WA R N I N G
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.
WA R N I N G
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 ad jus t t he tempera tur e c ont rol according to th e r equ ired 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 desired 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
TEMPERATURE DISPLAY:
The thermometer shows the warmest frozen food temperature. It is adjusted and designed so that only temperature
below 32°F (0°C) is accurately displayed.
THE FUNCTION OF THE CONTROL PANEL:
The numbers 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.
MXF25CHC-2 (Top Image) - When the red light is ON, the compressor is
working.
ALL OTHER MODELS (Bottom Image) - 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 ice cream and similar ready-frozen foods.
Product must not be filled higher than the stacking mark on the inside of the freezer. (4" from the sliding lid)

GENERAL MAINTENANCE AND CLEANING:
1. To save energy, keep the door closed as much as possible. Do not open the door frequently or leave it open for
extended periods of time. This will conserve energy and preserve the quality of the food in the cabinet.
2. Never place heavy or hot items on the top of the freezer to avoid damage to the appliance.
3. Turn OFF the power before cleaning.
4. To clean the freezer, use a soft cloth with mild detergent and hot water.
5. Use warm water to clean the magnetic gasket in order to maintain its elasticity. Apply some talcum powder to it to
prolong its service life. If the gasket is damaged, replace it immediately.
6. The freezer should not be left unused for a long time. To stop using the freezer and to store it, safely disconnect the
main power first, then clean the inside and leave the door open for 2-3 days with an open box of baking soda in the
cabinet. Make sure the inside of the cabinet is dry before storing.
7. To return the freezer to use, clean the inside cabinet with a sanitizing solution. Wipe thoroughly with a damp cloth.
Allow the unit to air dry, leaving the door open for 2-3 days.
CLEANING THE CONDENSER (Related Warranty Information)
•Condensers will accumulate dirt and require cleaning every 30 days.
•Dirty condensers result in compressor failure, product loss, and lost sales, which are not covered by warranty.
•If you keep the Condenser clean you will minimize your service expense and lower your electrical costs.
•The Condenser requires scheduled cleaning every thirty days or as needed.
•Air is pulled through the Condenser continuously, along with dust, lint, grease, etc.
•A dirty Condenser can result in voiding the unit's warranty coverage, as well as, compressor failure, product loss
and loss of product sales.
•Proper cleaning involves removing dust from the Condenser. By using a soft brush, or vacuuming the Condenser
with a shop vac, or using CO2, nitrogen, or pressurized air.
•If you cannot remove the dirt adequately, please call our technical service number and we will refer you to local
companies.
•On most of the units the condenser is accessible in the rear of the unit. You may need to remove the cabinet grill to
expose the refrigeration system and piping network.
•The Condenser looks like a group of vertical fins. You need to be able to see through the condenser for the unit to
function at maximum capacity. Do not place filter material in front of condensing coil. This material blocks
air-flow to the coil similar to having a dirty coil.
