Electrical
• Please ensure that the required voltage is being supplied at all times.
• The unit should be plugged into a grounded and properly-sized electrical outlet with appropriate
over-current protection. NEVER USE AN ADAPTER PLUG! Please refer to the electrical
requirements on the unit’s nameplate.
• This unit should have it’s own dedicated outlet.
• Do not use extension cords.
• Do not unplug your cooler by pulling on the power cord. Grip the plug firmly and pull straight out
from the outlet.
• Ensure the unit is not resting on or against the electrical cord.
• If the unit is not in use for a long period of time, please unplug the unit from the outlet.
• To avoid shock and fire hazards, do not plug in or unplug the unit with wet hands.
• After unplugging the unit, wait at least 10 minutes before plugging it back in. Failure to do so
could cause damage to the compressor.
• If the power cuts off, wait at least 5 minutes before turning the unit on to avoid damage to
the compressor.
Adjusting the Temperature
Your new refrigerator or freezer is already factory-set to
run at optimum temperatures for food safety and should
require no adjustments.
Refrigerators are set to cycle between a minimum temperature of 33 degrees Fahrenheit and a
maximum temperature of 40 degrees Fahrenheit.
Freezers are set to cycle between a minimum temperature of -5 degrees Fahrenheit and a
maximum temperature of 2 degrees Fahrenheit.
Adjusting the temperature changes the minimum temperature your unit will run at. Your unit will
not run constantly at this setting. To change it, follow these instructions:
Digital Control Units
• Hold “SET” for 1 sec. The display will flash the current minimum temperature.
• Use the arrow buttons to adjust the minimum temperature you want it to run at.
• Press “SET” again to save your settings

User Manual
Always remember to calculate the differential if you change the minimum temperature setting. The
cabinet temperature will fluctuate up to +7 degrees over your set minimum temperature as the
compressor runs and shuts off. Setting the temperature too high will result in unsafe maximum
temperatures and possible health code violations.
Running a Manual Defrost Cycle
This unit is pre-programmed to run automatic defrost cycles at preset intervals. However, if you
would like to run a manual defrost cycle at any time, please follow the steps below:
Refrigerators: Press the defrost button (snowflake symbol and down arrow) for approximately
3 seconds. Repeat to stop the defrost cycle.
Defrost System
Refrigerator coils are kept below the freezing point (32°F). During compressor down-time, the
evaporator fan continues to circulate air through the evaporator coil. This air circulation raises the
coil temperature above the freezing point, melting any accumulated frost. Run-off water is drained
into the evaporator pan and evaporated.
Operation/Maintenance
NOTE: We strongly recommend that any servicing be performed by an authorized service technician.
Unplug the unit from the electrical outlet before cleaning or making repairs.
Loading Product
• Do not block the air duct/fan at the top of the unit. Maintain a minimum of 4” of clearance between
products and the fan at all times.
• Ensure all shelves are sitting level and properly secured before loading products.
• Do not store flammable and explosive gas or liquids inside the unit.
Cleaning the Condenser Coil
• For efficient operation, keep the condenser surface free of dust, dirt, and lint.
• We recommend cleaning the condenser coil at least once per month.
• Clean the condenser with a commercial condenser coil cleaner and a soft brush, available from
any kitchen equipment retailer, or vacuuming the condenser with a shop vac or use CO2.
Cleaning the Fan Blades and Motor
• If necessary, clean the fan blades and motor with a soft cloth.
• If it is necessary to wash the fan blades, cover the fan motor to prevent moisture damage.
