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 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 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
The standard machine will make ice until ice lls
the bin and blocks an infrared light beam inside the
bottom of the machine. A eld installed kit is available
to adjust the ice level lower. That 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.
There is a eld installed kit 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.

The design of the oat valve and reservoir prevents
potable water backow by means of a 1" air gap
between the reservoir's maximum water level and the
oat valve water inlet orice.
Drain
There is one ¾” FPT condensate drain tting at the
back of the cabinet.
Tubing
Connect the potable water
supply to the potable water
tting, 3/8” OD copper tubing or
the equivalent is recommended.

Maintenance
This ice machine needs ve types of maintenance:
• Remote condensing units need their condenser coils
cleaned regularly.
• All models require regular scale removal
• All models require regular sanitization.
• All models require sensor cleaning.
• All models require a top bearing check.
Maintenance Frequency
Scale removal. To maintain proper machine
performance and sanitary condition, cleaning is
recommended every 6 months. The ice machine
will not maintain a sanitary condition without human
intervention.
The yellow Descale & Sanitize light will switch on
after a set period of 6 months as a reminder to
clean the machine. Some water quality conditions
may necessitate cleanings as frequently as every 3
months.
Sanitizing: Every time the scale is removed or as
often as needed to maintain a sanitary unit.
Sensor Cleaning: Every time the scale is removed.
Top bearing check: At least twice a year or every
time the scale is removed. During the course of
normal operation, some material buildup on top of the
bearing is normal and should be wiped away during
maintenance.
Maintenance: Remote Air Cooled Condenser
The condenser ns will occasionally need to be
cleaned of leaves, grease or other dirt. Check the coil
every time the ice machine is cleaned.
Maintenance: Exterior Panels
The front and side panels are durable stainless steel.
Fingerprints, dust and grease will require cleaning
with a good quality stainless steel cleaner
Note: If using a sanitizer or a cleaner that contains
chlorine on the panels, after use be sure to wash the
panels with clean water to remove chlorine residue.
Maintenance: Water Filters
If the machine has been connected to water lters,
check the cartridges for the date they were replaced
or for the pressure on the gauge. Change cartridges
if they’ve been installed more than 6 months or if the
pressure drops too much during ice making.

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
o the indicator light next to the adjustment post will
be On.
Note: The maximum ll position is when the arrow on
the knob points to the arrow on the label.

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. Air cooled models will generate heat,
and it will be discharged into the room.
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
