prese-
rving food, animals, plants,
precision instruments and
artwork etc., which may be
destroyed otherwise.
l DON’T replace fuse with ma-
terial other than fuse of proper
capacity. Replacing fuse with
metal wire or copper etc. can
cause fire hazard or other faults.
l DON’T lay any burning facilities
in place where winds produced by
the machine can reach. Incomplete
combustion of burning facility may
be caused otherwise.
l DON’T clean the machine with
water. Electric shock may occur
otherwise.
l DON’T put flammable spray
articles nearby or spray them to
the machine. Fire hazard may
occur otherwise.
l DON’T operate switch with wet
hand. Electric shock may occur
otherwise.
l Stop operation and shut down
manual power switch before
cleaning and maintenance.
l The power supply MUST be of
rated voltage and connected with
special electrical supply circuit.

Trouble Shooting
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 con-
densate water mist caused by sudden co-
oling 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.
Trouble Shooting
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 couldn't 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?

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?
If,after the above checks and the corresponding corrective actions,the system remains
abnormal operation,or the following facts appear, please turn off the air conditioner and
then contact the local authorized service center.
Frequent open of fuse or breaker.
There is water leakage during COOL or DRY operation.
The operation is abnormal or abnormal sound is heard.
