Installation
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 flow. 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. 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 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 hang on doors or stand inside the unit.
• Please read through the manual in its entirety.
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.
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.
• 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 55% can cause the unit to rust, collect condensation, and may decrease eciency.
• 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.

Adjusting the Temperature
Electrical
Temperature Controls
• 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. 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, unplug 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.
• 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:
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.
Digital Control Units
Always remember to calculate the dierential 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
Operation
• 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.
• Automatic defrost timers 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 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.
• If your cooler utilizes wicking pads for absorption of condensation, it is recommended that the pads
(22477146) be replaced every 4-6 months depending on the ambient temperature and relative humidity of the
environment.
• If water is leaking from the cabinet, check that the wicking pads have recently been changed and/or the
drainage pipe is connected properly.
• WARNING: High humidity environments can cause increased amounts of condensation that can overflow the
evaporator pan. Connecting the drainage pipe to a nearby drain is necessary for environments exceeding 55%
relative humidity.
Automatic 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, 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: Press the defrost button ("DEF" and ▼) for approximately 5 seconds.
Repeat to stop the defrost cycle.
• Controller #2: Press the defrost button (Snowflake and ▼) for approximately 3 seconds.
Repeat to stop the defrost cycle.
Running a Manual Defrost Cycle
Loading Product
• Ensure there is at least 4" of clearance from the evaporator.
• Ensure all shelves are sitting level and properly secured before loading products.
• DO NOT store flammable/explosive gas or liquids inside the unit.

Adjusting the Temperature of the Top Bakery Case Section
Operation
• Four perforated baes come installed on
the unit for the unit to operate with a fully
refrigerated top section.
• Four solid baes are included for altering the
temperature of the top bakery case section.
• The bae will prevent (solid) or allow
(perforated) refrigerated air from circulating
through the display area and returning through
the air return grille.
• The top bakery case section of the equipment
can be ambient, refrigerated, or 50/50 ambient
and refrigerated:
1. For 100% ambient (non-refrigerated) conditions, two
solid baes must be positioned in each section of
the cabinet to block the air flow and the air return
grille.
2. For 100% refrigerated conditions, two perforated
baes must be positioned in each section of the
cabinet to allow air to circulate through the display
area and return through the air return grille.
3. For 50/50 ambient and refrigerated, position two
solid baes in the half of the case intended to be
ambient to block airflow. For the half intended to be
refrigerated, position two perforated baes to allow
air to enter and return through the air return grille.

Cleaning the Condenser Coil
Cleaning the Condenser Coil Instructions
• A dusty condenser may lead to high energy consumption, less cooling eectiveness, and compressor damage.
• 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.
• 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 Coil Cleaners (148TLECCCLNR, 148TLHDCCLNR, 148TLECOILDD,
148TLFMCCLNR, 147TLEVPCLNR, or 147TLHDCCLNR).
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.
