Ice Making System

The ice making system is the continuous ow type. The main components of this system are:

• Refrigeration condensing unit

• Stainless steel, copper-wrapped evaporator.

• Stainless steel auger inside the evaporator

• Stainless steel extruding head and bearing retainer at the top of the evaporator

• Stainless steel, solid lube bearings top and bottom

• One/sixth HP auger drive motor and gear reducer

Ice is made whenever the control system detects an ice storage bin that is not full. The R-404A condensing unit
and auger drive motor switch on. The auger lifts soft, wet ice to the extruding head, where it is forced thru eight
slots, compressing it into a harder, usable stick-like form. Above the slots the head has a wedge, the extruded
ice sticks are forced against the wedge causing them to break off into short lengths. An ice sweep moves the
nished ice to a chute.

When ice begins to ow out of the top of the extruding head, water begins to ow into the bottom of the
evaporator from the water reservoir. Water rells the reservoir when the oat valve bulb drops. Ice is then
continuously owing into the ice storage bin.

Ice Dispensing System

The main components of the dispensing system are:

• Ice storage bin

• Ice dispense rotor

• Ice dispense agitator

• Ice dispense motor

When the control system detects a container in front of the ice dispense sensor, the controller connects power
to the ice dispenser motor.

The ice dispense motor then rotates the dispense rotor and dispense agitator. Together they force ice to the
outlet at the bottom front of the ice storage bin. Ice falls by gravity into the user’s container until either the user
removes it or until the control system times out. Ice is restricted from falling directly out of the bin by the ice
dispense chute cover, located above the chute and dispense rotor.
