12 Operation of Ice Machine

Your ice machine is unique in how it forms 

ice with fractional freezing to form a slab 

of ice that is clear and has less mineral 

content than the water it is produced from. 

This is accomplished by running water over 

the cold evaporator plate (Figure 1) which 

gradually freezes the water to produce the 

ice slab. Pure water freezes first, leaving the 

dissolved minerals in the residual reservoir 

water to provide clear ice.

When the ice slab reaches the correct 

thickness, the ice sheet is released and 

slides onto the grid cutter (Figure 2). Here, 

the ice slab is cut into squares by the 

grid cutter's heated wires (Figure 3). The 

water containing the dissolved minerals 

is drained after each freezing cycle. Fresh 

water enters the machine for the next ice 

making cycle.

The ice machine will keep producing ice 

until the ice machine's bin is full and will 

restart automatically when ice needs to 

be replenished in the bin. The ice bin is 

not refrigerated, and some melting will 

occur. Allow your ice machine to run for 

24-48 hours to accumulate ice in the ice 

machine's bin.
The bin level sensor is located in the ice 

bin, it senses when the ice supply is low 

or full and starts or stops the ice making 

process accordingly.

If the water supply is turned off to the 

ice machine be sure to set the electronic 

control to the "OFF" position.

"Initial" ice production and ice 

accumulated in the storage bin will vary 

significantly. This is normal. During the 

first 24 hours of operation the unit will 

produce about 30 lbs. of ice at the above 

temperature conditions, but when starting 

with an empty ice storage bin, the storage 

bin may only accumulate about 18 lbs. 

of ice. By design, the ice storage bin is 

maintained at a temperature slightly above 

freezing to allow the stored ice to slowly 

melt, to preserve the clarity and assure 

a constant supply of fresh ice. As ice is 

accumulated in the bin, the ice production 

rate will overcome the ice melt and the 

storage bin will fill to capacity.

In normal mode the ice machine will 

produce about 35 pounds (15.9 kg) of clear 

ice in a 24 hour period when installed in 

a 70°F ambient temperature with a 70°F 

water supply. In "ECO" mode (Controls 

section) the energy consumption and 

the amount of ice produced in a 24 hour 

period will be reduced by approximately 23 

percent.
