A Few Words About Safety
Safety Information
Read and understand the entire manual before
operating or maintaining Stoelting equipment.
This manual provides the operator with information
for the safe operation and maintenance of Stoelting
equipment. As with any machine, there are hazards
associated with their operation. For this reason safety
is emphasized throughout the manual. To highlight
specific safety information, the following safety defini-
tions are provided to assist the reader.
The purpose of safety symbols is to attract your at-
tention to possible dangers. The safety symbols, and
their explanations, deserve your careful attention
and understanding. The safety warnings do not by
themselves eliminate any danger. The instructions
or warnings they give are not substitutes for proper
accident prevention measures.
If you need to replace a part, use genuine Stoelting
parts with the correct part number or an equivalent
part. We strongly recommend that you do not use
replacement parts of inferior quality.
WARNING
The signal word “WARNING” indicates a potentially
hazardous situation, which, if not avoided, may result
in death or serious injury and equipment/property
damage.
CAUTION
The signal word “CAUTION” not preceded by the
safety alert symbol indicates a potentially hazardous
situation, which, if not avoided, may result in equip-
ment/property damage.
NOTE (or NOTICE)
The signal word “NOTICE” indicates information or
procedures that relate directly or indirectly to the
safety of personnel or equipment/property.

2.2 SHIPMENT AND TRANSIT
The machine has been assembled, operated and in-
spectedatthefactory.Uponarrivalatthefinaldestination,
the entire machine must be checked for any damage
which may have occurred during transit.
With the method of packaging used, the machine should
arriveinexcellentcondition.THECARRIERISRESPON-
SIBLE FOR ALL DAMAGE IN TRANSIT, WHETHER
VISIBLEORCONCEALED.Donotpaythefreightbilluntil
the machine has been checked for damage. Have the
carrier note any visible damage on the freight bill. If
concealeddamageand/orshortageisfound later, advise
the carrier within 10 days and request inspection. The
customermustplaceclaimfordamagesand/orshortages
in shipment with the carrier. Stoelting cannot make any
claims against the carrier.
2.3 MACHINE INSTALLATION
Installation of the machine involves moving the machine
close to its permanent location, removing all crating,
setting in place, assembling parts, and cleaning.
A. Uncratethemachine.
B. Determinethelocationofthemachine.Thelocation
must be able to hold 350 lbs.
C. Accuratelevelingisnecessaryforcorrectdrainage
of machine barrel and to insure correct overrun.
Placeabubblelevelontopofthemachineateach
corner to check for level condition. If adjustment
is necessary, level the machine by turning the
bottom part of each leg in or out.
D. The F112-LJ has a base gasket that must be
installed.Separatethegasketandinstallitwiththe
seamtotheback.Makesuretheangledsideofthe

WARNING
Do not alter or deform electrical plug in any way.
Altering the plug to fit into an outlet of different con-
figuration may cause fire, risk of electrical shock,
product damage and will void warranty.
H. Connect the power cord to the proper power
supply. The plug on the E112 is designed for
115VAC/20ampdutyandtheplugontheF112is
designed for 208-240VAC / 15 amp duty. Check

ratio. The auto fill kit is designed for use with Bag In Box
(BIB)concentratedsyrup.
Follow these instructions to properly install the brix pump
A. Route the clear tubing with the BIB connector to
the BIB. If there is excess tubing, trim it and
reconnect it to the BIB connector.

3.6 ASSEMBLY OF MACHINE
Toassemblethemachineparts,refertothefollowingsteps:
NOTE
Petrol Gel sanitary lubricant or equivalent must be
used when lubrication of parts is specified.
NOTE
The United States Department of Agriculture and

3.7 SANITIZING
Sanitizingmustbedoneafterthemachineiscleaned and
justbeforethehopperisfilledwithmix.Sanitizingthenight
beforeisnoteffective.However,youshouldalwaysclean
the machine and parts after each use.
TheUnitedStatesDepartmentofAgricultureandtheFood
and Drug Administration require that all cleaning and
sanitizingsolutionsusedwithfoodprocessingequipment
be certified for this use.
Whensanitizingthemachine, refertolocalsanitary regu-
lationsforapplicablecodesandrecommendedsanitizing
productsandprocedures.Thefrequencyofsanitizingmust
comply with local health regulations.
Mix sanitizer according to manufacturer’s instructions to
providea100partspermillion(ppm)strengthsolutionand
checkthesolutionwithchlorineteststrips.Mixsanitizerin
quantities of no less than 2 gallons (7.5 liters) of 90° to
110°F (32° to 43°C) water. Allow sanitizer to contact the
surfacestobe sanitizedfor5 minutes. Anysanitizermust
beusedonlyinaccordancewiththemanufacturer’sinstruc-
tions.
In general, sanitizing may be conducted as follows:
A. Prepare Stera-Sheen Green Label Sanitizer
accordingtomanufacturer’sinstructionstoprovide
a 100ppm strength solution. In the blue cleaner/
sanitizer bucket, mix 1 packet of sanitizer and 2
gallonsof coldwater. Checkthe chlorinecontent

B. Pour the sanitizing solution into the hopper.
C. Place theClean/Off/On switchto Clean.
D. Useasanitizedbarrelbrushtosanitizethehopper

F. PlacetheClean/Off/OnswitchOff.
G. Collecttheremainingsanitizerinacleancupand

C. Themachineisdesignedtodispensetheproduct
at a reasonable draw rate. If the machine is
overdrawn,theresultisawetproductoraproduct
that will not dispense at all. If this should occur,
allow the machine to run for approximately 30
secondsbeforedispensingadditionalproduct.
D. Do not operate the machine when the ADD MIX

isoperatingproperly.
NOTE
After 3 hours if the spigot is not opened, the ma-
chinewill go intodefrost mode.During this time,the
diagnosticlightwillbe lit andtheaugerwill runfor90
seconds every 7 minutes. Defrost mode maintains
consistency in the product and prevents large ice
crystalsfromforming.Toend defrostmode,turn the
Clean/Off/OnswitchOffthenbackOn.Defrostmode
will also end if the spigot is opened.
3.9 MIX INFORMATION
Mix can vary considerably from one manufacturer to an-
other.Differencesinthequantityandqualityofingredients
have a direct bearing on the finished frozen product. A
changeinmachineperformancethatcannotbeexplained
by a technical problem may be related to the mix.
Proper product serving temperature varies from one
manufacturer’s mix to another. Stackable slush mixes
providesatisfactoryproductfrom24°to28°F(-4°to-2°C).
When checking the temperature, stir the thermometer in
thefrozenproducttoobtainan accurate reading.
3.10 ROUTINE CLEANING
Toremovespilled ordried mix fromthe machine exterior,
wash in the direction of the finish with warm soapy water
andwipedry.Donotusehighlyabrasivematerialsasthey

3.11 PREVENTIVE MAINTENANCE
Stoelting recommends that a maintenance schedule be
followedtokeepthemachinecleanandoperatingproperly.
B. DAILY
1. The exterior should be kept clean at all times to
preserve the luster of the stainless steel. A mild

1. Disconnectthemachinefromthe power source.
2. Check drive belt for proper tension. Push belt in
withone finger, beltshould deflect about 3/8".
3. Lubricate condenser fan motor with S.A.E. 20
weightoil. Three tosix dropsare required.
4. Sanitize the autofill system following the steps
below:
AUTOFILLSANITIZING
A. Ifnecessary,disassemble,cleanandsanitizethe
machine. NOTE
If the machine does not require cleaning and sani-
tizing, turn it off and dispense enough product so
that the mix level in the hopper is below the long
probe. If the mix level is above the long probe, the
solenoidwillnot activate andthepumpwill notoper-
ate.
B. Prepare Stera-Sheen Green Label Sanitizer
accordingtomanufacturer’sinstructionstoprovide
a 100ppm strength solution. In the blue cleaner/
sanitizer bucket, mix 1 packet of sanitizer and 2
gallonsof coldwater. Checkthe chlorinecontent
with a test strip to ensure 100ppm strength.
C. Cut an adapter from an empty bag of syrup.
Connect the adapter to the BIB connector of the
syrup line. Put the BIB connector into the bucket
ofsanitizer. NOTE
If you do not have an emtpy bag of syrup, remove
the plug from the top of the BIB connector. Do not
losetheplug; it isneededfor proper operationofthe
BIB.
D. Hold the hopper cover over a bucket and set the
machine to clean. The solenoid will activate and
thebrix pumpwill pump sanitizer into thebucket.
NOTE
Thesolenoidwill onlyactivatewhen there isnot any
liquidtouching thelonger mix probe in the hopper.
E. After all the sanitizer has run through the pump,
turnthemachineoff.
F. DisconnectthebagadapterfromtheBIBconnector
(orreinsert the pluginto theconnector). Connect
the BIB connector to the syrup BIB.
