SERVICE MANUAL
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 useAC of 115V with a frequency of 60Hz.
10. A big fluctuation of voltage (exceed the range 187～242V) 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

3

SERVICE MANUAL
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.

Chapter 3 Installation, adjustments and maintenance
3-1. Unpacking
1. Remove all packaging material; this includes the foam base and all adhesive tape holding the freezer
accessories inside and outside.
2. Inspect and remove any remains of packing, tape or printed materials before powering on the freezer.
3-2. Adjusting
1. The freezer is designed for freestanding installation only. It should not be recessed or built-in.
2. Place the freezer on a floor strong enough to support it fully loaded.
3. When moving freezer, never tilt it more than a 45-degree angle. This could damage the compressor
and the sealed system.
4. If freezer is tilted let it stand in an upright position for at least 24 hours prior to plugging. This is to allow
the refrigerant to settle.
5.Proper Air Circulation
To assure the freezer 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.
The following are recommended clearances around the freezer:
Sides…………..2”(50mm)

7
7
SERVICE MANUAL
Top. ……………2”(50mm)
Back…………..2”(50mm)
Do not over fill freezer for proper internal air circulation.
3-3.Electrical Requirement
Make sure there is a suitable power Outlet with proper grounding to power the freezer.
Avoid the use of cutting off the third grounding, this is a dangerous practice since it provides no effective
grounding for the freezer and may result in shock hazard.
3-4.Defrost
Defrosting and Draining the Freezer
1. Defrost whenever the frost becomes 5MM thick. Never use a sharp or metallic instrument to remove
the frost as it may damage the cooling coils.(Apunctured coil will void the warranty)
2. Unplug the unit. For draining, place a tray beneath the outer drain plug. Pull out the drain dial and
rotate it so that the arrow points down ward. This will let the water flow out into the tray.
3. Remove the drain plug from the inside of the freezer. Defrosting usually takes a few hours. To defrost
faster keep the freezer door open. When done, push the drain dial in and turn the arrow to the up
position. Re-plug the drain plug inside the freezer compartment. Note: monitor the container under the
drain to avoid overflow.
·Rest the temperature control to the desired setting.
3-5. Cleaning
Outside. Protect the paint finish. The finish on the outside of the freezer is a high quality baked-on
paint finish. With proper care, it will stay new-looking and rust-free for years. Apply a coat of appliance
polish wax when the freezer is new and then at least twice a year. Appliance polish wax also works well
to remove tape residue from freezer surfaces.
Keep the finish clean. Wipe with a clean cloth lightly dampened with appliance polish wax or mild
liquid dishwashing detergent. Dry and polish with a clean, soft cloth. Do not wipe the freezer with a soiled
dishwashing cloth or wet towel. Do not use scouring pads, powdered cleaners, bleach, or cleaners

SERVICE MANUAL
containing bleach.
Inside. Clean the inside of the freezer at least once a year. We recommend that the freezer be
unplugged before cleaning. If this is not practical, wring excess moisture out of sponge or cloth when
cleaning in the vicinity of switches, lights or controls.
An open box of baking soda in the freezer will absorb stale freezer odors. Change the box ever y
three months.
Care should be taken in moving the freezer away from the wall. All types of floor coverings can
be damaged particularly cushioned coverings and those with embossed surfaces.
Chapter 4 Disassembly
4-1. Door assembly (Door, hinge, hinge cover)
1. Unscrew the hinge cover screw with screwdriver, take away the top and bottom cover by pull it,
and then unscrew the screws on the hinge, so the whole hinge could be moved.
4-2. Compartment Grill assembly
Unscrew the two screw of grill, we can take away the grill.

Stretch your arm into the compartment, push the connector inside, when the clip falls off the
cabinet, and take off the control panel and the connective wire cord with an acutilingual plier.
4-4. Thermostat assembly
First take off the knob, Use turnbuckle spanner or acutilingual plier, unscrew the turnbuckle, then
thermostat can be moved from back of panel.
Note: When assembly thermostat you should placed thermostat in originally direction.

Freezing temperature selection is made by setting the control from 1to 7(coldest).
If we want colder or warmer temperatures, adjust the control one step at a time.

SERVICE MANUAL
Allow several hours after each one-step adjustment for the freezer temperature to stabilize.
Turning the control to the OFF position stops the cooling process but does not shut off power to
the freezer.
5-2. Starting the Freezer
1. Clean the inside of the freezer with a mild solution of baking soda and water
2. Connect cord to power outlet.
3. On models with a Temperature Monitor or High-Temp Alarm Switch, set the switch to the OFF
position.
4. Make sure the temperature control is set at 4.
5. Allow freezer to operate for at least four hours before placing food inside.
6. On models with a Temperature Monitor or High-Temp Alarm Switch, set the switch to the ON
position.
