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. Please refer to the electrical requirements on the unit’s nameplate.
• The unit should have its own dedicated outlet.
• Do not use extension cords.
• 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.
Temperature Controls
Adjusting the Temperature
Your new refrigerated deli case 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
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.

User Manual
Running a Manual Defrost Cycle
Units are 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. Only models with digital controls can
run a manual defrost cycle. Units with mechanical controls cannot run a manual defrost cycle.
Freezers: Press the defrost button (“def” and down arrow) for approximately 5 seconds. Repeat to stop the
defrost cycle.
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 degrees Fahrenheit). During compressor down-
time, the evaporator coil warms up and raises the coil temperature above the freezing point, melting any
accumulated frost.
Run-off water is drained into the evaporator pan and evaporated. Freezer coils are defrosted electrically.
Automatic defrost timers automatically initiate at pre-set intervals and for a pre-determined duration.
Operation/Maintenance
NOTE: We strongly recommend that any servicing be performed by an authorized service technician.
Loading Product
• Do not block the coil.
• 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, available from any kitchen equipment
retailer.
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.
Cleaning the Interior of Unit
• When cleaning the cabinet interior, use a solvent of warm water and mild soap.
• Do not use steel wool, caustic soap, abrasive cleaners, or bleach that may damage the interior finish.
• Periodically remove the shelves and shelf brackets from the unit, and clean them with a mild soap
and warm water.
