This unit is intended for use in a temperature-controlled environment less than 75°F and 60%
relative humidity.
IMPORTANT – Read Before Installation:
• If the shelf has a raised lip, the lip needs to be installed facing up towards the rear of the cabinet to
promote proper airflow. Failure to install the shelves properly is considered user error and is not
covered by warranty.
• If the unit has recently been transported on its side, let the unit stand upright for a minimum of
24 hours before plugging it in.
• Make sure that 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 that there is proper ventilation around the unit in the area where it will operate.
• Make sure all accessories are installed (i.e., shelves, shelf clips, casters) before plugging the unit in.
• Do not attempt to remove or repair any component of the unit. Consult an authorized service
technician for servicing/repair.
• Do not sit inside the unit or hang on the doors.
• Read through the manual in its entirety.
• This unit should be located away from doors, air ducts, and fans that could disrupt airflow and negatively
impact performance.
Installation
• Install the unit on a strong and level 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.
- For best performance, maintain clearance of 3" on the back and the sides of the unit.
- Brackets should be attached on the back of the unit.
- Do not use outdoors. For indoor use only.
- Avoid direct sunlight.
• Avoid installation in a high humidity and/or dusty area.
- Humidity above 60% can cause the unit to rust, collect condensation, and may decrease eciency.
- Dust collected on the condenser coil will cause the unit to malfunction.
• Select a location away from heat and moisture-generating equipment.
- Ambient temperatures above 75°F may cause the compressor to malfunction.
- For optimal performance, this unit should not be used in environments with ambient temperatures
exceeding 75°F.
- The unit should not be placed in areas with an ambient temperature over 90°F.
- Equipment malfunctions due to ambient temperatures above 90 degrees could void the warranty.
- Do not install this unit inside a closet or alcove.

• 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 projection. Refer to the electrical requirements on the unit’s nameplate.
• The unit should have its own dedicated circuit.
• Do not use extention 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, 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.

Adjusting the Temperature
Your new refrigerator or freezer is already factory set to run at optimum temperature 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.
Freezers are set to cycle between a minimum temperature of -5°F and a maximum
temperature of 2°F.
Adjusting the temperature changes the minimum temperature your unit will run at. Your unit will not run con-
stantly 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.
• Press “SET” again to save your settings.
Always remember to calculate the dierential 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 o. Setting the temperature too high will result in unsafe maximum temperatures.

Loading Product
Before loading shelves, be sure that all shelf clips are completely fastened in their correct locations. It is
important that all shelves rest completely level before stocking your cabinet with product. In order to main-
tain correct airflow inside the unit, be sure to leave 2"-4" inches of space between the back wall and stored
product. Blocking the evaporator fans will result in a warmer cabinet temperature, and ultimately, compres-
sor failure.
Defrost System
Refrigerator coils are kept below the freezing point (32°F). During compressor downtime, 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-o water is drained into the evaporator pan and
evaporated. Freezer coils are defrosted electronically. Automatic defrost timers automatically initiate at pre-
set intervals and for a pre-determined duration.
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, press the defrost button (snowflake symbol and down arrow) for
approximately 3 seconds. Repeat to stop the defrost cycle.

Operation / Maintenance
Pay close attention to the safety notices in this section. Disregarding these notices may lead to
serious injury and/or damage to the unit.
ATTENTION
• To minimize shock and fire hazards, be sure not to overload outlet. Designate one outlet for
your unit.
• Do not use extension cords.
• Do not put your hands under the unit while it is being moved.
• When the unit is not in use for a long period of time, unplug the unit from the outlet.
• After unplugging the unit, wait at least 10 minutes before plugging it back in. Failure to do so could
cause damage to the compressor.
UNPLUG CORD
• To minimize shock and fire hazards, do not plug or unplug the cord with wet hands.
• Unplug the unit during maintenance and cleaning.
Safety / Warning
PROPER GROUNDING REQUIRED
• To minimize shock and fire hazards, make sure that the unit is properly grounded.
WARNING
• Do not attempt to remove or repair any component unless instructed by factory.
• Make sure that the unit is not resting on or against the electrical cord and plug.
• To minimize personal injury, do not hang on the doors.
• Do not store any flammable and explosive gas or liquids inside the unit.
• Do not attempt to alter or tamper with the electrical cord.
WARNING: DISCONNECT THE POWER CORD BEFORE CLEANING ANY PARTS OF THE UNIT.
NOTE: We strongly recommend that any servicing be performed by an authorized service technician.
Loading Product

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 the 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.
• Wash door gasket(s) on a regular basis, preferably weekly. Simply remove the door gasket(s) from the
frame of the door(s), soak in warm water and soap for thirty (30) minutes, dry it with a soft cloth, and
replace it.
• Check door gasket(s) for proper seal after they are replaced.
• Periodically remove the shelves and pilasters from the unit and clean them with mild soap and warm
water. To remove the pilasters, first, remove the shelves and shelf brackets. Then, simply lift the
pilaster up and out.
Cleaning the Condenser Coil
• For ecient operation, keep the condenser surface free of dust, dirt, and lint.
• We recommend cleaning the condenser coil at least once per month.
A dusty condenser may lead to high energy consumption, less cooling eectiveness, and
compressor damage.
Condenser Coil Cleaning Instructions:
The condenser coil is located at the bottom behind the panel.
1. Disconnect the electrical power from the unit.
2. Remove the front cover and base cover with a screwdriver.
3. Using a soft brush and/or vacuum, remove the dirt, lint, etc. from the finned condenser coil in a vertical
direction.
4. Clean the condenser with a commercial condenser coil cleaner, available from any kitchen equipment
retailer. Ex. Noble Chemical Tech Line.
5. After cleaning, straighten any bent condenser fins with a fin comb.
6. When finished, be sure to reinstall the front cover and base cover.
7. Reconnect the electrical power to the unit.
