IMPORTANT SAFETY NOTICE
WARNING
The service information is designed for experienced repair technicians only and is not designed for use by the general
public. It does not contain warnings or cautions to advise non-technical individuals of potential dangers in attempting
to service a product. Products powered by electricity should be serviced or repaired only by experienced professional
technicians. Any attempt to service or repair the product or products dealt within this service information by anyone
else could result in serious injury or death.
CFCs have been used in refrigerant as refrigerator and the insulation materials for many years. But it
is now known that these compounds which once seemed so ideal for use as cleaning agents and in
refrigeration 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.

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 frequency
is low), the “ENERGY-SAVING” operation saves electricity consumption by operating the compressor
at 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.
