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.

Air, Water or Remote Service Manual
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 conned. 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.
Airow
Air ows into the front of the cabinet and out the back.
The air lters 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. Conrm available space when
replacing a prior model.
Bin & adapter list:
• 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
ller panels to accommodate a single 22 inch wide
ice machine. No adapter is needed.
Dispenser compatibility
Only nugget ice models may be used with ice
dispensers. Flaked ice is not dispensable.
Options
Side air ow kits KPFSA223 or KPFSA227 are
available for air cooled models. A lter kit for the
remote condenser is KERCF
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. The kit numbers are KSBU and KSB-NU.
See page 21.
• ID150 – use KBT42 and KDIL-PN-150, includes
KVS, KNUGDIV and R629088514
• ID200 – use KBT43 and KNUGDIV and KVS
• ID250 – use KBT43 and KNUGDIV and KVS
See sales literature for other brand model ice and
beverage dispenser applications.

Unpacking & Install Prep
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. If
installing a remote or 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.
Position the machine on the bin or adapter. Secure
with straps from the hardware bag packed with the
machine, or those supplied with the adapter.
Remove any plastic covering the stainless steel
panels.
Note: The standard machine set up includes visible
on and off switches. Those can be covered up by
changing the bezel in the front panel’s trim strip. A
cover-up bezel is included with the hardware bag.
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.
Panel Removal A or B Series
1. Locate and loosen the two screws at the front edge
of the top panel.
2. Pull the front panel out at the top until it clears the
top panel.
3. Lift the front panel up 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.
5. Locate and loosen the screw holding each side
panel to the base. Left side panel also has a screw
holding it to the control box.
6. Pull the side panel forward to release it from the
back panel.
Button Switch Bezel A or B Series
To change bezels: Remove the front panel, and refer
to the instruction label on the inside of the front panel.
Push snaps of standard bezel in and pull the bezel
out of the front panel trim strip.
Locate other bezel. Push into the trim strip from the
front until it snaps into place. Return the front panel to
its original position and secure it to the cabinet.
Panel Removal D Series
1. Locate and loosen the two screws at the bottom of
the front panel.
2. Pull the front panel out at the bottom until it clears.
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.
5. Locate and loosen the screw holding each side
panel to the base. Left side panel also has a screw
holding it to the control box.

Refrigeration - Remote Condenser Models
Remote condenser models have additional installation
needs.
The correct remote condenser fan and coil must
be connected to the ice making head. Liquid and
discharge tubing connections are on the back of the
ice machine cabinet. Pre-charged tubing kits are
available in several lengths to accommodate most
installations. Order the one that just exceeds the
length needed for the installation.
The kit numbers are:
• RTE10
• RTE25
• RTE40
• RTE75
There are limits as to how far away from the ice
machine and where the remote condenser can be
located. See the next page for those limits.

Do not reuse condenser coils contaminated with
mineral oil (used with R-502 for example). They will
cause compressor failure and will void the warranty.
The correct condenser must be used.

Note: A headmaster is required for all remote
condenser systems. Prior condensers did not have
a headmaster. New head / old condenser retrots
can use headmaster kit KPFHM. See chart below for
applications.

Remote Condenser Location - Limits
Use the following for planning the placement of the
condenser relative to the ice machine
Location Limits - condenser location must not exceed
ANY of the following limits:
• Maximum rise from the ice machine to the
condenser is 35 physical feet
• Maximum drop from the ice machine to the
condenser is 15 physical feet
• Physical line set maximum length is 100 feet.
• Calculated line set length maximum is 150.
Calculation Formula:
• Drop = dd x 6.6 (dd = distance in feet)
• Rise = rd x 1.7 (rd = distance in feet)
• Horizontal Run = hd x 1 (hd = distance in feet)
• Calculation: Drop(s) + Rise(s) + Horizontal
Congurations that do NOT meet these requirements
must receive prior written authorization from
Scotsman to maintain warranty.
Do NOT:
• Route a line set that rises, then falls, then rises.
• Route a line set that falls, then rises, then falls.
Calculation Example 1:
The condenser is to be located 5 feet below the ice
machine and then 20 feet away horizontally.
5 feet x 6.6 = 33. 33 + 20 = 53. This location would be
acceptable
Calculation Example 2:
The condenser is to be located 35 feet above and
then 100 feet away horizontally. 35 x 1.7 = 59.5.
59.5 +100 = 159.5. 159.5 is greater than the 150
maximum and is NOT acceptable.
• Run = dd+rd+hd = Calculated Line Length
rd Max 35 feet
22.87"
dd Max 15 feet
Operating a machine with an unacceptable
conguration is misuse and will void the warranty.

For The Installer: Remote Condenser
Locate the condenser as near as possible to the
interior location of the ice machine. Allow it plenty of
space for air and cleaning: keep it a minimum of two
feet away from a wall or other rooftop unit.
Note: The location of the condenser relative to the ice
machine is LIMITED by the specication on the prior
page.
Roof penetration. In many cases a roong contractor
will need to make and seal the hole in the roof for the
line sets. The suggested hole diameter is 2 inches.
Meet all applicable building codes.
Roof Attachment
Install and attach the remote condenser to the roof
of the building, using the methods and practices of
construction that conform to the local building codes,
including having a roong contractor secure the
condenser to the roof

Precharged Line Routing - Remote Only
Do not connect the precharged tubing until all routing
and forming of the tubing is complete. See the
Coupling Instructions for nal connections.
1. Each set of pre-charged tubing lines contains
a 3/8” diameter liquid line, and a 1/2” diameter
discharge line. Both ends of each line have quick
connect couplings.
Note: The openings in the building ceiling or wall,
listed in the next step, are the minimum sizes
recommended for passing the refrigerant lines
through.
2. Have the roong contractor cut a minimum hole
for the refrigerant lines of 2”. Check local codes,
a separate hole may be required for the electrical
power supply to the condenser.
Caution: Do NOT kink the refrigerant tubing while
routing it.
3. Route the refrigerant tubes thru the roof opening.
Follow straight line routing whenever possible.
4. Excess tubing may EITHER be coiled up INSIDE
the building OR cut out prior to connection to the
ice maker and condenser.
If the excess tubing is cut out, after re-brazing the
tubing must be evacuated prior to connection to the
ice maker or condenser.
If the excess tubing is to be coiled, spiral it
horizontally to avoid excess trapping in the lines.
5. Have the roong contractor seal the holes in the
roof per local codes

Coupling Instructions - Remote Only
The couplings on the ends of the pre-charged line
sets are self-sealing when installed properly.
Follow these instructions carefully.
These steps must be performed by an EPA Certied
Type II or higher technician.
Initial Connections
1. Remove the protector caps and plugs. Wipe the
seats and threaded surfaces with a clean cloth to
remove any possible foreign matter.
2. Lubricate the inside of the couplings, especially
the O-rings, with refrigerant oil. Oil packets are
supplied with Scotsman line sets.
3. Position the ttings on the correct connections on
the condenser and ice machine.
Final Connections:
4. Tighten the couplings together by hand until it is
certain that the threads are properly engaged.
6. Continue tightening the swivel nut until it bottoms
out or a very denite increase in resistance is felt
(no threads should be showing).
Critical Step!!!!!
7. Mark a line on the coupling nut and unit panel.
Then tighten the coupling nut an additional one-
quarter turn. The line will show the amount that
the nut turns. Do NOT over tighten.
5. Use two wrenches tighten the coupling until it
bottoms out or a denite increase in resistance is
felt. It is important that ONLY the nut on the pre-
charged tube be turned, or the diaphragms will
be torn out by the piercing knives and they will be
loose in the refrigeration system.
Note: As the couplings are tightened, the diaphragms
in the quick connect couplings will begin to be
pierced. As that happens, there will be some
resistance to tightening the swivel nut.

8. After all connections have been made, and after
the receiver outlet valve has been opened (do not
open yet), check the couplings for leaks.
