accordance with the rating plate
requirement. Otherwise, serious
faults or hazard may occur or a
fire maybe break out.
Keep the power supply circuit breaker
or plug from dirt. Connect the power
supply cord to it firmly and correctly,
lest an electric shock or a fire break out
due to insufficient contact.

Grounding is essential.
Warning: Incorrect handling could
cause a serious hazard, such as death,
serious injury, etc.

OFF
Do not use the power supply circuit
breaker or pull off the plug to turn it off
during operation. This may cause a fire
due to spark, etc.
Do not knit, pull or press the power supply

Features of protector
The protective device will work at following cases.
Noise pollution
Install the air conditioner at a place that
can bear its weight in order to operate
more quietly.
o
Install the outdoor unit at a place where
the air discharged and the operation noise
would not annoy your neighbors.
Do not place any obstacles in front of the
air outlet of the outdoor unit lest it increases
the noise level.
Restarting the unit at once after operation stops or changing mode during operation, you need to
wait 3 minutes.
Connect to power supply and turn on the unit at once, it may start 20 seconds later.
If all operation has stopped, press ON/OFFbutton again to restart, Timer should be set again
if it has been canceled.
Features of HEATING mode
Preheat
At the beginning of the HEATING operation, the airflow from the indoor unit is discharged
2-5 minutes later.
Defrost
In HEATING operation the appliance will defrost (de-ice) automatically to raise efficiency.
This procedure usually lasts 2-10 minutes. During defrosting, fans stop operation.
After defrosting completes, it returns to HEATING mode automatically.
Note: Heating is NOT available for cooling only air conditioner models.

Troubleshooting
The following cases may not always be a malfunction, please check it before asking for service.
Trouble Analysis
If the protector trip or fuse is blown,please wait
Does not run
No cooling or
heating air
Ineffective control
Does not operate
immediately
3 minutes and start again.The
may be preventing unit from working.
The batteries in the remote control may be dead
Check to see if the appliance is properly plugged in.
Is the air filter dirty?
Are the intakes and outlets of the air conditioner
blocked？
Is the temperature set properly？
Are doors or windows open？
If there is strong interference (from excessive
static electricity discharge or power supply voltage
abnormality), the appliance may operate
abnormally. Disconnect the power supply and
connect back 2-3 seconds later.
Changing mode during operation,3 minutes will
delay.
don't run
protector device
Peculiar odor
A sound of
flowing water
Cracking sound is
heard
Spraying mist from
the outlet
The compressor indicator lights on constantly,
running indicator flashes and indoor fan stops.
This odor may come from another source
such as furniture, cigarette etc, which is
sucked in the unit and blows out with the air.
Caused by the flow of refrigerant in the air
conditioner.Not a cause for concern.
Sound of defrosting during heating mode.
The sound may be generated by the expansion
or contraction of the front panel due to change
of temperature.
Mist appears when the air in the room becomes
very cold. This is because of the cool air
discharged from the indoor unit during COOLING
or DRY modes.
The unit is shifting from heating mode to defrost.
The indicator will light off and return to heating
mode.

Outdoor unit installation
Rubbe r pad ( opt ional )
1. Install Drain Port and Drain Hose (for heat-pump model only)
The condensate drains from the outdoor unit when the unit operates
in heating mode. In order not to disturb your neighbor and protect
the environment, install a drain port and a drain hose to direct the
condensate water. Just install the drain port and rubber washer to
the chassis of the outdoor unit, then connect a drain hose to the
port as the right figure demonstrates.
2. Install and Fix Outdoor Unit
Fix with bolts and nuts tightly on a flat and strong floor.
If installed on the wall or roof, make sure to fix the supporter well to prevent it
from shaking due to serious vibration or strong wind.
3. Outdoor Unit Piping Connection
Remove the valve caps from the 2-way and 3-way valve.
Connect the pipes to the 2-way and 3-way valves separately according to the required torque.

Air purging
The air which contains moisture remaining in the refrigeration cycle may cause a malfunction on the
compressor. After connecting the indoor and outdoor units, release air and moisture from the refrigerant
cycle using a vacuum pump, as shown below.
Note: To protect the environment, be sure not to discharge the refrigerant to the air directly.
