I. Turn the flow control knob clockwise to the 2:00
position. A small amount of mix and remaining
sanitizer will drain from the machine.
J. Turn the flow control knob to the 1:00 position.
After a few minutes, a ribbon of product starts to
form.
K. Adjust the flow control knob until the product flow
fills the faceplate outlet and is at the desired
texture (Fig. 3-5). The flow control knob setting
will be different for each type of product.
NOTE
Adjustments take up to 1 minute before a notice-
able difference is seen in the product.
NOTE
A high-pitched noise from the freezing cylinder is an
indication that there is not enough mix entering the
barrel. Slowly turn the flow control knob clockwise
to increase the flow. It can take up to 1 minute for
the adjustment to stop the noise.
3.5 MIX INFORMATION
Mix can vary considerably from one manufacturer to an-
other. 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 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. When checking the tem-
perature, stir the thermometer in the frozen product to read
the true temperature.
Old mix or mix that has been stored at elevated tempera-
tures will produce poor-quality product with a bad taste and
unacceptable 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).
3.6 REMOVING MIX FROM MACHINE
To remove the mix from the machine, refer to the following
steps. Make sure the gate on the faceplate is open.
A. Press the PURGE/CLEAN button. The display
will read PURGE.
B. Press and hold the PURGE/CLEAN button for 3
seconds. The display will read CLEAN and a 20
minute timer will start.
C. Open the flow control valve fully by turning the flow
control knob clockwise until the pointer is near the
12:00 position.
D. After the hopper and freezing cylinder have
drained, place the Main Freezer Power OFF-ON
switch in the OFF position.
3.7 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. Place a container under the slide of the faceplate.
Fill the hopper with 2 gallons (7.5 liters) of tap
water.
B. Place the Main Freezer Power OFF-ON switch in
the ON position. Press the PURGE/CLEAN button.
The display will read PURGE.
C. Press and hold the PURGE/CLEAN button for 3
seconds. The display will read CLEAN and a 20
minute timer will start
D. When the water has drained, place the switch in
the OFF position. Allow the freezing cylinder to
drain completely.
E. Prepare detergent water by mixing 2 oz. of
Palmolive detergent or equivalent in 2 gallons of
90° to 110°F (32° to 43°C) water. Repeat steps A
through D using the detergent solution.
3.8 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 perfor-
mance and a quality product. Frequency of cleaning must
comply with local health regulations.
