The Koolaire KDF-0250A 161 undercounter ice machine produces ice by running water over a cold evaporator plate, which then slowly freezes individual cubes. Once the cells are full, water flow continues until it runs over the ice thickness probe for 7 seconds and signals the start of the harvest cycle. The evaporator heats up with warm refrigerant, releasing cubes from their cells and dropping them into the ice bin. Once the bin is full and the damper is held down for 7 seconds, ice production stops. This unit can produce 256 pounds of ice with ideal ambient air and incoming water temperatures. Its average production capacity is 180 pounds, and its full cubes work well in most drinks since they melt slowly. However, full-cube ice does not cool as quickly as half-cube ice and does not take up as much space in glasses. The Koolaire KDF-0250A 161 undercounter ice maker stores 134 pounds in its bin, and its door slides up and under the machine top to aid in scooping ice.
