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 degrees
Fahrenheit 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 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 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.
Field Convertible Doors
The Avantco 178SS1RHC and 178SS1FHC both ship with a right-hinged door design. If
you would like to convert the reach-in to a left hinged door design (solid door models), you
must purchase the left hinges seperately (Avantco item #178SS1KITFR ) and follow these
instructions:
Tools Needed:
• Socket Set
• Pliers
• Adjustable Wrench
• Phillips Head Screwdriver

properly.
9. Put the door on the bottom hinge on the left side. You will need to reuse the brass spacer from
step 5.
10. Next, place the top bracket on the top of the door before bolting it to the unit with the 3 bolts.

• 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.
• Malfunctions due to temperatures above 75 degrees Fahrenheit, humidity above 60%, 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.

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 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 at which your unit will run. Your
unit will not run constantly at this setting. To change it, follow these instructions:
Freezer Control
Prg
mute
Set
aux
def
Refrigerator Control
set
mute
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.
Always remember to calculate the differential if you change the minimum temperature setting.
The cabinet temperature will fluctuate up to 7 degrees Fahrenheit over your set minimum
temperature as the compressor runs and shuts off. Setting the temperature too high will result
in unsafe maximum temperatures and possible health code violations.

Defrost System
Automatic Defrost Cycle
• 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.
• Freezer coils are defrosted electronically.
• Automatic defrost timers initiate at pre-set intervals and for a predetermined duration.
Running a Manual Defrost Cycle
Units are preprogrammed 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:
Refrigerators: Press the defrost button ("DEF" and ) for approximately 5 seconds. Repeat to
stop the defrost cycle.
Freezers: Press the defrost button (snowflake symbol and ) for approximately 3 seconds. Repeat
to stop the defrost cycle.
Safety & Warning
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. Please 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, please 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, please do not plug or unplug the cord with wet hands.
• During maintenance and cleaning, please unplug the unit.
Proper Grounding Required

Cleaning the Exterior of the Unit
• In order to properly care for the exterior surfaces of your unit, you must regularly clean the
stainless steel.
• Approved tools are soft cloths, microfibers, sponges, or plastic scouring pads.
• Do not use steel wool, caustic cleaners, or abrasive cleaners.

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.
