seconds before dispensing 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 freezer's capacity.
Do not operate the freezer when the MIX LOW light is
on or with less than 1-3/4" (4.4 cm) of mix in the
mix container. Refill the mix container 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 stand by 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 sanitizing. Frequency of cleaning and sani-
tizing is determined by Federal, State, and local
regulatory agencies.

3.11 MIX INFORMATION
Mix can vary considerably from one manufacturer to
another. Differences in the amount of butter-fat 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.
Proper product serving temperature varies from one
manufacturer's mix to another. Mixes should provide a
satisfactory product in the 17° to 20°F (-7° to -6°C) range.
Diet and low-carb mixes typically freeze to proper consis-
tency at higher temperatures.
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 from the appearance
and taste standpoint. 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).
C. Place the mix pump switch in the ON position. The
mix pump switch is located in the upper left hand
corner, inside the refrigerated cabinet (see Figure
21). Immediately open the spigot and let approxi
mately 8 ounces of liquid mix with sanitizing solu
tion drain out of the spigot.
D. Close the spigot and open the air bleed valve on the
front door by pushing the valve in and holding. Allow
the barrel to fill until the mix level is 1/2" (2.7 cm)
below air bleed valve, then release valve and pull
closed to lock in place.
E. Place the OFF-ON switch in the ON position, then
press and hold the PUSH TO FREEZE switch until
the freezer starts.
NOTE
After the Drive Motor starts, there will be a 3
second delay before the Compressor starts.
F. After about 6 to 10 minutes the freezer will shut off
and the green lens will illuminate. SERVE will be dis
played on the LCD screen. The product will be
ready to serve. Freeze down time may be shorter
for some frozen diet dessert mixes. High ambient
temperatures may extend freeze down time.
G. The refrigeration is automatically actuated when
the spigot is opened.For normal dispensing, move
the spigot handle fully open. This position provides
excellent control over the product and aids in
making desired shaped portions. Spigot Rate
Adjusters are located under the Header Panel, to
the immediate right of each Spigot Handle. Turning
the Spigot Rate Adjuster clockwise will increase
the dispense rate (see Figure 22).
The freezer is designed to dispense the product at a
reasonable draw rate. If the freezer is overdrawn, the
result will be a soft product and air pops. If this should
occur, allow the freezer to run for approximately 30
