Safety Precautions
Symbols in this Use and Care Manual are interpreted as shown below.
Be sure not to do.
Pay attention to such a situation.
Grounding is essential.
Be sure to follow this instruction.
Keep the power supply
circuit breaker or plug
from dirt. Connect the
power supply cord to it
firmly and correctly, to
prevent an electric shock
or a fire break-out due to
insufficient contact.
Do not tangle, pull or press
the power supply cord,
as this cord will be
damaged. An
electric shock or fire
is sometines caused
by a broken power
supply cord.
Never insert a stick or similar obstacle
to the unit. When
the fan rotates at high
speed, this may
cause an injury.
Do not repair the appliance by yourself.
If this is done incorrectly,
it may cause an electric
shock, etc.
When a malfunction occurs
turn off the appliance by
using the remote controller first
before cutting off power supply.
It is harmful to your health if the cool air
reaches you for a long period. It is
advisable to allow the
air flow to circulate
in the room freely.
Prevent the air flow from
reaching the gas burners
and stoves.
Do not touch the operation buttons
when your hands are wet.
Notes:For the purpose of innovation and improvement , above products are subject to change without prior notice.
Do not put any
object on the
outdoor unit.
It is the user's responsibility
to call a registered
technician to ground
the appliance according
to local codes or
ordinances

Use correct power supply in accordance with the
rating plate requirement.
If the supply cord is damaged,it must be replaced
by the manufacturer,its service agent or similarly
qualified persons in order to avoid a hazard.
Remove the power source plug from a socket.
Do not wash the air conditioner with water.
It could cause electric shock.
Do not put anything on the unit,
especially vases which contain
water inside.
If water gets into the unit,the electrical
insulation would be deteriorated
and this could cause electric
shock.
When operating the system simultaneously
with a combustion apparatus,you should
introduce fresh air frequently.
Insufficient
ventilation could
cause an oxygen
deficiency accident.
Trouble shooting should be
done only by an
accredited technician.

o
Outdoor air temperature is over 52c
o
Room temperature is below 21c
o
Room temperature is below 18c
If all operation has stopped, press ON/OFF
button again to restart.
Timer should be set again if it has been
canceled.
Install the air conditioner at a place that
can bear its weight in order to operate
more quietly.
Install the outdoor unit at a place where
the air discharge and the operation noise
would not annoy your neighbors.
Do not place any obstacle in front of the
air outlet of the outdoor unit for it increases
the noise level.
Protection
Features of protector Inspection
After using for a long time, the air conditioner
should be inspected on the following items:
Overheat of the power supply cord and plug
or even a burned smell.
Abnormal operating sound or vibration.
Water leakage from indoor unit.
Metal cabinet electrified.
Stop the air conditioner if above trouble occurs.
It is advisable to have a detailed inspection after
using it for 5 years even if none of the above occurs.
The protective device will work as follows:
Delays the compress start-up for 3 minutes after
restarting the unit or changing mode during
operation.
Delays start-up for 20 seconds after hours of
non operation.
If the air conditioner runs in COOLING or DRY mode with
the door or window opened for a long time ago when relative
humidity is above 80%,dew may drip down from the outlet.

Trouble Check
Does not run
No cooling air
Ineffective control
Does not operate
immediately
Peculiar odor
A sound of
flowing water
Cracking sound is
heard
Spray mist from
the outlet
If the air filter is dirty.
If the intakes and outlets of the air conditioner are
blocked.
If the temperature is not set properly.
If circuit breaker tripped or if the fuse is blown.
If batteries in the remote controller is already drained.
If the protective device works to protect the appliance.
The following cases may not always be a malfunction, please check it before asking for service.
If strong interference(from excessive static electricity
discharge, power supply voltage abnormality)is present,
operation will be abnormal. At this time, disconnect from
the power supply by turning off the circuit breaker and
connect back 2-3 seconds later.
Changing mode during operation will delay
start-up for 3 minutes.
This odor may come from another source
such as furniture, cigarette etc, which is
sucked into the unit and is blown out with the air.
Caused by the flow of refrigerant in the
air conditioner. This is not a problem.
The sound may be generated by the expansion
or contraction of the front panel due to change
of temperature.This is not a problem.
Mist appears when the room air becomes
very cold because of cool air discharged
from indoor unit during COOLING or DRY
operation mode.
Troubleshooting

does not function correctly
If the distance is obscured between the remote
controller and the unit.
Are the batteries exhausted? Replace them with new
ones,and repeat the operation again.

How to Purge Air Tubes
Please read this manual before installing and using it.
Do not let air enter the refrigeration system or discharge refrigerant when moving the air conditioner.
Test run the air conditioner after finishing installation, and record details of operation.

rating 3.15 A,250V.
,18K, 24K
T,
The fuse for the whole unit is to be provided by the user according to the current at maximum power
input or use other over-current protective device instead.
Installation Instructions
Accessibility to the plug must be guaranteed even after the installation of the appliance to disconnect
it in case of need. If not possible, connect appliance to a double-pole switching device with contact
separation of at least 3 mm placed in an accessible position even after installation.
NOTE
Test Running
Connect to the power source, check if the function selection keys on the remote controller are working
properly.
Check if the room temperature adjustments and timer settings are working properly.
Check if the drain is smooth.
Check if there is any abnormal noise or vibration during operation.
Check if there is leakage of refrigerant.
ATTENTION:
If there is no power plug along with the air conditioner,the power cord should be connected to an air
switch ,whose current carrying capacity should be more than 20A and the minimum open-circuit
distance among the live polar pole,the neutral polar pole and the ground polar pole should be more
than 3mm.For any malfuctions,please cut off the supply by the air switch and contact the manufacturer
or its service agent.
The appliance shall be installed in accordance with national wiring regulations.
If the supply cord is damaged. it must be replaced by the manufacturer or its service agent or a
similarly qualified person in order to avoid a hazard.
The security out static air pressure for our products is 0.8-1.05 * standard pressure.
The biggest length for our connection pipe can be 15m. More 20 g refrigerant is
necessary for per miter if the length is over 7 M. The biggest diversity for altitude
between indoor and outdoor unit is 5m.
Please do not place valuable things under the unit after installation.
