WATER AND ICE CIRCUIT

The supply water enters the float chamber through a small orifice. The water level rises and lifts the float arm on

the float valve and seats the valve, shutting off the water supply when the water is at the desired level. As the

water leaves the float chamber, filling the evaporator, the float drops and allows additional water to enter refilling

the float chamber. Thus the water level is maintained automatically as the unit operates.

The water level in the evaporator shell will rise to the same level as the water in the float chamber. The water in

direct contact with the evaporator wall freezes and forms ice on the evaporator wall. As the freezing continues

the ice becomes thicker and exceeds the space between the evaporator wall and the auger. The auger rotating

at 8 RPM then chips off the ice and moves it to the surface of the shell. When the ice reaches the top surface of

the water in the shell it is pushed upward through the extruder opening into the cutter heads. From the cutter

head the ice enters the drop chute and falls into the storage bin. This action continues until the ice comes in

contact with the bin thermostat and the unit is shut down. The unit will remain off until the ice drops from the bin

thermostat through consumption or melting, at which time the unit will restart.
