  • Page 8: How Ice Is Made

    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.
  • Page 9 Water System Overview Water level in the reservoir should be set to the water level line while  • operating. Looking at the center picture take note that with proper water level  setting the top evaporator coil should be covered with water.  During installation the float should be verified for: • Proper water level. • • System safety shutdown. Typically water pressure would be regulated if greater than 50 psi. • Make provisions for plastic tubing overflow lines as well. •  • • ...

Simply observe the ice coming out of the extruder head during production. As the auger rotates, an ice chunklet should pop out of each extruder slot on every rotation.

  • Page 19: Preventative Maintenance Procedures

    Preventative Maintenance Procedures Evaporator Squealing • Squealing noises coming from the evaporator are accompanied by low production. These noises are caused by a “rotational freeze”. A  rotational freeze is usually caused by mineral buildup on the evaporator walls. These deposits are not always visible, especially when the  evaporator is wet. The production of ice depends on the ice freezing to the wall of the evaporator and being shaved off by the auger. • The evaporator wall is belt sanded to create scratches from top to bottom. These scratches give the ice something to hold onto, preventing  it from rotating with the auger. If the grooves become filled with mineral deposits, the ice will not have any grip on the evaporator and  begin to rotate, instead of being shaved and pushed upward. The squealing noise is caused by the ice continuing to expand as it rotates. • Ice sticking together in the bin is almost always the result of water chemistry. High concentrates of minerals in the water, chlorine, and  salinity are usually found to be the cause. Filters that are specially designed for cubed ice makers usually contain chemicals called  phosphates. These phosphates will prevent minerals from freezing into the ice cubes as the bind with the impurities, this will allow the  purest water to freeze first and the mineral laden water to be dumped during the harvest cycle. The WCC Chunklet use 100% of their  water, if phosphate feeders are used the minerals have no choice but to fill the bin with the Chunklet – should not use. Once there it  behaves like salt causing the ice to breakdown and potentially stick together, this can result in damaged agitator blades or a large block of  ice (snow cone) may form due to clumping together. Therefore for phosphate feeders and scale inhibitors should not be used with  Chunklet ice.  • • ...
  • Page 20 Preventative Maintenance Procedures ICEMAKER CLEANING AND SANITIZING PROCEDURES  • WARNING: Do not use any of the ice made during cleaning operations. Clean and sanitize ice storage area when cleaning icemaker.  • Turn machine off. • Shut off water supply. • Remove ice from storage bin. • Mix approved cleaner (2 gallons as directed). Recommended cleaner: Nu‐Calgon liquid ice machine cleaner. Mixture: 3‐1/3 ounces per  gallon of water. Cleaner must be safe for stainless steel. NO EXCEPTIONS.  • • Clean auger/diverter assembly and ice transition/drop tube in a sink using cleaner mixture and reinstall in icemaker. Using cleaner,  wipe down the dispense tray.  • Turn machine on and add cleaner solution to water level control until 2 gallons have been used.  • Turn on water supply and run machine for 15 minutes.  • Turn off machine and remove all ice. • Sanitize using household liquid bleach (50 ppm chlorine). Mixture: 1 fluid ounce per gallon room temperature water. 2 minute  exposure time.  • Sanitize auger/diverter assembly and ice transition/drop tube in a sink using sanitizing solution and reinstall in icemaker. Using  sanitizer, wipe down the dispense tray.  • Fill icemaker with sanitizer by slowly pouring solution into water feed reservoir until full. Solution will drain through overflow tube. Do  not run machine. Allow to air dry.  • If icemaker is used in conjunction with ice dispenser or storage bin, follow manufacturer’s recommended cleaning instructions at this  time. ...
  • Page 21 Preventative Maintenance Procedures • MAINTENANCE Preventive maintenance can increase the trouble free life of your icemaker.  • Many authorized service agencies offer service contracts for your icemaker.  • Monthly 1. Clean the condenser. Use a brush, vacuum cleaner or blow from inside with air or CO2 gas. • Inspect water feed reservoir at least once a month until a definite pattern for cleaning and sanitizing has been established. • Quarterly This is the maximum period of time between cleaning and sanitizing the icemaker. In addition to recommended monthly procedure, and if a more frequent cleaning and sanitizing pattern has not been established, unit must be cleaned and sanitized.
