WARNING
HOW TO CONNECT ELECTRICITY
DO NOT, UNDER ANY CIRCUMSTANCES, CUT OR REMOVE THE GROUND PRONG FROM THE
POWER CORD. FOR PERSONAL SAFETY, THIS APPLIANCE MUST BE PROPERLY GROUNDED.
•The power cord from this appliance is equipped with a grounding plug which minimizes the possibility of electric
shock hazard.
•Have the wall outlet and circuit checked by a qualified electrician to make sure the outlet is properly grounded.
•It is your personal responsibility and obligation to have your outlet replaced with the properly grounded wall
outlet.
•The refrigerator should always be plugged into its own individual dedicated electrical circuit, which has a voltage
rating that matches the rating plate. This provides the best performance and also prevents overloading building
wiring circuits which could cause a fire hazard from overheated wires or tripping a circuit breaker / blowing a
protective fuse.
•Never unplug the equipment by pulling on the power cord. Always grip plug firmly and pull straight out from the
outlet.
•Repair or replace immediately all power cords that have become frayed or otherwise damaged.
•Do not use a cord that shows cracks or abrasion damage along its length or at either end.
•When removing the equipment away from the wall, be careful not to roll over or damage the power cord. If
power cord is damaged it should be replaced with original equipment manufacturer parts. To avoid hazard this
should be done by a qualified service technician.
•Do not plug the power cord into an extension cord. This can create a fire hazard or short circuit.
WARNING
Compressor warranties are void if compressor burns out due to low voltage.
Power supply cord ground should not be removed!
Do not use electrical appliances inside the compartments of this equipment.
TRANSPORTATION and INSTALLATION
1. When you transport the freezer, the angle between the compartment body and the
ground should be no more than 45°, and you should never place the freezer up-side down.
2. Do not use any of the external part as loading points, for example, the condenser on
the back, the door or the hinge.
3. When the freezer is installed or used, all the package (including board and foam
plastic) should be properly disposed of. Please recycle, when possible.
4. Keep the freezer stable and level to avoid vibration and noise.
5. The freezer should be installed in a place with good ventilation, a space of at least 4" (10cm) should be allowed
between the surrounding walls and the cabinet wall for proper air circulation.
6. It should be placed far from any heat source and not under direct sunshine to avoid less efficient performance due
to the high ambient temperature.
7. Install the freezer in a dry place to prevent the compartment body from rusting, which may (1) affect the electric
insulation (2) create a food safety contamination risk and (3) reduce the appliance's expected useful life.
CAUTIONS:
1. The freezer must be properly grounded to avoid a shock hazard.
2. In case of any damage to the electric wires and/or plug, please contact an authorized electrician to repair the
connection.
3. If the voltage is unstable, please provide a suitable automatic voltage regulator and/or surge protection.
4. Allow the freezer to reach its operating temperature before it is loaded with product.
5. You should adjust the temperature control according to the required temperature and quantity/tiers of the stored

4
food (ice cream tubs, etc.) and the environmental temperature/required conditions for the stored product to
maintain its quality.
6. Before putting product into the freezer please adjust the temperature control to its lowest set point and let it run
until the temperature of inner cabinet decreases to 0°F (-18°C.) Once the unit reaches 0°F (-18°C), set the unit to
your devised set point and load product. NOTE: For high elevation installations, it may be necessary to “warm-
up” the cabinet to higher set points.
7. Unplug the appliance by pulling the cord cap (plug) NOT the electrical cord.
8. Never put hot food in the freezer. Only place product in the freezer after it is has reached its ideal storage
temperature. Some foods will need to be placed in a refrigerator or another freezer to cool down past room
temperature prior to placing in the freezer.
9. Do not overfill the unit. Keep the top item at least 4" (10cm) below the brim on the cover. There should be
reasonable space between the food items for better temperature regulation.
10. If a power outage occurs, you should wait at least 5 minutes before the freezer is turned on again to avoid damage
to the compressor.
11. Never store any flammable, explosive and corrosive liquid or gas in the freezer. Keep it away from this appliance.
12. Beer, beverage, fresh flowers, medicine and injections cannot be put into the freezer for storage or cooling.
Handling them in the freezer voids the warranty
13. If the stored items are not place in properly sealed, protective packaging, then ice crystals may form or the
product quality can be affected.
NOTE! Before loading product we recommend you run the unit empty for two to three days. This allows you to be
sure electrical wiring and installation are correct and no shipping damage has occurred.
LOSS of FOOD PRODUCT IS NOT COVERED BY THE WARRANTY!

THE FUNCTION of the CONTROL PANEL:
The figure on the temperature control 1~7 reflect the relative temperature setting from high to low.
The specific temperature is not shown or indicated by this knob.
Turn the knob clockwise: the cabinet temperature will go DOWN.
Turn the knob counter-clockwise, the cabinet temperature will go UP.
The green light is a power indicator.
When the green light is ON, the power is connected.
After the temperature setting is adjusted and the appliance is turned on, it will take
time, possibly several hours for the unit to reach the new temperature setting.
DEFROST / IF ICE BUILDS UP ON INTERIOR WALLS:
1. Defrost the unit when the frost thickness on the wall of the cabinet reaches 1/4" (6mm) to optimize the freezing
capacity.
2. Turn the temperature control to the lowest point for 5-6 hours before defrosting.
3. Cut off the power and take out the food.
4. Use of warm water or a plastic scraper may accelerate the defrosting time of the cabinet wall.
5. After defrosting, clean the wall with dry cloth. Turn the power on.Allow time for the cabinet to reach its set-point
temperature. And then load the cabinet with food.
NORMAL OCCURENCES:
1. There may be a sound of flowing water when the refrigerant is running.
2. When the ambient humidity is too high, there will be condensation on the surface of the freezer and the lid.
3. When the machine is running, the condenser and compressor will be hot.
NOTE: Do not expect optimal performance if the ambient temperature exceeds 84°F (29°C) or the local
environment exceeds 60% relative humidity.
FOOD STORAGE:
The appliance is suitable for storing packaged ice cream and similar ready-frozen dessert items.
Product must not be filled higher than the stacking mark on the inside of the freezer. (4" from the sliding lid)

ICE CREAM HANDLING INSTRUCTIONS for DIPPING CABINET
Novelty Products:
•These items come pre-packaged. Simply place them in the storage baskets and segregate them by product type.
•Do not overfill the baskets or this product can soften or even melt.
•If you want to offer more variety, dividers and divided baskets can be used. It is recommended that novelties
be held between 5° and 10°F (-15° and -12°C). The product will remain firm but should be ideal for human
consumption.
Scoopable Frozen Dessert Offerings like Sherbet, Frozen Yogurt and Ice Cream:
•Product should be scooped with commercial duty scoops, spades or dishers such as
the Zeroll(R) product line. These professional dishers and scoops make defined product
balls without removing over-run or otherwise harming texture.
•If the items are made at the serving location, they should be produced in flanged
plastic or stainless steel containers. The containers can then be dropped easily into a
solid template designed for accessible dishing and serving.
•If the items are produced remotely, the shipping container is usually made of thin
cardboard or plastic can be inserted into the cabinet with an accessible template
opening for each offering. The solid skirt around the containers helps keep the cabinet
clean and attractive.
Health codes, inspectors & regulations require using a dipper well to store the scoops
throughout the day.
A semi-continuous flow of potable tap water is needed to keep the scoops clean removing butter-fat & trace product
smear that may stick to the scoop, restrict bacteria growth & stop flavor migration into another selection.
A flow rate ≤ ⅓ gpm is suggested with a water flow restrictor & a shut off valve to stop the flow in off-peak periods.
