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.
Water pressure limit to water cooled condenser is
150 PSI

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.
Warranty Information
The warranty statement for this product is provided
separately from this manual. Refer to it for
applicable coverage. In general warranty covers
defects in material or workmanship. It does not
cover maintenance, corrections to installations, or
situations when the machine is operated in
circumstances that exceed the limitations printed
above.

Installation and Use
Location:
While the machine will operate satisfactorily within
the listed air and water temperature limits, it will
produce more ice when those temperatures are
nearer the lower limits. Avoid locations that are hot,
dusty, greasy or confined. Air cooled models need
plenty of room air to breathe. Air cooled models
must have at least six inches of space at the back
for air discharge; however, more space will allow
better performance.
Airflow
Air flows into the front of the cabinet and out the
back. The air filters are on the outside of the front
panel and are easily removed for cleaning.
Bin compatibility
All models have the same footprint: 22 inches wide
by 24 inches deep. Confirm available space when
replacing a prior model.
Bin & adapter list:
B222S or B322S – no adapter needed
•
B330P or B530P or B530S – Use KBT27
•
B842S – KBT39
•
B948S – KBT38 for single unit
•
B948S – KBT38-2X for two units side by side
•
BH1100, BH1300 and BH1600 upright bins
•
include filler panels to accommodate a 22
inch wide ice machine. No adapter is
needed.
BH900: Use baffle kit KBBF1 for these models.
Dispenser compatibility
Airflow
Options
Side air flow kits KPFSA223 or KPFSA227 are
available for air cooled models. A filter kit for the
remote condenser is KERCF
Ice is made until it fills the bin enough to either
block an infrared light beam inside the base of the
machine or reflect ultrasonic waves to a sensor in
the base.
Additionally the control system includes an
information panel which is visible when the front
panel is removed.
Only nugget ice models may be used with ice
dispensers. Flaked ice is not dispensable.
