33. 

Place the Freezing Cylinder OFF/ON switch in 
the ON position.

34. 

Press the PUSH TO FREEZE button.

35. 

When the product is at 75% consistency, the 
display will read “SERVE”.

36. 

For normal dispensing, move the spigot handle 
fully open.

37. 

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.

38. 

Do not operate the machine when the MIX LOW 
message is displayed. Refi ll the mix container 
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.

The following section contains the recommended oper-
ating procedures for the safe operation of the machine.

(0.23 liters) of sanitizing solution and liquid mix. 
Close the spigot.

G.

pressing and holding. Hold the valve open until 
the mix level in the freezing cylinder is 1/2” from 
the air bleed valve.
