3.11 SO328 OPERATION INFORMATION FOR
SERVICE PERSONNEL
The SO328 is a cocktail/slush freezer. It is available in
208-230volt,either air-cooled or water-cooled. Theair-
cooledversionhas front-to-back airflow requiring three
inches of air space in the front and back for proper
refrigeration. This unit is not supplied with a pump,
however, Stoelting doesofferthe Fill-O-MaticII (electric)
andFill-O-Matic III (gas)pumps. This freezeris intended
for use with non-dairy products only and will produce
15-18GPH.
1. Filling
To fill the freezer, pour mix into hopper until full. To fill
freezerswith the optionalFill-O-Matic pump, connect
the pump and turn the pump switch on, electric model
or turn the gas on, gas model. Then turn the pump
switch on, located on the freezer, this will open the
solenoidvalve and the freezerwillbegin to fill.The
liquid level control circuit is designed with a fill timer.
This timer is designed to shut the compressor off if
the top level probe is not satisfied before the timer
expires. If the top level probe is not satisfied before the
timer times out, it locks the compressor out and
freezing will not occur, if this happens, turn the fill
switch off and then back on, this will reset the timer.
2. Operation
Oncethe freezer isfull of mix,turn the clean-off-serve
switch to the “serve” position. The drive motor will start
immediately. The compressor utilizes a 10 second
delay-on-make/delay-on-break timer therefore, the
compressor will start 10 seconds later. The compressor
will continue to run until the drive motor torque switch is
satisfied, then after a 10 second delay stop. The drive
motor runs continuously in the “serve” or “clean” switch
positions. There is no night mode or standby mode. If
productis left inthe freezer overnightwe recommend to
simply turn the freezer off. Do not run the freezer in
"clean” overnight. Freeze down time will typically be 6-
10 minutes depending on the type of product used and
thestarting product temperature.
3. Pump Operation
When the mix level in the hopper drops below the
bottomlevelprobe, the solenoid valveopensand the
pump begins to fill until the top level probe is satisfied.
Whensatisfied, the solenoidvalve closes, andpump
will continue to run until shut off pressure is reached.
The electric pump will run until the pressure reaches the
cut-out pressure of the pump. A gas pump will continue
to run until the pressure in the mix line equals the gas
pressure of the pump. If you wish to use the product in
the hopper prior to cleaning, turn the mix pump off and
turn the freezer pump switch off. This will disable the fill
timer and allow the compressor to continue to run. Be
cautioned that once the hopper is empty, the barrel
could freeze up. Only run the freezer until the hopper is
empty or damage may occur.

9
4. Fill Timer Operation
The timer has ten dip switches, all switches placed in
the “on” position are added together to make up the
total time delay. This freezer leaves the factory with 64,
128 and 256 in the “on” position, this is a total of 448
seconds. The preset time should be enough to fill the
hopper up to the top level probe. Fill time may be depen-
dent on what style pump is employed. The purpose of
the timer is to disable the compressor if the mix supply
runs out. When the timer expires, the mix low light will
illuminate. If the mix low light is illuminated, the com-
pressor is locked out of the electrical circuit and will not
run. It may be necessary to change the timer settings
to more closely match the pumping capacity of your
pump.

4.1ROUTINECLEANING
Toremove spilled ordried mix fromthefreezer exterior,
simply wash in the direction of the finish with warm
soapy water and wipe dry. Do not use highly abrasive
materials as they will mar the finish.
4.2PREVENTATIVE MAINTENANCE
It is recommended that a maintenance schedule be
followedto keep the freezercleanand operating prop-
erly.
WARNING
NEVER ATTEMPT TO REPAIR OR PERFORM
MAINTENANCE ON FREEZER UNTIL THE MAIN
ELECTRICAL POWER HAS BEEN DISCON-
NECTED.
A. Daily
1. The exterior should be kept clean at all times to
preserve the lustre of the stainless steel. A mild
alkaline cleaner is recommended. Use a soft cloth or
sponge to apply the cleaner.
2. Removethedrip tray andinsert. Clean thedrip
tray and insert and front of the freezer with a soap
solution.
B. Weekly
1. Check“O”Ringsand rear sealfor excessive wear
and replace if necessary.
2. Clean filter.To remove lift up and pull bottom out and
down, then wash, dry and reinstall.
C. Monthly

1. Visually inspect the condenser for dirt by shining a
light through the coil from the fan side of the con-
denser.
2. If the condenser is dirty, using compressed air or
CO2 tank, blow out the dirt from the fan side of the
condenser.
3. Analternativemethod of cleaningthe condenser isto
usea condenser brush andvacuum.
NOTE
Ifthe condenser is not kept clean, loss ofrefrigera-

or soft product consistency.
4.3EXTENDEDSTORAGE
Referto the followingsteps for storageof the freezer
overany long period ofshutdowntime:
A. Turn CLEAN/OFF/SERVE switch to the OFF
position.
B. Disconnect (unplug) fromthe electrical supply
source.
C. Cleanthoroughlywith a warmdetergent all partsthat
come in contact with the mix. Rinse in clear water
and dry all parts. Do not sanitize.
NOTE
Do not let the cleaning or sanitizing solution stand

downperiod.
D. Remove,disassemble,andclean the frontdoor, and
agitator parts. Place the agitator blades and the front
agitator support bearing in a plastic bag with a moist
papertowel to preventthemfrom becoming brittle.
4.4CONSISTENCYADJUSTMENT
The consistency adjustment knob is located behind the
back panel. Remove the lower back panel to access.
