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.
Minimum conductivity (RO water)
• 10 microSiemens / CM
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.

Location:
While the machine will operate satisfactorily within the
air and water temperature limits, it will operate more
efciently 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 KSB-NU.
Bin compatibility
All models are the same width: 22 inches. All models
are the same depth: 24 inches.

Unpacking
Remove the carton from the skid. Check for hidden
freight damage, notify the carrier immediately if any is
found. Retain the carton for the carrier’s inspection.
The machine is not bolted to the skid. If strapped
remove the strap.
Place on Bin or Dispenser
If reusing an existing bin, be sure that the bin is in
good shape and that the gasket tape on the top is not
torn up. Water leaks, not covered by warranty, could
result from a poor sealing surface. Because this is a
remote low side, a new bin is recommended due to
the high cost to the user of replacing an old bin when
a remote system is on top.
Install the correct adapter, following the directions
supplied with that adapter.
Hoist the machine onto the adapter.
Note: The machine is heavy! Use of a mechanical lift
is recommended.

with straps from the hardware bag packed with the
machine, or those supplied with the adapter.
Remove any plastic covering the stainless steel
panels.
Remove any packaging, such as tape or foam blocks,
that may be near the gear reducer or ice chute.
Level the bin and ice machine front to back and left to
right by using the bin leg levelers.
1. Locate and loosen the two screws at the bottom
edge of the front panel.
2. Pull the front panel out at the bottom until it clears
the bin.
3. Lower the front panel down and off the machine.
4. Remove two screws at the front of the top panel.
Lift up the front of the top panel, push the top panel
back an inch, then lift to remove.

Water
The water supply for ice making must be cold, potable
water. There is a single 3/8” male are potable water
connection on the back panel.
Backow
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.
Connect the drain tube to the
condensate drain tting. Vent this
drain tube.
Do not Tee ice machine drains
into the drain tube from the ice
storage bin or dispenser. Back
ups could contaminate and
/ or melt the ice in the bin or
dispenser.

Initial Start Up
1. Turn the water supply on.
2. Switch the electrical power on. Conrm voltage is
correct for the model.
3. Push and release the On button. The machine will
start up in about two minutes.
The liquid line valve will open and liquid refrigerant
will ow into the machine. For the units connected to
a dedicated condensing unit, the resulting increase in
suction pressure will start the condensing unit and the
condensing unit will begin discharging warm air from
the remote condenser. After about 5 minutes, ice will
begin to drop into the bin or dispenser.
4. Check the machine for unusual rattles.
5. Tighten any loose screws, be sure no wires are
rubbing moving parts. Check for tubes that rub.
6. Check suction pressure, adjust EPR setting. As
shipped the EPR valve should maintain low side
pressure at about 36 PSIG + or - 2 PSIG.
Note: Machines will operate and make ice at the
factory EPR setting. For optimum performance, adjust
the EPR to the settings in the chart below:
• All models require sensor cleaning.
• All models require a top bearing check.
Maintenance Frequency:
Scale removal. At least twice a year, in some water
conditions it might be every 3 months. The yellow De-
Scale & Sanitize light will switch on after a set period
of time as a reminder. The default time period is 6
months of power up time. There are 4 available time
period intervals: 1 year, 0 or disabled, 6 months or 4
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.
Maintenance: Remote air cooled condenser
