This manual provides essential instructions for the Avantco Vertical Open Air Merchandiser. Key operational requirements include maintaining an environment below 75°F and 65% relative humidity. If the unit was transported on its side, it must stand upright for at least 24 hours before plugging in. Always maintain a 6-inch clearance at the back for proper airflow.
Installation
Proper placement is critical for performance and warranty coverage:
- Surface: Install on a strong, level surface to prevent noise and malfunction.
- Environment: Use indoors only, away from direct sunlight, doors, air ducts, and fans.
- Clearance: Maintain at least 6 inches of clearance at the back of the unit.
- Conditions: Avoid high humidity and dusty areas, as these can cause rust and condenser failure.
Electrical Requirements
- The unit requires a dedicated, grounded, and properly-sized electrical outlet.
- Do not use extension cords.
- Do not plug or unplug with wet hands.
- After unplugging, wait at least 10 minutes before plugging back in to prevent compressor damage.
Temperature Adjustment
The unit is factory-set to cycle between 33°F and 40°F. To adjust the minimum temperature:
- Hold the SET button for 1 second until the display flashes.
- Use the arrow buttons to set the desired minimum temperature.
- Press SET again to save.
Note: The cabinet temperature will fluctuate up to +4 degrees above the set minimum.
Maintenance and Cleaning
- Condenser Coil: Clean at least once per month using a commercial condenser coil cleaner. Keep free of dust and lint.
- Fan Blades and Motor: Clean with a soft cloth. If washing, cover the motor to prevent moisture damage.
- Interior: Clean with warm water and mild soap. Do not use steel wool, caustic soaps, or bleach.
- Loading: Do not block the air duct/fan at the top. Maintain 4 inches of clearance between products and the fan.
Defrosting
The unit performs automatic defrost cycles. To run a manual defrost cycle, press the defrost button (snowflake symbol and down arrow) for approximately 3 seconds. Repeat to stop.
