A Few Words About Safety
Safety Information
Read and understand the entire manual before
operating or maintaining Stoelting equipment.
Safety Alert Symbol:
This symbol Indicates danger, warning or caution.
Attention is required in order to avoid serious personal
injury. The message that follows the symbol contains
important information about safety.
This Owner's 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 definitions are provided to assist the reader.
Signal Word:
Signal words are distinctive words used throughout
this manual that alert the reader to the existence and
relative degree of a hazard.
The purpose of safety symbols is to attract your
attention 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.
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
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.
The signal word “CAUTION” indicates a potentially
hazardous situation, which, if not avoided, may result
in minor or moderate injury and equipment/property
damage.
CAUTION
The signal word “CAUTION” not preceded by the safety
alert symbol indicates a potentially hazardous situa-
tion, which, if not avoided, may result in equipment/
property damage.
NOTICE
The signal word “NOTICE” indicates information or
procedures that relate directly or indirectly to the

longed contact of sanitizer with freezer may cause
corrosion of stainless steel parts.
NOTE
In general, sanitizing may be conducted as follows:
Failure to refill hopper immediately may result in op-
erational problems.
A.
Prepare Stera-Sheen Green Label Sanitizer or
equivalentaccordingtomanufacturer’sinstructions
to provide a 100ppm strength solution. Mix the
sanitizer in quantities of no less than 2 gallons of
90° to 110°F (32° to 43°C) water. Any sanitizer

Sanitizingmustbedoneafterthefreezeriscleanedandjust
before the hopper is filled with mix. Sanitizing the night
before is not effective. However, you should always clean
the freezer and parts after each use.
The United States Department of Agriculture and
the Food and Drug Administration require that all
cleaning and sanitizing solutions used with food pro-
cessing equipment be certified for this use.

When checking the temperature, stir the thermometer in
the frozen product to obtain an accurate reading.
If using a shake mix, install the mix inlet regulator
into hopper (Refer to Figure 3-3). If using a slush
mix, the mix inlet regulator is not required.

tureswillproducepoor-qualityproductwithabadtasteand

dairy based mixes, the best storage temperature range is
between 36° to 40°F (2.2° to 4.4°C).

Place the switch in the OFF (middle) position.
NOTE
Make sure the mix inlet regulator is in place before
adding shake mixes. This is not necessary for slush
mixes.
3.6 REMOVING MIX FROM FREEZER
To remove the mix from the freezer, refer to the following
steps:
C.
D.
Pour approximately 1/2 gallon of fully thawed mix
into the hopper. Open spigot and drain a small
amountofmixtoremoveanyremainingsanitizer.
A.
If removing shake mix, pull the mix inlet regulator
straight up and remove it from the hopper.
B.
Place the switch in the CLEAN position to rotate
the auger. Allow the mix to agitate in freezing
cylinder until the mix has become liquid, about 5
minutes.
Fill hopper with pre-chilled (40°F or 4°C) mix.
NOTE
Do not overfill the hopper. Mix level must not be
higher than the air inlet tube on the mix inlet regula-
tor.
C.
D.
Drain the liquid mix by opening the spigot. A
container should be placed under the spigot to
collect the liquid mix.
E.
Place the switch in the ON position.
Place the switch in the OFF (middle) position.
NOTE
After the drive motor starts, there is a 3 second de-
lay before the compressor starts.
3.7 CLEANING THE FREEZER

Proper Daily Maintenance: The Only Way to Assure
Food Safety and Product Quality
MILKFAT/BUTTERFAT – As components of ice-cream/
frozen custard mix, these soils will accumulate on the
interior surfaces of the machine and its parts. Fats are
difficulttoremoveandhelpattributetomilkstonebuild-up.
Proper daily maintenance can involve a wide variety of

CLEANING – This involves draining mix from the
freezing cylinder and rinsing the machine with
water.Next,acleanerisrunthroughthemachine.
Then,themachineisdisassembledandremovable
parts are taken to the sink for cleaning.
Once milkstone has formed, it is very difficult to remove.
Without using the correct product and procedure, it is
nearly impossible to remove a thick layer of milkstone.
(NOTE: general-purpose cleaners DO NOT remove
milkstone.) This can lead to high bacteria counts and a
food safety dilemma.

MILKSTONE REMOVAL – Since almost all

In addition to food safety, milkstone can cause premature
wear to machine parts which can add to costs for replace-
ment parts or possibly more expensive repairs if worn
machine parts are not replaced once they have become
excessivelyworn.

SANITIZING–Afterthemachinehasbeencleaned
and contains no milkstone, the machine is
reassembled. Then a FDA-approved sanitizing

The machine is then ready for food preparation.
