IMPORTANT SAFETY NOTICE

WARNINGThe service information is designed for experienced repair technicians only and is not designed for use by the generalpublic. It does not contain warnings or cautions to advise non-technical individuals of potential dangers in attemptingto service a product. Products powered by electricity should be serviced or repaired only by experienced professionaltechnicians. Any attempt to service or repair the product or products dealt within this service information by anyoneelse could result in serious injury or death.

CFCs have been used in refrigerant as refrigerator and the insulation materials for many years. But itis now known that these compounds which once seemed so ideal for use as cleaning agents and inrefrigeration systems, destroy the earth’s ozone layer as a result, an international body decided on a total worldwide ban of harmful CFCs by the end of 1995.

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 transportation, 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

6.1 How to operate “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.

6.2 How to use the “ENERGY-SAVING” operationWhen 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 compressor ata lower speed than the normal operation.

6.3 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)

6.4 About energy saving• Deodorizing function reduces.• Interior temperature gets slightly higher.• Frequent opening of the doors raise the interior temperature. (Higher interior temperature automatically activates normal operation on a temporary basis).• When the “ENERGY SAVING” is activated during “QUICK FREEZING”, the “ENERGY SAVING” starts after completing the “QUICK FREEZING”.• The “ENERGY SAVING” operation stops when the power cord is reconnected or after recovering from a power failure.

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.

7. REFRIGERATOR INSTRUCTION GUIDELINES

1. Do not open the refrigerator frequently or leave it opened for a long time. This is to prevent water dipping inside the refrigerator which will cause the waste of coolness and consuming 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 overload 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 bottle bigger than the door shelf or the tray as the door will not close completely causing the coolness leakage.

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 consuming 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 refrigerator every three 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 “Sweating” on the outer surface of the cabinet without consuming the energy. This will make the outer wall of the refrigerator gets warm and is not a malfunction.

9. Drinking water bottles, beverage bottles such as soft drink and fruit juice should be seal closely to prevent odor gets into the bottles.

Before calling for servicing, please check as follows.The refrigerator does not operate.

* Check to be sure that the plug and its socket are in good conditions.* Check to see if 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 to see if the refrigerator is overloaded with stuff or 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

* There could the vapor outside the cabinet if the weather is humid as it is in rainy season or the air circulation is not good.* If there is vapor in the refrigerator, check to see 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 to see if the refrigerator is located on stable floor or is located evenly.* Check to see if there is any object contact with the refrigerator.
