3.11 SO328 OPERATION INFORMATION FOR
SERVICE PERSONNEL
The SO328 is a cocktail/slush freezer. It is available in
208-230 volt, either air-cooled or water-cooled. The air-
cooled version has 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 does offer the Fill-O-Matic II (electric)
and Fill-O-Matic III (gas) pumps. This freezer is intended
for use with non-dairy products only and will produce
15-18 GPH.
1. Filling
To fill the freezer, pour mix into hopper until full. To fill
freezers with the optional Fill-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
solenoid valve and the freezer will begin 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
Once the freezer is full 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
product is left in the freezer overnight we 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
the starting product temperature.
3. Pump Operation
When the mix level in the hopper drops below the
bottom level probe, the solenoid valve opens and the
pump begins to fill until the top level probe is satisfied.
When satisfied, the solenoid valve closes, and pump
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.
