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.

1. Remove the bottom vent by loosening the 4 screws that hold it in place. You do not need to fully remove the
screws as the vent will slide up and out.
2. Remove the top panel by unscrewing the 2 small screws. Once the screws are removed, the top panel will
hinge up.
3. Remove the small screws at the top and bottom door hinge where it attaches to the brackets.
Note: DO NOT lose the small washers.
4. Take o the top bracket by removing the 3 bolts.
5. The door should come o at this point.
Note: DO NOT lose the small round brass spacer on the bottom hinge.
6. Remove the 3 bolts holding the bottom bracket.
7. Replace the bottom hinge with the new left hand bottom bracket using 3 bolts.
8. 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.
This unit is intended for use in a temperature-controlled environment of less than 75°F and 60% relative
humidity. Malfunction due to improper conditions is not covered under warranty.
Tools Needed:
• Socket Set
• Pliers
• Adjustable Wrench
• Phillips Head Screwdriver
The Avantco A-19R, A-19F, A-23R, and A-23F ship with a right-hinged door design. If you would like to convert the

Adjusting the Temperature
Temperature Controls
• 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°F and a maximum temperature of 40°F.
• Freezers are set to cycle between a minimum temperature of -5°F and a maximum temperature of 2°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 Freezers (older models)
Refrigerators & Newer Freezers
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.

Cleaning the Condenser Coil
Cleaning the Condenser Coil Instructions
Cleaning
• If necessary, clean the fan blades and motor with a soft cloth.
• If it is necessary to wash the fan blades more thoroughly, cover the fan motor to prevent moisture damage, then
use a damp cloth to clean the fan blades.
• Use warm water and a mild soap with a clean cloth to wipe down the interior of the unit.
• 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 mild soap and warm water.
To remove the pilasters, first remove the shelves and shelf brackets. Then, simply lift the pilaster up and out.
• 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.
DISCONNECT POWER CORD BEFORE CLEANING ANY PARTS OF THE UNIT.
It is strongly recommended that any servicing of the unit be performed by an authorized service technician.
