Temperature Controls

Adjusting the Temperature

• Your new refrigerator 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.
• 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

Temperature Controller Operation

1. Set temperature:
2. Press or to modify the displayed value.
3. If no additional buttons are pressed within 10 seconds, the unit’s current temperature will be displayed.
4. Lights: Press the button to turn the lights ‘on’ or ‘off.’ Manual start/stop defrost: Press the button and hold for 6 seconds to defrost or stop defrosting.
5. Refrigerant LED: When the compressor is running, the LED is on; when the refrigerator temperature is constant, the LED is off. During the delay start, the LED flashes.
6. Defrost LED: During the defrost cycle, the LED is on; when it stops defrosting, the LED is off. During the delayed display of defrost, the LED flashes.
7. Defrost System
8. If a drainage pipe is available, lower the condensation drainage pipe and connect it to a drain or condensation pump. Verify the pipe is unobstructed and it is lower than the water receiver indicated by the line on the sticker.

Loading Product

• Ensure there is at least 4″ of clearance from the evaporator.
• Ensure all shelves are sitting level and properly secured before loading products.
• DO NOT store flammable/explosive gas or liquids inside the unit.

Operation

• Adjusting the Temperature of the Top Bakery Case Section
• Four perforated baffles come installed on the unit for the unit to operate with a fully refrigerated top section.
• The baffle will prevent (solid) or allow (perforated) refrigerated air from circulating through the display area and returning through the air return grille.
• The top bakery case section of the equipment can be ambient, refrigerated, or 50/50 ambient and refrigerated.
  

• For 50/50 ambient and refrigerated, position two solid baffles in the middle of the case, intended to be ambient to block airflow.
  

Cleaning

Fan Blades & Motor

• 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.

Interior

• 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 regularly, preferably weekly. Simply remove the door gasket from the frame of the door, soak it in warm water and soap for thirty (30) minutes, dry it with a soft cloth, and replace it.
• 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 Condenser Coil

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

FAQs

Q: What is the Avantco 193CAC36B Air Curtain Merchandiser designed for?
Ans: For grab-and-go merchandising of cold beverages, packaged foods, dairy, and other perishable goods, the 193CAC36B is a commercial open-air display refrigerator. To maintain safe temperatures while permitting unrestricted consumer access, it employs a refrigerated air curtain.

Q: How does the “air curtain” feature work?
Ans: An invisible barrier that helps keep cold air within the unit is created by the air curtain, a high-velocity sheet of chilled air that descends from the top front. This keeps interior temperatures constant while enabling clients to readily access things without a physical door.

Q: What are the dimensions and capacity of this unit?
Ans: With many tiers of shelves and a total display capacity of 12–14 cubic feet, the 193CAC36B is about 36 inches wide. It’s perfect for medium-volume merchandising in convenience stores, supermarkets, and coffee shops.

Q: What temperature range does this merchandiser maintain?
Ans: The unit’s design keeps food and drinks safely cold for short-term display and sale by maintaining items between 33°F and 40°F (0.5°C and 4.4°C).

Q: Can I use this merchandiser outdoors or in unconditioned spaces?
Ans: No, this device should only be used inside, where the temperature should be between 75°F (24°C) and 55% relative humidity. Using it in hot or muggy conditions could reduce cooling efficiency and raise energy usage.

Q: How often should I clean the condenser coil?
Ans: Depending on your environment, clean the condenser coil at least every 30 to 60 days to preserve efficiency. A buildup of dust and grease might make the equipment overheat or impair cooling.
