recommended if the ambient temperature is at 75° F. The times will vary depending on the ambient temperature (a

higher ambient temperature requires more time for the product to cool).

Viscosity Setting

The control system includes a function to select the desired product viscosity. This function is referred to as “Vis-

cosity Setting”. There are selectable viscosity ranges from 1-9. The higher the number selected, the more viscous

the frozen product in the barrel becomes. This increased viscosity is achieved by freezing the product in the barrel

to a lower temperature thereby increasing ice crystal size/growth. As the ice crystal size increases, however, there

is potential for product quality to diminish.

Cornelius recommends that the viscosity settings be set at the lowest possible setting to achieve the desired drink qual-

ity. In most typical installations using a sugar-based syrup, acceptable drink quality can be achieved by programmed vis-

cosity settings in the range of 3-5 for Viper.

Diet FCB syrups freeze much more readily than sugar based syrups, so the viscosity setting should be selected at the

minimum value available (which is 1 or 2 for the Viper).

CO2 Setting

The control system includes a function to adjust the desired product overrun. This function is referred to as the

“CO

2 Setting”. This setting is adjustable from 0 to 100% in 5% increments.

Typically, 40 to 45% settings on the pulse valves creates 100% overrun.

STARTING THE UNIT
