G. Dispense Rate Adjuster

The dispense rate adjustor limits the opening

of the spigot and is located under the header

panel, to the immediate right of the spigot handle.

Turning the knob counterclockwise will decrease

the dispense rate.

3.3 ASSEMBLY OF MACHINE

All parts should be cleaned, sanitized and allowed to air
dry before assembling.

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 the o-rings onto the spigot dry , without

lubrication. Then apply a thin fi lm of sanitary
lubrication to the exposed surfaces of the o-rings.
Also apply a thin fi lm of sanitary lubricant to the
inside and outside of the front auger support
bushing.

B. Put the rear seal o-ring onto the back of the

auger and generously lubricate with Petrol-Gel.
Assemble the rear seal onto the auger with the
large end to the rear.

3.4 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 certifi ed 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.

CAUTION

Do not allow sanitizer to remain in contact with
stainless steel parts for prolonged periods. Pro­longed contact of sanitizer with machine may cause
corrosion of stainless steel parts.

In general, sanitizing may be conducted as follows:
A. Prepare Stera-Sheen Green Label Sanitizer

or equivalent according to manufacturer’s

instructions to provide a 100 ppm strength solution.

Mix the sanitizer in quantities of no less than

2 gallons of 90° to 110°F (32° to 43°C) water.

Check the strength of the sanitizing solution. Use

a chlorine test strip and color chart to make sure

the solution has 100 ppm. Any sanitizer must be

used only in accordance with the manufacturer’s

instructions.
B. Place the mix inlet regulator into hopper.
C. Insert the bushing into the bottom of the hopper

agitator and put the agitator onto the shaft in

the hopper. Align the guide hole in the shaft and

agitator. Place the drive cap onto the agitator so

that the pin fi ts into the guide hole.
D. Pour the sanitizing solution into the hopper and

wait until the freezing cylinder is fi lled. Check for

leaks.
E. While the freezing cylinder fi lls, clean the sides

of the hopper, the agitator , the mix inlet regulator

and the underside of the hopper cover using a

soft bristle brush dipped in the sanitizing solution.
F. Place the switch in the CLEAN position.
G. After fi ve minutes, place a bucket under the spigot

and open the spigot to drain the sanitizing solution.

Leave a small amount of the sanitizing solution

in the freezing cylinder. Place the switch in the

OFF (middle) position.
H. Collect the remaining sanitizing solution in a cup

and test the chlorine contents with a new test strip.

A reading of 100 ppm or more is acceptable.
If the reading is less than 100 ppm, sanitize the

machine again.
If the reading is less than 100 ppm after sanitizing

the second time, disassemble and wash the

machine again.

Operators Manual #513675 7 F212 Model Machines

3.5 FREEZE DOWN AND OPERATION

This section covers the recommended operating proce­dures for the safe operation of the machine.

A. Sanitize just prior to use.
B. Place the switch in the OFF (middle) position.
C. Fill the hopper with pre-chilled liquid mix (40°F

or 4°C) .

NOTE

Do not overfi ll the hopper. Mix level must be below
the air inlet tube on the mix inlet regulator.

D. Open spigot and drain a small amount of mix to

remove any remaining sanitizer.

E. Allow the freezing cylinder to fi ll at least halfway .

Place the switch in the ON position.

NOTE

After the drive motor starts, there is a 3 or 4 second
delay before the compressor starts.

F. After 8 to 12 minutes the product will be at

consistency and will be ready to serve. Freeze
down time may vary depending on mix type and
ambient temperatures.

G. To dispense, pull the spigot handle down to open

the spigot.

H. The machine is designed to dispense the product

at a reasonable draw rate. If the machine is
overdrawn, the result is a liquid product. If this
should occur, allow the machine adequate time
to recover before dispensing additional product.

I. Do not operate the machine when the ADD MIX

light is on. Refi ll the hopper immediately.

3.6 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. Shake mixes generally
provide satisfactory product from 24° to 28°F (-4° to -2°C).

When checking the temperature, stir the thermometer in
the frozen product to obtain an accurate reading.

Old mix or mix that has been stored at elevated tempera­tures will produce poor-quality product with a bad taste
and unacceptable appearance. T o retard bacteria growth
in dairy based mixes, the best storage temperature range
is between 33° to 38°F (0.5° to 3.3°C).

Some shake mixes tend to foam more than others. If foam
appears in the hopper, skim off with a sanitized utensil
and discard.

3.7 REMOVING MIX FROM MACHINE

To remove the mix from the machine, refer to the follow­ing steps:

A. Pull the mix inlet regulator straight up and remove

it from the hopper.
B. Place the switch in the CLEAN position to rotate

the auger.
C. Drain the mix by opening the spigot. A container

should be placed under the spigot to collect the

mix.
D. Place the switch in the OFF (middle) position.

3.8 CLEANING THE MACHINE

NOTE

The frequency of cleaning the machine and ma­chine parts must comply with local health regula­tions.

After the mix has been removed from the machine, the
machine must be cleaned. To clean the machine, refer
to the following steps:

A. Close the spigot and fi ll the hopper with 2 gallons

(8 liters) of tap water.
B. Place the switch in the CLEAN position. The auger

will start to rotate.
C. Allow the water to agitate for approximately 30

seconds.
D. Open the spigot to drain the water. Remember to

place a container under the spigot to catch the

water. When the water has drained, place the

switch in the OFF (middle) position. Allow the

freezing cylinder to drain completely.
E. Rinse the machine with tap water again.
F . Wash the hopper with a clean barrel brush dipped

in cleaning solution.

3.9 DISASSEMBLY OF MACHINE 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. Frequency of cleaning
must comply with the local health regulations.

Operators Manual #513675 9 F212 Model Machines

3.13 PREVENTIVE MAINTENANCE

A. DAILY

1. The exterior should be kept clean at all times to

preserve the luster of the stainless steel. A mild

alkaline cleaner is recommended. Use a soft cloth

or sponge to apply the cleaner.

B. WEEKLY

1. Check o-rings and rear seal for excessive wear

and replace if necessary.

2. Remove the drip tray and drain tray. Clean the

areaa around the tray and the front of the machine

with a soap solution.

C. QUARTERLY
Air Cooled & Hopper Condenser

The condensers are 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 could increase the hopper
temperature, lower the capacity of the system or damage
the compressor.

The condensers must be kept clean of dirt and grease.
The machine must have 3” (7.6 cm) ventilation on both
sides. Make sure the machine is not pulling over 100° F
(37° C) air from other equipment in the area.

The condensers and condenser fi lters require periodic
cleaning. To clean, refer to the following procedures.

A. Disconnect power to the machine
B. Remove the Phillips head screws from the right

side panel, and remove the panel.
C. To remove a condenser fi lter, grasp the top and

pull off. Visually inspect the fi lters for dirt. If a

fi lter is dirty, shake or brush excess dirt off the

fi lter and wash it in warm, soapy water. Once it

is clean, rinse it thoroughly in warm, clear water

and shake dry, taking care not to damage the

fi lter in any way.

Water Cooled

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. Make sure the machine is receiving an
unrestricted supply of cold, clean water.

E. SEMI-ANNUALLY

1. Disconnect the machine from the power source.

2. Use a Burroughs Belt Tension Gauge to set the
tension for the drive belt. Set the belt tension to
45-55 lbs.

3. Lubricate the condenser fan motor with S.A.E.
20 weight oil. Three to six drops are required.

3.14 EXTENDED STORAGE

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

A. Place the CLEAN-OFF-ON switch in the OFF

(middle) position.

B. Disconnect (unplug) from the electrical supply

source.

C. Clean all parts that come in contact with mix

thoroughly with a warm water cleaning solution
Rinse in clean water and dry parts. Do not sanitize.

NOTE

Do not let the cleaning solution stand in the hop­per or in the freezing cylinder during the shutdown
