is off. If it is not, press the On/Off Left or On/Off

NOTE
If the freezing cylinder is not off, the control will
not go into Clean mode. This is to protect from ac-

dipped in sanitizing solution, clean the hopper
sides, mix inlet regulator and underside of the
hopper cover.
H. After fi ve minutes, open the spigot to expel
sanitizing solution. Drain all of the solution from
the machine.

button to stop the auger. Allow the freezing cylinder
to drain completely.
The machine is now sanitized and ready for adding mix.
3.9 FREEZE DOWN AND OPERATION
A. Sanitize immediately before use.
B. Make sure the display shows the freezing cylinder
is off. If it is not, press the On/Off Left or On/Off
Right button to turn it off.
C. Fill the hopper with at least 2.5 gallons of mix.
D. Place a container under the spigot and open the
spigot to allow the mix to fl ush out about 8 ounces
(0.23 liters) of sanitizing solution and liquid mix.
E. Press the On/Off button for the cylinder.
F. Press the PUSH TO FREEZE button.
NOTE
After the drive motor starts, there is a 3-second
delay before the compressor starts.
G. When the product is at 75% consistency, the
display will read “SERVE”. Open the spigot to
dispense product.
H. The machine dispenses product at a reasonable
draw rate. If the machine is overdrawn, the result
is a soft product or a product that will not dispense
at all. If this occurs, allow the machine to run for
approximately 30 seconds before dispensing more
product. A dispense rate adjustor is located under
the header panel, to the immediate right of the
spigot handle. Turning the knob counterclockwise
will decrease the dispense rate.
I. Do not operate the machine when the MIX LOW
message is displayed. Refi ll the mix container
immediately.
NOTE
The control has a standby mode for Serve 1 and
a sleep mode for Serve 1 and Serve 2. After a
preset number of freezing cycles in Serve 1, 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 Serve 2
the control directly goes into the Sleep 2 mode. In
the sleep mode, the machine will keep the product
below 41°F (5°C). Sleep modes do not take the
place of cleaning and sanitizing. Federal, State,
and local regulatory agencies determine frequency
of cleaning and sanitizing.
3.10 FINE CONSISTENCY ADJUSTMENT

C. On the Fine Consistency Adjustment screen, press
the SEL button and use the arrows to modify the
setting. Adjust the Fine Consistency higher to
increase the consistency or lower to decrease
the consistency.
D. Press the SET button to save the changes. Make
adjustments in increments of 5 for best results.
