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

(SF144 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.

3.4 FREEZE DOWN AND OPERATION

This section covers the recommended operating proce-

dures to be followed for the safe operation of the

freezer.

A. Sanitize just prior to use.

B. Place the FREEZING CYLINDER OFF-ON switch in

the OFF position.

Figure 12. Sanitizing Hopper

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.

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. 13).

D. Fill hopper with approximately 3 gallons (11.4 liters)

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.

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.

H. For normal dispensing, move the spigot handle fully

open (Fig. 15).

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 15. Dispensing Product

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.

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.

3.6 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.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-to-

freeze 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 sani-

tizing. Frequency of cleaning and sanitizing is

determined by Federal, State, and local regula-

tory agencies.

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.

Soil Materials Associated with Frozen Dessert

Machines

SANITIZING

Kills bacteria.

Can be effective on clean surfaces only.

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.

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.

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 REMOVAL–Completeremovalof

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.

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 28. Condenser and Filter

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).

Figure 29. 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.
