3.11 SO218/318OPERATIONINFORMATION
FORSERVICEPERSONNEL
TheSO218/318 is acocktail/slush freezer.It is availablein 208-230 volt,either air-cooled or water-cooled.
Theair-cooled version hasfront-to-back airflow requiring threeinches of air spacein the frontand back for
properrefrigeration. This unitis not suppliedwith a pump, however, Stoelting does offerthe Fill-O-Matic II
(electric)and Fill-O-Matic III(gas) pumps FORTHE SO318. Thisfreezer is intendedfor use withnon-dairy
productsonly and will produce 15-18GPH.
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 fill switch on. 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
Oncethe freezer is full of mix, turn theclean-off-serve switch tothe “serve” position.The drive motorwill
start immediately. The compressorutilizes a 10second 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
werecommend to simply turn thefreezer off. Donot run thefreezer in “clean”overnight. Freeze downtime
will typically be 6-10 minutes depending on the type of product used and the starting product temperature.
3. PumpOperation
Whenthe mix levelin the hopperdrops below thebottom level probe,the solenoid valveopens 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
pump off and turn the freezer fill 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.
4. FillTimerOperation
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
dependent 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 compressor 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
Toremovespilled or driedmix from the freezerexterior,
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.
4.2PREVENTATIVEMAINTENANCE
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.
B. Weekly
1. Check“O”Ringsand rear sealfor excessive wear
and replace if necessary.
2. Removethedrip tray andinsert. Clean thedrip
tray and insert and front of the freezer with a soap
solution.
C. Monthly
CAUTION
THE FREEZER HAS AN AIR COOLED CON-
DENSERANDMUSTHAVEPROPERAIRCIRCU-
LATION. FAILURETOCLEAN THE CONDENSER
ON A REGULAR BASIS MAY RESULT IN SERI-
OUS FREEZER DAMAGE AND COULD VOID

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-
tionefficiencywillresult, causing extended run time
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 posi-
tion.
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
inthehopperorinthefreezerbarrelduringtheshut-
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
right side panel near the back. Remove black plug to
access.Toadjust use astraight bladed screwdriver.
Turnclockwise for a thicker productand counterclock-
wise for a thinner product. Allow 15-30 minutes for the
product to change consistency.
