Koolaire and Manitowoc Float Parts September 23 2014, 0 Comments

Manitowoc float valves are not the same as Koolaire float switches.  The terminology can sometimes be confusing, but there is a difference and they are not interchangeable.  The biggest difference is that Manitowoc will use a float valve, where Koolaire uses a float switch.  This means that water does not actually pass through the Koolaire float, it will only read the level in the water trough.

Float valves are also typically only used on older ice machines or undercounter models.  Modular units and modern Manitowoc ice machines rely on a separate water inlet valve, that provides a higher rate of water flow.  Because they can bring in more water and operate on cycles, they are more energy efficient.  A water float valve will simply let water in, anytime the float drops, wasting water.  The Koolaire ice machine uses a combination of the two technologies.


Ice Thickness Float Switch Adjustment on Koolaire August 13 2014, 2 Comments

Ice machines require the proper ice thickness or bridge thickness, to properly harvest.  Setting this thickness allows for faster harvest cycles, depending on condition and customer preference on cube size.  Manitowoc and Koolaire recommend a 1/8" thick bridge on all of their cuber ice machines.  Adjusting a Koolaire ice thickness is unique, because harvest is triggered by a float switch and not an ice thickness probe.

To adjust the float switch, you will need a 3/4" wrench.  Use the wrench on the float switch located on the left, as you are facing the front of the machine, to loosen or tighten the nut located right above the white plastic float.  Turn the float switch clockwise to increase thickness and counterclockwise to decrease.
