chanical parts. Adjustable and removable legs are under cabinet.
SEALED REFRIGERATION SYSTEM, Provides quiet, efficient operation
of the machine, Compressor motor is spring mounted and the worm
motor is rubber mounted for quiet operation. Compressor motor is cov-
ered 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 cyclinder and turns to ice on the inside of this cyclinder.
Ice from the refrigerated walls of this cyclinder is extruded past the
ice breaker at the top of the cyclinder through a side opening by means
of a stainless steel auger driven by a motor through a V belt and a gear
reduction drive.
SCOTSMAN Model SF-75WSH is completely automatic. A manual switch
on the front starts the machine, and from then on, produces flakes auto-
matically. When the storage binfills, the machine automatically shuts
off and starts up again when ice is taken from the storage compartment.

INSTALLATIONS
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
practical place to install an air-cooled condensing unit, as grease is
almost always present and makes cleaning of the condensing unit diffi-
cult. 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
impair the efficiency of the unit. The storeroom must be kept above
50" 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 and
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 to eliminate any possible damage to
the machine.
UNCRATING OF MACHINE: The complete machine comes in one crate,
After the crate is removed, inspect for concealed damage. When installing
the machine. Remove the bottom skids by removing all bolts Then check
all refrigerant lines for rubbing or touching other surfaces. Also check
for possible transportation damage. Check for free movement of ice worm.
PRE-INSTALLATION CLEANING: Before machine is in final location,
remove warranty card and other information from machine compartment.
Remove top service door, water reservoir cover, and packing under
float. Then leave cover off for float adjustment after machine is
installed.
WATER SUPPLY. The recommended water supply line is 1/4 inch OD
copper tubing for SF-75WSF. Connect to cold water supply line with
regular plumbing fittings, with 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.
The water supply line connects to the 1/4 inch flare fitting on the machine.
Water supply must be installed to conform 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 tubing.
Must be run to an open trapped and vented drain. If drain is a long run,
allow a 1/4 inch pitch per foot. Drain must be installed to conform
with local code.
INSTALLATION
ELECTRICAL CONNECTIONS:
SF -75WSH
115 Volts, 60 Cycle, 1 Phase
15 Amp. Circuit
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 overilow.
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 holding a handful of ice around the bulb until the machine
shuts off. One minute 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, 45 degrees cut in.
Check pressure settings at the time of start-up. Head pressure normal
at 135 PSI. The frost line should extend 8' out of the accumulator if
properly charged with refrigerant and suction pressure will range between
15 and 16 PSI with 50° F.inlet water.
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 connection is available on low side service valve. 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 8' out of the accumulator after fifteen minutes of operation.
Factory charge 25 oz. refrigerant 12.

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.
A removable overflow pipe is installed in the water reservoir for clean-
ing the reservoir as well as preventing damage should the inlet water
valve fail.
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 overflow pipe. A con-
densate drip pan is connected to the drain circuit to automatically dispose
of condensate moisture,
A water strainer must be installed in the supply line. Use strainer sent
with machine.
ELECTRICAL SYSTEM: The super Flaker Model SF-75 is designed to
work on standard voltage--115/60/1.
Special voltage requirements are available on special order. Therefore,
always check nameplate for this information before checking electrical
supply.
Nameplate voltage should not vary more than plus or minus 10 percent.
The electrical circuit consists of condensing unit, drive motor, storage
bin thermostat, ON and Off switch and micro (safety) switch.
A. CONDENSING UNIT: The starting capacitor and starting relay are
housed and fastened to the motor compressor.
B. DRIVE MOTOR: Model SF-75 Flakers are equipped with standard
1/2" shaft, 1/4 HP, capacitor start, induction motors. These motors
turn counter-clockwise and may be replaced with any standard make
motor corresponding to the nameplate rating. (Be sure motor runs
counter -clockwise viewed from the shaft end.) NEMA 48 Frame.
C. STORAGE BIN THERMOSTAT: White Rodgers control located on
frame assembly. Factory settings 35° cut-out, 45 cut-in. This control
shuts off complete machine when ice in storage bin builds up to control.
D. MICRO SAFETY SWITCH: The micro switch is located in the top of
the ice chute. The switch is operated by a plate in top of the ice chute by
the ice backing up in the chute should the storage bin thermostat fail. Micro
switch will shut off the condensing unit only, when operated.
E. ON-OFF SWITCH: A manual on-off switch with built-in thermal
overload protection to prevent drive motor failures is used. See overload
chart for correct size. (Page No. 29)

MAINTENANCE INSTRUCTIONS - FLAKERS
THE FOLLOWING MAINTENANCE MUST BE ACCOMPLISHED
TWO TIMES PER YEAR ON ALL SCOTSMAN SUPER FLAKERS,
CALL YOUR AUTHORIZED SCOTSMAN SERVICE DEPART -
MENT.
1. Check and clean water strainers and float valve, Depress
float valve to insure full stream of water.
2. 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.
3. 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:
Set main switch to OFF,
Remove all ice from storage bin,
Turn off water supply or block float. Drain reservoir
by removing overflow tube (gray plastic tube) in
reservoir. Replace overflow tube.
4. Set main switch to ON and pour cleaning solution
into reservoir. Do not fill above overflow tube.
Models SFl «4 SF75--Use 4 oz. of Scotsman
cleaner and! gt. hot water.
Model SF2 & SF3--Use 6 oz. of Scotsman
cleaner and 11/2 qt. hot water.
Model SF5--Use 8 oz. of Scotsman cleaner &
2 gts. hot water,
Model SF8--Use 160z. of Scotsman cleaner &
4 gts, hot water.
Continue to make ice on solution until the solution is
used up and reservoir is empty.
6. Set main switch to Off. Remove overflow tube, wash
and rinse reservoir, replace overflow tube, turn water
on or remove float block.
œNH
un
7, 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,
8. 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.
9. Turn MAIN SWITCH to On. Replace Service Door,
Unit is ready for normal operation.
Section
F 5-7
Page 51
MAINTENANCE INSTRUCTIONS (Continued)
B. If heavy mineral deposits on auger and walls, or sedi-
ment at inlet to freezer are encountered, clean by
pouring strong solution {1/2 acid-1/2 water) into res-
ervoir and operate drive motor only for agitation. Al-
low 1/2 hour or longer as required. Drain by dis-
connecting tygon at water inlet to freezer.
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. Change oil in gear reducer. Use Mobiloil 600W or equiva-
lent good grade of gear oil with a viscosity of 125 to 190,
For unit with grease fittings use Mobilgrease BRB No. 1
or any good grade ball bearing grease. Particularly im-
portant when there is evidence that water has gotten into
gear housing. Remove gear reducer to facilitate.
6. Oil drive motor, Use SAEIO oil.
7
‚ Check top beariac of freezing tube. hemove 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.
8. Check and adjust V belt tension,
9. Clean air-cooled condenser. Inform customer to clean fre-
quently. Always shut off machine when cleaning,
10. Oil condenser fan motor when possible.
Il, Check for refrigerant leaks and proper frost line. Should
frost out of accumulator at least one-half way to compres -
sor, and in some areas back to service valve,
12. Check for water leaks, Tighten drain line connections,
Run water down bin drain line to make sure it is open.
13. Check quality of ice. Ice should be wet when formed, but
will cure rapidly to normal hardness in bin,
l4. Check thermostat and pressure plate cut off, Micro switch
cuts off only compressor. Bin thermostat should be set at
109 differential and should keep entire machine off at least
twenty minutes in high ambients (longer in low) during norm-
al operation,
