is lit during serve mode. During freeze down, the
green LED is not lit. When product consistency
approaches 75% in the freezing cylinder, the
green LED fl ashes. The amber LED is lit during all
other modes. In the event of an error or when the
freezing cylinder is off, both LEDs will alternatively
fl ash.
NOTE
If the machine shuts off, and alternating green and
amber lights are fl ashing, the machine is in an error
condition. If the LCD displays an error, turn the Main
Freezer Power OFF-ON switch to the OFF position,
correct the problem (Refer to Troubleshooting in

3.3 IMPORTANT INFORMATION REGARDING
CLEANING AND SANITIZING
Soft serve and shake machines require special consideration when it comes to food safety and proper cleaning
and sanitizing.
The following information specifi cally covers issues for
cleaning and sanitizing frozen dessert machines. This
information is meant to supplement a comprehensive
food safety program.
Soil Materials Associated with Frozen Dessert Machines
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
diffi cult to remove and help attribute to milkstone buildup.
MILKSTONE – Is a white/gray fi lm that forms on equip-
ment and utensils that are exposed to dairy products.
These fi lms will accumulate slowly on surfaces because of
ineffective cleaning, use of hard water , or both. Milkstone
is usually a porous deposit, which will harbor microbial
contaminants and eventually defy sanitizing efforts.
Once milkstone has formed, it is very diffi cult 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.
IT IS BEST T O CONTROL MILKSTONE ON A DAIL Y BASIS BEFORE IT CAN BECOME A SIGNIFICANT FOOD
SAFETY PROBLEM.
In addition to food safety, milkstone can cause premature wear to machine parts, which can add to costs for
replacement parts or possibly more expensive repairs
if worn machine parts are not replaced once they have
become excessively worn.
Important Differences Between Cleaning and Sanitizing
CLEANING vs. SANITIZING
It is important to distinguish between cleaning and sanitiz-
ing. Although these terms may sound synonymous, they
are not. BOTH are required for adequate food safety and
proper machine maintenance.
CLEANING
• Is the removal of soil materials from a surface.
• Is a prerequisite for effective sanitizing.
NOTE
An UNCLEAN surface will harbor bacteria that can
defy sanitizing efforts.
Bacteria can develop and resist sanitizing efforts within
a layer of soil material (milkstone). Thorough cleaning
procedures that involve milkstone removal are critical for
operators of frozen dessert machines.
SANITIZING
• Kills bacteria.
• Can be effective on clean surfaces only.
NOTE
Using a SANITIZER on an unclean surface will not
guarantee a clean and safe frozen dessert machine.
Proper Daily Maintenance:
The Only Way to Assure Food Safety and Product Quality
Proper daily maintenance can involve a wide variety
of products and procedures. Overall, the products and
procedures fall into three separate categories. (Please
note that this is a brief overview intended for informational
purposes only.)
1. CLEANING – This involves draining mix from
the freezing cylinder and rinsing the machine
with water. Next, a cleaner is run through the
machine. Then, the machine is disassembled
and removable parts are taken to the sink for
cleaning.
2. MILKSTONE REMOVAL – Since most cleaners
do not have the ability to remove milkstone, the
use of a delimer becomes necessary. Although
this procedure may not be needed on a daily
basis, it will usually follow the cleaning procedure.
It requires letting a delimer solution soak in the
machine for an extended period. Individual parts
are also soaked in a deliming solution for an
extended period of time (more about delimers in
Additional Information).
3. SANITIZING – After the machine has been
cleaned and contains no milkstone, the machine
is reassembled. Then a FDA-approved sanitizing
solution is run through the machine to kill bacteria.
The machine is then ready for food preparation.
As a recommended cleaner and sanitizer for your frozen
dessert machine, STERA-SHEEN has proven to be one
of the best daily maintenance products for:
• CLEANING – Thorough removal of all solids
including butterfat and milk fat.
• MILKSTONE REMOV AL – Complete removal of
milkstone.
• SANITIZING – FDA-approved no rinse sanitizer
for food contact surfaces.
Additional Information
THE USE OF DELIMERS
A delimer is a strong acid that has the ability to dissolve
milkstone. This type of chemical may become necessary
once high levels of milkstone have developed. While these
products are very effective for removing HIGH levels of
milkstone, they are not ideal for two reasons:
1. PRODUCT SAFETY – Strong acids are dangerous
chemicals. Carefully follow safety instructions
provided with delimer products.
Owner’s Manual #513532-5 Rev.1 7 E111I/F111I Model Machines
2. MACHINE DAMAGE – Strong acids will attack
metal and rubber causing premature wear of
parts. The use of a delimer needs to be closely
monitored to avoid damage to machine surfaces
and parts.
With proper daily use of STERA-SHEEN or its equivalent,
there is no need for the use of a DELIMER.
DO NOT USE BLEACH
• BLEACH HAS ABSOLUTELY NO CLEANING
PROPERTIES.
• BLEACH IS CORROSIVE. It will damage
components of the machine causing premature
wear and metal corrosion.
GENERAL PURPOSE CLEANERS
General purpose cleaners do not have the ability to re-
move milkstone. Milkstone will become a problem if not
remedied with additional products and procedures.
THE USE OF CHLORINE TEST STRIPS
“Test strips” are used to determine concentrations of
active chlorine in sanitizing solutions. To use the strips,
tear off a small portion and submerge it into the sanitizing
solution. Then, compare the color change to the color key
on the side of the test strip dispenser to determine the
approximate chlorine concentration.
The ideal concentration of chlorine needs to be 100 ppm
(as stated by the FDA).
NOTE
Follow the directions on the container for proper
concentration.
Two main factors contribute to falling chlorine concentrations in a sanitizing solution.
1. PRODUCT USE – As the chlorine in the solution
is being used, chlorine concentrations fall.
2. TIME – As time passes, small amounts of chlorine
“evaporate” from the solution. (That is why you
can smell it.)
Sanitizing solutions should not be allowed to fall below
100 ppm chlorine. New solutions should be mixed once
old solutions become ineffective.
3.4 DISASSEMBLY OF PARTS
Inspection for worn or broken parts should be made each
time the machine is disassembled. All worn or broken
parts should be replaced to ensure safety to both the
operator and the customer and to maintain good machine
performance and a quality product. Check the wear line on
the auger fl ights on a regular basis (Fig. 3-3) and replace
as needed. Frequency of cleaning must comply with the
local health regulations.
Wear Line
Figure 3-3 Auger Flight Wear
T o disassemble the machine, refer to the following steps:
A. Remove hopper cover and drain tray.
B. Remove the mix inlet regulator from the hopper
by pulling straight up.
C. Remove the front door by turning the circular
knobs and then pulling the front door off the studs.
D. Remove the rosette cap from the front door. Push
the spigot body through the bottom of the front
door and remove.
E. Remove the front auger support and bushing (Fig.

H. Remove the rear seal.
I. Wipe socket lubricant from the drive end (rear)
of the auger with a cloth or paper towel.
J. Remove all o-rings from parts by fi rst wiping off
the lubricant using a clean paper towel. Then
squeeze the o-ring upward with a dry cloth (Fig.
3-6). When a loop is formed, roll out of the o-ring
groove.
3.5 CLEANING DISASSEMBLED PARTS
Disassembled parts require complete cleaning, sanitizing and air drying before assembling. Local and state
health codes will dictate the procedure required. Some
state health codes require a four sink process (pre-wash,
wash, rinse, sanitize, air dry), while others require a three
sink process (without the pre-wash step). The following
procedures are a general guideline only. Consult your
local and state health codes for the procedures required
in your location.
A. Disassemble all parts. (Refer to Section 3.4 for
the disassembly of machine parts.)
B. Place all front door and auger parts in clean 90° to
1 10°F (32°C to 43°C) water and wash thoroughly
(four sink procedure only).
C. Place all parts in 90° to 110°F (32°C to 43°C) mild
detergent water and wash thoroughly.
D. Rinse all parts with clean 90° to 110°F (32°C to
43°C) water.
E. Sanitize all machine parts following procedures
outlined below.
3.6 SANITIZING PARTS
A. Use a sanitizer, mixed according to manufacturer’s
instructions, to provide a 100 parts per million
strength solution. Mix sanitizer in quantities of
no less than 2 gallons of 90° to 110°F (32°C to
43°C) water. Any sanitizer must be used only in
accordance with the manufacturer’s instructions.
B. Place all parts in the sanitizing solution for 5
minutes, then remove and let air dry completely
before assembling in machine.
3.7 CLEANING THE MACHINE
CAUTION
Do not use any type of sharp object to remove the
o-rings.
Figure 3-6 Removing O-Ring
Owner’s Manual #513532-5 Rev.1 9 E111I/F111I Model Machines
The exterior should be kept clean at all times to preserve
the luster of the stainless steel. A high grade of stainless
steel has been used on the machine to ease cleanup. To
remove spilled or dried mix, wash the exterior with 90° to
110°F (32°C to 43°C) soapy water and wipe dry.
Do not use highly abrasive materials, as they will mar the
fi nish. A mild alkaline cleaner is recommended. Use a soft
cloth or sponge to apply the cleaner. For best results, wipe
with the grain of the steel.
A. Clean the rear seal surface from inside of the
freezing cylinder.
B. Using sanitizing solution and the large barrel
brush provided, sanitize the freezing cylinder by
dipping the brush in the sanitizing solution and
brushing the inside of the freezing cylinder.
C. Remove the drip tray by pulling from the front
panel. Clean and replace the drip tray.
3.8 ASSEMBLING MACHINE
T o assemble the machine parts, refer to the following steps:
NOTE
Petrol Gel sanitary lubricant or equivalent must be
used when lubrication of parts is specifi ed.
NOTE
The United States Department of Agriculture and
the Food and Drug Administration require that lubricants used on food processing equipment be certifi ed for this use. Use lubricants only in accordance
with the manufacturer’s instructions.
A. Assemble all o-rings onto parts dry, without
lubrication. Then apply a thin fi lm of sanitary
lubrication to exposed surfaces of the o-rings.
Apply a thin fi lm of sanitary lubricant to metal
part of rear seal. Also apply a thin fi lm of sanitary
lubricant inside and outside of the front auger
support bushing.
B. Assemble the rear seal onto the auger with the
large end to the rear. Be sure the o-ring is in place
before installing the rear seal.
C. Lubricate the auger drive (rear) with a small
amount of white socket lubricant. A small container
of socket lubricant is shipped with the machine.
D. Screw the springs onto the studs in plastic
fl ights. Springs must be screwed into the fl ights
completely to provide proper compression (Fig.
3-7).
Figure 3-8 Front Door Parts
F . Install the remaining plastic fl ights, push the auger
into the machine barrel and rotate slowly until the
auger engages the drive shaft.
G. Install the bushing and auger support into the front

E. Install the two plastic fl ights onto rear of the auger
and insert part way into machine barrel.
Owner’s Manual #513532-5 Rev.1 10 E111I/F111I Model Machines
3.9 SANITIZING
Sanitizing must be done after the machine is cleaned and
just before the hopper is fi lled with mix. Sanitizing the night
before is not effective. However , you should always clean
the machine 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 PROCESSING EQUIPMENT BE CERTIFIED FOR THIS USE.
When sanitizing the machine, 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
90° to 1 10°F (32° to 43°C) water. Allow sanitizer to contact

3.12 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 17°F to 24°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 .

when troubleshooting.
DISPLAY READINGS
Following are the readings available under the DISPLA Y
menu:
Hopper (°F)
The temperature of the hopper is constantly
monitored by the IntelliTec control.
Cycles (count)
This reading counts down the number of cycles
in the current “Serve Mode”. The starting value
is dependant upon the Cycles setting on the
IntelliTec control.
°F and amps
The suction line temperature on the freezing
cylinder and the drive motor amps are available
on the same screen to assist with setup and
troubleshooting.
Aux. Temp (°F)
This reading provides the ambient temperature
around the IntelliTec control.
Supply V (VAC)
A calculated input voltage is recorded.
ERROR CODE READINGS
The following details are recorded under the ERRCODES
menu for each of the last 25 error codes received:
Err1 (hours)
A numerical count of the last 25 error codes is
recorded. When the 26th error has occurred
the earliest error code is erased. A timer also
begins when an error occurs. The timer records
the number of hours since the error occurred. If
power to the machine is interrupted, the timer will
stop until power has been restored.
°F and amps
The suction gas temperature on the freezing
cylinder and the drive motor amps are recorded
at the time of the error.
Aux. Temp (°F)
Ambient temperature of the IntelliTec control is
recorded at the time of the error.
Str (°F)
The storage temperature is recorded at the time
of the error.
VAC and Mode
A calculated input voltage and mode at which
the error occurred are recorded. Following are
descriptions of each mode:

10 Freezing cycle is shut down
11 Door safety switch triggered
12 High pressure cutout
Owner’s Manual #513632-5 Rev.1 17 E111I/F111I Model Machines
Up Time (hours)
This value is a record of the total time the machine
has been in service. If power is interrupted, the
timer will stop until power is restored. This timer
does not reset.
RUN STATISTICS
In addition to dynamic readings and recorded
error code details, the IntelliTec control records
rolling averages of run statistics. Following are the
readings available under the RUNST ATS menu:
On Times (sec)
The control records the time of each freezing
cycle and provides a rolling average.
Off Times (sec)
The control records the time between freezing
cycles and provides a rolling average.
Brl. Min (°F)
The lowest average barrel temperature is
recorded.
Brl. Max (°F)
The highest average barrel temperature is
recorded.
Stor Min (°F)
The lowest average hopper temperature is
recorded.
Stor Max (°F)
The highest average hopper temperature is
recorded.
Power On (hrs)
This value is a record of the time the machine
has been in service. If power is interrupted, the
timer will reset.
4.6 ADJUSTMENTS (SERVICE PERSONNEL
ONLY)
The following adjustments directly affect product consistency and length of time in “Serve Mode”. The default
settings have been created using a 5% milkfat soft serve
mix and provide optimal product consistency while prolonging product life.
CutOut (amps)
It is recommended to change the CutOut value
at initial startup and when changing mix types.
Adjustments to this setting directly affect the
length of the freezing cycle which changes product
consistency. To properly set the CutOut value,
refer to Section 3.
Cut In T (°F)
After the consistency value has been determined,
the Cut In T value can be adjusted. The Cut In
T is the temperature of the refrigerant gas in the
evaporator. Changing this setting changes the
temperature at which the freezing cycle starts. This
value along with the CutOut value determines the
range of temperatures (or “temperature window”)
of the product. Decreasing the temperature
decreases the temperature window and, under
normal use, increases the amount of freezing
cycles. This creates a greater chance of product
breakdown by stirring the product often. Increasing
the Cut In T increases the temperature window
which decreases freezing cycles and increases
the chance of heat shock within the product.
Cycles (count)
This setting determines the number of freezing
cycles during “Serve Mode”. Increasing the value
will increase the total time in “Serve Mode”. Factory
default is 16 cycles. This results in “Serve Mode”
lasting about 2 to 2-1/2 hours without the PUSH
TO FREEZE button being pressed or a spigot
handle being pulled. If the PUSH TO FREEZE
button is pressed or the spigot handle is pulled at
any time during “Serve Mode”, the Cycles count
will reset.
4.7 OTHER SETTINGS (SERVICE
PERSONNEL ONLY)
Changing any setting on the IntelliTec control will alter
machine operation and affect the product temperature,
consistency , or life. Refer to the IntelliT ec Control System
Settings sheet located in the information pouch behind
the header panel of the machine. If any of the following
settings on the IntelliTec control differ from the System
Settings sheet, it is recommended to revert those settings
to factory defaults.
Stir On (sec)
Adjustments to this setting affect the amount of
time the auger rotates in the stir cycle. The stir
cycle occurs in “Serve Mode”, “Standby Mode”,
and “Sleep 2 Mode”.
Stir Off (sec)
Adjustments to this setting affect the time between
stir cycles. The stir cycle occurs in “Serve Mode”,
“Standby Mode”, and “Sleep 2 Mode”.
On Time (sec)
Increasing this value will increase the length of the
freezing cycle during “Standby Mode” and result
in a decrease of average product temperature in
the barrel.
Owner’s Manual #513632-5 Rev.1 18 E111I/F111I Model Machines
Off Time (sec)
Increasing this value will increase the time between
freezing cycles in “Standby Mode” and result in
an increase of product temperature in the barrel.
Stb Time (sec)
This setting determines the total amount of time
in “Standby Mode”.
Sl1DrvOn (sec)
Adjustments to this setting affect the amount of
time the auger rotates in the stir cycle. This stir
cycle only occurs in “Sleep 1 Mode”.
Sl1DrOff (sec)
Adjustments to this setting affect the time between
stir cycles. The stir cycle only occurs in “Sleep 1
Mode”.
Sl2CutIn (°F)
Changing this setting affects the temperature at
which the freezing cycle starts in “Sleep 2 Mode”.
Sl2CtOut (°F)
Changing this setting affects the temperature at
which the freezing cycle stops in “Sleep 2 Mode”.
DftOffTm (sec)
In “Serve Mode”, this value determines the
maximum time without a freezing cycle. If this
value is met, a freezing cycle will start. In the event
of a freezing cylinder temperature sensor failure,
this value affects the amount of time between
freezing cycles during “Serve Mode”.
Refriger
This setting changes how the control handles
the storage refrigeration cycle. The setting for
the E111 & F111 is 1 Hopper.
HprCutIn (°F)
This setting determines the temperature at which
the hopper refrigeration cycle starts. This setting
is only available on the left control.
HprCtOut (°F)
This setting determines the temperature at which
the hopper refrigeration cycle stops. This setting
is only available on the left control..
Hpr Off (min)
If the temperature sensor in the hopper fails,
this setting determines the time between hopper
refrigeration cycles. This setting is only available
on the left control..

4.9 CONDENSER CLEANING
The air-cooled condenser is a copper tube and aluminum
fi n type. Condensing is totally dependent upon airfl ow .
A plugged condenser fi lter, 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” (7.5 cm) of ventilation on the right and left sides 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 condenser and condenser fi lter require periodic clean-
ing. To clean, refer to the following procedures.
1. Remove the right side panel and the rear panel.
2. T o remove the condenser fi lter, grasp the top and
pull off. Visually inspect for dirt. If the fi lter is dirty,
shake or brush excess dirt off the fi lter and wash
in warm, soapy water. Once the fi lter is clean rinse
thoroughly in warm, clear water and shake dry,
taking care not to damage the fi lter in any way.
3. Visually inspect the condenser for dirt by shining
a light through the coil from the back (inside) of
the condenser.
4. If the condenser is dirty, place a wet towel over
the outside of the condenser.
5. Using compressed air or a CO2 tank, blow out
the dirt from the inside of the condenser. Most of
the dirt will cling to the wet towel.
NOTE
If the condenser is not kept clean, refrigeration effi ciency will be lost.
4.10 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.
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.
Inspect for worn or broken parts and replace
as necessary. Check the wear line on the auger
fl ights and replace as needed.
B. Monthly checks
Check the condenser fi lter for dirt. (Refer to section
4.9).
C. Quarterly Checks
Check drive belts for wear and tighten belts if
necessary. (Refer to section 4.8)
4.11 EXTENDED STORAGE
Refer to the following steps for storage of the machine
over any long period of shutdown time:
A. Clean thoroughly with warm detergent all parts
that come in contact with mix. Rinse in clear water
and dry all parts. Do not sanitize.
NOTE
Do not let cleaning solution stand in machine barrel
or mix pump 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. Place the Main Freezer Power OFF/ON switch
in the OFF position.
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 will be displayed on the control
panel. Each error code directs you to the system location
of the malfunction.
ERROR CODE MALFUNCTION
1 Soft
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 Auxiliary Sensor
11 Low Temperature
12 Left Hopper Sensor
13 Right Hopper Sensor
To return the machine to normal operation, any error
causing condition must be corrected and the Freezing
Cylinder Off-On switch must be placed in the Off position
and back in the On position before the affected side of
the machine will return to normal operation.
5.2 TROUBLESHOOTING
Error Code 1 - Soft Error
The Soft Error (E1) is an internal control board error
that is logged for future analysis. The refrigeration
is never stopped and the machine will continue
to operate normally.
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. Place the Main
Power OFF/ON switch in the OFF position, wait
until the product in the freezing cylinder thaws
and return the switch to the ON position. Follow
the instructions in Section 3 to reduce the product
consistency by a few levels. 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 or if the product does not reach proper
temperature in “Sleep 2 Mode”. This error is
generally caused by very low mix levels in the
machine’s 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 T ime Error may
indicate that airfl ow within the machine has
reduced or stopped. Check the sides and top
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 will display 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". The control will attempt
to restart itself after 5 minutes. The display will
then fl ash and read Restart. To clear the Clean
Error, turn the Freezing Cylinder Off-On switch
Off and back On. After restarting the machine,
a refrigeration cycle will begin. This protects the
product in case the clean button was pressed by
mistake.
Owner’s Manual #513532-5 Rev.1 21 E111I/F111I Model Machines
Error Code 5 - Freezing Cylinder Sensor
The Freezing Cylinder Sensor Error (E5) indicates
a failure of the barrel sensor or that the sensor
is out of range. If the control panel displays an
