Placement
The location of the equipment should be selected
with care. Consideration should be given to allow
adequate space on the sides for air cooled models to
breathe.
Minimum clearances for air cooled models:
• 15 cm at each side
• 5 cm above, 25 cm more to allow auger removal
when ceiling is xed.
• None at the back.
Air cooled models ow air left to right. More space
than the minimum at the sides will maximize
performance.
The power outlet should be located within the length
of the supplied power cord. If placed on a counter,
the counter must be strong enough to support the
weight of the unit. Space above the cabinet should be
allowed for service and maintenance. If legs will be
used, allow space for the total cabinet height.
Air cooled models in a small room will require
ventilation to exhaust the heat they produce. They
also produce some added noise from the fan.
Noise sensitive areas should consider water cooled
equipment or the machine located where the noise
from ice making is not objectionable.
Nearby infrared emitters or a window that allows
sunlight to shine on a dispensing sensor may cause
the unit to dispense ice or water without a container to
trigger it.
Cafeteria applications.
The unit can be placed in a cafeteria line for ice and
water. As some users sometimes dispense too much
ice, high volume use may require the drip tray to be
occasionally cleared of spilled ice.
Unpack
1. Separate the carton from the shipping pallet.
2. Remove any strapping holding the cabinet to the
pallet.
3. Inspect for hidden shipping damage. If any is
found, retain carton and notify carrier for potential
claim. Shipping damage is not covered by
warranty.
4. Remove bolts holding machine to pallet. Use
caution to not tip unit too far when removing bolts.
5. Remove plastic covering the drip tray.
6. Remove the protective plastic covering the panels.
The longer it is left on the panel, the harder it will
be to remove it.
7. Place unit on machine stand or on counter. If on
machine stand secure the cabinet to the machine
stand with the required fasteners.

Installation
Installation should be done by an experienced ice
machine installer. To locate one, call the number on
the back of this manual or go to Scotsman’s website
www.scotsman-ice.com to identify a local distributor or
service company.
The machine will require power, water and drain.
Locate the water supply tting on the lower back of
the cabinet and obtain the correct tting to connect
the water supply.
Plumbing Fittings:
• The water supply connection is at the back panel,
50 Hz models have a single 3/4 gas BNF inlet water
connection and a connecting hose is supplied.
Note: New connecting hose is supplied do not re-
use old hose set
All models:
Connect the potable water supply to the inlet
at the bottom back of the unit. 3/8” OD tubing
recommended. Water lters may be used but are not
required. Note that activated carbon or charcoal water
lters are used for taste and odor problems but also
take out any chlorine that the local water agency may
have added for purication. That can require more
frequent sanitization of the equipment.
Connect drain tubing to the central drain tting at the
back of the cabinet. Use 3/4 inch rigid tubing, use
material to meet local codes. The drain basin in the
machine will act as an internal vent, no additional
vent should be required unless there is a very long
horizontal run. Drain tubing must pitch down 1/4 inch
per foot to the building drain. Insulation of drain tubing
is recommended for most environments.
Electrical Supply
Power Cords:
50 Hz models are equipped with a cord without plug.
When adding a plug, connect the plug to the power
cord in compliance with the local electrical codes.
Select an appropriately certied plug based on the
country of use, current rating of the appliance and
suitability for use with 1.5 mm 2 x 3 conductor type
H05VV-F cord
Note: In case the power cord is damaged, it
must be replaced by a like cord. Replacement
cords are available from the manufacturer’s local
representative. Replacement should only be done
by a qualied technician to prevent possible risks.
The disconnection from the supply mains has
a contact separation in all poles that provides
full disconnection under overvoltage category III
conditions. The devices for disconnection must be
incorporated in the power supply line in accordance
with wiring rules.
Position the unit in its nal location.
Level the unit front to back and left to right.
Seal to the countertop as required per local codes.

Initial Start Up
Final check list:
1. Is the icemaker-dispenser installed indoors, in a
location where the air and water temperatures
are controlled, and where they do not go beyond
design limitations?
2. Is there an electrical disconnect (switch or
plug as required) within sight of the installed
machine? Is the machine on a separate circuit?
Has the voltage been checked and compared to
nameplate requirements?
3. Have all of the plumbing connections been made
and checked for leaks?
4. Has the machine been leveled?
5. Is there a minimum of 15 cm of clearance at the
left and right sides of an air cooled machine?
6. Is there clearance at the top and back of the
machine for service and utility connections?
7. Is there a water shut off valve installed near the
machine?
Start Up
1. Remove upper front panel
2. Open the water hand valve, observe that water
enters the water reservoir, lls and then shuts off.
Check for leaks. Repair any leaks before going
any further.
3. Switch electrical supply on. Lights on controller
will ash and then the power light will remain on.
The code display will show O.
4. Push and release the On/Off button. The machine
will start the ice making process. The code display
will show F. Air cooled models will discharge warm
air out the right side.
5. In minutes ice will begin to fall into the dispensing
bin. Check ice dispensing by holding a container
in front of the Touch Free ice sensor (just below
the ice delivery spout). Ice should ow from the
spout when a container is present, and stop
dispensing when the container is removed.
6. Check water dispensing by holding a container in
front of the Touch Free water sensor. Water will
ow when a container is present and stop when it
is removed.
7. Push the On/Off button to switch the machine off.
8. Unplug or disconnect electrical power.
9. Remove the top panel and the top of the ice
storage bin. Scoop out any ice in the bin and
sanitize the interior of the ice storage bin by
wiping it with a locally approved sanitizer.
10. Reconnect electrical power.
11. Push the On/off button to switch the machine on.
12. Replace all covers and panels.
13. Give the owner/user the user manual, instruct
him/her in the operation and maintenance
requirements of the unit. Make sure they know
who to call for service.

Operation: Ice and Water Vending
During ice making soft ice is compressed thru a die
and then broken off into irregular lengths. It will not be
clear and, because of melting, when dispensed it will
not be uniform in size or shape.
Dispensing takes place when the Touch Free sensor’s
infrared beam bounces back to the sensor from a
container placed directly in front of it.
If the container is in front of the Touch Free sensor
on the left side, the ice dispensing rotor will rotate
and sweep ice over the ice dispensing chute. Ice will
continue to discharge out this chute as long as the
rotor is turning. It stops when the rotor stops.
If the user does not remove the container, ice will be
dispensed for 24 seconds and then stop.
If the container is in front of the Touch Free sensor on
the right side, the inlet water valve will open and water
will ow into the container.
If the user does not remove the container water will be
dispensed for 20 seconds and then stop.
Note: Water may dispense cloudy and then clear up in
the glass. That is normal due to air in the water and is
not an indicator of any malfunction.
Other notes:
• An occasional drip may be seen from the ice
dispense chute. This is normal and is from ice melting
inside the chute. A continuous stream of water from
the ice chute indicates a restricted bin drain.
• Clear containers (glass or plastic) may not always
activate the dispense sensors. Retry with an opaque
container.
• The drip tray is not a sink and cannot tolerate
garbage. Coffee and soda should not be discarded
into it. Debris like stirring straws that are discarded
into the drip tray will likely cause a drain back up
and need to be removed as soon as they are found.
To minimize the risk of a clogged drain do not allow
anything other than water to go down the drain.
• Both dispensing and ice making are disabled
when the unit is switched off at the controller.
Splash panel wipe-off. Wiping the splash panel could
result in unintended dispensing. To avoid that, a
disable button has been provided. It is recessed into
the bottom of the chute panel. Push and release it to
disable dispensing for 60 seconds.
Noise
This is a commercial ice machine. It contains a
powerful compressor, heavy duty gear reducer and, if
air cooled, a fan that moves a lot of air. It will produce
some noise when it is making ice. Every effort was
made during its design to minimize the sound level

Controller
All models use the same control system.
The electronic controller operates the compressor
(with fan motor), auger drive motor, dispense drive
motor and inlet water solenoid valve. It monitors:
• Reservoir water availability
• Storage bin ice level
• Call for ice dispense
• Call for water dispense
• Refrigeration pressure
• Dispense enable / disable
• Auger motor speed
• Auger motor rotation
• Any installed control options
Many of these are used to insure that the machine
does not damage itself during use. For example, it is
critical that it not attempt to make ice without water, so
if the water sensor is dry, the machine will not make
ice.
Switches - there are four switches:
• Dispense water - to test water dispensing
• Dispense ice - to test ice dispensing
• On/Off - to switch the machine on or off. Holding it
in to shut off will stop ice making immediately.
• Clean - to engage the clean mode
Indicators - there are nine LEDs:
• Power - Glows when controller has power
• Status - Glows when in ice making mode
• Time to Clean - Glows when it is time to clean the
machine
• Water Dispense Sensed - glows when the water
dispense sensor has been triggered*
• Ice Dispensed Sensed - glows when the ice
dispense sensor has been triggered*
• Water Dispense - glows when the inlet water
solenoid valve has been powered*
• Ice Dispense - glows when the ice dispense
motor has been powered*
• Auger - glows when the auger motor is on
• Compressor - glows when the compressor is on
* If blinking the water or ice dispensing time limit has
been met.
There is also a code display, the codes are:
O- - - for off
F- - - for ice making
b- - - for bin full
E- - - for controller error
C- - - for clean mode
d- - - for test mode
1- - - for auger rotation direction wrong
2- - - for auger speed too slow
3- - - for no water sensed
4- - - for high refrigerant pressure
If a number code is triggered, the controller will stop
ice making. A blinking code means it is a temporary
condition. Example: A blinking Foccurs during the
ice making restart process; it stops blinking when the
compressor starts.
The controller will automatically restart from a water
interruption or power interruption or when a refrigerant
pressure switch has automatically reset.
To reset the control when it has been manually locked
out, Push and release the On/Off button to shut it Off
and then Push and release it again to switch it On.
Note: The compressor will not restart for 2 minutes
from the time it was shut off.

Air lter
The air lter on the left side of the cabinet will capture
signicant dust and lint during operation. As the dirt
builds up it begins to restrict air ow and causes the
refrigeration system to work longer to make ice. Clean
the air lter regularly.
To remove, pull it forward from the louvers. Do not
leave it out for extended periods of time.
To clean, wash it at a utility sink. Return it to the unit
when clean.
Condenser.
The condenser ns may need cleaning too. Remove
the left side air grill and brush any lint and dirt off the
surface of the condenser. Vacuum any remaining
dirt. Do not damage the ns of the condenser during
cleaning.

Other Maintenance
Note: Cleaning and maintenance must not be done by
children without supervision.
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.
Sanitize the ice storage bin as frequently as local
health codes require, and every time the ice machine
is cleaned and sanitized.
The ice machine’s water system should be cleaned
and sanitized a minimum of twice per year. This is
critical to the proper operation of the ice machine.
Contact your local authorized service agent for water
system cleaning.
The auger in the ice making system is centered by
bearings at the top and bottom. It is also sealed from
leaking by a water seal at the bottom.
The bearings are permanently lubricated and need
no maintenance. The can be visually checked for
obvious wear or damage but there is no need to add
lubrication.
Auger motor bearings and the gear reducer are also
permanently lubricated and need no maintenance.
The bottom of the ice making system should be
checked for water leaks. Water draining from
the bottom is an indication of a water seal leak.
Immediate repair is required when a water seal leak is
discovered.
Caution: Moving parts hazard. Do not touch the
rotating shaft at any time.

Ice level control sensing full bin falsely. Controller
shows b. Clean ice level control sensors.
Dispense motor not turning Remove upper front panel, check controller indicator
lights. Hold container in front of sensor, does the
Ice Dispense Sensed light glow? If no, sensor is
not detecting the container. If yes, does the Ice
Dispense light glow? If yes, push Dispense Ice
button. Does the motor activate? If yes, go to next
row. If no, check for voltage at motor. If no voltage,
replace controller. If voltage at motor, replace
motor.
Dispense motor working,
but ice in bin not moving
Agitator or rotor not turning, remove all ice and
inspect for damage to agitator and rotor.
No water is dispensed No water to unit. Restore water.
Water valve not opening Remove upper front panel, check controller indicator
lights. Hold container in front of sensor, does the
Water Dispense Sensed light glow? If no, sensor is
not detecting the container. If yes, does the Water
Dispense light glow? If yes, push Dispense Water
button. Does the water valve activate? If no, check
for voltage at valve. If no voltage, replace controller.
If voltage at valve, replace valve.
Water drips from spout May be normal A few drops per minute is normal.
Bin drain may be plugged. Check bin drain tube at basin.
Dispensed water is
cloudy, but clears up in a
few minutes
Air in the water This is normal and can vary depending upon how
much air is in the water. May be improved by
lowering water pressure to the unit.
Water leak near front Drip tray not in position Conrm drip tray is pushed all the way back and
touching the base.
Water lling drip tray Main drain plugged Remove splash panel and inspect basin for standing
water. Clear drain to and from the basin. If plugged
with mold/slime it would be recommended to use a
sanitizing solution to ush the drain line. To minimize
the risk of a clogged drain do not allow anything
other than water to go down the drain..
