Whenever you press the button, the set Option will be displayed.
Step 4 : Pressing the ON/OFF button ( )
When pressing the operation ON/OFF key with the direction of remote controller for unit, the sound "Ding" is heard and the
OPERATION LED lamp is flickering at the same time, then the input of option is completed. (If the "ding" sound isn't heard,
try again pressing the ON/OFF button.)
Step 5 : Unit operation test-run
First, Remove the battery from the remote controller.
Second, Re-insert the battery into the remote controller.
Third, Press ON/OFF ( ) key with the direction of remote controller for set.
• Error Mode
1st
If all lamps of indoor unit are flickering, Plug out, plug in power plug again and press ON/OFF key to retry.

Check the basic items first to judge if the problem was caused by breakdown or misuse. If none of the basic items are related to the
problem, please scrutinize the machine according to the 'Breakdown Diagnosis by Symptoms' method.
1. The input voltage should be rating voltage ±10% range.
The airconditioner may not operate properly if the voltage is out of this range.
2. Is the link cable linking the indoor unit and the outdoor unit linked properly?
The indoor unit and the outdoor unit shall be linked by 5 cables.
Check the terminals if the indoor unit and outdoor unit are properly linked by the same number of cables.
Otherwise the airconditioner may not operate properly.
3. When a problem occurs due to the contents illustrated in the table below it is a symptom not related to the malfunction of the
airconditioner.
5. Troubleshooting
5-1 Basic Breakdown Diagnosis Items
The OPERATION indication LED(GREEN) blinks when a
power plug of the indoor unit is plugged in for the first time.
In a COOL operation mode, the compressor does not
operate at a room temperature higher than the setting
temperature that the INDOOR FAN should operate.
In a HEAT operation mode, the compressor does not operate
at a room temperature lower than the setting temperature
that indoor fan should operate.
Fan speed setting is not allowed in DRY( ) mode.
Compressor stops operation intermittently in DRY( )
mode.
Compressor of the outdoor unit is operating although it is
turned off in a HEAT mode.
Timer LED(GREEN) of the indoor unit lights up and the
air conditioner does not operate.
The compressor and indoor fan stop intermittently in
HEAT mode.
Indoor fan and outdoor fan stop operation intermittently
in a HEAT mode.
The compressor stops intermittently in a COOL mode or
DRY mode, and fan speed of the indoor unit decreases.

Operation of air conditioner Explanation
It indicates power is on. The LED stops blinking if the opera-
tion ON/OFF button on the remote control unit is pushed.
In happens after a delay of 3 minutes when the compressor
is reoperated. The same phenomenon occurs when a power
is on.
As a phenomenon that the compressor is reoperated after a
delay of 3 minutes, the indoor fan is adjusted automatically
with reference to a temperature of the air blew.
The speed of the indoor fan is set to LL in DRY mode.
Fan speed is selected automatically in AUTO mode.
Compressor operation is controlled automatically in DRY
mode depending on the room temperature and humidity.
When the unit is turned off while de-ice is activated,
the compressor continues operation for up to 9 minutes
(maximum) until the deice is completed.
Timer is being activated and the unit is in ready mode.
The unit operates normally if the timer operation is cancelled.
The compressor and indoor fan stop intermittently if room
temperature exceeds a setting temperature in order to protect
the compressor from overheated air in a HEAT mode.
The compressor operates in a reverse cycle to remove
exterior ice in a HEAT mode, and indoor fan and outdoor fan
do not operate intermittently for within 20% of the total heater
operation
The compressor stops intermittently or the fan speed of the
indoor unit decreases to prevent inside/outside air frozen
depending on the inside/outside air temperature.

5-3-7 Room Pipe sensor failure
1. Check the assembly condition of the sensor connector(CN43) on the indoor unit Main PCB and if not assembled, reassemble the
connector accurately.
2. Detach the room pipe sensor connector(CN43) and check the resistance between connector 3 and 4.
If the above data is not met, replace the room pipe sensor.
3. Assemble the room pipe sensor to PCB, plug in, and check the voltage of connector 3 and 4. If the resistance is below 0.5V or
over 4.9V, replace the indoor Main PCB. (short or disconnected in the PCB board)
5-3-8 When the remote control is not receiving.
1. Check if the connector was normally assembled.
2. Put the set in operation and check the voltage of No. 3(+) and No. 2(-) of the main PCB CN91 while operating the
remote control. When the voltage descends below 3V, the assembly module PCB is normal and the main PCB is poor.
Then replace the main PCB.
3. Replace the assembly display PCB because the module PCB is poor if the voltage between No. 2~3 of CN91
maintains 5V after the remote control starts operation.

and GND of IC02(KA78L05) DC5V ±0.5V?
Checking the power voltage.
1) Check the voltage of the relay(RY71) coil(IC05 PIN
#11 and GND : 0V, PIN#6 and GND : 5V) during
operation(3 minutes after TURBO operation).
2) Check the voltage of both terminals of
terminal block 1 and N(1) after 3 minute
operation.: AC220V
1) Is the voltage over AC180V being imposed
on terminal #3 and #5 of the fan motor
