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 filtered out. In solution or
dissolved solids cannot be filtered, they must be diluted or treated. Water filters are
recommended to remove suspended solids. Some filters 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 filters remove chlorine from the water supply to the machine which
contributes to this situation. Testing has shown that using a filter 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 effective
purge can increase the time between needed water system cleaning.
In addition, this product has the capability to automatically vary the amount of water purgeed
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.

General Installation - Air or Water Cooled
Location Limitations:
The product is designed to be installed indoors, in a controlled environment. Air cooled models
discharge very warm air into the room out the back. Space must be allowed at the left side and
back for air intake and discharge. Water cooled models discharge warm water into the
building’s drain. Space needs to be provided on both sides and above for service access.
Space Limitations
Note: Although the machine will function, ice capacity of air cooled machines will be significantly reduced
with minimal clearance at the sides, back and top. Some space is recommended for service and
maintenance purposes on all models.
6" of space at the sides and back are required for adequate operation. To get the most
capacity, locate the machine away from heat producing appliances and heating ducts.
22 and 30 inch wide models: Airflow is in the left side, out the back (as viewed from the front).
48 inch wide models: Air flow is in the front and left side and out the back.

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.

General Installation - Air or Water Cooled
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; a 3/8”
FPT to 3/8” male flare adapter is supplied with the machine and can be used if desired.
Water cooled models have the same inlet fitting plus an additional 3/8” FPT condenser inlet
water connection.
Water Filters
If connecting to water filtration, filter only the water to the reservoir, not to the condenser.
Install a new cartridge if the filters were used with a prior machine.
All models require drain tubing to be attached to them. Air cooled models have a single ¾”
FPT drain fitting in the back of the cabinet. Water cooled models have the same fitting plus an
additional ½” FPT drain fitting 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.
Note: This NSF listed model has a 1" anti-back flow air gap between the water inlet tube end and the
highest possible reservoir water level, no back flow device is required for the potable water inlet.
Drain Tubing:
Use rigid drain tubes and route them separately – do not Tee into the bin’s drain and, if water
cooled, do not 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..
Horizontal runs of drain tubing need a ¼” fall per foot of run for proper draining.
Follow all applicable codes.

Remote Condenser Location
Use the following for planning the placement of the condenser relative to the ice machine - see
illustration on the following page.
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
Configurations 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.
Operating a machine with an unacceptable configuration is misuse and will void the
warranty.

Precharged Line Routing
Do not connect the precharged tubing until all routing and forming of the tubing is complete.
See the Coupling Instructions for final 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, the end without access
valves goes to the ice maker.
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 roofing contractor cut a minimum hole for the refrigerant lines of 1 3/4”. 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. 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.
Note brazing requires a nitrogen purge.
If the excess tubing is to be coiled, spiral it horizontally to avoid excess trapping in the lines.
5. Have the roofing contractor seal the holes in the roof per local codes
September 2006 Page 15

Coupling Instructions
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 Certified 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.
3. Position the fittings on the correct connections on the condenser and ice machine.
• The 1/2" discharge line (schrader valve end) goes to the remote condenser fitting marked
“discharge line”.
• The 3/8" liquid line (schrader valve end) goes to the remote condenser fitting marked
“liquid line”.
• The 1/2" discharge line goes to the ice maker fitting marked “discharge line”.
• The 3/8" liquid line goes to the ice maker fitting marked “liquid line”.
Final Connections:
4a. Begin by tightening the couplings together by hand until it is certain that the threads are
properly engaged.
4b. Then using two wrenches tighten the coupling until it bottoms out or a definite 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.
4c. Continue tightening the swivel nut until it bottoms out or a very definite increase in
resistance is felt (no threads should be showing).
5. Use a marker or pen to 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.
6. After all connections have been made, and after the receiver valve has been opened (open
at Initial Start Up), check the couplings for leaks.
September 2006 Page 16
Pre-Charged Tubing Coupling Connections
Inspect couplings, wipe clean and lubricate
both parts with polyolester refrigerant oil.
Hand tighten to be sure threads are properly
engaged.
Use two wrenches and continue tightening the
couplings. As the diaphragms being to pierce,
the couplings will be harder to turn. Be sure
only the swivel nut is rotated.
Continue tightening until the swivel nut feels
like it is tight, then go to the next step. No
threads will be seen when the couplings are
tight.
After the swivel nut feels like it is tight, mark
the nut and the panel. Then tighten one
quarter turn more. That ensures that there is
a brass-to-brass joint inside the coupling.

How It Works - Air Cooled
Freeze Cycle. At start up the controller drains and refills the reservoir. The reservoir refills
when the mid length water level sensor probe is uncovered and continues to fill until the top
probe is in contact with water. When the reservoir has filled, the compressor and water pump
start. After the discharge pressure has increased past the cut in point of the fan pressure
control, the fan motor(s) will begin to operate and warm air will be discharged out the back of
the cabinet. The fan motor will switch on and off as the discharge pressure rises and falls.
Water flows over the evaporator as the refrigeration system begins to remove heat. When the
water temperature falls to a preset point, as measured by the water temperature sensor, the
controller shuts off the water pump for 30 seconds. The freeze cycle resumes when the pump
restarts and ice begins to form on the evaporator. As it forms, the water flowing over the ice
moves closer and closer to the metal tip of the ice thickness sensor. When it comes into
contact with the sensor for a few continuous seconds, that signals the controller that the freeze
cycle is complete.
The controller may shut the air cooled fan motor off for a variable period of time to build up
heat for harvest. This is dependant upon the temperature of the discharge line sensor.
Harvest Cycle. When the harvest cycle begins, the controller shuts off the fan motor, switches
on the hot gas valve, and through a parallel circuit, the harvest assist solenoid. After a few
seconds the purge valve opens and water is drained from the reservoir. Based on either the
automatic purge or manual purge setting, the pump and purge valve will be switched off at a
time determined to have drained enough water for that setting. The inlet water valve will open
to fill the reservoir anytime the mid length probe is uncovered, which occurs during the
reservoir drain cycle. Harvest continues as the hot discharge gas flows into the evaporator
serpentine, heating up the evaporator. At the same time the harvest assist solenoid is pushing
against the back of the ice slab. When the ice releases from the evaporator, it harvests as a
unit, and the harvest assist probe provides some additional force to push it off. When the ice
falls off it will force the curtain(s) open. An open curtain during the harvest cycle signals the
controller that the evaporator has released its ice. If this is a single evaporator machine the
controller will terminate harvest. If it is a two evaporator machine, the controller will continue
harvest until both curtains have opened. If one curtain remains open, the controller will shut the
machine down on bin full. Anytime harvest is complete the hot gas valve and harvest assist
solenoid are shut off. The harvest assist solenoid pin returns to its normal position by spring
pressure.
If the curtain(s) re-close after harvest, the freeze cycle will restart.

Freeze Cycle. At start up the controller drains and refills the reservoir. The reservoir refills
when the mid length water level sensor probe is uncovered and continues to fill until the top
probe is in contact with water. When the reservoir has filled, the compressor and water pump
start. After the discharge pressure has increased past the set point of the water regulating
valve, the water regulating valve will open and warm water will be discharged out the
condenser drain. The water regulating valve will modulate to maintain a relatively constant
discharge pressure. Water flows over the evaporator as the refrigeration system begins to
remove heat. When the water temperature falls to a preset point, as measured by the water
temperature sensor, the controller shuts off the water pump for 30 seconds. The freeze cycle
resumes when the pump restarts and ice begins to form on the evaporator. As it forms, the
water flowing over the ice moves closer and closer to the metal tip of the ice thickness sensor.
When it comes into contact with the sensor for a few continuous seconds, that signals the

Harvest Cycle. When the harvest cycle begins, the controller switches on the hot gas valve,
and through a parallel circuit, the harvest assist solenoid. After a few seconds the purge valve
opens and water is drained from the reservoir. Based on either the automatic purge or manual
purge setting, the pump and purge valve will be switched off at a time determined to have
drained enough water for that setting. The inlet water valve will open to fill the reservoir
anytime the mid length probe is uncovered, which occurs during the reservoir drain cycle.

curtain(s) open. An open curtain during the harvest cycle signals the controller that the
evaporator has released its ice. If this is a single evaporator machine the controller will
terminate harvest. If it is a two evaporator machine, the controller will continue harvest until
both curtains have opened. If a curtain remains open, the controller will shut the machine down
on bin full. Anytime harvest is complete the hot gas valve and harvest assist solenoid are shut
off. The harvest assist solenoid pin returns to its normal position by spring pressure.
If the curtain(s) re-close after harvest, the freeze cycle will restart.

Freeze Cycle. At start up the controller drains and refills the reservoir. The reservoir refills
when the mid length water level sensor probe is uncovered and continues to fill until the top
probe is in contact with water. When the reservoir has filled, the liquid line valve, compressor
and water pump are switched on. After the discharge pressure has increased past the set point
of the headmaster in the condenser, the headmaster will direct refrigerant gas into the
condenser and warm air will be discharged out of the condenser. The headmaster will
modulate to maintain a minimum discharge pressure. Water flows over the evaporator as the
refrigeration system begins to remove heat. When the water temperature falls to a preset point,
as measured by the water temperature sensor, the controller shuts off the water pump for 30
seconds. The freeze cycle resumes when the pump restarts and ice begins to form on the
evaporator. As it forms, the water flowing over the ice moves closer and closer to the metal tip

opens and water is drained from the reservoir. Based on either the automatic purge or manual
purge setting, the pump and purge valve will be switched off at a time determined to have
drained enough water for that setting. The inlet water valve will open to fill the reservoir
anytime the mid length probe is uncovered, which occurs during the reservoir drain cycle.
Harvest continues as the hot discharge gas flows into the evaporator serpentine, heating up
the evaporator. At the same time the harvest assist solenoid is pushing against the back of the
ice slab. When the ice releases from the evaporator, it harvests as a unit, and the harvest
assist probe provides some additional force to push it off. When the ice falls off it will force the
curtain(s) open. An open curtain during the harvest cycle signals the controller that the
evaporator has released its ice. If this is a single evaporator machine the controller will
terminate harvest. If it is a two evaporator machine, the controller will continue harvest until
both curtains have opened. If a curtain remains open, the controller will shut the machine
down. Anytime harvest is complete the hot gas valve and harvest assist solenoid are shut off.
The harvest assist solenoid pin returns to its normal position by spring pressure.
If the curtain(s) re-close after harvest, the freeze cycle will restart.
Shut down occurs when a curtain remains open after a harvest cycle. The controller will switch
off the liquid line solenoid valve and operate the compressor for 30 seconds, then shut it off.

If the self check passes, the controller will display a 0, the curtain light(s) will be ON and the
Power and Sump Empty lights will be ON.
Pushing and releasing the On button will start the ice making process.
The display will begin to blink F. The component indicator lights will switch on and off to match the
following process:
The purge valve opens and the water pump starts to empty the reservoir. This is done to
discharge any excess water from ice melting into the reservoir.
The hot gas valve and the harvest assist solenoid are energized.
The inlet water valve will open to fill the reservoir. The water valve can open any time the water
level is low.
After a few seconds the purge valve closes and the pump shuts off.
When the reservoir is full the inlet water valve stops and the compressor switches on. Five
seconds after the compressor starts the hot gas valve and the harvest assist solenoid are
de-energized.
Light Information: The display shows a non-blinking F. The Power and Status Lights will be Green. The
compressor, fan motor, water pump, sump full and one or two curtain switch lights will be ON.
The air cooled model's fan motor will start to turn when the discharge pressure has built up to
the fan pressure control's cut in point. This is about 15 seconds after the compressor starts.
The Freeze cycle continues. The compressor, water pump, fan motor and curtain indicator
lights will be ON. When the reservoir water temperature falls to a certain preset point, the
water pump will shut off for 30 seconds. This is the anti-slush period. At this time the controller
checks the conductivity of the water in the reservoir for the auto-purge feature. After the water
pump restarts the Sump Full light will go out and neither sump lights will be on for the rest of
the freeze cycle.
When the ice has built up enough so that the water flowing over the evaporator comes into
continuous contact with the ice level sensor, the Ready to Harvest light will begin to blink on
and off. When it has been On continuously for 5 seconds, the controller will switch the machine
into a Harvest cycle.

Harvest continues until the ice slab is ejected from the evaporator and falls, opening the
curtain. When the curtain opens, the magnetic reed curtain switch opens, breaking the circuit
to the controller. If the curtain re-closes within 30 seconds, the controller switches the machine
back into another freeze cycle. If the curtain switch remains open, the controller shuts the
machine down and puts it into a standby position.

Control Safeties
Max freeze time – 45 minutes
When exceeded, the controller will attempt another freeze cycle. If the next cycle's freeze time
is less than maximum, the control will continue normal ice making. If the next freeze cycle was
too long, the control will again attempt another freeze cycle. If the freeze cycle is too long three
consecutive cycles, the controller will shut the unit off and it must be manually reset.
Min freeze time – 6 minutes
If the controller switches the machine into harvest within 20 seconds of the minimum freeze
time, the controller will harvest for a preset time and does not stop if the curtain switch opens.
If this occurs again in the next three cycles, the machine will shut down and must be manually
reset.
Max harvest time – 3.5 minutes
If the harvest cycle has continued for 3.5 minutes without the curtain opening, the controller will
shut the machine off for 50 minutes and then restart. If there is another the machine will shut
the machine off for another 50 minutes and then restart. If it fails a third consecutive time the
controller will shut the machine down and must be manually reset.

Test Procedures - Sensors
All electrical components in this ice machine can be diagnosed with a volt-ohmmeter.
Curtain Switch:
1. Test using the controller’s indicator lights. Observe SW1 and SW2. Open and close the
curtain in question. When the curtain is opened, the SW light will be ON. When the curtain gets
to within a half inch of closing (at the switch) the SW light will go OUT.
2. Test with an ohmmeter. Disconnect electrical power. Open the control box cover. Unplug the
curtain switch lead from the controller. Connect an ohmmeter to the leads of the switch. Open
and close the curtain. When the curtain is closed, the switch is closed and there will be
continuity. When the curtain is open, the switch is open and the circuit will be open.
3. Test the controller’s curtain switch circuit by jumping the connectors on J1 or J2 together.
Reconnect electrical power. When jumped, the matching SW light will go out. When unplugged
or open, the SW light will be ON.

Ice Thickness Sensor
1. Test using the controller’s indicator light. Observe the Ready To Harvest light. Shut the
machine off. Use a wire to connect the metal part of the Ice Thickness sensor to the
evaporator or simply remove the Ice Thickness Sensor and touch its metal surface to the metal
control box wall. The Ready for Harvest light should go ON.
2. Test with an Ohmmeter. Disconnect electrical power. Open the control box cover. Unplug
the ice thickness sensor lead from the controller. Connect an ohmmeter lead to the ice
thickness sensor lead, touch the other ohmmeter lead to the ice machine chassis. There must
be an open circuit. If there is continuity, the sensor must be replaced. If there is no continuity,
touch the ohmmeter lead to the metal part of the ice thickness sensor. There should be
continuity. If open, check the ice thickness sensor for scale build up. Clean and recheck. If still
open, replace the ice thickness sensor.
3. Test the controller’s ice thickness sensor circuit by connecting a wire from J10 to ground.
Reconnect electrical power. The Ready for Harvest light should go ON.

Water Level Sensor
1. Test using the controller’s indicator lights (sump empty and sump full). Unit must be
powered up and there must be water in the sump. Add some manually if needed. Locate water
level sensor. Release from sump cover and slowly lift up until the mid-length probe is out of the
water. The sump empty light should come on, and if the unit is on the inlet water solenoid valve
will open to fill the reservoir. Return the water level sensor to its normal position. If the unit is
on and calling for ice the water will fill until the top probe is in contact with it, at that time the
sump full light will switch ON.
2. Test with an ohmmeter. Disconnect electrical power. Open the control box cover. Unplug the
connector at J9. Locate water level sensor and remove it from the sump cover. Test 1: Place
one lead of the ohmmeter on the longest probe and the other on the controller end of the red
wire, there should be continuity. Test 2: Place one lead on the controller end of the white wire
and the other on the mid-length probe, there should be continuity. Test 3: Place on lead on the
controller end of the black wire and the other on the shortest probe, there should be continuity.
If not, clean the probes and recheck.
3. Test the controller’s water level sensor circuit. Reconnect electrical power. Unplug harness
from water level sensor, the sump empty
light should be ON. Jump harness wires
white and black. The sump full light should
be ON. Jump harness wires white and red,
the sump full and sump empty lights will be
OFF. Check harness wire by wire for
continuity if there is no reaction from the
controller during this test.

Temperature Sensors
1. Check controller. If the sensor calibration is completely out of range, the code display will
read either 5 or 7.
2. Check with an ohmmeter. Open control box cover, unplug sensor from J6. Water
temperature probe: Measure the temperature of the water. Push and release the clean button.
Wait one minute. Measure the resistance of the water probe (two leads next to the open
socket) and compare to the resistance in the chart for that temperature. Any reading within
1000 ohms is acceptable. Discharge sensor: Measure the temperature of the discharge line as
close to the sensor as possible. Measure the resistance of the discharge temperature sensor
(two leads farthest away from the open socket on the harness connector) and compare to the
resistance in the chart for that temperature. Any reading within 1000 ohms is acceptable.
3. Alternate procedure: Remove both water and discharge sensors from their places on the ice
machine. Put both into a container of ice water. Put a thermometer in the water. When the
thermometer is at 32 degrees F., check the resistance of each sensor. The resistance should
be within 1000 ohms of 32649.

Compressor
Failure to start.
Single phase models. All have resistance start, capacitor run type motors. Check voltage to
compressor at the contactor. Compare the idle voltage (compressor off) to the active voltage
(compressor starting). The supply voltage must not be less than the lowest rated voltage for
the ice machine. If the voltage is correct, proceed to the next step.
Check starting components. Most models use a PTCR to cut power to the start winding after
the compressor has started. Check the PTCR for resistance. The resistance check must be
when the PTCR is at room temperature – any temperature between 50 and 100.
At that temperature resistance should be very low between 25 and 50 ohms. Also check
resistance to ground, it should be infinite. If the PTCR is good, check the compressor windings.
Measure resistance from Common to ground. It should be infinite. Measure resistance from
Common to Run – compare to the chart. Measure resistance from Common to Start – compare
to the chart.
Compressor check for high amp draw. Measure amp draw of starting circuit. If it does not drop
off immediately after start up, the PTCR should be replaced. It is not practical to check a PTCR
for resistance at high temperatures as the resistance drops very fast as the PTCR’s
temperature falls. If the compressor is drawing excessive amps but is operating, the run
capacitor may be open. Disconnect electrical power, discharge the capacitor and measure its
resistance. If open, replace it. If shorted to ground, replace it.
Any time the compressor is replaced, the PTCR and run capacitor should also be replaced, or
if the model was equipped with a potential relay, start capacitor and run capacitor, those
should be replaced with the compressor. Most Scotsman service compressors include those
parts.
Some systems use a potential start relay and start capacitor in place of the PTCR.
Potential relay. If the compressor will not start, check the amp draw of the starting circuit. If
very low, the potential relay contacts or start capacitor may be open. Measure the resistance of
the potential relay contacts and the start capacitor. If either is open it should be replaced. If the
compressor starts but draws very high amps from the starting circuit, the potential relay may
not switch off. In that case the relay should be replaced.

Test Procedures - Loads
Fan motor
1. Test using the controller’s indicator lights.
Note: Fan pressure control connection must be jumped to perform this test.
Put the controller into test mode (depress Off for 3 seconds then depress Clean for 3
seconds). At the end of the test cycle, the fan motor will be powered and the Condenser Fan
motor indicator light will be on. The fan motor should start and run at that time. If it does not,
repeat the test but check the voltage to the fan motor, it must receive full voltage at the fan
motor lead connection at the end of the test. If there is voltage and the motor does not operate,
replace the motor. If there is no voltage, check the controller high voltage harness connection.
The fan motor lead is the top wire. Check voltage from it to ground, at the end of the test, when
the fan motor indicator light is On, there must be voltage from this pin to ground. Note: high
voltage power is supplied to the bottom pin from the contactor line. Refer to the machine wiring
diagram as needed.
2. Test using an ohmmeter. Disconnect electrical power. Unplug fan motor from harness.
Measure fan motor winding resistance. If open, replace the fan motor.
This light is ON when the
fan motor should be in
operation.

Test Procedures - Loads
Water Pump
1. Test using the controller’s indicator lights. Check the indicator light during the freeze cycle.
The light will be On for all but the 30 second anti-slush period, so observe the light for one
minute. When it is On, check the water pump, it should be operating. If not, check voltage to
the pump. If low check the voltage from the controller to ground. The water pump pin is
number 6. If there is voltage at that pin to ground, but very low voltage at the pump motor,
there must be a broken wire in the harness. If the voltage is low at pin 6, the controller should
be replaced.
2. Test using an ohmmeter. Disconnect electrical power. Unplug the water pump motor leads
from the harness. Measure the resistance of the motor windings. If open, replace the pump.
Measure resistance to ground. If there is any, replace the pump.
Water pump light is ON when
pump is in operation.

Test Procedures - Loads
Purge valve
1. Test using the controller’s indicator lights. Shut unit off by holding the Off button for 3
seconds. Wait four minutes. Push and release the On button, observe the Purge Valve
indicator light. As the unit drains the reservoir, the purge valve will be powered. When it gets
power, the indicator light will be ON. If the purge valve does not open to drain the reservoir
when its indicator light is on, do a voltage check. Shut the unit down by holding the Off button
in for 3 seconds. Unplug the harness connection from the purge valve. Wait four minutes. Push
and release the On button to restart the machine. As the unit drains the reservoir, the purge
valve connection should receive full voltage. If it does, the purge valve should be replaced. If
there is no voltage, check voltage from the controller to ground. The purge valve pin is 3 (dump
valve on wiring diagram). If there is voltage from that pin to ground, but low voltage at the valve
harness connection, the harness has a broken wire or poor connection and must be replaced.
If the voltage to ground is low, the controller should be replaced.
Note: The coil of this valve is internally rectified, and will normally show infinite resistance when tested
with an ohmmeter.
This light will be ON
when the Purge Valve is
in operation.

Test Procedures - Loads
Compressor contactor
1. Test using the controller’s indicator lights. When the unit is in ice making mode the
compressor contactor will have power. Check the Compressor indicator light, when it is on the
compressor contactor will have pulled in. If it is not, do a voltage check. Place voltmeter leads
on the coil of the contactor. There should be full voltage . If there is full voltage present and the
contactor has not pulled in, replace the contactor. If there is no voltage check if the high
pressure cut out is open. If the high pressure cut out is closed, check for voltage from the
controller to ground. The contactor pin is 4. Check from 4 to ground when the compressor
indicator light is on. There should be voltage. If not, replace the controller. If there is voltage at
the controller but not at the contactor coil, the harness wires or connectors are damaged and
must be replaced.
2. Test using an ohmmeter. Test the coil of the contactor for continuity or shorts to ground.
Replace if open or shorted.
3. Check connections and contacts. Be sure connections are tight and that the contacts are not
burnt. Replace any contactor with burnt contacts.
This light will be ON when
the compressor contactor is
powered.

Test Procedures - Loads
Pressure switches
There are two pressure switches: Fan and High Pressure cut out.
Fan. The fan pressure switch will open to shut the fan motor off at a certain pressure and
re-close at a preset higher pressure.
High pressure cut out. The high pressure cut out switch will open at a preset pressure, shutting
off power to the compressor contactor. After the pressure has fallen to another preset level, the
switch will re-close and the contactor coil will be engergized.
To Test Fan Pressure Switch:
A. Attach refrigeration gauge set to high side port.
B. Unplug both wires from fan pressure control. Be SURE the wire's terminals are wrapped
in electrical tape to prevent short circuits to ground during the test.
C. Connect ohmmeter to terminals of fan pressure control..
D. Switch ice machine on, observe pressure that the pressure control closes at, compare to
spec. Switch unit off, allow system to equalize, observe pressure the pressure control opens
at, compare to spec.
To Test High Pressure Switch:
A. Attach refrigeration gauge set to high side port.
B. Unplug fan motor or shut water off if water cooled.
C. Measure voltage between contactor side terminal of high pressure control and ground.
D. Switch ice machine on, observe pressure that the pressure control opens at, compare to
spec. Allow system to equalize, observe the pressure that the pressure control closes at,
compare to spec.

Check secondary voltage, it must be between 10 and 15.5 AC volts. Replace if no voltage is
output or if above or below the acceptable voltage..
Controller
The controller’s software operation is confirmed if it is functioning. Execute the test to confirm
its operation of the loads. Illumination of a diagnostic code (other than E) is not an indication of
controller failure. Each code requires its own diagnosis.

Test Procedures - Loads
Liquid Line Solenoid (remote only)
1. Test using the controller’s indicator lights. Put the controller into test mode (depress Off for 3
seconds then depress Clean for 3 seconds). At the end of the test cycle, the liquid line valve
will be powered and the Condenser Fan motor indicator light will be on. The liquid line valve
should be open at that time. If it is not, repeat the test but check the voltage to the liquid line
valve coil, it must receive full voltage at the liquid line lead connection at the end of the test. If
there is voltage and the valve does not operate, replace the valve coil. If there is no voltage,
check the controller high voltage harness connection. The liquid line solenoid lead is the top
wire. Check voltage from it to ground, at the end of the test, when the Condenser Fan indicator
light is On, there must be voltage from this pin to ground. Note: high voltage power is supplied
to the bottom pin from the contactor line. Refer to the machine wiring diagram as needed.
2. Test using an ohmmeter. Disconnect electrical power. Unplug liquid line coil from harness.
Measure liquid line coil resistance. If open, replace the liquid line valve coil.
This light will be ON when the liquid line
solenoid has power.

Test Procedures - Loads
Inlet Water Solenoid Valve
1. Test using the controller’s indicator lights. Shut unit off by holding the Off button for 3
seconds. Wait four minutes. Push and release the On button, observe the Water Solenoid
indicator light. After the unit drains the reservoir, the inlet water valve will be powered to refill
the reservoir. When it gets power, the indicator light will be ON. If the water valve does not
open to fill the reservoir when its indicator light is on, do a voltage check. Shut the unit down by
holding the Off button in for 3 seconds. Unplug the harness connection from the inlet water
valve. Wait four minutes. Push and release the On button to restart the machine. After the unit
drains the reservoir, the inlet water valve connection should receive full voltage. If it does, the
inlet water valve should be replaced. If there is no voltage, check voltage from the controller to
ground. The inlet water solenoid valve pin is 7. If there is voltage from that pin to ground, but
low voltage at the valve harness connection, the harness has a broken wire or poor connection
and must be replaced. If the voltage to ground is low, the controller should be replaced.
2. Test using an ohmmeter. Disconnect electrical power. Unplug coil from harness. Measure
coil resistance. If open, replace the inlet water solenoid.
Light is ON when inlet water
solenoid is in operation.

Test Procedures - Loads
Harvest assist solenoid
1. Test using the controller’s indicator lights. Push and release the Harvest button. The Hot
Gas indicator light will be on. At the same time the Harvest Assist Solenoid will be powered. If
the ice on the evaporator is thin, the solenoid will extend. If the ice is nearly full sized, the
solenoid will press against the ice until it releases from the evaporator, then the solenoid probe
will extend. If the probe extends, the solenoid is good. If not, do a voltage check. Unplug the
high voltage harness from the harvest assist solenoid. Attach a voltmeter to the harness
connector. Push and release the Harvest button. There should be full voltage at the connector.
If there is and the solenoid does not extend, replace the solenoid. If full voltage is not present,
check voltage at the controller. If there is no voltage, check voltage from the controller to
ground. The hot gas / harvest assist pin is 5. If there is voltage from that pin to ground, but low
voltage at the solenoid harness connection, the harness has a broken wire or poor connection
and must be replaced. If the voltage to ground is low, the controller should be replaced.
Note: The coil of this valve is internally rectified, will normally show infinite resistance when tested with
an ohmmeter.
This light will be ON during harvest.
Both the Hot Gas Valve coil and the
Harvest assist solenoid coil will have
power when this light is ON.
Hot Gas or Vapor Valve
1. Test using the controller’s indicator lights. If
the unit is running, or has been off for more
than 4 minutes, push and release the Harvest
button. The Hot Gas indicator light will be on
and the hot gas valve will be energized. The compressor will force discharge gas into the
evaporator inlet, warming it. If the evaporator inlet does not warm up, do a voltage check. Shut
the unit off by holding the Off button in for 3 seconds. Unplug the high voltage harness from
the hot gas solenoid. Attach a voltmeter to the harness connector. Wait 4 minutes. Push and
release the Harvest button. There should be full voltage at the connector. If there is and the
solenoid does not open, replace the solenoid coil. If full voltage is not present, check voltage at
the controller. If there is no voltage, check voltage from the controller to ground. The hot gas
pin is 5. If there is voltage from that pin to ground, but low voltage at the solenoid harness
connection, the harness has a broken wire or poor connection and must be replaced. If the
voltage to ground is low, the controller should be replaced.
2. Test with an ohmmeter. Disconnect electrical power. Unplug high voltage harness from hot
gas or vapor valve. Measure resistance of hot gas or vapor valve coil. If open, replace the coil.

Controller Differences
The controllers are programmed at the factory for the model they are installed on, they cannot
be moved from one model to another due to differences in:
Water purge time per setting
•
Maximum harvest time
•
Number of evaporator plates
•
The service controller has a selector switch that allows it to be used as a replacement part in
any of the Prodigy models in production at the time the controller was manufactured. As new
Prodigy models are introduced, those models will be added to the list of models new service
controllers will work with.
The Service Controller includes a selector switch. The switch must be set to the model the
controller is being installed on. As new models are introduced, their setting will be added to
service controllers produced after that point.
