SCOTSMAN Super Flakers are designed for restaurants, super markets, soda
fountains, hospitals, bakeries, fish markets, poultry stores, packing plants,
etc. It is the finest Ice Maker on the market today. It will work 24 hours a
day for you, or only as needed. It produces the highest quality ice available
at any price.
Approximately 500 pounds of SCOTSMAN crushed ice is delivered each 24
hours to the storage bin for immediate use.
SCOTSMAN Super Flakers are easily installed requiring only standard water,
drain and electrical connections.
ATTRACTIVE COMPACT CABINET. Grey hammerloid finish with chrome
trim, rounded corners, and removable panels for easy access to mechanical
parts. Adjustable and removable legs are under cabinet.
SEALED REFRIGERATION SYSTEM. Provides quiet, efficient operation
of the machine. Compressor motor is internally spring mounted for quiet
operation. Compressor motor is covered by a full 5-Year Warranty.
HOW IT WORKS. An exclusive patented ice-making system, wherein water
in the constant level float reservoir is fed to the bottom end of the freezing
cylinder and turns to ice on the inside of this cylinder. Ice from the refrig-
erated walls of this cylinder is extruded past the ice breaker at the top of the
cylinder through a side opening by means of a stainless steel auger driven
by a gearmotor drive.
All SCOTSMAN Models SF1J and SF1WSJ are completely automatic. A
manual switch on the front starts the machine, and from then on, produces
flakes automatically. When the storage bin fills, the machine automatically
shuts off and starts up again when ice is taken from the storage compartment.
Model No. SF1J is a continuous flow type machine, and is manually started
by an OFF and ON switch located on the front of the cabinet as are the SEF-1WSJ
models. Since the SF-1J does. not have its own attached bin, it is necessary
to use an auxillary bin such as the Model SB-500 SCOTSMAN Super Bin for ice
storage. A bin thermostat is mounted in each SF -1J continuous flow type
machine for the purpose of mounting control bulb from machine to bin.

PREPARATION FOR INSTALLATION
UNCRATING
The entire unit comes in one crate. Upon delivery a visual inspection of
the crate should be made and any severe damage noted should be reported
to the delivering carrier and a concealed damage claim filed subject to
internal inspection with carrier representative present. Remove crate
by pulling nails driven through sides of crate into the bottom skid. A
nail puller is best suited here. Next remove (4) four bolts from under-
side of skid which connect to complete unit base. Unit now free from all
crating.
Remove all service doors and panels.
Remove water reservoir cover and take out paper packing around float
ball.
Remove leg packages in compartment base and install 4 legs in unit base
sockets. On continuous flow models with separate storage bins, legs are
put on companion machine stand, not on Ice Maker.
Check motor compressor hold down nuts to insure motor compressor rides
snug on mounting pads.
Remove water strainer from storage bin for installation on unit or in
water supply line feeding unit.
Open electrical control box and prepare for hook up, use knock outs, cord
connectors etc. Then check unit nameplate voltage against building source
voltage and make sure they correspond. Caution - Improper voltage supplied
to units will void your warranty protection.
Select unit location prior to hook up of water drain and electricals in acçord-
ance with local and national codes. Minimum room temperatures is 50
Fahrenheit. On air cooled models, select well ventilated location.
Remove warranty card and Users manual from storage bin, then wipe bin
clean with damp cloth.
Fill out warranty card completely including model and serial numbers: as
taken from aluminum plate found behind front service panel and forward to
Scotsman Factory using self mailing card.
Level unit with adjustable legs.

SELECTING LOCATION
UNDER BAR INSTALLATIONS: Locate, if possible, so left end panel is
accessible. Locate so proper circulation can be attained around the unit
and behind it at least four inches.
KITCHEN INSTALLATIONS: As a rule, the kitchen is not the most prac-
tical place to install an air-cooled condensing unit, as grease is almost
always present and makes cleaning of the condensing unit difficult. Do not
locate near range or steam table or other heating devices that may be used
in the kitchen.
STOREROOM INSTALLATIONS: Be sure storeroom is of adequate size
and properly ventilated. A small, poorly ventilated room will greatly im-
pair the efficiency of the unit. The storeroom must be kept above 50 degrees
in the winter months.
BASEMENT INSTALLATIONS: Locate machine in the coolest place.
Locate machine in a dry place. Keep away from furnace and boiler room.
Keep away from service chutes and runways; also coal or other dust of any
kind. If the machine is set over a floor drain, block the machine up enough
to level it. If there is any chance of basement flooding, block the machine
up enough to eliminate any possible damage to the machine.
WATER SUPPLY: The recommended water supply line is 1/4 inch I.D.
copper tubing for SF-1. Connect to cold water supply line with regular
plumbing fittings, with a shut-off valve installed in an accessible place
between supply line and machine. A water strainer must be installed with
the unit and mounted with clean-out plug down. Locate the strainer next
to the machine with the arrow in the direction of the flow. Most plumbing
codes also call for double check valves in the supply water line, partic-
ularly for water-cooled models.
On air-cooled models the water supply line connects to the 1/4 inch flare
fitting on the machine. On water-cooled models connections are made to
a 3/8 inch male pipe nipple inside of the machine compartment. Incoming
water goes through the water regulating valve first and then to the water-
cooled condenser. Observe arrow on water regulating valve. Water supply
must be installed to confrom with local code. In some cases a licensed
plumber and/or a plumbing permit will be required.
DRAIN: The recommended drain from the bin is 5/8 inch OD copper tub-
ing. Must be run to an open trapped and vented drain. If drain is a long
run, allow 1/4 inch pitch per foot. Drain must be installed to conform
with local code. Run separate line for condenser discharge water on
water-cooled models.

ELECTRICAL CONNECTIONS:
SF1WSJ
115 Volts, 60 Cycle, 1 Phase
20 Amp. Circuit
12 Gauge wire should be used for electrical hook-up. Conductors
with third or ground wire are desirable.
Be certain that the Super Flaker is on its own circuit and individually
fused. The maximum allowable voltage variation should not exceed 10
per cent of the nameplate rating even under starting conditions. Low
voltage can cause erratic operation and may be responsible for serious
damage to the overload switch and motor windings.
All external wiring should conform to the National Underwriters and
local Electrical Code requirements. Usually an electrical permit and
the services of a licensed electrician will be required.

SERVICE
STARTING THE MACHINE: When the machine is placed and inspected as
per instructions and all plumbing and electrical connections are completed
and tested, turn on the water supply. Be sure the float cover is removed
to check on the float operation and water level in the water reservoir. Be
sure the water reservoir is filled before starting the machine. Water
level should be 1/4 inch below the reservoir overflow.
When this is completed, turn on the manual switch on the front of the cabinet
and the machine is in automatic operation. In two to three minutes ice will
start dropping off the worm shaft and out the ice chute. Let the machine
operate for at least 30 minutes and check for any excess noise other than
the normal compressor .noise. Test the ice storage control bulb by hold-
ing a handful of ice around the bulb until the machine shuts off. One min-
ute should be normal for the control to function. Within minutes after the
ice is removed, the bulb will warm up and the machine will automatically
start up. The control is factory set and should not be reset until this test
is made. Normal setting of this control should be approximately 35 degrees
cut-out and 45 degrees cut-in.
Check pressure settings at the time of start-up. On the water-cooled models
set the head pressure at 135 PSI. On the air-cooled models the head pressure
will vary between 130 and 145 PSI head pressure. The frost line should
extend out of the accumulator if properly charged with refrigerant and suction
pressure will range between 14 and 16 PSI with 50° F inlet water.
Check the hand reset low pressure control setting. This safety device
should be set at approximately 5 PSI below normal operating suction pressure
and should cut off in case of interruption in water supply, shortage of refrig-
erant, low ambient or any other cause of abnormally low suction pressure.
Explain the machine to the owner, showing him how the machine works and
go over the owner's instruction sheet with him. Answer all the owner's
questions about the machine, and do not leave with any doubt in the owner's
mind about the machine, how to operate it or where to reach you should he
need service on the machine. Call back the next day to check the machine
again and answer any other questions the owner may have.
Service gauge connections are available on both high and low side service
valves on water cooled models, suction valve only on air cooled models.
To install gauges to any of these connections, use lines with tire type service
valve adapter. Purge free of any non-condensable gases before starting any
test operation.
REFRIGERANT CHARGE: The below refrigerant charge is approximate.
When charging, set at 135 PSI head pressure and charge so that the frost
line extends out of the evaporator and into the accumulator after fifteen
minutes of operation.

SERVICE
WATER SYSTEM: A water level is maintained in the water reservoir by
a float operated valve. Water is piped from the water reservoir to the
freezing chamber by a gravity feed line maintaining an equal water level.
The water reservoir is equipped with a 2 inch air gap to prevent back
siphoning and meet all health codes.
The water level in the water reservoir is adjusted by bending float arm.
The water level should be set 1/4 inch below the moulded in overflow well.
A water strainer must be installed in the supply line. Use strainer sent
with machine.
ELECTRICAL SYSTEM: The super Flaker Model SF-1J is designed to
work on standard electrical supply 115 volts, 60 cycle single phase.
Supply voltage should not vary more than plus or minus 10 percent
over nameplate rating.
Special voltage requirements are available on special order. There-
fore, always check nameplate for this information before connecting
electrical supply.
The electrical circuit consists of condensing unit, freezer gear motor,
storage bin thermostat ON and Off switch and spout micro (safety) switch.
A. CONDENSING UNIT: The starting capacitor and starting relay are
hous ed and fastened to the motor compressor.
B. GEAR MOTOR TO FREEZER: Models SF1J are equipped with
a 1/10 horsepower direct drive gearmotor. A speed sensing switch
mounted on top of the motor of the gear unit will open and stop the
compressor when the RPM of the gearmotor is less than 900, At 1200
RPM it will close, starting the compressor.
In an actual operation any condition that may cause excessively hard
ice and overloads within the freezer assembly, water interruptions,
cold ambients, etc. is transmitted to the gearmotor reducing it's
speed. When gearmotor slows down to approximately 900 RPM the
speed sensing switch opens the electrical circuit to the compressor.
The compressor stops and no more ice is produced, meanwhile the
gearmotor continues to run, clearing the overload condition and
gradually resumes full speed. At 1200 RPM gearmotor speed sensing
switch closes compressor circuit causing the normal icemaking
process to begin once more.
Any freeze up possibility is therby automatically cleared out by the
gearmotor,
Section
SF-1
Page 20
C. STORAGE BIN THERMOSTAT: Thermostat control body is located
in electrical control box. The thermostat sensing tube is threaded into
the ice storage bin where it automatically stops the icemaker when ice
bin fills to sensing tube level and restarts icemaker when ice is removed.
Factory settings are 35° cut out, 45° cut in.
Altitude correction begins at 2, 000 feet, cut in and cut out screws
should be adjusted equally, not more than 1/4 turn at a time.
D. MICRO SAFETY SWITCH: The micro switch is located in the top
of the ice chute. The switch is operated by a pressure plate inside the
ice chute. Ice backs up in the chute if the storage bin thermostat fails.
Micro switch will shut off the condensing unit only, when operated.
E. ON-OFF SWITCH: A manual on-off switch is located in control box.
F, SAFETY CONTROL: High head pressure. On water cooled models
only. Factory set to stop entire icemaker if head pressure reaches
190# PSIG. Manual reset, adjustable.
G. SAFETY CONTROL:- Low back pressure. Used on both models, this
control is set to electrically '"open'' at 2# PSIG, stopping entire icemaker.

4, Lightly grease bottom half of new water seal and insert face up
approximately 1/2' in bottom of freezer tube.
5. Insert bottom bearing in bottom of freezer tube, force
approximately 1/8" past bottom tube end. This will allow
the positioning ring on fiber adaptor to properly position
freezer tube when tightening up the three mounting bolts.
6. After securing mounting bolts, put new top half of water
seal on worm shaft the same way as the old seal was removed.
7. Carefully insert worm shaft assembly in freezer tube and into
spline coupling on bottom.
8. Replace ice breaker screws, insulation pieces and unit is
ready to resume operation.

MAINTENANCE INSTRUCTIONS - FLAKERS
THE FOLLOWING MAINTENANCE SHOULD BE SCHEDULED
THREE TIMES PER YEAR ON ALL SCOTSMAN SUPER FLAERS.
CALL YOUR AUTHORIZED SCOTSMAN SERVICE DEPARTMENT.
l.
д.
Check and clean water strainers and float valve. Depress
float valve to insure full stream of water.
Check water level and machine level, keep water level be-
low overflow, but as high as possible and still not run out
of spout opening with machine off. Water droplets come out
of spout with ice at all times. Adjust as required.
Clean reservoir and interior of freezer using SCOTSMAN
Ice Machine Cleaner,
A. If machine has been cleaned regularly and no problems
such as dry ice or chatter are noticed, clean as per
the following instructions:
a. Set main switch to OFF.
b. Remove all ice from storage bin.
с. Turn off water supply or block float, Drain reservoir by
disconnecting tube between reservoir and freezer. After
draining, reconnect tubing.
d. Set main switch to ON and pour cleaning solution
into reservoir. Do not fill above overflow tube.
Models SF1 8% SF75--Use 4 oz. of Scotsman
cleaner and 1 qt. hot water.
e. Continue to make ice on solution until the solution is
used up and reservoir is empty.
f. Set main switch to Off. Remove overflow tube, wash
and rinse reservoir, replace overflow tube, turn water
on or remove float block.
g Turn MAIN SWITCH to ON. Let unit run for at least
(15) minutes to flush out any cleaning fluid. Check
ice for acid taste .-- run until ice tastes sweet.
h. Turn MAIN SWITCH to OFF, Add hot water to ice
bin, using this melt water, thoroughly wash and rinse
all surfaces within the storage bin.
1. Turn MAIN SWITCH to On. Replace Service Door.
Unit is ready for normal operation.

MAINTENANCE INSTRUCT IONS (Continued)
NOTE: Cleaning requirements vary according to local water
conditions. Visual inspection of the auger before and after
cleaning will indicate best procedure to be followed in local
areas.
4. Check high and low side pressures. On air-cooled models
head pressures range between 130 and 145 PSI. Suction
pressure should be above 12 PSI and will range up to 16
PSI depending upon water and ambient temperatures.
5. Check gearmotor operation. Normal running temperatures
are in the area of 160 farenheit, which is hot to the touch.
Check operation of centrifugal switch and the micro switch
it actuates. When micro switch is actuated, compressor
stops, gearmotor continues to run.
6. Check top bearing of freezing tube. Remove retainer ring
around edge of stamped brass cap. If moisture is around
bearing, wipe up and remove grease. Add new grease.
Use Beacon No. 325. Replace cap and retainer ring.
7. Clean air-cooled condenser. Inform customer ta clean I
frequently. Always shut off machine when cleaning 2
8. Oil condenser fan motor when possible.
9. Check for refrigerant leaks and proper frost line. Should
frost out of accumulator at least onc -half way to compressor,
and in some areas back to service valve.
10. Check for water leaks. Tighten drain line connections.
Run water down bin drain line to make sure it is open.
11. Check quality of ice. Ice should be wet when formed, but
will cure rapidly to normal hardness in bin.
12. Check thermostat and pressure plate cut off in spout.
Micro switch cuts off only compressor. Bin thermostat
should be set at 10° differential and should keep entire
machine off at least twenty minutes in high ambients
(longer in low) during normal operation. Settings are
Ô :
35° cut out, 45 cut in.
