User Manual
Installation
Please read this manual thoroughly prior to equipment set-up, operation, and maintenance.
This unit is intended for use in a temperature-controlled environment less than 75ºF and
55% relative humidity. Malfunction due to improper conditions is not covered under warranty.
Important!!! Please Read Before Installation
• If the unit has recently been transported on its side, please let the unit stand upright for a
minimum of 24 hours before plugging it in.
• Make sure the unit has reached the desired temperature before loading the unit with products.
This unit is meant for keeping cold products cold, not chilling warm products.
• Make sure all accessories are installed (shelves, shelf clips, etc.) before plugging in the unit.
• Do not attempt to remove or repair any component of the unit. Consult an authorized service
technician for servicing / repair.
• Do not stand inside the unit.
• Please read through this manual in its entirety.
• This refrigerator is designed to perform in a temperature-controlled environment less than 75°F
and 55% relative humidity. The unit should be located away from doors, air ducts, and fans that
could disrupt airow and negatively impact performance.
Cabinet Location Guides
• Install the unit on a strong and leveled surface.
- If the surface is uneven, the unit may be noisy.
- The unit may malfunction if the surface is uneven.
• Install the unit in an indoor, well-ventilated area away from doors, air ducts, and fans.
- For best performance, maintain 6” of clearance on the back of the unit at all times.
- Do not use outdoors. For indoor use only.
- Avoid direct sunlight.
• Avoid installation in a high-humidity and / or dusty area.
- High humidity can cause the unit to rust and may decrease efciency.
- Dust collected on the condenser coil may cause unit to malfunction.
- Malfunction due to high ambient temperatures, humidity, or improperly maintained
condenser coil will void the warranty.
• Select a location away from heat and moisture-generating equipment.
- High ambient temperatures may cause the compressor to malfunction.
- Malfunction due to high ambient temperatures and humidity will void the warranty.

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 re 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.
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°F and a maximum temperature
of 40°F.
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 ash 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 uctuate up to +4 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.

Refrigerator Control
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 (snowake 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 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. Freezer coils are defrosted
electrically. Automatic defrost timers automatically initiate at pre-set intervals and for a
pre-determined duration.
• If a drainage pipe is available, lower the condensation drainage pipe and connect to a drain or
condensate pump. Verify the pipe is unobstructed and it is lower than the water receiver indicated
by the line on the sticker.
• If no drain is available, the condensation drainage pipe can be hung up. The excess water will be
evaporated with the condensate evaporator pan. Note that the use of this option will increase the
energy consumption of the unit.
• WARNING: High humidity environments can cause increased amounts of condensation that can
overow the evaporator pan. Connecting the drainage pipe to a nearby drain is necessary for
environments exceeding 55% relative humidity.

Operation/Maintenance
NOTE: We strongly recommend that any servicing be performed by an authorized service technician.
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. Do not block return air ow in the front of the unit.
• Ensure all shelves are sitting level and properly secured before loading products.
• Do not store ammable and explosive gas or liquids inside the unit.
Cleaning the Condensor Coil
• For efcient 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.
