there until someone draws product or presses the
PUSH TO FREEZE button. In the sleep mode, the
machine will keep the product below 45°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 pump switch is located at the front of the machine.
When a pump switch is placed in the ON position, 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. When the switch is placed in
the OFF position, the mix pump will not operate.
NOTE
The mix pump motor is equipped with an internal
overload that will “trip”, disabling the pump when
the motor is overloaded. Consult the trouble shoot-
ing section for corrective information. The internal
overload will automatically reset after cooling. If
the condition continues, contact a qualifi ed service
person.
