1. SAFETY CAUTIONS FOR REPAIRING

When you repair the refrigerator, please kindly take care for the following cautions.

1.1 WarningBefore repairing unit, unplug supply cord• Before you repair the refrigerator, please unplug the supply cord.

Use authentic parts when repairing• When you replace the parts, please use authentic parts to replace defective parts.

Caution during brazing• When you use touch for brazing, please ensure ventilation. Otherwise, you will be poisoned by carbon monoxide.

Pay attention to using refrigerant• If refrigerant touches fire, the gas becomes poisonous gas.

Pay attention to getting electricity shock• When you check the voltage of terminal, please do not touch the electricity part terminal.• When you replace the parts, please wait for 3 minutes at least for discharging capacitor.

Check safety after repairing• Check the screws, parts, lead wires to take in place.• Check the repairing portion whether circumferential parts are damaged or not.• Check insulation resistance between supply plug and earth.• When install refrigerator, check condition of supply cord and plug.• Wipe off the dust on plug.• Cutting and seal the electric device carefully.

1.2 CautionWatch the hot parts• During operation and after operation, compressor and pipes are hot.• Also, under these condition, heater are hot.• Do not burn your fingers when you touch it.

Pay attention to refrigerant• Do not touch liquid refrigerant. Otherwise your hands may be burnt.

Pay attention to edge of parts• Otherwise, your fingers may be cut.

Pay attention to fins of evaporator and condenser• Otherwise, your fingers may be cut.

Before transportatin, adjust the bolt• Otherwise, the floor may be damaged.

Do not touch the pipe after brazing• Otherwise, your hands may be burnt.

6. TEMPERATURE CONTROL

How to operate the “QUICK FREEZING” (Quick cool button)

If you want the refrigerator to freeze quickly in order to preserve the food, press the “Quick Freezing” button (green light LED turns on). The system will operate immediately and will stop operating automatically (green light LED turns off) when it runs for 150 minutes.And the operation will return to normal mode.

Remark

• If you want to stop the operation, press the “Quick Freezing” button (green light LED turns off). The system will return to normal mode.• If the green light LED is flashing, it means that the defrosting system is now working. The quick freezing system will start the operation right after the defrosting operation is finished.

How to use the “ENERGY-SAVING” operation

When food storage is small or during nighttime and people out of home (when door opening frequencyis low), the “ENERGY-SAVING” operation saves electricity consumption by operating the compressorat a lower speed than the normal operation.

How to save energy

• Press the “ENERGY SAVING” button. (green light turns on)• Press the “ENERGY SAVING” button again to stop the operation. (green light turns off)

About energy saving

• Deodorizing function reduces.• Interior temperature gets slightly higher.

• The “ENERGY SAVING” operation stops when the power cord is reconnected or after recovering from a power failure.

• When the “ENERGY SAVING” is activated during “QUICK FREEZING”, the “ENERGY SAVING” starts after completing the “QUICK FREEZING”

• Frequent opening of the doors raise the interior temperature. (Higher interior temperature automatically activates normal operation on a temporary basis.)

7. REFRIGERATOR INSTRUCTION GUIDELINE

1. Do not open the refrigerator frequently or leave it open for a long time. This is to prevent water dripping inside the refrigerator which will cause the waste of coolness and consumpting of energy.

2. Do not refrigerate unnecessary items or hard-to-rot foodstuff such as pumpkin, shallot, garlic, potato as it will make the refrigerator to work over load and waste the storage space without necessity.

3. Adjust the temperature according to the actual operating condition for energy saving.

4. Do not refrigerate the bottles bigger than the door shelf or the tray as the door will not close completely, which will cause the leakage of coolness.

5. Frequently check the door opening seal, it must be closed to the refrigerator’s body completely. Do not leave the seal dirty or damaged or deteriorated as the coolness will leak and will cause the consumption of the energy without necessity.

6. If you will not be at home for several days or there are nothing refrigerated in the refrigerator, the plug should be disconnected for energy saving. In this case, clean the refrigerator and leave it half-open to prevent bad odor.

7. Clean the drain tray located over the compressor at the back of the refirgerator every 3 months to prevent the odor generated from humidity.

8. Energy saving dryer pipes and heating pipes embedded around the refrigerator cabinet are helping to prevent “Condensation” on the outer surface of the cabinet without consuming energy. This will make the outer wall of the refrigerator get warm and that is not a malfunction.

9. Drinking water bottles, beverage bottles such as soft drinks and fruit juices should be sealed closely to prevent odor gets into the bottles.

The refrigerator does not operate.

Before calling for servicing, please check as follows.

* Check to be sure that the plug and its socket are in good conditions.* Check that there is any problem on main fuse and electricity system in the house or not.

The cooling does not function properly.

* Check to be sure that the temperature control button is at the proper position.* Check that the refrigerator is overloaded with stuff of there is any hot foodstuff refrigerated in it or not.* Is the refrigerator located exposing directly to sunlight or heat source?* Is the refrigerator door closed completely? Is the refrigerator opened frequently?

Vapor generated inside and outside the cabinet.

* The Vapor will generated outside the cabinet when the humidity is high (e.g. during rainy season) or the air circulation is not good.* If the vapor generated inside the cabinet, check that the door is completely closed or not. Is the refrigerator frequently opened or left opened for a long time? Is there is any hot foodstuff refrigerated in it?

The refrigerator generates noise.

* Check if the refrigerator is located on a stable floor or is installed properly.* Check if there is any object in contact with the refrigerator.
