Chapter 1 General Information

1-1. General Guidelines

When servicing, observe the original lead dress. If a short circuit is found, replace all parts which

have been overheated or damaged by the short circuit. After servicing, see to it that all the protective

devices such as insulation barriers, insulation papers shields are properly installed. After servicing,

make the following leakage current checks to prevent the customer from being exposed to shock

hazards.

1) Leakage Current Cold Check

2) Leakage Current Hot Check

3) Prevention of Electro Static Discharge (ESD) to Electrostatic Sensitive

1-2. Important notice

1-2-1. Follow the regulations and warnings

Most important thing is to list up the potential hazard or risk for the service personnel to open the

units and disassemble the units. For example, we need to describe properly how to avoid the

possibility to get electrical shock from the live power supply or charged electrical parts (even the

power is off).

This symbol indicates that high voltage is present inside. It is dangerous to make any

king of contact with any inside part of this product.

This symbol indicates that there are important operating and maintenance instructions in

the literature accompanying the appliance.

1-2-2. Be careful to the electrical shock

To prevent damage which might result in electric shock or fire, do not expose this component to rain

or excessive moisture. This component must not be exposed to dripping or splashing water, and

objects filled with liquid, such as vases, must not be place on top of or above the component

1-2-3. Electro static discharge (ESD)

Some semiconductor (solid state) devices can be damaged easily by static electricity. Such

components commonly are called Electrostatically Sensitive (ES) Devices. The following techniques

should be used to help reduce the incidence of component damage caused by electro static

discharge (ESD).

1-2-4. About lead free solder (PbF)

This product is manufactured using lead-free solder as a part of a movement within the consumer

products industry at large to be environmentally responsible. Lead-free solder must be used in the

servicing and repair of this product.

1-2-5. Use the genewing parts (specified parts)

Special parts which have purposes of fire retardant (resistors), high-quality sound (capacitors), low

noise (resistors), etc. are used.When replacing any of components, be sure to use only

manufacture's specified parts shown in the parts list.

Safety Component

● Components identified by mark have special characteristics important for safety.

1-2-6. Safety Check after Repairmen

Confirm that the screws, parts and wiring which were removed in ordertoservice are put in the original

positions, or whether there are the portions which are deteriorated around the serviced places

serviced or not. Check the insulation between the antenna terminal or external metal and the AC cord

plug blades. And be sure the safety of that.

Insuration Test

1. Check if there is any leak of current.

2. Cut out the power supply before the repair to avoid an electrical shock hazard.

3. In the case of a live-line test, insulating gloves should be worn to avoid potential electrical

shock.

4. Confirm the rated current, voltage and capacity before testing with any kinds of instruments.

5. Watch if the upper door is open when you check something at a lower position.

6. Take out every part in the cabinet before moving the machine, especially things like panels

(e.g. glass shelf).

7. Please wear intact cotton gloves when repair any parts of the evaporator, so that scratches

by the sharp fins can be avoided.

8.

If there is a breakdown with the refrigeration system, please surrender the machine to

the service center, else the leaked refrigerant may pollute the atmosphere

.

9. The refrigerator use AC of 220~240V with a frequency of 50Hz.

10. A big fluctuation of voltage (exceed the range 220～240V) may cause a start failure of the

refrigerator, a burn-out of the control panel and compressor, or an abnormal sound from the

compressor in operation. In this condition an automatic voltage regulator over 750W should be added.

11. Take care not to damage the supply line. Don’t yank at the line; pull the plug out gently from

the receptacle. Don’t press the line under the cabinet or step on it. Take care not to roll on or damage

the supply line when moves the machine from the wall.

12. In the case of leakage of inflammable gases like carbon monoxide, open the door and

windows. Don’t pull out or insert the plugs of the appliance.

13. Don’t touch the refrigeration surface of the freezing compartment when the refrigerator is in

operation, especially when your hand is wet, else you may be glued to the surface.

14. Pull out the plug of power supply during clearance or power outage. Wait at least five

minutes to resume the power supply in order to prevent damage to the compressor caused by

continuous restart.

2-3. Major features

2-3-1.Features

1. New appearance of three stainless steel doors, fashionable and luxurious, satisfies the

demands of the modern high-income families. Fully closed freezing system and drawer storage

can avoid food tainting, keep cold and are energy-saving. As warm air can't easily enter into the

storage area when opening the door.

2. Fully frequency control: it integrates the techniques of frequency conversion, de-noise,

energy-saving and quick-freezing which can benefit mutually to make better performance. The

refrigerator can automatically adjust the working efficiency of the frequency conversion

compressor by comparing the inside temperature with the setting temperature and keeps the

refrigerator in the optimized status all the time.

3. Two functions are added to the Chiller chamber: defrost（D-Frost）、quick cool（Q-Cool）, when

defrost function works, the temperature of the Chiller chamber will reach to +1℃; When quick cool

function works, the temperature of the Chiller chamber is -1℃。

4. Cool wind but no frost: adopting fully air cooled refrigeration system, deep cooling and quick

freezing.

5. Quick cool function: the refrigerating chamber can be adjusted to quick cool status, after

being at this status, it will automatically turn on the function of quick cool and make the food go

through the max ice crystal zone and thus effectively reserve the nutrition.

6. Holiday function: when you are out for holiday, refrigerator will run at the low energy

consumption to make sure there's no odor in the refrigerating chamber and guarantee soft

freezing and the normal storage of frozen food.

7. LED display: adopting dynamic LED to display the operational situation of refrigerator.

8. Sliding shelf, folding bottlerack: there are designs of sliding shelf and folding bottlerack for the

refrigerating chamber to make storing and taking articles easier.

9. LED light guide plate illumination: adopting the technique of light guide plate illumination, the

light is soft, even, bright and no illumination dead angle.

10. Double-drawer freezing door body: the freezing chamber adopts the double-drawer door

body which can be opened straightly and completely. It makes storing and taking food easier. The

imported slide rail with automatic door closing device can save labor as well as electric power.
