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 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 115V with a frequency of 60Hz.

10. A big fluctuation of voltage 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.

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.

3-1-1.Unpacking the Unit:

Remove all packaging material. This includes the foam base and all adhesive tape holding the

Unit accessories inside and outside, compressor from shipping damage due to vibration and

shock.

Inspect and remove any remains of packing, tape or printed materials before powering on the

Unit.

3-1-2.Leveling the Unit:

The Unit has four leveling legs which are located in the front and rear corners of the Unit. After

properly placing the Unit in its final position, you can level the Unit.

Leveling cellar or by turning them clockwise to lower the unit, the unit door will close easier when

the leveling legs are extended.

Proper Air Circulation

1. To assure the unit works at the maximum efficiency it was designed for, you should install it in

a location where there is proper air circulation, plumbing and electrical connections.

2. The following are recommended clearances around the unit:

Sides…………..2” (50mm)

Top ……….……2” (50mm)

Back…………..2” (50mm)

3. Do not over fill the unit for proper internal air circulation.

3-1-3.Electrical Requirement

Make sure there is a suitable power outlet (115~V) with proper grounding to power the unit.

Avoid the use of three plug adapters or cutting off the third grounding in order to accommodate a

two plug outlet, this is a dangerous practice since it provides no effective grounding for the unit

and may result in shock hazard.

3-1-4.Install Limitations

Do not install the unit in any location not properly insulated or heated e.g. garage etc, the unit was

not designed to operate in temperature settings below 55 eFahrenheit.

Select a suitable location for the unit on a hard even surface away from direct sunlight or heat

source e.g. radiators, baseboard heaters, cooking appliances etc, any floor unevenness should

be corrected with the leveling legs located on the front and rear bottom corners of the unit.

The unit is designed for free-standing installation only; it is not designed for built-in application.

Explanation: The electromagnetism valve includes two single valves. When the two

compartment temperature does not reach the set temperature, the two valves are keeping open;

when one compartment temperature reaches the set temperature, the related valve is closed and

the other one is keeping open. Both the two compartments temperature reaches each set
