Operating Instructions

1. AUTO MODE : In this mode, operation mode(COOL,

HEAT) is selected automatically by the room temperature

of initial operation.

∆T= -1°C, -2°C, 0°C, +1°C, +2°C

∆T is controlled by setting temperature up/down key of

remote control

2. COOL MODE : The unit operates according to the

difference between the setting and room temperature.

(18°C~30°C)

3. HEAT MODE : The unit operates according to the

difference between the setting and room tempera-

ture.(16°C~30°C)

*Prevention against cold wind : In order to prevent the

cool air from flowing out at the heat mode, the indoor fan

does not operate or operates very slowly in the

following cases. At this time, the indoor heat exchanger

will be preheating.

- For 3~5 minutes after the initial operation

- For deicing operation

- The operation of an indoor fan in accordance with

the temperature of an indoor heat exchanger

*High temperature release function : It is a function to

detect an outdoor overload by the sensor of an indoor

heat exchanger and to turn the outdoor fan or the

compressor ON/OFF for safety.

*Deice : Deicing operation is controlled by indoor unit's

heat exchanger temperature and accumulating time of

compressor's operation.

Deice ends by sensing of the processing time by deice

condition.

4. DRY MODE : Has 3 states, each determined by room

temperature.

The unit operates in DRY mode.

*Compressor ON/OFF Time is controlled

compulsorily(can not set up the fan speed, always

breeze).

*Protective function : Low temperature release.

(Prevention against freeze)

5. TURBO MODE : This mode is available in AUTO, COOL,

HEAT, DRY, FAN MODE.

When this button is pressed at first, the air conditioner is

operated "powerful" state for 30 minutes regardless of the

set temperature, room temperature.

When this button is pressed again, or when the operating

time is 30 minutes, turbo operation mode is canceled and

returned to the previous mode.

*But, if you press the TURBO button in DRY or FAN

mode that is changed with AUTO mode automatically.

6. SLEEP MODE : Sleep mode is available only in COOL or

HEAT mode.

The operation will stop after 6 hours.

*In COOL mode : The setting temperature is automatical-

ly raised by 1°C each 1hour When the temperature has

been raised by total of 2°C, that temperature is

maintained.

*In HEAT mode : The setting temperature is automatically

dropped by 1°C each 1hour.

When the temperature has been dropped by total of

2°C, that temperature is maintained.

7. FAN SPEED : Manual (3 step), Auto (4 step)

Fan speed automatically varies depending on both the

difference between setting and the room temperature.

8. COMPULSORY OPERATION :

For operating the air conditioner without the remote

control.

*The air conditioner starts up in the most suitable mode

for the room temperature:

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.

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 case of heat pump model]

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.

Timer LED(GREEN) of the indoor unit lights up and the

air conditioner does not operate.

The compressor stops intermittently in a COOL mode or

DRY mode, and fan speed of the indoor unit decreases.

[In case of heat pump model]

Compressor of the outdoor unit is operating although it is

turned off in a HEAT mode.

[In case of heat pump model]

The compressor and indoor fan stop intermittently in

HEAT mode.

[In case of heat pump model]

Indoor fan and outdoor fan stop operation intermittently

in a HEAT mode.

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.

Timer is being activated and the unit is in ready mode.

The unit operates normally if the timer operation is cancelled.

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.

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.

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

Troubleshooting

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)

Troubleshooting

6-2-8 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.
