2.3 FREEZER INSTALLATION  
Installation of the freezer involves moving the freezer  
close to its permanent location, removing all crating,  
setting in place, assembling parts, and cleaning.  
A. Uncrate the freezer.  
Figure 5. Installing Trays and Inserts  
(F131 w/ blender shown)  
B. Accurate leveling is necessary for correct drainage  
of freezer barrel and to insure correct overrun. Place  
a spirit level on top of the freezer at each corner to  
check for level condition. If adjustment is necessary,  
level the freezer by turning the bottom part of each  
leg in or out. Then separate freezer base gasket and  
install with the seam to the back and the flat to the  
bottom.  
F. Connect the power cord. The plug is designed for  
208 or 230 volt/20 amp duty. Check the nameplate  
on your freezer for proper supply. The unit must be  
connected to a properly grounded receptacle. The  
electrical cord furnished as part of the freezer has a  
three prong grounding type plug (Fig. 6). The use of  
an extension cord is not recommended. If one must  
be used, use one with a wire size 12 gauge or heavier  
with a ground wire. Do not use an adaptor to get  
around grounding requirement.  
C. Air cooled freezers require correct ventilation. The  
right side of the freezer is the air intake and must  
have a 3" (7.5cm) clearance. Air discharges out of the  
left side of the unit and must have 3" (7.5cm) clear-  
ance. Do not obstruct the intake or discharge  
(Fig. 4).  
WARNING  
Do not alter or deform electrical plug in any way.  
Altering the plug to fit into an outlet of different  
configuration may cause fire, risk of electrical  
shock, product damage and will void the warranty.

Figure 10. 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. 11).  
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 AGRICUL-  
TURE AND THE FOOD AND DRUG ADMINISTRATION  
REQUIRETHATALLCLEANINGANDSANITIZINGSO-  
LUTIONS USED WITH FOOD PROCESSING EQUIP-  
MENT 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  
Figure 11. Sanitizing Procedure  
C. Place the OFF-ON toggle switch in the ON position  
while pressing the CLEAN switch. Check for leaks.  
(Fig. 12)  
manufacturer’s instructions.  
CAUTION  
Do not allow sanitizer to remain in contact with  
stainless steel freezer parts for prolonged  
periods. 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 with air inlet  
(long) tube toward the front of the freezer.  
(Fig. 10).  
Figure 12. Clean Control

3.4 FREEZE DOWN AND OPERATION  
This section covers the recommended operating proce-  
dures to be followed for the safe operation of the  
freezer.  
E. After five minutes, place a bucket under the spigot  
and open spigot to drain sanitizing solution. When  
solution has drained, press the CLEAN snap switch  
to stop the auger. Allow the freezer barrel to drain  
completely (Fig. 14).  
A. Sanitize just prior to use.  
B. Place the 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  
than2inches(5cm)fromthetopoftheairinlettubeon  
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.  
Figure 14. Spigot Opened and Solution Draining  
F. Fill a tall cup with sanitizing solution. Completely  
immerse the blender's agitator shaft in the sanitizer  
solution. Do not wipe dry (Fig. 15).  
F. Place the OFF-ON switch in the ON position, then  
press the PUSH TO FREEZE swtich until the freezer  
starts.  
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 green lens will illuminate. 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. 16).  
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).  
Figure 16. 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.  
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.  
3.6 REMOVING MIX FROM THE FREEZER  
To 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.17).  
J. Do not operate the freezer when the MIX LOW light  
is on 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 mode sometimes  
referred to as a sleep or energy conservation  
mode. When the freezer is not used, after a  
preset time, it will enter the standby mode and  
remain there until someone draws a product or  
pushes the push-to-freeze switch. In the  
standby mode, the freezer will keep the product  
below 45°F. Standby modes are not to be used

3.11 ASSEMBLY OF FREEZER  
To assemble the freezer parts, refer to the following  
steps:  
NOTE  
Petrol-Gel sanitary lubricant or equivalent must  
be used when lubrication of parts is specified.  
NOTE  
The United States Department ofAgriculture and  
Food and DrugAdministration require that  
lubricants used on food processing equipment  
be certified for this use. Use lubricants only in  
accordance with the manufacturer’s instruc-  
tions.  
Figure 25. Removing O-ring  
CAUTION  
Do not use any type of sharp object to remove O-  
rings. Using tools to remove O-rings may damage  
spigot and O-rings.  
A. Assemble all o-rings onto parts dry, without lubrica-  
tion. Then apply a thin film of sanitary lubrication to  
exposed surfaces of the O-rings. Apply a thin film  
of sanitary lubricant to metal part of rear seal. Also  
apply a thin film of sanitary lubricant inside the hole  
of the front of the auger.

3.12 ROUTINE CLEANING  
Important Differences Between Cleaning and  
To 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.  
Sanitizing  
CLEANINGvs.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.  
3.13PREVENTIVEMAINTENANCE  
It is recommended that a maintenance schedule be fol-  
lowed to keep the freezer clean and operating properly.  
CLEANING  
A. CleaningandSanitizingInformation  
·
·
Is the removal of soil materials from a surface.  
Is a prerequisite for effective sanitizing.  
Soft serve freezers require special consideration  
when it comes to food safety and proper cleaning  
and sanitizing.  
NOTE  
An UNCLEAN surface will harbor bacteria that can  
defy sanitizing efforts.  
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.  
Bacteria can develop and resist sanitizing efforts  
within a layer of soil material (milkstone). Thorough  
cleaningproceduresthatinvolvemilkstone  
removal are critical for operators of frozen  
dessertmachines.

Kills bacteria.  
Can be effective on clean surfaces only.  
DOES NOT clean or remove milkstone.  
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 difficult to remove and help  
attributetomilkstonebuild-up.  
NOTE  
Using a SANTITIZER on an unclean surface  
will not guarantee a clean and safe frozen  
dessert machine.  
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  
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.)  
contaminantsandeventuallydefysanitizing  
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-purposecleanersDONOTremove  
milkstone.) This can lead to high bacteria counts  
andafoodsafetydilemma.  
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).  
IT IS BEST TO CONTROL MILKSTONE ON A  
DAILY BASIS BEFORE IT CAN BECOME A  
SIGNIFICANTFOODSAFETYPROBLEM.  
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.  
16  
THE USE OF CHLORINE TEST STRIPS  
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.  
“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.  
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:  
The ideal concentration of chlorine needs to be 100  
ppm (as stated by the FDA).  
·
·
·
CLEANING – Thorough removal of all solids  
including butterfat and milk fat.  
NOTE  
Follow the directions on the container for proper  
concentration.  
MILKSTONE REMOVALCompleteremovalof  
milkstone.  
There are two main factors that contribute to falling  
chlorine concentrations in a sanitizing solution.  
SANITIZING – FDA-approved no rinse sanitizer  
for food contact surfaces.  
1. PRODUCT USE – As the chlorine in the  
solution is being used, chlorine concentrations  
fall.  
AdditionalInformation  
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:  
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  
1. PRODUCT SAFETY – Strong acids are  
dangerous chemicals and handling them  
requires safety  
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.  
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.  
CAUTION  
With proper daily use of STERA-SHEEN or it’s  
equivalent, there is no need for the use of a  
DELIMER.  
Do not use acidic cleansers, stron caustic com-  
pounds or abrasive materials to clean any part of  
the freezer exterior or plastic parts. Use of these  
types of cleaners will cause equipment damage.  
DO NOT USE BLEACH  
·
BLEACHHASABSOLUTELYNOCLEANING  
PROPERTIES.  
·
BLEACH IS CORROSIVE. It can and will  
damage components of the machine causing  
premature wear and metal corrosion.  
C. WEEKLY  
1. Check O-rings and rear seal for excessive  
wear and replace if necessary.  
GENERAL PURPOSE CLEANERS  
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.  
General purpose cleaners do not have the ability to  
remove milkstone. Milkstone will become a problem  
if not remedied with additional products and  
procedures.

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  
panelsremoved.  
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.  
Figure 29. 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.

minimum.  
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 29).  
Figure 30. Cleaning Condenser  
NOTE  
3. Visually inspect the condenser for dirt by shining a  
light through the coil from the back (inside) of the  
condenser.  
If the condenser is not kept clean, loss of refrig-  
eration efficiency will result; causing extended run  
time or soft product consistency.  
4. If the condenser is dirty, place a wet towel over the  
front (outside) of the condenser.  
Water-cooled condensers need an unrestricted supply  
of cold, clean water.
