This manual covers the installation, operation, and maintenance of Avantco Refrigerated Deli Cases. Before using the equipment, ensure it has been allowed to stand upright for at least 24 hours if it was transported on its side. The unit is factory-set to optimal temperatures for food safety and should not require immediate adjustment.
Installation
Proper installation is critical for the performance and longevity of the unit:

- Surface: Install on a strong, level surface to prevent noise and malfunctions.
- Clearance: Maintain at least 6 inches of clearance on the front and back of the unit for proper ventilation.
- Environment: Install indoors in a well-ventilated area. Avoid direct sunlight, high humidity, and dusty environments.
- Placement: Keep away from heat and moisture-generating equipment.
Electrical Requirements
- The unit requires a dedicated, grounded, and properly-sized electrical outlet.
- Do not use extension cords.
- Ensure the unit is not resting on the power cord.
- If the unit is unplugged, wait at least 10 minutes before plugging it back in to avoid compressor damage.
Temperature Controls
The unit is factory-set to run at optimal temperatures. Refrigerators cycle between 33°F and 40°F, while freezers cycle between -5°F and 2°F. To adjust the minimum temperature:

- Hold the "SET" button for 1 second until the display flashes.
- Use the arrow buttons to adjust the desired minimum temperature.
- Press "SET" again to save the settings.
Note that the cabinet temperature will fluctuate up to +7 degrees above the set minimum as the compressor cycles.
Defrosting
Units are pre-programmed for automatic defrost cycles. To run a manual defrost cycle (only on digital control models):
- Freezers: Press the "def" button and down arrow for approximately 5 seconds.
- Refrigerators: Press the defrost button (snowflake symbol and down arrow) for approximately 3 seconds.
Maintenance
- Loading: Do not block the coil. Ensure shelves are level and secured. Do not store flammable or explosive materials.
- Condenser Coil: Clean at least once per month using a commercial condenser coil cleaner. Keep free of dust and lint.
- Interior: Clean with warm water and mild soap. Do not use steel wool, caustic soap, or abrasive cleaners.
- Fan Blades/Motor: Clean with a soft cloth if necessary. Cover the motor to prevent moisture damage when washing.
Troubleshooting
If the unit is not performing correctly, check the following:
- Compressor not running: Check for a blown fuse, tripped breaker, unplugged cord, or if the unit is in a defrost cycle.
- Temperature too warm: Check if the thermostat is set too high, airflow is blocked, the door is ajar, or if refrigerant levels are low.
- Interior light not working: Check the switch, bulb connection, or replace the bulb.
- Condensation: Ensure the door is fully closed.
