1. A wakeup time must be programmed after the sleep period to return the unit to nor mal operation Cornelius recommends programming the wakeup time for approxi mately 20 minutes before the product is needed This is the time 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 The control system includes a function to select the desired product viscosity This function is referred to as Viscosity 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 set ting to achieve the desired drink quality In most typical installations using a sugar based syrup acceptable drink quality can be achieved by programmed viscosity set tings in the range of 3 5 for Viper Diet FCB syrups freeze much more readily than sugar based syrups so the viscosity set ting should be selected at the minimum value available which is 1 or 2 for the Viper The control system includes a function to adjust the desired product overrun This
