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

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.
Remove the top panel next. It is held on with 2 small screws. Once the screws are out, the top panel will hinge up.
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.
Next take off the top bracket. It is held on with 3 bolts.
The door should come off at this point.
Note: Do not lose the small round brass spacer on the bottom hinge!
Remove the bottom bracket. It is held on with 3 bolts.
Replace the bottom hinge with the new left hand bottom bracket. It is held on with 3 bolts.
At this point, you will need to adjust the top and bottom spring tensioners so the door will close properly.
Put the door on the bottom hinge on the left side. You will need to reuse the brass spacer from step 5.
Next, place the top bracket on the top of the door before bolting it to the unit with the 3 bolts.
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.
Reattach the bottom vent and the top panel.

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.
- 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 efficiency.
- 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.
- Malfunctions due to ambient temperatures above 75 degrees Fahrenheit will void the warranty.
- Do not install the unit inside a closet or alcove.

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
Refrigerator Control

Digital Control Units

Hold “SET” for 1 second. The display will flash the current minimum temperature.
Use the arrow buttons to adjust the minimum temperature you’d like the unit 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 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-off 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

Warning

Do not attempt to remove or repair any component unless instructed by factory.
Make sure that the unit is not resting on or against the electrical cord and plug.
To minimize personal injury, do not hang on the doors.
Do not store any flammable and explosive gas or liquids inside the unit.
Do not attempt to alter or tamper with the electrical cord.

Operation & Maintenance

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.

Loading the Product

Make sure there is at least four inches of clearance from the evaporator.
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 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 the 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 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.

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.

Cleaning the Condenser Coil

For efficient operation, keep the condenser surface free of dust, dirt, and lint.
We recommend cleaning the condenser coil at least once per month.
A dusty condenser may lead to high energy consumption, less cooling effectiveness, and compressor damage.

Condenser Coil Cleaning Instructions

The condenser coil is located at the bottom behind the panel.

Disconnect the electrical power from the unit.
Remove the front cover and base cover with a screwdriver.
Using a soft brush and/or vacuum, remove the dirt, lint, etc. from the finned condenser coil in a vertical direction.
Clean the condenser with a commercial condenser coil cleaner, available from any kitchen equipment retailer. Ex. Noble Chemical Tech Line.
After cleaning, straighten any bent condenser fins with a fin comb.
When finished, be sure to reinstall the front cover and base cover.
Reconnect the electrical power to the unit.
