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.

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 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.

completely (Fig. 13).

Figure 13. Spigot Opened and Solution Draining

B. Place the FREEZING CYLINDER OFF-ON switch in

the OFF position.

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.

NOTE

Do not overfill the hopper. Mix level must not be higher
than 2 inches (5 cm) from the top of the air inlet tube on
the mix inlet regulator.

E. The freezer barrel will automatically fill until it is

about 1/2 full. If freezer barrel does not fill, check for
obstruction in the mix inlet regulator. If freezer barrel
fills over 1/2 full, indicated by low overrun, check for
leaks at the mix inlet regulator O-ring or check if
the mix inlet regulator was installed correctly or that
the freezer is level.

F . Place the FREEZING CYLINDER OFF-ON switch in

the ON position, then press the PUSH TO FREEZE
swtich until the freezer starts.

F . To sanitize SF144 models with the blender, fill a tall

cup with sanitizing solution. Completely immerse the

blender's agitator shaft in the sanitizer solution. Do

not wipe dry (Fig. 14).

NOTE

After the auger drive motor starts, there is a 3
second delay before the compressor starts.

10

G. After about 6 to 10 minutes the freezer will shut off

and the "SERVE" message will display on the LCD

panel. 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.
H. For normal dispensing, move the spigot handle fully

open (Fig. 15).

Figure 15. Dispensing Product

I. 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 dispens-

ing 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 . Spigot Rate Adjusters are

located under the Header Panel, to the immediate

right of each Spigot Handle. Turning the Spigot Rate

Adjuster counterclockwise will decrease the

dispense rate.

3.5 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 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 such as
yogurt to Vitari, 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 of f with a sanitized
utensil and discard. Periodically , stir the mix in the
hopper with a sanitized utensil.

3.6 REMOVING MIX FROM THE FREEZER

T o remove the mix from the freezer , refer to the following
steps:

A. Remove the mix inlet regulator from the hopper by

pulling straight up (Fig.16).

J. Do not operate the freezer when the MIX LOW

message is displayed or with less than 1-3/4" (4.4

cm) of mix in the hopper. Refill the hopper

immediately.

NOTE

The freezer has a standby and sleep mode. When
the freezer is not used, after a preset number of
freezing cycles, it will enter the standby mode
(followed by sleep mode) and remain there until
someone draws a product or pushes the push-to­freeze switch. In the sleep mode, the freezer will
keep the product below 45°F (7.2°C). Sleep modes
are not to be used in place of cleaning and sani­tizing. Frequency of cleaning and sanitizing is
determined by Federal, State, and local regula­tory agencies.

B. Place the FREEZING CYLINDER OFF-ON

switch in the ON position and push the CLEAN switch

to rotate the auger . Allow the mix to agitate in the

freezer barrel until the mix has become a liquid,

about 5 minutes.
C. Drain the liquid mix by opening the spigot. A bucket

or container should be placed under the spigot to

catch the liquid mix (Fig. 17).
D. Place the Freezing Cylinder OFF-ON switch in the

OFF position.

CAUTION

Hazardous Moving Parts

Revolving blender agitator shaft can grab and cause
injury. Remove watches and jewelry prior to

3.12 ROUTINE CLEANING

T o remove spilled or dried mix from the freezer exterior,
simply wash in the direction of the finish with warm
soapy water and wipe dry . Do not use highly abrasive
materials as they will mar the finish.

3.13 PREVENTIVE MAINTENANCE

It is recommended that a maintenance schedule be fol­lowed to keep the freezer clean and operating properly.

A. Cleaning and Sanitizing Information

Soft serve freezers require special consideration
when it comes to food safety and proper cleaning
and sanitizing.

The following information has been compiled by
Purdy Products Company, makers of Stera-Sheen
Green Label Cleaner/Sanitizer and specifically
covers issues for cleaning and sanitizing frozen
dessert machines. This information is meant to
supplement a comprehensive food safety program.

Important Differences Between Cleaning and
Sanitizing

CLEANING vs. SANITIZING

It is important to distinguish between cleaning and
sanitizing. 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.

Soil Materials Associated with Frozen Dessert
Machines

MILKFAT/BUTTERFAT – As components of ice­cream/frozen custard mix, these soils will
accumulate on the interior surfaces of the machine
and its parts. Fats are difficult to remove and help
attribute to milkstone build-up.

MILKSTONE – Is a white/gray film that forms on
equipment and utensils that come in contact with
dairy products. These films 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 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.

IT IS BEST TO CONTROL MILKSTONE ON A
DAILY 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.

SANITIZING

· Kills bacteria.

· Can be effective on clean surfaces only.

· DOES NOT clean or remove milkstone.

NOTE

Using a SANTITIZER 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 freezer barrel 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 almost all
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 of time. Individual parts are also soaked
in a deliming solution for an extended period of
time (more about delimers in Additional
Information).

16

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 REMOVAL – Complete removal of
milkstone.

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.

· 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 and handling them
requires safety

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 it’s
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 can and will
damage components of the machine causing
premature wear and metal corrosion.

GENERAL PURPOSE CLEANERS

General purpose cleaners do not have the ability to
remove milkstone. Milkstone will become a problem
if not remedied with additional products and
procedures.

There are two main factors that 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

B. DAILY

1. The exterior should be kept clean at all times to
preserve the lustre of the stainless steel. A mild
alkaline cleaner is recommended. Use a soft
cloth or sponge to apply the cleaner.

CAUTION

Do not use acidic cleansers, stron caustic com­pounds or abrasive materials to clean any part of
the freezer exterior or plastic parts. Use of these
types of cleaners will cause equipment damage.

C. WEEKLY

1. Check O-rings and rear seal for excessive
wear and replace if necessary.

2. Remove the drip tray by gently lifting up to
disengage from the support and pulling out.
Clean behind the drip tray and front of the
freezer with a soap solution.

17

D. QUARTERLY

WARNING

High voltage will shock, burn or cause death. Turn
off and lock out main power disconnect before
servicing. Do not operate machine with cabinet
panels removed.

The air-cooled condenser is a copper tube and aluminum
fin type. Condensing is totally dependent upon airflow. A
plugged condenser filter, condenser, or restrictions in the
louvered panel will restrict airflow. This will lower the
capacity of the system and damage the compressor.

The condenser must be kept clean of dirt and grease. The
freezer must have a minimum of 3” (7.5 cm) of ventilation
on the right and left sides of the unit for free flow of air
(Figure 29). Make sure the freezer 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 freezer, inlet and discharge lines must be 3/8” I.D.
minimum.

Figure 28. Condenser and Filter

5. Using a vacuum, carefully clean the condenser coil
from the inside and outside of the freezer. A stiff
bristled brush may help in releasing debris from
between the condenser coils (Figure 29).

The condenser and condenser filter require periodic
cleaning. To clean, refer to the following procedures.

1. Remove the Phillips head screw from the bottom of
the right side panel, and then slide the panels down
and out.

2. To remove the condenser filter, grasp the top and pull
off. Visually inspect for dirt. If the filter is dirty, shake
or brush excess dirt off the filter and wash in warm,
soapy water. Once the filter is clean rinse thoroughly
in warm, clear water and shake dry, taking care not
to damage the filter in any way (Figure 28).

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
front (outside) of the condenser.

Figure 29. Cleaning Condenser

NOTE

If the condenser is not kept clean, loss of refrig­eration efficiency will result; causing extended run
time or soft product consistency.

Water-cooled condensers need an unrestricted supply
of cold, clean water.

18

3.14 EXTENDED STORAGE

Refer to the following steps for storage of the freezer
over any long period of shutdown time:

A. Turn both FREEZING CYLINDER OFF-ON switches

to the OFF position.

B. Disconnect (unplug) from the electrical supply

source.

C. Clean thoroughly with a warm water detergent all

parts that come in contact with the mix. Rinse in
clear water and dry all parts. Do not sanitize.

NOTE

Do not let the cleaning solution stand in the
hopper or in the freezer barrel during the
shutdown period.

D. Remove, disassemble and clean the front door, mix

inlet regulator and auger parts. Place the auger
flights in a plastic bag with a moist paper towel to
prevent them from becoming brittle.

E. On water cooled freezers, shut off and disconnect

water supply at rear of freezer; run compressor for
2-3 minutes to open water valve, and blow out all
water first through inlet then outlet line, using air or
carbon dioxide.

3.15 PRODUCT CONSISTENCY ADJUSTMENT

The freezer's control system monitors the consistency
(firmness) of the product (mix) in each freezing cylinder.
The program module senses the consistency of the
product and shuts off the drive motor and refrigeration
system when the pre-programmed consistency is reached.
The control panels on the front of the freezer allow the
operator to adjust each freezing cylinder to create the
desired product consistency.

A. Place the FREEZING CYLINDER OFF/ON switch in the

ON position.

B. Press the SET button on the Control Panel once.

Fine Adj will appear on the LCD screen (Fig. 30).

C. Press the up arrow button

(⇑) (⇑)

SECTION 4

TROUBLESHOOTING

4.1 ERROR CODES

The following error condition codes will display on the
control panel when the freezer is experiencing a problem.
The error condition code directs you to the system location
of the malfunction.

ERROR CODE MALFUNCTION
01 Program Board
02 High Torque Error
03 Extended Run Time Error
04 Clean Error
05 Freezing Cylinder Sensor
07 Drive Motor Current
09 High Pressure Cutout
12 Left Hopper Sensor Error
13 Right Hopper Sensor Error

Any error causing condition must be corrected, then the
power turned off, and back on before the freezer will return
to normal operation.

4.2 UNDERSTANDING ERROR CODES

ERROR CONDITION CODE 01
If the control panel displays a program board error (Error
Code 01), place the Freezing Cylinder Off-On Switch in the
Off position, wait 10 seconds, and return the switch to the
On position. If the Control Panel still displays the error
condition code, call your Authorized Stoelting Distributor
for further assistance.

ERROR CONDITION CODE 02
If the control panel displays a high torque error (Error Code

02), the controller has sensed that the product in the

freezing cylinder has reached 125% of set consistency for
10 or more seconds. This condition may be caused if the
product consistency adjustment has been set too high. To
remedy this condition, place the Freezing Cylinder Off-On
Switch in the Off position, wait until the product in the
freezing cylinder has had adequate time to thaw to a
reasonably soft consistency, and return the switch to the
On position. Follow the Product Consistency Adjustment
procedures at the begining of this section and reduce the
Fine Adjustment value by a few points. If the Control Panel
still displays the error condition code, call your Authorized
Stoelting Distributor for further assistance.

ERROR CONDITION CODE 03
Extended run time errors (Error Code 03) are often times
caused by the mix running too low in the freezer’s hopper,
or if a restriction is preventing the mix from entering the
freezing cylinder. Check the mix level on the affected
freezing cylinder. If the level mix is low, add mix. Look for
ice crystals in the liquid mix in the hopper. Ice crystals can
clog the mix inlet regulator, and prevent mix from entering
the freezing cylinder. If you find ice crystals in the mix,
check the temperature of the walk-in cooler where the mix
is stored.
Excessive compressor run time may also occur if the
condenser filter is dirty, or if the condenser is obstructed.
Check around the sides of the freezer, to be sure nothing
has been placed near the condenser vents. A minimum of
3" clearance is required.
After the cause of the problem is found and remedied,
place the Freezing Cylinder Off-On Switch in the Off
position, wait 10 seconds, and return the switch to the On
position. If the Control Panel still displays the error
condition code, call your Authorized Stoelting Distributor
for further assistance.

ERROR CONDITION CODE 04
If the freezer is left in the Clean Mode for more than 20
minutes, the control panel will display a Clean Error (Error

04). This condition does not reflect a problem with the
freezer itself. The Clean Error has been programmed into
the controller as a safeguard to protect the freezer from
potential damage caused by the freezer being accidentally
left in the clean mode. To remedy the Clean Error, place
the Freezing Cylinder Off-On Switch in the Off position,
wait 10 seconds, and return the switch to the On position.
If the Control Panel still displays the error condition code,
call your Authorized Stoelting Distributor for further assis­tance.

ERROR CONDITION CODE 05
If the control panel displays a Freezing Cylinder Sensor
error (Error Code 05), place the Freezing Cylinder Off-On
Switch in the Off position, wait 10 seconds, and return the
switch to the On position. If the Control Panel still displays
the error condition code, call your Authorized Stoelting
Distributor for further assistance.

NOTE

When the freezer encounters a Freezing Cylinder Sensor
Error, the freezer will automatically be switched to run on
pre-configured timing cycles. This mode will allow you to
continue serving product until the freezer can be serviced.

21

ERROR CONDITION CODE 07
If the control panel displays a Drive Motor Current error
(Error Code 07), place the Freezing Cylinder Off-On
Switch in the Off position, wait 10 seconds, and return the
switch to the On position. If the Control Panel still displays
the error condition code, call your Authorized Stoelting
Distributor for further assistance.

ERROR CONDITION CODE 09 (water cooled models only)
Error 09 conditions are usually caused by insufficient
cooling at the freezer's condenser. If the control panel
displays a High Pressure Cutout error (Error Code 09),
turn the freezer power off. Press the High Pressure Cutout
Reset Switch located on the upper, left hand corner of the
left side panel. There is a round, black boot covering the
reset switch. Pressing in the center of the boot will reset
the switch.
Check for proper waterflow through the condenser coil.
After the cause of the error is determined and corrected,
place the Freezing Cylinder switch to the On position. If the
Control Panel still displays the error condition code, call
your Authorized Stoelting Distributor for further assis­tance.

ERROR CONDITION CODE 12
If the control panel displays a left hopper sensor error
(Error Code 12), place the Freezing Cylinder Off-On
Switch in the Off position, wait 10 seconds, and return the
switch to the On position. If the Control Panel still displays
the error condition code, call your Authorized Stoelting
Distributor for further assistance.

ERROR CONDITION CODE 13
If the control panel displays a right hopper sensor error
(Error Code 13), place the Freezing Cylinder Off-On
Switch in the Off position, wait 10 seconds, and return the
switch to the On position. If the Control Panel still displays
the error condition code, call your Authorized Stoelting
Distributor for further assistance.

ALTERNATING FLASHING CONTROL PANEL LIGHTS
When the right Freezing Cylinder OFF/ON switch is

placed in the ON position and the left Freezing Cylinder
OFF/ON switch is left in the OFF position, the green and
amber control panel lights will flash in alternating se­quence and the message "Frz Cyl Hprs Of" will display
on the LCD panel. This indicates that the right freezing
cylinder is receiving power, but the hoppers are not be­ing refrigerated. Placing the left Freezing Cylinder OFF/
ON switch in the ON position will return the left freezing
cylinder to the SLEEP mode, and keep the hoppers re­frigerated.
