use the Technician passcode and go to the Basic
Settings menu. Adjust the CutIn Consistency Offset higher to increase the consistency or lower to
decrease the consistency. Make adjustments in
increments of 5 for best results.
G. The machine dispenses product at a reasonable
draw rate. If the machine is overdrawn, the result
is a soft product or a product that will not dispense
at all. If this occurs, allow the machine to run for
approximately 30 seconds before dispensing more
product. A dispense rate adjustor is located under
the header panel, to the immediate right of the
spigot handle. Turning the knob counterclockwise
decreases the dispense rate.
H. Do not operate the machine when the MIX
LOW message is displayed. Refi ll the hopper
immediately.
NOTE
After a preset number of freezing cycles in Serve
mode, the control enters sleep mode and remains
there until someone draws product or presses the
PUSH TO FREEZE button. In the sleep mode, the
machine keeps the product below 41°F (5°C). Sleep
modes do not take the place of cleaning and sanitizing. Federal, State, and local regulatory agencies
determine frequency of cleaning and sanitizing.

3.10 MIX INFORMATION
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 fi nished frozen product. A change
in machine performance that cannot be explained by a
technical problem may be related to the mix.
Proper product serving temperature varies from one
manufacturer’s mix to another. Mixes should provide a
satisfactory product in the 18°F to 20°F range. Diet and
low-carb mixes typically freeze to proper consistency at
higher temperatures.
When checking the temperature, stir the thermometer in
the frozen product to get an accurate reading.
Old mix, or mix that has been stored at too high a temperature, can result in a fi nished product that is unsatisfactory.
To retard bacteria growth in dairy based mixes, the best
storage temperature range is between 33° to 38°F (0.5°
to 3.3° C).

MAINTENANCE AND ADJUSTMENTS
4.9 DRIVE BELT TENSION ADJUSTMENT
To check belt tension, refer to Figure 4-4 and follow the
steps below:
WARNING
Hazardous voltage
Make sure the machine is off when disassembling
for servicing. The machine must be disconnected
from electrical supply before removing any access
panel. Failure to disconnect power before servicing
could result in death or serious injury.
A. Remove the back panel.
B. Use a Burroughs Belt Tension Gauge to set the
tension for the drive belt. Set the belt tension to
50-55 lbs.
C. If an adjustment is necessary , loosen the four nuts
on the motor mounting plate and slide the plate
up or down to adjust belt tension. Then retighten
the nuts.
D. Using a straightedge, check that the drive motor
pulley is aligned with the speed reducer pulley.
Align the pulley if necessary.
NOTE
Belt life will be increased if new drive belts are
tightened after two or three weeks of operation.
4.10 CONDENSER CLEANING
The O231 has two condensers. An air-cooled or watercooled condenser and a condensing unit for the hopper.
The air-cooled condenser (and hopper condenser) is
a copper tube and aluminum fi n type. Condensing is
totally dependent upon airfl ow. A plugged condenser, or
restrictions in the louvered panel will restrict airfl ow. This
will lower the capacity of the system and damage the
compressor. The condenser must be kept clean of dirt
and grease. The machine must have a minimum of 3”
(7.6 cm) of ventilation at the sides and back of the unit
for free fl ow of air. Make sure the machine is not pulling
over 100° F (37° C) air from other equipment in the area.
The water-cooled condenser is a tube and shell type. The
condenser needs a cool, clean supply of water to properly
cool the machine, inlet and discharge lines must be 3/8”
I.D. minimum.
The air-cooled condenser and hopper condenser require periodic cleaning. To clean, refer to the following
procedures.
A. Visually inspect the condenser for dirt.
B. If the condenser is dirty, place a wet towel over
the condenser.
C. Using compressed air or CO2 tank, blow out the
dirt from the back of the condenser. Most of the
dirt will cling to the wet towel.
D. An alternative method is to clean with a
condenser brush and vacuum.
NOTE
If the condenser is not kept clean, refrigeration effi ciency will be lost.
4.11 PREVENTATIVE MAINTENANCE
It is recommended that a preventative maintenance
schedule be followed to keep the machine clean and
operating properly . The following steps are suggested as
a preventative maintenance guide.
Loosen four nuts to
Loosen four nuts to

The United States department of agriculture and the food
and drug administration require that lubricants used in
food zones be certifi ed for this use. Use lubricants only
in accordance with the manufacturer’s instructions.
A. Daily checks
Check for any unusual noise or condition and
repair immediately.
Page 20
B. Monthly checks
Check the condenser for dirt and clean if
necessary.
C. Quarterly Checks
Check drive belts for wear and tighten belts if
necessary.
4.12 EXTENDED STORAGE
Refer to the following steps for storage of the machine
over any long period of shutdown time:
A. Clean all the parts that come in contact with mix
thoroughly with a warm detergent water. Rinse
in clear water and dry all parts. Do not sanitize.
NOTE
Do not let cleaning solution stand in the freezing
cylinder or hopper during the shutdown period.
B. Remove, disassemble, and clean the front door,
and auger shaft. Leave disassembled during the
shutdown period.
C. Place the auger fl ights and auger support bushing
in a plastic bag with a moist paper towel. This will
prevent them from becoming brittle if exposed to
dry air over an extended period of time (over 30
days).
D. For water-cooled machines that are left in unheated
buildings, or buildings subject to freezing, the water
must be shut off and disconnected. Disconnect
the water inlet fi tting. The fi tting is located at the
rear of the machine. Run the compressor for 2 - 3
minutes to open water valve (the front door must
be attached for the compressor to run). Blow
out all water through water inlet. Drain the water
supply line coming to the machine. Disconnect
the water outlet fi tting.
E. Press the Main Power On/Off button to turn the
machine off.
F. Disconnect the machine from the source of
electrical supply.

SECTION 5
TROUBLESHOOTING
5.1 ERROR CODES
When the machine experiences a problem, one of the
following error codes is displayed on the control panel.
Each error code directs you to the system location of the
malfunction.
ERROR CODE MALFUNCTION
2* High Torque
3* Run Time
4 Clean
5 Freezing Cylinder Sensor
6 Hopper Sensor (single hopper machines)
7* Drive Motor
8 Cab Sensor
9 High Pressure Cutout
10 Ambient Sensor
11* Prime (cab units only)
12 Left Hopper Sensor
13 Right Hopper Sensor
21* Spigot Open Time
* After this error occurs, the machine goes into Sleep 3
mode where the compressor runs on timers and the drive
motor does not run. The timers keep the product at a safe
temperature until the machine can get serviced.
To return the machine to normal operation, any error
causing condition must be corrected and the power to
the affected freezing cylinder must be cycled. Turn the
power to the freezing cylinder off then back on using the
On/Off button of the affected freezing cylinder.
5.2 TROUBLESHOOTING - ERROR CODES
Error Code 2 - High Torque
If the control panel displays a High Torque Error
(E2), the controller has sensed that the drive motor
is running at a high load for 10 or more seconds.
This may be due to the product consistency
adjustment being set too high. Press the On/Off
button for the cylinder to turn it off, wait until the
product in the freezing cylinder thaws and then
turn the cylinder back on. If the error persists,
contact your Authorized Stoelting Distributor for
further assistance.
Error Code 3 - Run Time
The Run Time Error (E3) occurs when the
compressor runs continuously for an extended
period. This error is generally caused by very
low mix levels in the hopper or from product
breakdown. Another common cause results from
a restriction preventing mix from entering the
freezing cylinder. Check the mix in the hopper.
If the level mix is low, add mix. If there is a
possibility that the mix has broken down, clean
and sanitize the machine and replace the mix
with fresh product.
Ice crystals in the hopper can clog the mix inlet
system and prevent mix from entering the freezing
cylinder. Thoroughly thaw mix per manufacturer’s
recommendations. T o check for ice crystals, pour
a small amount of product from the mix container
through a clean and sanitized sieve or strainer.
If ice crystals are in the mix, check temperature
of the walk-in cooler where the mix is stored.
In air cooled machines, the Run Time Error
may indicate that airfl ow within the machine
has reduced or stopped. Check the sides of the
machine for anything that would restrict airfl ow.
If the error persists after attempting to clear it,
contact your Authorized Stoelting Distributor for
further assistance.
Error Code 4 - Clean
If the machine is left in the Clean Mode for more
than 20 minutes, the control panel displys a
Clean Error (E4). This condition does not refl ect a
problem with the machine itself. The Clean Error
has been programmed into the controller as a
safeguard to protect the machine from potential
damage caused by the machine being accidentally
left in "Clean Mode". To clear the Clean Error,
press the On/Off button for the cylinder to turn if
off then back on.
Operators Manual #513717 15 O231-I2F Model Machines

Error Code 5 - Freezing Cylinder Sensor
The Freezing Cylinder Sensor Error (E5) indicates
a failure of the sensor or that the sensor is out
of range. If the control panel displays an E5,
press the On/Off button for the cylinder to turn
if off then back on. If the error persists, contact
your Authorized Stoelting Distributor for further
assistance.
NOTE
When the machine encounters a Freezing Cylinder
Sensor Error, the machine continues to run using
preset timers. This mode allows the operator to
continue serving product until the machine can be
serviced.
Error Code 6 - Hopper Sensor (single hopper machines)
The Hopper Sensor Error (E6) will not occur on
the machine.
Error Code 7 - Drive Motor
If the control panel displays a Drive Motor Error
(E7), the control does not sense current coming
from the drive motor. Press the On/Off button
for the cylinder to turn if off then back on. If the
error persists, contact your Authorized Stoelting
Distributor for further assistance.
Error Code 8 - Cab Sensor
A Cab Sensor Error (E8) will not occur on the
machine.
Error Code 9 - High Pressure Cutout
High Pressure Cutout Errors (E9) are usually
caused by a dirty or ineffi cient condenser. If the
control panel displays an E9 on an air cooled
machine, check for proper air clearance around
the machine. If there is an E9 on a water cooled
machine check for proper fl ow from the water
supply or kinks in the hoses.
If the error persists, contact your Authorized
Stoelting Distributor for further assistance.
Error Code 10 - Auxiliary Sensor
An Auxiliary Temperature Sensor Error (E10)
occurs if the temperature sensor on the control
board fails. Press the On/Off button for the cylinder
to turn if off then back on. If the error persists,
contact your Authorized Stoelting Distributor for
further assistance
Error Code 11 - Prime Error
The Prime Error (E11) will not occur on the
machine.
Error Code 12 - Left Hopper Sensor
The Left Hopper Sensor Error (E12) indicates
a failure of the hopper sensor or if the sensor is
out of range. If the control panel displays an E12,
press the On/Off button for the cylinder to turn
if off then back on. If the error persists, contact
your Authorized Stoelting Distributor for further
assistance.
