Installation
Please read this manual thoroughly prior to equipment setup, operation, and maintenance.
This unit is intended for use in a temperature-controlled environment of less than 75°F and 55% relative
humidity. Malfunction due to improper conditions is not covered under warranty.
Before Installation
•
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. 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.
•
Please do not sit inside the unit.
•
Please read through the manual in its entirety.
•
The unit should be located away from doors, air ducts, and fans that could disrupt airflow and
negatively impact performance.
Cabinet Location Guidelines
•
Install the unit on strong and leveled surfaces.
• If the surface is uneven, the unit may be noisy.
• The unit may malfunction if the surface is uneven.
• Uneven floors may cause leakage or water on the floor.
•
Install the unit in an indoor, well-ventilated area.
• For best performance, please maintain clearance of 6” on the front and 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 55% can cause the unit to rust, collect condensation, and may decrease eciency.
• Dust collected on condenser coil will cause unit to malfunction.
• Malfunction due to temperatures above 75 degrees Fahrenheit, humidity above 55%, or improperly
maintained condenser coil will void the warranty.
•
Select a location away from heat and moisture-generating equipment.
• Ambient temperatures above 75 degrees Fahrenheit may cause the compressor to malfunction.
• Malfunction due to ambient temperatures above 75 degrees Fahrenheit will void warranty.
• Do not install the unit inside a closet or alcove.
Position the Merchandiser at its final location before removing the shipping skid. There are four bolts at the bottom
of the merchandiser that secure the shipping skid. Keep the unit lifted, and remove all four bolts to remove the skid.

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 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 at which your unit will run. Your unit will not run
constantly at this setting. To change it, follow these instructions:
Digital Control Units
1.
Hold "SET" for 1 second. The display will flash the
current minimum temperature.
2.
Use the arrow buttons to adjust the minimum
temperature you'd like the unit to run at.
3.
Press "SET" again to save your settings.
Refrigerator Control
•
Always remember to calculate the dierential if you change the minimum temperature setting.
The cabinet temperature will fluctuate up to 7°F 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.
Defrost System
Refrigerator coils are kept below the freezing point (32 degrees Fahrenheit). 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.
