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 airflow. Failure to install the shelves properly is considered a 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.
  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 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 the 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.

Field Convertible Doors

The Avantco AP-23R and AP-23F models ship with a right-hinged door design. These single door models have the ability to be switched to a left-hinged door design. Please  follow the instructions below:
Tools Needed:

• Phillips Head Screwdriver
• 10mm Wrench

1. Use the Phillips head screwdriver to remove the front panel screws, followed by the front panel.
2. Use the wrench to remove the bottom hinge hex screw, then loosen the hinge screws and carefully remove the door.
3. Use the screwdriver to remove the bottom and top hinges.
4. Use the wrench to remove the bolt of the top hinge, then install the bolt into the bottom hinge.
5. Install the bottom right hinge in the top left side of the equipment. Then, install the top right hinge in the bottom left side of the equipment.
6. Remove the bottom cartridge and bolt housing from the door, install the cartridge at the top of the door and the bolt housing in the bottom.
7. Remove the top head screws, then move the hinge cap to the right side. Reinstall the top head screws.
8. Install the hinges on the left side, but do not tighten the screws. Then, install the door and cartridge screwTighten all screws.
9. Reinstall the front panel with the hinge cap on the right side.

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 32°F and a maximum temperature of 38°F.
Freezers are set to cycle between a minimum temperature of -8°F and a maximum temperature of 0°F.
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 +6°F for refrigerators and +8°F  for freezers 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.

Control Panel

ECO Mode

The unit enters Eco Mode automatically if the doors have not been opened for 2 hours and will be kept in this mode for 4 hours or if a door opening is detected for more than  6 seconds. When the cycle ends or a door is opened, the unit will return to normal operating mode.
ECO Mode raises the temperature of SETPOINT by 4°F, so the compressor will work less while maintaining stable temperatures inside. This helps the unit when the premises are closed, allowing the equipment to save energy without compromising product temperatures. When the doors remain closed, the temperatures inside the equipment are more stable and you do not need to take the compressor to set  POINT.
It should be noted that this function of ECO Mode only works for periods of 4 hours as long as the doors do not open.

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:

Refrigerators: Press the defrost button (down arrow) for approximately 3 seconds. Repeat to stop the defrost cycle.
Freezers: Press the defrost button (down arrow) for approximately 5 seconds. Repeat to stop the defrost cycle.

Defrost System

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 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.
• 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 a soft cloth and replace it.
• Check door gaskets for proper seals after they are replaced.
• Periodically remove the shelves and shelf brackets from the unit, and clean them with mild soap and warm water.
