it is going to have.
F. Disconnect electrical cord for maintenance.
Never attempt to repair or perform maintenance on
the freezer until the main electrical power has been
disconnected.
G.Do not operate under unsafe operating condi
tions. Never operate the freezer if unusual or exces
sive noise or vibration occurs.
3.2 OPERA TION CONTROLS AND INDICA TORS
Before operating the freezer, it is required that the
operator know the function of each operating control.
Refer to Figure 6 for the location of the operating controls
on the freezer.
WARNING
THE CLEAN-OFF-ON SWITCH MUST BE PLACED IN
THE OFF POSITION WHEN DISASSEMBLING FOR
CLEANING OR SERVICING. THE FREEZER MUST BE
DISCONNECTED FROM ELECTRICAL SUPPLY BEFORE
REMOVING ANY ACCESS PANEL.
A. CLEAN-OFF-ON SWITCH
The CLEAN-OFF-ON switch is a three-position toggle
switch used to control the operation of the refrigeration system and auger. When the switch is placed in
the CLEAN position, the refrigeration system will be
off and the auger will rotate for cleaning.
When the switch is placed in the OFF position, the
refrigeration system and auger will not operate.
B. NIGHT-SERVE SWITCH
The NIGHT-SERVE switch is a two position toggle
switch. When the switch is placed in the SERVE
position, the auger and compressor will run until the
product is ready to serve. When the switch is in the
NIGHT position, the auger and compressor will run to
maintain a product in liquid form at a safe temperature.
C. SPIGOT SWITCH
The SPIGOT switch will automatically actuate the
auger drive and refrigeration systems when the spigot
is opened to dispense product. When the spigot is
closed, the drive motor and compressor will remain
“on” until the product in the barrel is ready to serve
again.
D. DRIVE MOTOR OVERLOAD
The internal drive motor overload will trip if the drive
motor is overloaded. It will reset after approximately
10-12 minutes. If the drive motor continues to trip,
refer to Section 4-Troubleshooting.
E. MIX LEVEL INDICATOR
The MIX LEVEL indicator has a red float designed to
alert the operator to a low mix condition. When the
red indicator is not visible, there is approximately one
gallon of mix left in the hopper. Refill hopper immediately.
NOTE
Failure to immediately refill hopper may result in operational problems.
F. DOOR INTERLOCK SWITCH
When the door is securely fastened, the freezer will
operate normally. When the door is removed, the drive
and compressor will not run.
3.3 SANITIZING
Sanitizing must be done after the freezer is clean and
just before the hopper is filled with mix. Sanitizing the
night before is not effective. However, you should
always clean the freezer and parts after using it.
WARNING
THE UNITED STATES DEPARTMENT OF AGRICULTURE AND THE FOOD AND DRUG ADMINISTRATION
REQUIRE THAT ALL CLEANING AND SANITIZING SOLUTIONS USED WITH FOOD PROCESSING EQUIPMENT BE CERTIFIED FOR THIS USE.
When the switch is placed in the ON position, the
refrigeration system and auger will operate automati-
cally. The switch should be placed in the ON position
for normal operation.

Page 15
When sanitizing the freezer, refer to local sanitary
regulations for applicable codes and recommended
sanitizing products and procedures. The frequency of
sanitizing must comply with local health regulations.
Mix sanitizer according to manufacturer’s instructions to
provide a 100 parts per million strength solution. Mix
sanitizer in quantities of no less than 2 gallons (7.5
liters) of 120°F of water. Allow sanitizer to contact the
surfaces to be sanitized for 5 minutes. Any sanitizer
must be used only in accordance with the
manufacturer’s instructions.
CAUTION
PROLONGED CONTACT OF SANITIZER WITH FREEZER
MAY CAUSE CORROSION OF STAINLESS STEEL
PARTS.
In general, sanitizing may be conducted as follows:
A. Push the mix inlet regulator into hopper (Fig. 7).
Figure 7. Mix Inlet Regulator
B. Prepare 2 gallons (7.5 liters) of sanitizing solution
following manufacturer’s instructions. Pour into
hopper with mix inlet regulator in place (Fig.8).
Figure 8. Sanitizing Procedure
Figure 9. Sanitizing Hopper
C. Place the CLEAN-OFF-ON toggle switch in the
CLEAN position. Check for leaks.
D. Clean sides of hopper, mix inlet regulator and under-
side of hopper cover using a sanitized soft bristle
brush dipped in the sanitizing solution(Fig.9).
E. After five minutes, place a bucket under the spigot
and open spigot to drain sanitizing solution. Allow the
freezer barrel to drain completely (Fig.10). When
solution has drained, place the CLEAN-OFF-ON
switch in the OFF position.
Figure 10. Open Spigot and Drain Solution

Page 16
3.4 FREEZE DOWN AND OPERA TION
This section covers the recommended operating procedures to be followed for the safe operation of the freezer.
A. Sanitize just prior to use.
B. Place the CLEAN-OFF-ON switch in the OFF posi-
tion.
C. With spigots open, pour approximately 1 gallon (3.8
liters) of mix into the hopper. Allow the mix to flush
out about 8 ounces (0.23 liters) of sanitizing solution
and liquid mix. Close the spigot.
D. Fill hopper with approximately 3 gallons (11.4 liters) of
prechilled (40°F or 4°C) mix. The freezer barrel will
automatically fill until it is about half full.
CAUTION
DO NOT OVERFILL THE HOPPER. MIX LEVEL MUST
NOT BE HIGHER THAN 2 INCHES (5 CM) FROM THE TOP
OF TH E AIR INLET TUBE ON THE MIX INLET REGULATOR.
E. Place the NIGHT-SERVE switch in the SERVE
position.
F. Place the CLEAN-OFF-ON switch in the ON position.
After about 6 to 10 minutes the freezer will shut off
and the product will be ready to serve. Freeze down
time may be longer for some frozen diet dessert
mixes. High ambient temperatures may extend freeze
down time.
G. To dispense product, move the spigot handle up
(Fig.11). Close spigot completely after dispensing.
The freezer will run for a minimum of 50 seconds after
the spigot is closed.
H. The freezer is designed to dispense the product at a
reasonable draw rate. If the freezer is overdrawn, the
result is a soft product or a product that will not
dispense at all. If this should occur, allow the freezer
to run for approximately 30 seconds before dispensing additional product. After a while the operator will
sense or feel when the freezer is beginning to fall
behind, and will slow down on the rate of draw so as
not to exceed the capacity.
I. Do not operate the freezer if the mix level indicator
shows a low-mix condition (red indicator no longer
visible). A minimum of 1 gallon of mix should be kept
in the hopper at all times.
Figure 11. Dispensing Product
3.5 MIX INFORMA TION
Mix can vary considerably from one manufacturer to
another. Differences in the amount of butterfat content
and quantity and quality of other ingredients have a direct
bearing on the finished frozen product. A change in
freezer performance that cannot be explained by a
technical problem may be related to the mix.
When changing from one type of mix to another, you
may have to change the mix inlet regulator and/or control
settings. Please call your distributor for further information.
Proper product serving temperature varies from one
manufacturer’s mix to another. Mixes should provide a
satisfactory product in the 18° to 20°F (-7° to -6°C)
range.
When checking the temperature, stir the thermometer in
the frozen product to read the true temperature.
Mix does not improve with age. Old mix, or mix that has
been stored at too high a temperature, can result in a
finished product that is less than satisfactory in taste
and appearance. To retard bacteria growth in dairy based
mixes, the best storage temperature range is between
36° to 40°F (2.2° to 4.4°C).
Some products tend to foam more than others. If excess
foam should occur, skim the foam off with a sanitized
utensil and discard. Periodically stir the mix in the
hopper with a sanitized utensil.
J. For night operation, place the NIGHT-SERVE switch
to the NIGHT position. The product in the barrels will
return to a liquid state in approximately 4 hours.

WARRANTY
SOFT SERVE / SHAKE FREEZERS
1. Scope:
Stoelting, LLC warrants to the first user (the “Buyer”) that the freezer cylinders, hoppers, compressors,
drive motors, speed reducers, auger and auger flights of Stoelting soft serve / shake freezers will be free
from defects in materials and workmanship under normal use and proper maintenance appearing within
five (5) years, and that all other components of such equipment manufactured by Stoelting will be free from
defects in material and workmanship under normal use and proper maintenance appearing within twelve
(12) months after the date that such equipment is originally installed.
2. Disclaimer of Other Warranties:
THIS WARRANTY IS EXCLUSIVE; AND STOELTING HEREBY DISCLAIMS ANY IMPLIED
WARRANTY OF MERCHANTABILITY OR FITNESS FOR PARTICULAR PURPOSE.
3. Remedies:
Stoelting’s sole obligations, and Buyer’s sole remedies, for any breach of this warranty shall be the repair
or (at Stoelting’s option) replacement of the affected component at Stoelting’s plant in Kiel, Wisconsin, or
(again, at Stoelting’s option) refund of the purchase price of the affected equipment, and, during the first
twelve (12) months of the warranty period, deinstallation/reinstallation of the affected component from/into
the equipment. Those obligations/remedies are subject to the conditions that Buyer (a) signs and returns
to Stoelting, upon installation, the Checklist/Warranty Registration Card for the affected equipment, (b)
gives Stoelting prompt written notice of any claimed breach of warranty within the applicable warranty
period, and (c) delivers the affected equipment to Stoelting or its designated service location, in its original
packaging/crating, also within that period. Buyer shall bear the cost and risk of shipping to and from
Stoelting’s plant or designated service location.
4. Exclusions and Limitations:
This warranty does not extend to parts, sometimes called “wear parts”, which are generally expected to
deteriorate and to require replacement as equipment is used, including as examples but not intended to
be limited to o-rings, auger seals, auger support bushings and drive belts. All such parts are sold
AS IS.
Further, Stoelting shall not be responsible to provide any remedy under this warranty with respect to any
component that fails by reason of negligence, abnormal use, misuse or abuse, use with parts or equipment
not manufactured or supplied by Stoelting, or damage in transit.
THE REMEDIES SET FORTH IN THIS WARRANTY SHALL BE THE SOLE LIABILITY
STOELTING AND THE EXCLUSIVE REMEDY OF BUYER WITH RESPECT TO EQUIPMENT
SUPPLIED BY STOELTING; AND IN NO EVENT SHALL STOELTING BE LIABLE FOR ANY
INCIDENTAL OR CONSEQUENTIAL DAMAGES, WHETHER FOR BREACH OF
WARRANTY OR OTHER CONTRACT BREACH, NEGLIGENCE OR OTHER TORT, OR ON
ANY STRICT LIABILITY THEORY.
