Safety Precautions
Please read the following notices before operation
WARNING
If there’s abnormal pheno-
menon (like smell of burning),
please cut o the power im-
mediately and then contact
with authorized maintenance
center.
The special circuit must be
adopted for power supply to
avoid re.
Before cleaning the air condi-
tioner, please cut o the power.
Power supply should adopt the
special circuit with the protec-
tion of air switch and the capac-
ity must be sucient.
Pease do not turn on or turn o
the air conditioner frequently.
Y-type connection is adopted
for the power supply of this air
conditioner.If the power cord is
damaged, it must be replaced
by the manufacture, mainte-
nance center or a similarly qual-
ied person to avoid a hazard.
When the voltage is too high,
electric elements can be dam-
aged easily; if the voltage too
low, the compressor will vibrate
ercely, which may damage the
cooling system or compressor
and electric components can’t
operate.
Otherwise, it will cause electric
shock or injury.
cut o power
Do not use octopus multipur-
pose socket or mobile wiring
board for wire connection.
Please cut o the power supply
when the air conditioner won’t
be used for an extended period
of time.
Do not damage the power cord
or use unspecied power cord.
Otherwise, it may cause re due
to overheating of power cord.
Otherwise, it will accumulate
dust and it may cause overheat-
ing, re and other accidents.
Do not operate the air condi-
tioner with wet hands.
Do not cut o or damage the
power cord or signal control
wire. If the power cord or signal
control wire of air conditioner
is damaged,please replace it by
the professional with specied
power cord.
Otherwise, it may cause electric
shock.
If this abnormal status is kept on,
air conditioner may be damaged
or even cause electric shock or
 r e .

Safety Precautions
Always ensure eective
earthing.
Do not keep windows and
doors open for a long time
during operation.
Install the outdoor unit
rmly enough.
Do not step on the top of the
outdoor unit or place heavy
things on it.
Do not attempt to repair the
air conditioner by yourself.
Do not block the air inlet or
outlet.
Keep combustible materials
away from the units at least
1m.
For safety,be sure to turn o
the circuit beaker before per-
forming any maintenance or
cleaning or when the product
is not used for an extended
period of time.
Select the most appropriate
temperature.
No earthing may cause
electric shock.
It will result in insucient
performance
It may cause falling of the unit
and injury to the person.
It may cause damage or injury
Incorrect repairs may cause
electric shock or re. Please
contact the local authorized
service center.
It will result in insucient per-
formance and cause malfunc-
tions.
It may cause re or explosion.
Accumulated dust may cause re
or electric shock.
It can save electric energy.
Keep room
about
5° cooler than
outside.

Safety Precautions
Do not cut o or damage the power cords or
control cords. If they are damaged, please
contact the dealer or qualied service per-
sonnel.
Do not insert your hands or objects into
the air in let or outlet.
Do not expose yourself to cold air directly
for a long time.
Do not splash water on the air conditioner. Do not place a burner near the air conditioner.
Do not use the unit for any other purpose,
such as preserving food or drying clothes.
Do not expose animals or plants directly to
the air ow.
It may cause an accident.
It’s not good for your health.
It may cause electric shock or malfunction.
It will cause CO toxi-
cosis due to incom-
plete burning.
It may have a detrimental eect on them.
To change the airow direction, adjust the
vertical and horizontal air ow direction by
using the remote controller.

Troubleshooting
Caution
The air conditioner is not user serviceable. Incorrect repair may cause electric shock or re so
please contact an authorized service center for professional repair Following checks prior to con-
tact may save your time and money.
The unit does not operate
Odours are emitted
“Water owing”noise
Mist is emitted in COOL mode
Cracking noise
• The unit does not operate if it is turned on im-
mediately after it is turned o.This is to protect
the unit. You should wait about 3 minutes.
• Some odours may be emitted from the indoor
unit. This is the result of room smells (such as
furniture, tobacco, ect.) which have been tak-
en into the air conditioner.
• Consult authorized service center for cleaning
if the odours still exist.
• The swishing noise like water owing is the
refrigerant owing inside the unit.
• During cooling operation, a thin mist may be
seen emitted from the indoor unit due to high
room temperature and humidity.
After a period of time, the mist will disappear
with the decrease of room temperature and
humidity.
• This is the sound of friction caused by expan-
sion and/or contraction of panel or other parts
due to the change of temperature.

Operation Tips
Cooling Operation
Principle:
Air conditioners absorb heat in the room and transmit it to the outdoor unit, so that the room
temperature is decreased. The cooling capacity will increase or decrease according to outdoor
ambient temperature.
Antifreezing Function:
If the unit is operating in COOL mode and in low ambient temperature, frost may be formed on
the heat exchanger. When indoor heat exchanger temperature decreases below zero, compres-
sor will stop operation to protect the unit.
Heating Operation
Principle:
Air conditioners absorb heat from outdoors and transmit it to the indoor unit, increasing room
temperature. The heating capacity will decrease at low ambient temperature.
Defrosting:
When outdoor temperature is low but humidity is high, frost may form on the outdoor unit dur-
ing extended operation, aecting heating eciency. The air conditioner may stop operation
during auto defrosting operation.
During auto defrosting, the fan motors of indoor unit and outdoor unit will stop.
During defrosting, the indoor indicator ashes and the outdoor unit may emit vapor.
This is not malfunction.
After defrosting is nished, the heating operation will recover automatically.
Anti-cold Air Function:
In HEAT mode, the indoor fan will not operate in order to prevent cold air blowing out
(within 2 minutes) if indoor heat exchanger doesn’t reach a certain temperature under the
following three states:
1. Heating operation starts; 2. After Auto Defrosting is nished; 3.Heating at low temperature.
Rest Heat Blow
In the following situations, the indoor unit may still run for some time,
to blow out the rest heat of the indoor unit.
1. In HEAT mode, the temperature reaches the setting value, the compressor stops and the in-
door fan still run for 60s.
2. In HEAT mode, if you turn o the unit, the compressor stops and the indoor fan still run for 10s.

Operation Tips
Operating Temperature Range
Indoor side DB/WB(oC) Outdoor side DB/WB(oC)
Maximum cooling 32/23 43/—
Maximum heating 27/--- 24/18
The operating temperature range (outdoor temperature) for cooling only unit is 10℃~ 43℃
for heat pump unit is -15℃~48℃.
Tips for energy saving:
* Do not overcool or overheat.
Setting temperature at a moderate level helps energy saving.
* Cover windows with a blind or a curtain.
Blocking sunlight and air from outdoors is favorable for cooling (heating).
* Clean air lters once per two weeks.
Clogged air lters lead to inecient operation and energy waste.
Tip for relative humidity:
Condensate water is likely to form at the air outlet if cooling or drying for a long time when the
relative humidity is more than 80% ( with doors and windows open).
