8-2-1. Items to be checked first
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.
NO Operation of air conditioner
1 The STD OPERATION indication LED blinks when a
power plug of the indoor unit is plugged in for the first time.
2 In a COOL operation mode, the compressor does not operate
at a room temperature higher than the setting temperature that the
IN DOOR 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.
3 Fan speed setting is not allowed in AUTO(
4 Compressor stops operation intermittently in DRY(
5 Compressor of the outdoor unit is operating although it is turned off
in a HEAT mode.
6 Timer LED of the indoor unit lights up and the air conditioner does
not operate.
7 The compressor and indoor fan stop intermittently in HEAT mode.
8 Indoor fan and outdoor fan stop operation intermittently in
a HEAT mode.
9 The compressor stops intermittently in a COOL mode or DRY
mode, and fan speed of the indoor unit decreases.
4) Indoor unit observes operation condition of the air conditioner, and displays self diagnosis details on the display panel.
Indoor unit room temperature sensor error(open or short)
Indoor unit heat exchanger temperature sensor error(open or short)
Indoor fan motor malfunction
EEPROM error

(7K/9K)
Explanation
It indicates power is on. The LED stops blinking if the operation 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 contin-
ues 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/out-
side air temperature.
