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. Water can contain impurities either 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.
