Water - Scotsman Prodigy C0322 Technical & Service Manual

Water

The quality of the water supplied to the ice machine will have an impact on the time between cleanings and
ultimately on the life of the product. There are two ways water can contain impurities: in suspension or in
solution. Suspended solids can be filtered out. In solution or dissolved solids cannot be filtered, they must be
diluted or treated. Water filters are recommended to remove suspended solids. Some filters have treatment in
them for suspended solids. Check with a water treatment service for a recommendation.
RO water. This machine can be supplied with Reverse Osmosis water, but the water conductivity must be no
less than 10 microSiemens/cm.
Potential for Airborne Contamination
Installing an ice machine near a source of yeast or similar material can result in the need for more frequent
sanitation cleanings due to the tendency of these materials to contaminate the machine. Most water filters
remove chlorine from the water supply to the machine which contributes to this situation. Testing has shown
that using a filter that does not remove chlorine, such as the Scotsman Aqua Patrol, will greatly improve this
situation, while the ice making process itself will remove the chlorine from the ice, resulting in no taste or odor
impact.
Additionally, devices intended to enhance ice machine sanitation, such as the Scotsman Aqua Bullet, can be
placed in the machine to keep it cleaner between manual cleanings.
Water Purge
Cube ice machines use more water than what ends up in the bin as ice. While most water is used during ice
making, a portion is designed to be drained out every cycle to reduce the amount of hard water scale in the
machine. That's known as water purge, and an effective purge can increase the time between needed water
system cleaning.
In addition, this product has the capability to automatically vary the amount of water purged based on the purity
of the water supplied to it. The water purge rate can also be set manually. Adjustments of purge due to local
water conditions are not covered by warranty.
