Installation
Please read this manual thoroughly prior to equipment set-up, operation and maintenance.
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 the unit stand upright for a
minimum of 24 hours before plugging it in.
• Make sure the unit has reached the desired temperature before loading the unit with products.
• Make sure all accessories are installed (shelves, shelf clips, etc…) 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 this manual in its entirety.
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
1. Remove the bottom vent, which is held on by loosening the 4 Phillips head screws that hold it on.
You do not need to remove the whole way, as the vent will slide up and out.
2. Remove the top panel next. It is held on with 2 small screws. Once the screws are out, the top
panel will hinge up.
3. Remove the small Philips head screws at the top and bottom door hinge where it attaches to the
brackets. Be careful not to lose the small washers.
4. Next take off the top bracket. It is held on with 3 bolts.

8. At this point, you will need to adjust the top and bottom spring tensioners so the door will close
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.
11. Replace the small screws on the top and bottom of the bracket and door spring. Make sure the
door is on properly before you do this.
12. Reattach the bottom vent and the top panel
Cabinet Location Guides
• 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, maintain 6” of clearance on both sides and the back of the unit at all times.
- Outdoor use may cause decreased efficiency and damage to the unit.
- Avoid direct sunlight.
• Avoid installation in a high humidity and / or dusty area.
- High humidity can cause the unit to rust and may decrease efficiency.
- Dust collected on the condenser coil may cause unit to malfunction.
- Malfunction due to high ambient temperatures, humidity, or improperly maintained
condenser coil will void the warranty.
• Select a location away from heat and moisture-generating equipment.
- High ambient temperatures may cause the compressor to malfunction.
- Malfunction due to high ambient temperatures and humidity will void the warranty.

User Manual
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.
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 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 differential 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 off. Setting the temperature too high will result in unsafe maximum
temperatures and possible health code violations.

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 (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-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.
Operation/Maintenance
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. Maintain a minimum of 4” of clearance
between products and the fan at all times.
• 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 Condensor Coil
• For efficient operation, keep the condenser surface free of dust, dirt, and lint.

- 7 -
User Manual
• We recommend cleaning the condenser coil at least once per month.
• Clean the condenser with a commercial condenser coil cleaner, available from any kitchen
equipment retailer.
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 the door gasket from the
frame of the door, soak it in warm water and soap for thirty (30) minutes, then dry with soft cloth
and replace.
• Check door gaskets for proper seal after they are replaced.
• Periodically remove the shelves and shelf brackets from the unit, and clean them with a mild soap
and warm water.
