1. Precautions

1. Warning: Prior to repair, disconnect the power cord from the circuit breaker.

2. Use proper parts: Use only exact replacement parts. (Also, we recommend replacing parts rather than repairing them.)

3. Use the proper tools: Use the proper tools and test equipment, and know how to use them.

Using defective tools or test equipment may cause problems later-intermittent contact, for example.

4. Power Cord: Prior to repair, check the power cord and replace it if necessary.

5. Avoid using an extension cord, and avoid tapping into a power cord. This practice may result in malfunction or fire.

6. After completing repairs and reassembly, check the insulation resistance.

Procedure: Prior to applying power, measure the resistance between the power cord and the ground terminal. The resistance must be greater than 30 megaohms.

7. Make sure that the grounds are adequate.

8. Make sure that the installation conditions are satisfactory.

Relocate the unit if necessary.

9. Keep children away from the unit while it is being repaired.

10. Be sure to clean the unit and its surrounding area.

1. AUTO CHANGEOVER FUNCTION :

*To operate in the “Auto change over” mode, set the MODE on “AUTO”.

*According to the outdoor and indoor temperatures while starting the operation, one of the modes from the cooling, dehumidifying and heating is selected automatically to operate.

*The operation mode shall be set again if the other condition different from that of the operating conditions(cooling, heating, dehumidifying mode) is kept for 60 minutes during the change-over operation.

2. COOL MODE : The unit operates according to the difference between the setting and room temperature.(setting Temp.:

18°C~30°C)

3. HEAT MODE : The unit operates according to the difference between the setting and room temperature.(setting Temp.:

16°C~30°C)

*Prevention against cold wind : For about

3~5 minutes after initial operation (thermo control or “de-ice”), the indoor fan will either not operate or operate very slowly, then switch to the selected fan speed. This period is to allow the indoor unit's heatexchanger to prewarm until emitting warm air.

DB98_08728A(1)_SM_1 12/20/02 3:24 PM Page 3-1

Operating Instructions and Installation

*High temperature release function : The outdoor unit and compressor ON/OFF is controlled for safety operation when heat exchanger of indoor unit is over heated.

*De-ice : Deicing operation is controlled by outdoor unit's heat exchanger temperature and accumulating time of compressor's operation.

De-ice ends by sensing of the processing time by de-ice Condition.

*According to the difference between the set temperature (Ts) and indoor temperature (Tr), the operation frequency of compressor is controlled as each area.

(Cooling area/COMPor ON/OFF area/Monitoring area)

➟ Cooling area : same as the cool mode

➟ COMPor ON/OFF area : repeat of

COMPor frequency 36[Hz] for 4 minutes operation/0[Hz](off) for 6 minutes

➟ Monitoring area : COMPor off.

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 in “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, it is changed into

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 automatically 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 droped by 1°C each

1hour.

When the temperature has been droped by total of 2°C, that temperature is maintained.

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

Fan speed automatically varies depending on the difference between setting and the room temperature.

8. COMPULSORY OPERATION :

For operating the air conditioner without the remote controller, the tact key in indoor unit can be used.

When started with this key, the mode is set on “AUTO”.

The operating is the same function as

AUTO MODE in the remote controller.

Each time you press this key, 5WAY function is changed in the following order;

STD(standard) ➝ NATURE ➝

POWER(High-speed) ➝ Saving(Power-

Saving) ➝ SILENCE

❊ STD(standard)( ) : General operation

Mode

❊ NATURE( ) : The unit is operated according to health pattern control

❊ POWER( ) : The unit is operated in powerful state

❊ SAVING( ) : The unit is operated in power saving state

❊ SILENCE( ) : The unit is operated quitely

Each mode has Auto(Cool or Heat) operation designed in advance.

9. SWING : BLADE-H is rotated vertically by the stepping motor.

*Memory louver : When ON/OFF button is pressed at stop state, the BLADE-H returns to its original location which is operating state before stop.

5. Troubleshooting

Since the inverter air conditioner is equipped with Electrical control circuits at both Indoor & outdoor unit, the trouble shooting shall be performed according to the error mode.

Inside the controller of the outdoor unit (inverter), the large capacity of electrolytic condenser so that it takes the time to discharge after the power off since the electrical charge remains

(the charging voltage DC 340V).

Take care of the electrical shock by contact on the charging part before the discharge after the power off. (It takes approximately 2 minutes to discharge).

5-1 Basic items for trouble shooting

1) Is the power source proper?

The power source shall be in the range of the rated voltage

±10%

. If it is out of this range, it may cause the abnormal operation.

2) Is the connection made between the indoor and outdoor unit?

The connection between indoor and outdoor unit shall be performed with 4 wire. (connection cable of indoor and outdoor unit + ground wire).

3) The phenomena as follows are not out of order.

NO

1

Phenomena

The operation is not done.

Cause and reason

•

Is the power off or the power unplugged?

•

Does it stop because it is the completion time?

•

Unplug and plug again the power source for 2 minutes.

2 The wind comes out but the heating/cooling is not performed.

•

Is the filter clogged with dust or dirty?

•

Is there any direct light on the outdoor unit or any obstacle against it?

•

Is the selected temperature too high? Lower the selected temperature lower than the current one (during cooling).

•

Is the selected temperature too low? Raise the desired temperature than the current one (during heating).

•

Is the “Fan only Mode” operation?

3 The remote controller does not operate.

•

Is the battery run out?

•

Is the battery inserted in the wrong way(+, -)?

•

Is the detection part of the indoor unit blocked?

•

Does it interfered with the radio of neon sign?

4 The wind volume is not adjusted.

•

Is the operation selected among one of Auto / Dry / Turbo / Sleeping?

•

The temperature setting is not required since the wind volume set automatically.

•

Check again at the state of Cooling / Fan only / Heating.

5 The temperature is not set.

•

Is the operation selected among the Dry / Turbo / Sleeping / Fan only Mode.

•

Since the temperature is automatically set, the temperature setting is not required.

•

Check again at the cooling/heating state.

•

The standard temperature ±2˚C during the automatic operation.

6 The operation lamp continues to be flickering.

•

Push the Operation / Stop button.

•

Unplug and plug the power source.

7 The immediate operation starts without control of remote controller when plugged

•

It is the case that the auto restart function works.

# Auto restart function is the convenient function where the operation state is memorized in the Memory IC during the blackout and the operation restarts when the power comes back.
