Water Quality (ice making circuit)
• Potable
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 ltered out. In solution
or dissolved solids cannot be ltered, they must be
diluted or treated. Water lters are recommended
to remove suspended solids. Some lters have
treatment in them for dissolved 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 lters remove chlorine from the water
supply to the machine which contributes to this
situation. Testing has shown that using a lter 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.

Location:
While the machine will operate satisfactorily within the
air and water temperature limits, it will operate more
eciently when those temperatures are nearer the
lower limits. Avoid locations that are hot, dusty, greasy
or conned.
Options
Ice is made until it lls the bin enough to block an
infrared light beam inside the base of the machine. A
eld installed kit is available to adjust the maintained
ice level lower. The kit number is KVS.
The standard controller has excellent diagnostic
capabilities and communicates to the user through the
AutoAlert light panel, seen through the front panel.
Field installed kits are available that can log data and
provide additional information when the front panel is
removed. That kit number is KSBU. A similar kit adds
network connectivity, and its number is KSBU-N.

Options
Vari-Smart
Optional adjustable ice level control (KVS). When
this option is present there is an adjustment post and
an additional indicator light to the right of the four
indicator lights mentioned earlier.
The ultrasonic ice level control allows the user to
control the point that the ice machine will stop making
ice before the bin or dispenser is full.
Reasons for this include:
• Seasonal changes in ice used
• Planning to sanitize the bin
• Faster turnover for fresher ice
• Certain dispenser applications where maximum ice
level is not desired
Use of Adjustable Ice Level Control
There are several positions the ice level can be set to,
including O or Max (knob and label indicators lined
up), where it lls the bin until the standard bin control
shuts the machine o. See the kit’s instructions for
complete details including special instructions for
dispenser applications.
Rotate the adjustment post to the desired ice level.
The machine will ll up to that level and when it shuts

What to Do Before Calling for Service
Normal Operation
Ice:
The machine will make either aked or nugget ice,
depending upon the model. The ice will be produced
continuously until the bin is full. It is normal for a few
drops of water to occasionally fall with the ice.
Heat:
On remote models most heat is exhausted at the
remote condenser, the ice machine should not
generate signicant heat. Water cooled models
also put most of the heat from ice making into the
discharge water.
Noise:
The ice machine will make noise when it is in ice
making mode. The compressor and gear reducer will
produce sound. Air cooled models will add fan noise.
Some ice making noise could also occur. These
noises are all normal for this machine.
Reasons the machine might shut itself o:
• Lack of water.
• Does not make ice
• Auger motor overload
• High discharge pressure.
• Low refrigeration system pressure.
Check the following
1. Has the water supply to the ice machine or
building been shut o? If yes, the ice machine will
automatically restart within minutes after water begins
to ow to it.
2. Has power been shut o to the ice machine? If yes,
the ice machine will automatically restart when power
is restored.
3. Has someone shut the power o to the remote
condenser while the ice machine still had power? If
yes, the ice machine may need to be manually reset.
To Manually Reset the machine.
• Open the switch door
• Push and release the O button.
• Push and release the On button.
To Shut the Machine O:
Push and hold the O button for 3 seconds or until the
machine stops.
