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
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.
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.

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
Run = dd+rd+hd = Calculated Line Length
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.

Initial Start Up
1. Remove front and left side panels. Check machine
for any packing or wires rubbing moving parts.
Note location of control board in upper left corner
of the machine’s front.
2. Switch on the electrical power to the machine.
Observe that some of the control’s indicator lights
glow and its display shows O.
3. Wait 4 hours for the compressor’s crankcase
heater to warm up the oil in the compressor.
4. Open the water supply valve.
5. Turn the receiver’s outlet valve to the full open
position.
6. Push and release the ON button.
The indicator light will begin to blink F. The purge
valve will open and the water pump will start. The inlet
water valve will open to add water to the reservoir.
After a few seconds the purge valve will 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 and the liquid line
solenoid valve will open, then the compressor, remote
fan motor and water pump will start. The display will
show a continuous F. Five seconds later the hot gas
valves will close and the harvest assist devices will
return to their standby positions. Warm air will be
discharged from the condenser coil.
7. During the Freeze cycle move the curtain and
observe that the SW1 or SW2 light on the control
board blinks ON when the curtain moves away
from the evaporator and OFF when returned to its
normal position.
Note: Moving the curtain during the Freeze cycle has
no aect on unit operation.
8. Observe the Ready for Harvest indicator light. It
may blink early in the freeze cycle, that is normal.
The control will ignore that signal for the rst 6
minutes of freeze.
9. When the ice has frozen enough, the Ready for
Harvest indicator light will be on steady. After it’s
been on steady for a few seconds Harvest will
begin.
10. The display shows an H.
The hot gas valves open 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 from each evaporator and forces
each curtain to open.
11. When both curtains have opened and re-closed
the controller returns the unit to a freeze cycle.
12. 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.

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
into the cabinet and cause serious damage. Damage
caused by foreign material is not covered by warranty.

Indicator Lights & Their Meanings
If the Water light is on, the machine has sensed a
lack of water. Check the water supply to the machine.
The water may have been shut o or the water lter
cartridges need to be changed.
If the Clean light is on, the machine has determined
that it may need to be cleaned. Contact an authorized
Scotsman service agent and have the machine
cleaned, de-scaled and sanitized.
During normal operation, if the Clean light begins to
blink yellow, the machine in Preservation mode, which
initiates a timed freeze in response to short freeze
errors. Contact an authorized Scotsman service agent
to service the machine immediately. It is likely that
the machine needs to be cleaned (de-scaled and
sanitized), but may need additional service.
Note: A Component Indicator Light switches ON to
indicate that the component is operating.
Note: There are two Curtain Switch lights, SW1 and
SW2. A curtain switch light is ON when a curtain is
either open or not present.

Control Switches
The On and O switch buttons are front accessible.
To switch the machine OFF, push and release the O
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
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.
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.
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.

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 condenser
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.
Preparing to Clean:
1. Remove the front panel.
2. Remove the evaporator cover.
Scale Removal:
3. Push and release the Clean button. The yellow
Clean light will blink and the display will show C.
The machine will harvest any ice, drain the reservoir
and begin to rell it.
4. Observe code display, when it blinks the characters
“A d 1” immediately go to the next step.
5. Pour the below specied amount Scotsman Clear
1 ice machine scale remover into the reservoir. The
unit will circulate the scale remover, then drain and
ush it. This will take 35 minutes, then the machine
will stop and the display will show O.
Note: Using chemicals or dilution ratios other than
what is specied will damage the ice machine and
signicantly aect the performance and life of the ice
machine.
Clean internal parts:
6. Mix a
cleaning solution of 6oz of Scotsman Clear 1 scale
remover with 9 cups (72oz) of 105-115° F potable
water.
7. In a separate bucket, mix a sanitizing solution of 1.6
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.

What to do before calling for service
Reasons the machine might shut itself o:
• Lack of water.
• Freeze cycle takes too long.
• Harvest cycle takes too long.
• High discharge temperature.
• Controller self test failure.
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 25 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 water o to a water
cooled unit? If yes, after the water supply has
been restored the ice machine may need to be
manually reset.
4. Is the curtain open because some ice is stuck
under it? If so, remove the ice and the machine
should start in a few minutes.
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:
1. Push and hold the O button for 3 seconds or until
the machine stops.
2.
3.
4.
Note: Curtain can be removed & replaced anytime the
machine is in a standby mode or when it is in a freeze
cycle. However, removal of the curtain during freeze
will result in water owing into the bin. Removal of the
curtain during harvest terminates harvest at that point
and, if left o, will result in the machine shutting o.
