Installation
Important!!! Please 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 air ow. 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, please let unit stand still for a minimum of 24
hours before plugging it in.
• Make sure that the unit drops down to desired temperature before loading the unit with product.
• 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.
• Please read through the manual in its entirety.
Cabinet Location Guidelines
• Install the unit on strong and leveled surfaces
- Unit may be noisy and/or malfunction if surface is uneven.
• Install the unit in an indoor, well-ventilated area
- For best performance, please maintain clearance of 4” on the back of the unit. Brackets should be attached on the
back of the unit.
- Outdoor use may cause decreased efficiency and damage to the unit.
• Avoid installation in a high humidity and/or dusty area
- Humidity could cause unit to rust and decrease efficiency of the unit.
- Dust collected on condenser coil will cause unit to malfunction.
- Malfunction due to dirty condenser will void warranty.
• Select a location away from heat and moisture-generating equipment
- High ambient temperatures will cause the compressor to overwork, leading to higher energy bills and gradual
breakdown of the unit.
- The unit should not be used in areas over 90 degrees.
- Malfunction due to high ambient temperature will void warranty.
• For optimal performance, 3” of clearance is required around all louvered or vented panels, to allow
for proper air ow
-For your convenience, a set of brackets is included to prevent this unit from being pushed up against a wall
-Component failure due to improper installation is not covered under warranty.

Electrical
• Please ensure that the required voltage of the compressor is being supplied at all times. Low or
high voltage can detrimentally affect the refrigeration unit.
• All units should be plugged into a grounded and properly-sized electrical outlet with appropriate
overcurrent protection. Please refer to the electrical requirements on the nameplate.
• Please make sure that your unit has its own dedicated outlet.
• Do not use an extension cord.
Temperature Controls
• Refrigerant LED - Compressor is on
• Fan LED - Fan is on
• Defrost LED - Defrost cycle is running
Functions
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 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 +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.

Loading Product
Before loading shelves, please 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 maintain correct air ow inside the unit, please be sure to leave two to four (2 to 4) inches
of space between the back wall and stored product. Blocking the evaporator fans will result in a
warmer cabinet temperature, and ultimately compressor failure.
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:
Freezers: Press the defrost button (“def” and down arrow) for approximately 5 seconds. Repeat to
stop the defrost cycle.
Refrigerators: Press the defrost button (snowake symbol and down arrow) for approximately 3
seconds. Repeat to stop the defrost cycle.
Defrost Systems
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. Freezer coils are defrosted electrically. Automatic defrost timers
automatically initiate at pre-set intervals and for a pre-determined duration.

Regular Maintenance
WARNING: DISCONNECT POWER CORD BEFORE
CLEANING ANY PARTS OF THE UNIT.
Cleaning The Condenser Coil
• For efcient operation, it is important that the condenser surface be kept free of dust, dirt, and lint.
• We recommend cleaning the condenser coil and ns at least once per month.
• Clean with a commercial condenser coil cleaner, available from any kitchen equipment retailer.
Brush the condenser ns from top to bottom, not side to side.
• After cleaning, straighten any bent condenser ns with a n comb.
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 stainless
steel surface.
• Wash door gaskets on a regular basis, preferably weekly. Simply remove door gasket from the
frame of the door, soak in warm water and soap for thirty (30) minutes, dry with soft cloth, and
replace.
• Check door gaskets 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, rst remove the shelves and shelf brackets. Then, simply lift
the pilaster up and out.
