Water - Scotsman C0530SR-1 Technical 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 purgeed
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.
