Water
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.
Scotsman lters:
A triple head lter is recommended for the potable
water. Either the Scotsman SSM3 taste and odor lter
system, or the ADS-AP3 AquaPatrol™ system. RO
water. This machine can be supplied with Reverse
Osmosis water, but the water conductivity must be no
less than 10 microSiemens/cm.
Condenser Water Supply - ltration not recommended
for this water supply
Water Flush
Cube ice machines use more water than what ends
up in the bin as ice. While most water is used during
ice making, a portion is designed to be drained out
every cycle to reduce the amount of hard water scale
in the machine. That’s known as water purge, and an
eective purge can increase the time between needed
water system cleaning.
In addition, this product has the capability to
automatically vary the amount of water purged based
on the purity of the water supplied to it. The water
purge rate can also be set manually.
Adjustments of purge due to local water conditions
are not covered by warranty.

MC1448W 70
MC1848W 106
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
AquaPatrol™, will greatly improve this situation, while
the ice making process itself will remove the chlorine
from the ice, resulting in no taste or odor impact.
Additionally, devices intended to enhance ice machine
sanitation, such as the Scotsman AquaBullet®, can
be placed in the machine to keep it cleaner between
manual cleanings.

Uncrate and Set Up
Begin with unpacking the ice storage bin. Remove the
carton, and using part of the carton as a cushion, tip
the bin on its back to remove the skid and attach the
legs or casters.
Note: Turn the leg levelers in all the way and adjust
after the ice machine is on top and in its selected
location.
Return the bin to an upright position. Check the bin
top gasket for gaps and tears, ll any in with food
grade sealant prior to placing the ice machine on the
bin.
Install the bin top adapter if one is required for the
application.
If the ice machine has not been unpacked, do so now.
Remove the carton from the skid. Lift the ice machine
o the skid directly onto the bin.
Note: The machine is heavy! Use a mechanical hoist
if necessary.
Secure the ice machine to the bin with the hardware
provided (two metal straps and 4 bolts).
Place the bin and ice machine in the selected location
and level it by adjusting the bin leg levelers.
• The used bin should be the proper size for the ice
machine head.
Lower Light and Switch Panel
This user accessible panel provides important
operational information and duplicates the lights and
switches on the controller. It also allows access to the
On and O buttons that operate the ice machine.
Sometimes access to the switches should be limited
to prevent unauthorized operation. For that purpose a
xed panel is shipped in the hardware package. The
xed panel cannot be opened.
To install the xed panel:
1. Remove the front panel.
2. From the back side of the panel, slide the door
to left while spreading the clips to remove the
original door from the bezel.
3. Slide the xed panel into bezel until it snaps into
place.
4. Reinstall front panel.
Open door to access On
and O switch buttons.
Remove the white plastic covering the panels.
Bin Recycling
Many times an ice machine head will be replaced,
while the existing ice storage bin will be reused. This
is an acceptable practice, if some precautions are
taken:
• The used bin must be in good condition. Broken
doors, hinges, or warped walls are reason for
considering a new bin.
• The used bin top edge gasket must be replaced.
Water leaks could occur if the gasket tape is not
replaced.

Air and Water Cooled User Manual
Plumbing Requirements
All models require connection to cold, potable water.
A hand actuated valve within site of the machine is
required.
Air cooled models have a single 3/8” FPT inlet water
connection.
Water cooled models have a 1/2" FPT drain tting
plus an additional 3/8” FPT condenser inlet water
connection.
Field Supplied
Inlet Water Connection
1. Connect water supply to water inlet ttings.
Note: This NSF listed model has a 1" anti-back
ow air gap between the end of the water inlet tube
and the highest possible reservoir water level, no
additional back ow device is required for the potable
water inlet.
2. Connect drain tubing to drain ttings.
3. Route the drain tubing to building drain. Follow
local codes for air gap.
Use rigid drain tubes and then route them separately
– do not Tee into the bin’s drain or, if water cooled,
Tee the condenser drain into the reservoir or bin drain.
Vent the reservoir drain. A vertical vent at the back of
the drain, extended about 8 - 10” will allow the gravity
drain to empty and also keep any surges during
draining from discharging water out the vent.
Insulate drain tubing if in a humid environment.
Horizontal runs of drain tubing need a 1/4” per fall per
foot of run for proper draining.
Water Filters
If connecting to water ltration, lter only the water
to the reservoir, not to the condenser. Install new
cartridges if the lters were used with a prior machine.
A triple head lter is recommended. Either the
Scotsman SSM3 taste and odor lter system, or the
ADS-AP3 AquaPatrol™ system.
Drains
All models require drain tubing to be attached to
them. Air cooled models have a single 3/4” FPT drain
tting in the back of the cabinet. Water cooled models
have the same tting plus an additional 1/2” FPT drain
tting in the back of the cabinet. Install new tubing
when replacing a prior ice machine, as the tubing will
have been sized for the old model and might not be
correct for this one.
Follow all applicable codes.

close and the water pump will stop. Water will ow
into the machine until the reservoir is full. The hot gas
valves and harvest assist devices will activate then
the compressor and water pump will start. If its an air
cooled model the fan motors will begin to turn. The
display will show a continuous F. Five seconds later
the hot gas valves will close and the harvest assist
device will return to its standby position. Warm air will
be discharged from air cooled models.
8. The display shows an H.
The hot gas valves open, the air cooled fan motors
shut o and the harvest assist mechanisms are
activated. The purge valve opens to drain some water,
when it does the inlet water valve opens to rell the
reservoir. After a few seconds the purge valve closes
but the inlet water valve continues to ll the reservoir.
Harvest continues until the ice is released as a unit
and forces the curtain to open. When both curtains reclose the controller returns the unit to a freeze cycle.
9. Check the ice harvested for proper bridge
thickness. The ice bridge is factory set at 3/16
inch. If needed, adjust bridge thickness. Do NOT
make it too thin.
10. Return the front panel to its normal position and
secure it to the machine.
11. Instruct the user in the operation of the machine
and its maintenance requirements.
12. Fill out and mail warranty registration form or

Adjustable ice level control
When this option is present there is an adjustment
post and an additional indicator light to the right
of the controller switches. 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
Note: Ice will build up in the bin or dispenser at an
angle, the distance set will be from the sensor to the
top of the ice. The sensor position is shown in the
cabinet layout diagrams.
Use of 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.
Rotate the adjustment post to the desired ice level.
The machine will ll up to that level and when it shuts
o the Bin Full indicator light will be On.

The cuber drops ice in large sections. That ice will
break up into random parts as it falls into the bin, but
some large sections may remain on top of the ice
in the bin. In a dispenser, this ice will break up into
mostly individual cubes as the dispense mechanism
moves the ice. The ice in the bin will normally slope
down from the right to the left.
Heat
When making ice, air-cooled models will discharge
hot air out the back of the cabinet.
Noise
The ice machine will make noise when it is in ice
making mode. The compressor, fan motor(s) if air
cooled, and water pump all produce some sound. It
is also normal to hear some cracking just before the
harvest cycle begins. In addition, during the harvest
cycle the harvest mechanism may click twice as it
pushes the ice out and returns to its normal position.
The ice harvests as a unit or slab, which makes some
noise when it impacts the bin or dispenser. These
noises are all normal for this machine.
The actual distance between the highest point of the
ice may be closer or further away than the distance
set, depending upon the angle of the ice.

Cleaning, Sanitation and Maintenance
This ice system requires three types of maintenance:
• Remove the build up of mineral scale from the ice machine’s water system and sensors.
• Sanitize the ice machine’s water system and the ice storage bin or dispenser.
• Clean or replace the air lter and clean the air cooled condenser (air cooled models only).
It is the User’s responsibility to keep the ice machine and ice storage bin in a sanitary condition. Without
human intervention, sanitation will not be maintained. Ice machines also require occasional cleaning of their
water systems with a specically designed chemical. This chemical dissolves mineral build up that forms during
the ice making process.
The ice machine’s water system should be cleaned and sanitized a minimum of twice per year. Sanitize the
ice storage bin as frequently as local health codes require, and every time the ice machine is cleaned and
sanitized.

oz of Nu-Calgon IMS Sanitizer with 1 gallon (128
oz) of 105-115 degree F. potable water.
8. Remove air lter(s)(if applicable), water level sensor
and housing, water distributor(s), curtain(s), ice
thickness sensor, and splash panel for additional
cleaning.
9. Soak and scrub each part (including the
evaporator cover!) using the previously prepared
solution of Scotsman Clear 1 scale remover and a
nylon brush, and then rinse with water. Save scale
remover solution.
10. Soak and scrub each part using the previously
prepared sanitizing solution. No rinse needed. Save
sanitizing solution.
11. Using a non-metallic scouring pad, scrub spillway
with sanitizer to remove any material buildup and
debris.
12. Reinstall ice thickness sensor, curtain(s), splash
panel, water distributor(s), and water level sensor in
their original positions. Be sure water level sensor
and ice thickness sensor are completely dry.

Water
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. There are
two ways water can contain impurities: 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.
Scotsman lters:
A triple head lter is recommended. Either the
Scotsman SSM3 taste and odor lter system, or the
ADS-AP3 AquaPatrol system.
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
Water Purge
Cube ice machines use more water than what ends
up in the bin as ice. While most water is used during
ice making, a portion is designed to be drained out
every cycle to reduce the amount of hard water scale
in the machine. That’s known as water purge, and an
eective purge can increase the time between needed
water system cleaning.
In addition, this product is designed to automatically
vary the amount of water purged based on the purity
of the water supplied to it. The water purge rate can
also be set manually. Adjustments of purge due to
local water conditions are not covered by warranty.
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, while
the ice making process itself will remove the chlorine
from the ice, resulting in no taste or odor impact.
Additionally, devices intended to enhance ice machine
sanitation, such as the Scotsman Aqua Bullet, can
be placed in the machine to keep it cleaner between
manual cleanings.

Remote Condenser Location
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.
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.

Use and Operation
Once started, the ice machine will automatically make
ice until the bin or dispenser is full of ice.
When ice level drops, the ice machine will resume
making ice. There are four indicator lights at the
front of the machine that provide information on the
condition of the machine.
Caution: Do not place anything on top of the ice
machine, including the ice scoop. Debris and moisture
from objects on top of the machine can work their way

button. The machine will shut o at the end of the next
cycle. To shut the machine o immediately, push and
hold the O button for 3 seconds.
To switch the machine ON, push and release the
On button. The machine will go through a start up
process and then resume ice making.
Control Options
There are two optional, eld installed controls that can
be added to this machine.
• Vari-Smart™ adjustable ice level control
• Smart-Board™ advanced control board and data
logger
Adjustable ice level control
Use of 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.
Rotate the adjustment post to the desired ice level.
The machine will ll up to that level and when it shuts
o the Bin Full indicator light will be On.
Ice
The cuber drops ice in large sections. That ice will
break up into random parts as it falls into the bin, but
some large sections may remain on top of the ice
in the bin. In a dispenser, this ice will break up into
mostly individual cubes as the dispense mechanism
moves the ice. The ice in the bin will normally slope
down from the right to the left.
When this option is present there is an adjustment
post and an additional indicator light to the right
of the controller switches. 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
Note: Ice will build up in the bin or dispenser at an
angle, the distance set will be from the sensor to the
top of the ice. The sensor position is shown in the
cabinet layout diagrams.
The actual distance between the highest point of the
ice may be closer or further away than the distance
set, depending upon the angle of the ice.
Heat
When making ice, air-cooled models will discharge
hot air out the back of the cabinet.
Noise
The ice machine will make noise when it is in ice
making mode. The compressor, fan motor(s) if air
cooled, and water pump all produce some sound. It
is also normal to hear some cracking just before the
harvest cycle begins. In addition, during the harvest
cycle the harvest mechanism may click twice as it
pushes the ice out and returns to its normal position.
The ice harvests as a unit or slab, which makes some
noise when it impacts the bin or dispenser. These
noises are all normal for this machine.
