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. Insurance 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 we 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 220V 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.

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.

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 our hand is wet, else we 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.

Chapter 3 Installation, adjustments and maintenance

3-1. Installation

1 Do not install the wine cellar in any location not properly insulated or heated e.g. garage etc, the

wine cellar was not designed to operate in temperature settings below 6

2 Select a suitable location for the wine cellar on a hard even surfaces away from direct sunlight or

heat source e.g. radiators, baseboard heaters, cooking appliances etc, Any floor unevenness

should be corrected.

3 To assure the Wine cellar works at the maximum efficiency it was designed for, we should install it

in a location where there is proper air circulation, the following are recommended clearances

around the Wine cellar:

Sides…………..0.8” (20mm)

Top. ……………6.3” (630mm)

Back………….. 4” (100mm)

3-2 Adjustment

3-2-1.Operating the Wine cellar

1 Once the wine cellar is in its proper place, plug it in an electrical outlet having 100~110 volts.

2 Set the temperature, the temperature is adjustable from 6 to 18 . After using the wine cellar for

5 hours set the wine cellar to desired setting.

3-2-2. Wine Storage shelves

1 The Freezer has 5 removable even shelves and 1 removable cater-corner shelf. It allows storing

wine more accessibly or can be removed if not needed.

3-3Maintenance

3-3-1. Defrosting and cleaning the Wine cellar

1 Defrost whenever the frost becomes 1/4” thick. Never use a sharp or metallic instrument to

remove the frost as it may damage the cooling coils. (A punctured coil will void the warranty)

2 Unplug the power pin, then take out stored wine and place in a safety place. Defrosting usually

takes a few hours. To defrost faster keep the freezer door open.

3 When frost buildup has melted, wipe water off with a dry cloth. Replace the electrical plug in the

electrical outlet.

4 Reset the temperature control to the desired setting.

Do not use an ice pick or sharp-edged instrument as it may damage or scratch the freezer.

Do not use any electrical device in defrosting the freezer.
