3.11 NORMAL FREEZE DOWN AND
OPERATION
Refer to the following procedures to operate both freez-
ing cylinders.
A. Sanitize immediately before use.
B. Make sure the display shows the freezing cylinders
are off. If they are not, Press the On/Off Left or
On/Off right button to turn it off.
C. Fill the storage container in the cab with at least
2.5 gallons of mix.
D. Attach the mix inlet probe to the container and
place the container in the refrigerated cab.
E. Press the Pump button to turn the pump on.
F. Place a container under the spigot and open it to
allow the mix to fl ush out about 8 ounces (0.23
liters) of sanitizing solution and liquid mix. Close
the spigot.
G. Open the air bleed valve on the front door by
pressing and holding. Hold the valve open until
the mix level in the freezing cylinder is 1/2” from
the air bleed valve.
H. Press the On/Off button for the cylinder.
I. Press the PUSH TO FREEZE button.
I. On the SU444 right side, make sure the blender
power plug is connected to the machine and
place the Blender Power Off/On switch in the ON
position.
WARNING
Hazardous Moving Parts
Blender shaft and agitator can grab and cause
injury. Do not operate blender without protective
shield or swing splash shield.
J. When the product is ready, the display will read
“SERVE”. Open the spigot to dispense product.
NOTE
If the product consistency needs to be adjusted, use
the Technician passcode and go to the Basic Set-
tings menu. Adjust the CutOut Consistency higher
to increase the consistency or lower to decrease
the consistency. Make adjustments in increments
of 5 for best results.
L. On the SU444 right side, push the spigot handle
to the right to activate the blender. The blender
will operate during or after dispensing product.
M. Do not operate the machine when the MIX LOW
message is displayed. Refi ll the mix containers
immediately.
NOTE
The machine has a standby and sleep mode. After
a preset number of freezing cycles, it will enter the
standby mode (followed by sleep mode) and remain
there until someone draws product or presses the
PUSH TO FREEZE button. In the sleep mode, the
machine will keep the product below 41°F (7.2°C).
Sleep modes do not take the place of cleaning
and sanitizing. Federal, State, and local regulatory
agencies determine frequency of cleaning and
sanitizing.
3.12 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. Mixes should provide a
satisfactory product in the 20°F to 24°F range. Diet and
low-carb mixes typically freeze to proper consistency at
higher temperatures.
When checking the temperature, stir the thermometer in
the frozen product to get an accurate reading.
Old mix, or mix that has been stored at too high a tempera-
ture, can result in a fi nished product that is unsatisfactory.
To retard bacteria growth in dairy based mixes, the best
storage temperature range is between 33° to 38°F (0.5°
to 3.3° C).
3.13 OPERATION OF MIX PUMP
The mix pumps are operated from the buttons on the
IntelliTec2™ touchpad. When the pump button is pressed
On, the mix pump motor will start pumping mix into the
freezing cylinder. When the set pressure is reached, the
mix pump will shut off automatically.
NOTE
The mix pump motor is equipped with an internal
overload that will “trip”, disabling the pump when
the motor is overloaded. Consult the troubleshoot-
ing section for corrective information. The internal
overload will automatically reset after cooling. If
the condition continues, contact a qualifi ed service
person.
