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 220V with a frequency of 50Hz.
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.

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.

Chapter 3 Installation, adjustments and maintenance
3-1. Installation
The freezer should be conveniently located for day-to-day use in a dry well-ventilated room.
Do not install the freezer where the temperature will go below 0°F or above 110°F, because it will not maintain proper temperatures.
Be sure to install the freezer on a floor strong enough to support it when it is fully loaded.
The freezer must be solidly positioned on the floor if it is to function at its best. Shims may be used to accomplish this wherever the floor is too uneven. If the place selected for the freezer is damp or moist, place 2 X 4 s (51 mm X 102 mm) under its entire length to assure adequate support.
3-2 Defrosting and Draining
In most climates, defrosting will be necessary only about twice a year.
To have the freezer operate most efficiently, do not permit more than 1/2” (13 mm) of frost to accumulate on the shelves.
To remove frost, scrape with a plastic or wood spatula or scraper.
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 your freezer.
For Complete Defrosting
1. Turn the temperature control to the OFF position and unplug the freezer.
2. Remove all food and place it in corrugated boxes, insulated bags, picnic coolers, etc. Use towels and newspapers for insulation as needed.
3. With the door/lid open, use pans of hot water to speed loosening of frost. Remove large pieces before they melt.
Chest models have a defrost water drain at the front.
4. Sponge excess water from the bottom of the freezer as it collects to prevent over flowing.
5. After defrosting, clean the inside of the freezer.
6. Replace the drain plug inside the cabinet and the cap on the defrost drain. Fold over and dry the gasket on the hinge side of the lid.
7. Plug in the freezer. Return the temperature control to its previous position and return food to the

Water may drip from the back flange of the lid cover during defrosting. This is normal. Ice builds up in the lid insulation when the lid is open for adding or removing food, and melts during the defrosting operation.
3-3 Cleaning the Freezer
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 containing bleach.
Inside. Clean the inside of your 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.
Use warm water and baking soda solution-about a tablespoon of baking soda to a quart of water.
Rinse thoroughly with water and wipe dry. Do not use cleaning powders or other abrasive cleaners.
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.

Note: When assembly thermostat you should placed thermostat in originally direction.
Chapter 5 Control and display system
5-1. Control panel
Freezing temperature selection is made by setting the control from min to max (coldest).
If you want colder or warmer temperatures, adjust the control one step at a time.
Allow several hours after each one-step adjustment for the freezer temperature to stabilize.
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. The display screen presents the original setting temperature 0°F or -18℃ and blinks with
1HZ frequency; Then it displays actual inside temperature automatically after 5 seconds.
4. To press the downward button for 3 seconds under keyboard locking condition, temperature display starts to flash and the system is entering the setting status( when it comes into setting status every time, the figure of temperature blink is the one of setup last time ).
5. Allow freezer to operate for at least two hours before placing food inside.

1、 When frozen sensor failure or short circuit occur, the control panel displays" EE", and blinks in
1HZ frequency with buzzer sound together. At that time, system enter into safety mood, that is in the cycle working state of starting for 10 minutes and of stopping 5 minutes of compressor; then clicks the" alarm" button, it can relieve buzzer sounds, but" EE" is still using the 1HZ frequency flicker; when fault is excluded, regardless of to or not to press the" alarm button, buzzer sound relieves and normal temperature is displayed on control panel.
2、 If the actual temperature is T < - 31 degrees or T < - 35 degrees, control panel displays" LL" with 1HZ frequency flicker. At the same time control panel sounds continuous buzzer alarm. At this time to press the alarm button, alarm buzzer sound stops, but it still shows "
LL"; After fault excluded, normal temperature is displayed on control panel.
Note: - 30 to - 35 degrees C displays - 30C; it displays LL below – 35C
- 22 f to - 31 degrees F displays - 22 F, below - 31 degrees F displays LL
3、 When the actual temperature of T > 99 degree F ( T > 37 degrees C), the control panel displays" HH" with 1HZ frequency flicker; at the same time continuous buzzer alarm sounds from control panel; at this time to press the alarm button, alarm buzzer stops, but control panel still shows " HH"; After fault solved, normal temperature is displayed on control panel.
4、 To press super freezer button for 3 seconds, quick-frozen function starts; a buzzer alarm sounds from panel after 56 hours of continuous operation and without cancellation of this function; then system is into protection mode after 1 minutes sounds and forces the compressor to stop working for 5min’ At last quick-frozen opening function automatically canceled and the system returned to normal working state.
Note: under quick frozen case, its function is out of sensor control.
