OPERATION, CARE, AND CLEANING OF YOUR ICE MACHINE
Operation (Turning on the ice machine)
Once the drain and water supply are connected, and the ice
machine is in place and leveled, plug in the service cord. Place
the switch to the “ON” position to turn on the ice machine. The
switch is located in the front grille, see Figure 16 for location.
The Ice Making Process
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 (see Figure 15)
which gradually freezes the water to produce the ice slab. Min-
eral deposits are left in the reservoir.
Figure 15
When the ice slab reaches the correct thickness, the ice sheet is
released and slides onto the grid cutter (see Figure 17). Here, the
ice slab is cut into squares by the grid cutter’s heated wires (see
Figure 18). The water containing the rejected minerals is drained
after each freezing cycle. Fresh water enters the machine for the
next ice making cycle.

Make sure the distributor
tubing is not in the path
of the ice slab.

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.
