Installation
Please read this manual thoroughly prior to equipment setup, operation, and maintenance.
This unit is intended for use in a temperature-controlled environment less than 75°F and 60% relative
humidity. Malfunction due to improper conditions is not covered under warranty.
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 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, please let 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.
• 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 hang on doors or stand inside the unit.
• Please read through the manual in its entirety.
• This unit is designed to perform in a temperature-controlled environment at 60% relative humidity.
The unit should be located away from doors, air ducts, and fans that could disrupt airflow and
negatively impact performance.
ON ALL DOORS:
• Remove the bracket from the bottom of the doors (Figure 1).
If this bracket is not removed, it can scratch the paint from
the top of the front grill.
Cabinet Location Guidelines
• 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.
- For best performance, please maintain clearance of 6” on the back 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 eciency.
- 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.
- Malfunctions due to ambient temperatures above 75°F will void the warranty.
- Do not install the unit inside a closet or alcove.
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 refrigerator is already factory set to run at optimum temperatures for white wine and food
safety, and would only require an adjustment for changes in wine type.
Refrigerators are set to cycle between a minimum temperature of 33 degrees Fahrenheit and a maximum
temperature of 70 degrees Fahrenheit.
Adjusting the temperature changes the minimum temperature
your unit will run at. Your unit will not run constantly in this setting.
To change it, follow these instructions:
DIGITAL CONTROL UNIT FIGURE 2
• 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 dierential 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 and possible
health code violations.

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.
Controller 1 (Figure 2): 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 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. Automatic defrost timers automatically initiate at pre-set intervals and
for a pre-determined duration.

Operation / Maintenance
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
• Do not block the air duct/fan at the top of the unit.
• 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 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.
• 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 a 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 ecient 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 eectiveness, and compressor damage.
CONDENSER COIL CLEANING INSTRUCTIONS
NOTE: 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 (example: Nobel 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.
