FAQs

Q: What type of ice does the Avantco 194MN522A produce?
Ans: This machine creates soft, compact, and liquid-absorbing nugget-style ice, often known as chewable or pellet ice. It’s perfect for salad bars, drinks, smoothies, and medical applications.

Q: What is the daily ice production capacity?
Ans: Under ideal circumstances, the Avantco 194MN522A can generate up to 522 pounds of nugget ice each day (assuming an ambient temperature of 70°F and water temperature of 50°F).

Q: Does this unit come with an ice bin?
Ans: No, an external bin that is compatible with the ice maker head needs to be purchased independently. Avantco provides corresponding bins made to manage this unit’s production capacity.

Q: What power supply is required for this ice machine?
Ans: The device needs to be plugged into a specific outlet and properly grounded because it runs on a 115V electrical connection. 

Q: How long does it take to start producing ice after setup?
Ans: Depending on the water and surrounding temperature, the machine usually starts making ice 20 to 30 minutes after installation and initial startup.

Q: Can I install this machine under a counter or in an enclosed space?
Ans: No. This modular ice machine head is intended to be placed above an ice bin in an area with adequate ventilation. 

Q: Is a water filter required?
Ans: A water filter is not provided, although it is strongly advised. Reduced ice production, scale accumulation, and invalid warranties can result from using unfiltered water.

Q: What cleaning solutions should I use?
Ans: Use only ice machine cleansers and sanitisers that have been authorised by the manufacturer and are safe to use on surfaces that come into contact with food.
