Operating the machine outside of the
limitations is misuse and can void the warranty.
Water Limitations:
An ice machine is a food manufacturing plant;
it takes a raw material, water, and turns it into
a food product, ice. The purity of the water is
very important in obtaining pure ice and in
maximizing product life. This is not intended
as a complete resource for water related
questions, but it does offer these general
recommendations:
1. Check with a water treatment specialist for
a water test, and recommendations regarding
filters and treatment.
2. In most cases, the water used to make ice
should be filtered or treated, depending upon
the water. There is no one type of water filter
that will be effective in all situations. That is
why a water test is important.
Scotsman Ice Systems are designed and
manufactured with the highest regard for
safety and performance. They meet or
exceed the standards of UL, NSF, and CSA.
Scotsman assumes no liability or responsibility
of any kind for products manufactured by
Scotsman that have been altered in any way,
including the use of any part and/or other
components not specifically approved by
Scotsman.
Scotsman reserves the right to make design
changes and/or improvements at any time.
Specifications and design are subject to
change without notice.

Location:
Typical Storage Bin with Extension and Bin Top
After uncrating and inspection, the unit is
ready for installation. It is important that the
machine be installed in a location where it has
enough space around it to be accessible for
service, and minimum of 6" be allowed at the
back for air circulation on air cooled models.
Try to avoid hot, dirty and crowded locations.
Be sure that the location for the machine is
within the limitations described on page 3.
Storage Bin:
Tip the storage bin on its back, using parts of
the carton to protect the exterior finish. Install
the legs into the threaded holes in the bottom
of the bin. Turn the leg levelers all the way in
preparation for leveling later. Return the bin to
the upright position, remove paper covering
the bin gasket.
Note: Do not push bin into position, but lift it
there. Pushing a bin, especially one with ice in
it, can cause damage to the legs and the leg
mounts.
Install the appropriate bin top on the bin,
according to the instructions for the bin top.
Ice Maker:
The machine is heavy, so the use of a
mechanical lift is recommended for lifting the
machine high enough to install on top of the
bin. After the unit is placed on the bin, line it
up so it is even with the back side. Secure the
machine to the bin with the hardware provided
with the machine.
Remove the front panel and remove any
shipping blocks.

CONFORM TO ALL APPLICABLE CODES
Water Inlet
Drains
Air Cooled Models: The recommended water
supply is clean, cold water. Use 3/8" O.D.
copper tubing, and connect to the single 3/8"
male flare at the back of the cabinet. This
connection supplys water to both ice making
systems. Install a hand valve near the
machine to control the water supply.
Water Treatment: In most areas, a water filter
of some type will be useful. In areas where the
water is highly concentrated with minerals the
water should be tested by a water treatment
specialist, and the recommendations of the
specialist regarding filtration and/or treatment
should be followed.
Water Cooled Models: A separate 3/8" O.D.
copper line is recommended, with a separate
hand valve to control it. It is connected to a
single 3/8" FPT condenser inlet at the back of
the cabinet. This connection supplys water to
both water cooled condensers. The water
pressure to all lines must always be above 20
psig, and below 120 psig.
Air Cooled Models: There is one 3/4" FPT
drain for both ice making systems at the back
of the cabinet, the drain line is of the gravity
type, and 1/4 inch per foot fall is an acceptable
pitch for the drain tubing. There should be a
vent at the highest point of the drain line, and
the ideal drain receptacle would be a trapped
and vented floor drain. Use only 3/4" rigid
tubing.
Water Cooled Models: In addition to the
above mentioned drain, a separate condenser
drain must be installed. There is one drain for
both ice making systems. Connect it to the
1/2" condenser drain connection at the back of
the cabinet.
Storage Bin: A separate gravity type drain
needs to be run, similar to the air cooled drain.
Insulation of this drain line is recommended.

FOR THE ELECTRICIAN
CONFORM TO ALL APPLICABLE CODES
The electrical power to the unit is supplied
through the junction box at the rear of the
machine.
Check the nameplate (located on the back
panel) for the voltage requirements, and for
the minimum circuit ampacity. The machine
requires a solid chassis to earth ground wire.
The ice maker should be connected to its own
electrical circuit so it would be individually
fused. Voltage variation must remain within
design limitations, even under starting
conditions.
All external wiring must conform to
national, state, and local electrical codes.
The use of a licensed electrician is
required to perform the electrical
installation.

START UP
Pre-Start Inspection
1. Remove the front and side service panels.
2. Check that the styrofoam shipping blocks
have been removed.
3. Inspect the interior of the machine for loose
screws or wires. Check that no refrigerant
lines are rubbing each other. Check that the
fan blade turns freely (air cooled).
4. Check that the unit is installed correctly
according to the final check list (page 8).
The following procedure applies to each of the two separate ice making systems.
Start Up
1. Go through the prestart inspection.
2. Open the hand valve, observe that water
enters the water reservoir, fills the tube from
the reservoir to the evaporator, and then shuts
off. Check for leaks.
3. Switch the master switch on.
The electrical start up sequence is now on
automatic.
A. There should be a short (15 second) delay
before the gearmotor starts.
B. After the gearmotor starts, the compressor
will start.
4. On air cooled models, the condenser will
begin to discharge warm air, on water cooled
models, the water regulating valve will open,
and warm water will be discharged into the
drain.
5. The unit should soon be making ice, if
desired, the low side pressure of each system
can be checked: it should be 30 psig + or - 4
psig.
The suction line temperature at the
compressor is normally very cold, nearly to the
point of frost up to the compressor body, but
not on it.
The air cooled discharge pressure will depend
upon air and water temperatures, but should
be between 200 psig and 280 psig.
The water cooled discharge pressure should
be constant at about 220 psig.
The above numbers are for new, clean
machines, you can expect to see some values
higher, and some lower between different
units.
6. THERE ARE NO ADJUSTMENTS TO
MAKE, so replace the panels.
7. Clean and/or sanitize the storage bin
interior, wipe off the exterior with a clean,
damp cloth.
8. Give the owner/user the service manual,
instruct him/her in the operation of the unit,
and make sure they know who to call for
service.
9. Fill out the manufacturers registration card,
and mail it to the Scotsman Factory.
10. Fill out the field quality audit form, and mail
it to the Scotsman factory.

ELECTRICAL SEQUENCE
Refer the wiring diagram as needed.
The following description applies to either one
of the two ice making systems. They operate
independently of each other.
If the machine is switched off at the master
switch, but is otherwise ready to go, switching
the master switch to on does the following:
• The bin empty light on the circuit board
goes on
• There is a 15 second delay
• If there is enough water in the reservoir, the
circuit board will allow the machine to start
up.
Start up consists of:
• The compressor relay and auger motor
relay become energized, connecting power
to the windings of the auger motor.
• The auger motor starts, and the centrifugal
switch closes, connecting power to the
compressor contactor coil.
• The contactor is energized, connecting
power to the compressor, and the
compressor starts.
• As ice goes past the ice level sensors, the
bin empty light will stay on, and the
machine will continue to run, unless the ice
stays between the sensors for more than
15 seconds (bin full). At that point, the bin
empty light goes out, and the machine
shuts down.
Shut Down consists of:
• The compressor relay opens.
• The compressor contactor opens
• The compressor stops
• The auger motor is run by the circuit board
for 2.5 more minutes, clearing out ice in the
evaporator, and then
• The auger motor relay opens, and the
auger motor stops.
If the ice level sensor is clear (bin empty) for
more than 15 seconds, the machine will start
up again.
Another purpose of the circuit board is to turn
the machine off if there is not enough water in
the machine.
• When the water level in the reservoir falls
below the water level sensor, the machine
will "shut down"
• When the water refills the reservoir, the
machine will start up again.
Separate from the circuit board:
• If the high pressure control (cut out switch)
opens, the machine will stop immediately
(through the relays on the circuit board) and
cause the reset switch on the circuit board
to light up. It must be manually reset at the
control and at the reset switch on the circuit
board.
• If the low pressure control (cut out switch)
opens, the machine will stop immediately
(through the relays on the circuit board) and
cause the reset switch on the circuit board
to light up. It must be manually reset at the
control and at the reset switch on the circuit
board.
• If the spout switch opens, the machine will
stop immediately (through the relays on the
circuit board) and cause the reset switch on
the circuit board to light up. After it recloses
the reset switch on the circuit board must
be manually reset.
• Each master switch is the manual control
for each system, but it is not a service
disconnect.

OPERATION: Water
Water enters the machine through the 3/8"
male flare at the rear of the cabinet, splits into
two separate lines, flows to a strainer at each
reservoir and then to each water reservoir
which it enters through the float valve. The
water then goes out the bottom of the
reservoir tanks to the bottom of each
evaporator.
Reservoir overflow or evaporator
condensation is routed to the drain.
Water cooled models have a separate water
circuit for the cooling water: it enters the fitting
at the rear, divides and goes to the two water
regulating valves, then through each water
cooled condenser, reconnects into one drain
and down the drain.

OPERATION: Refrigeration
The following description applies to each of the two separate ice making systems.
Beginning at the compressor, the refrigerant
502 is compressed into a high temperature
gas. The discharge line directs this gas to the
condenser. At the condenser (air or water
cooled) the gas is cooled by either air or water
and it then condenses into a liquid. This high
pressure liquid then goes through the liquid
line to the expansion valve. The thermostatic
expansion valve meters liquid refrigerant into
the evaporator, the volume of liquid refrigerant
depending upon the temperature of the
evaporator; warmer evaporators get more
refrigerant and colder evaporators get less.
At the evaporator, the refrigerant enters an
area of relatively low pressure, where it can
easily "boil off" or evaporate. As it
evaporates, it absorbs heat from the
evaporator and whatever is in contact with it
(such as the water inside it). After the
evaporator, the refrigerant, now a low
pressure vapor, goes through the suction line
back to the compressor, where the cycle is
repeated.

MAINTENANCE AND CLEANING
The FM2400 is made up of two separate ice makers; to properly clean and maintain the FM2400,
these steps must be followed for both systems.
//////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////////
A Scotsman Ice System represents a sizable investment of time and money in any company’s
business. In order to receive the best return for that investment, it MUST receive periodic
maintenance.
It is the USER’S RESPONSIBILITY to see that the unit is properly maintained. It is always
preferable, and less costly in the long run, to avoid possible down time by keeping it clean;
adjusting it as needed; and by replacing worn parts before they can cause failure. The following
is a list of recommended maintenance that will help keep the machine running with a minimum of
problems.

SERVICE DIAGNOSIS: Condition - No Ice Being Produced
STATUS: NOTHING OPERATES
A. Check: Voltage to the unit, restore it if there is none. Compare to the nameplate.
B. Check: The master switch, switch ON if off.
C. Check: The 3 reset switches, (circuit board, high and low pressure): depress and release
each switch. If the still does not start, check: the spout switch; the high and the low side
pressures.
D. Check the low pressure cut out, if closed, go to E; if it is open, it could be due to:
• Low refrigerant charge
• The auger not turning
• Restricted system
• TXV not opening
1. Check the low side pressure, the low pressure cut out opens at pressure below 4 psig.
If open, reset and:
a. Check if the auger is turning, if it is not, remove the gearbox and:
Check for internal damage, repair and replace in the machine.
b. Check for low charge, add some refrigerant, if the unit will operate,(normal
low side pressure being about 30 psig) stop and look for a leak, repair, replace the
drier, evacuate, and weigh in the nameplate charge. If, with added charge, the unit
does not operate:
Check for a restricted system, replace the drier, evacuate, and weigh in a
nameplate charge.
Check for a Thermostatic Expansion Valve that does not open, if defective,
replace it. Replace the drier, evacuate, and weigh in the nameplate charge.
E. Check the high pressure cut out, if closed, go to F; if open check:
1.The pressure control opens at 450 psig. Check the high side pressure, reset the control,
and observe: on water cooled, that water soon begins to flow from the condenser drain;
or, on air cooled, that the fan is forcing air through the condenser. If the unit trips out on
pressures below 450 psig, replace the control. If the pressures rise above the trip out
point, and the unit shuts down:
a. Check for adequate water flow on water cooled, if adequate, clean the interior
of the condenser. If the pressures are still too high replace the water regulating valve.
b. Check for adequate air flow on air cooled. Clean the condenser and (if used) the
filter. If the air flow is poor because of the installation, advise the user that the unit
should be moved, or the air around it kept cooler.
Check the fan motor for tight bearings and proper rotation.
Check that the fan blades are clean, and the fan secure to the fan motor shaft.
F. Check the spout switch. It opens from excess pressure of ice inside the ice chute: this should
only happen when the machine does not shut off when the ice storage bin is full. This switch will
reset when the ice melts, but the machine will not resart until the reset switch on the circuit board
is pressed, if the spout switch is closed, check G.
G. Check the water level in the reservoir. The machine will not run if there is not enough water in
the reservoir.
1. Restore/adjust water level. See the next step.

Note: The gearcase cover, output gear,
bearings and output shaft are a pressed
together assembly. Replace as a unit.
C) Inspect the oil, gears, and bearings. If the
oil level and condition is acceptable, quickly
check the gears and bearings. They are likely
to be fine if the oil is.
If there is evidence of water in the oil (rusty
bearings and gears; the oil having a creamy
white appearance; oil level too high) carefully
inspect the bearings and gears. If in doubt
about the condition of a part, replace it. The oil
quantity is 14 fluid ounces, do not overfill.
Note: The gears and bearings are available
only as pressed together sets.
D) After replacing parts as required, (if any)
reassemble the gearcase. The two smaller
gears and the oil should be in the lower case,
the output gear will be with the cover. As you
lower the cover onto the lower case, the
cover will have to be moved closer to the
second gear after the output gear has cleared
the second gear top bearing.
E) After the case is together, and the locating
pins are secure in both ends, replace all cap
screws.
Note: If the gearcase cover or the gearmotor
was replaced, the replacement part MAY
HAVE BEEN shipped with a certain number of
shims. The number of shims used must
match the number written on the gearcase
cover. If there is no number written on the
