Health & Safety topics
Before starting the presentation lets understand
safety:
• Physical Site / Location
• Safety exits for building
• Safe assembly area
• Electrical Hazards
• Voltage in Building
• Refrigeration
• We handle R404a refrigerant
• Gas Management / CO2
• Use this for fountain products
• Before installation please make sure you read
through the installation manual.

What Is Chunklet Ice?
• Also referred to as “Soft”, “Chewy”, or “Extruded” Ice.
• It is produced through continuous compression of ice
flakes… similar to a snowball.
• This process allows beverage to surround the ice and
cool faster and absorb into the ice.
• Nugget ice is also perfect for blended drinks.

Location:
Make Sure proper air clearances for proper circulation –
front and side on air cooled.
12” clearance on air Intake to be maintained.
4” clearance minimum on air exhaust.
Ice-Maker should not be placed in direct sunlight or
in close proximity of any object generating additional heat
load on system.
MODEL REQUIREMENTS REQUIREMENTS
WCC700A 110-126V/60HZ/1PH 20Amp Stand alone circuit breaker
Notes:
Unit has to be plugged with individual circuit breaker of 20 Amps, no other equipment should be connected to this circuit.
Voltage is –5% / +10% with the compressor running.
Discuss 1.5 KVA Buck / Boost Transformer (+/- 16/32VAC). Explain wiring diagram and the fact that only one leg is being increased or
decreased.
Drain:
Overflow line is a 3/8” i.d. flexible tubing, plumb to local guidelines.

How Ice is Made:
•The Cornelius Chunklet Ice Maker creates Ice in a process called extrusion.
•Ice is frozen to an evaporator wall until it grows thick enough to harvest. At that point the ice is shaved from the
wall by an auger and carried upwards to the extruding head.
•The extruding head is a finned device that forms or compresses the ice into its familiar Chunklet shape. As ice is
compressed by the extruder head, whatever remaining water there is on the surface of the ice will be squeezed away
leaving a uniformly shaped chunk of ice.
•The ice made in this process is soft and chewable yet resists bridging in Ice Drink dispensers when properly setup.
Use of a bin stat set to a lower point, agitation time adjustments, restrictor plate adjustment and addition of a diverter
plate assure this.

••
•Note that compression of the Ice takes
place at the top of the evaporator
assembly.
•The output shaft of GEARMOTOR
spins the auger with the extruding head
stationary, as the ice is driven up the
wall of the evaporator it compresses &
is extruded into the reservoir tray. The
upward movement of the ice pulls down
on the extruding head therefore the
thrust washers wear & need to be
replaced bi-annually.
Note: pictures from a WCC500
Extruder Assembly / Evaporator
Breakaway mounts – should the Ice Machine
not shut down these mounts are designed to
break & relieve auger pressure.
Extruder & Evaporator
The extruding oilite head bushing is replaceable. It is a special bushing that contains no lead
and needs to be pressed into the shaft. The thrust bearings will become worn and should be
replaced bi-annually or as needed.
