FCB Pinnacle 2 and 4 Flavor Operator's Manual
2. Programmed Defrost Scheduling
The control system in Cornelius FCB equipment includes a function to automatically defrost product in
the barrel at programmed times. Programmed defrosts must be scheduled frequently to ensure that
product quality within the barrel is maintained. Failure to defrost regularly during periods of low
throughput will allow increased ice crystal growth, with a possible decrease in product quality. Regular
throughput of dispensed product will replenish the barrel frequently with liquid and reduce the
requirements of programmed defrosts.
Cornelius recommends that programmed defrosts be scheduled to occur during any 3 hour
window during which time dispensed product throughput is low. Low throughput is defined as
less than 8 x 16oz drinks per barrel during any 3-hour window.
3. Viscosity Setting
The control system in Cornelius FCB equipment includes a function to select the desired product
viscosity. This function is referred to as "Viscosity Setting". With V-series there is a selectable Viscosity
Setting range from 4–12, and with Pinnacle, the range is 1–9. The higher the number selected the more
viscous the frozen product in the barrel will become. 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 quality. In most typical installations using a sugar-based syrup, acceptable
drink quality can be achieved by programmed Viscosity Settings in the 8-9 range for V-series and
in the range of 4-5 for Pinnacle.
Diet FCB syrups freeze much more readily than sugar based syrups, so the Viscosity Setting
should be selected at the minimum value available, 4 for V-series and 1 for Pinnacle equipment.

Control Panel Overview
The Pinnacle is controlled by a microprocessor that monitors and controls the major systems and compo-
nents of the machine. The microprocessor is pre-programmed at the factory to perform the tasks neces-
sary to keep the Pinnacle operating correctly. The microprocessor keeps track of diagnostic information
that is used when adjusting and/or repairing the machine.
Error messages are displayed on the Control Panel located behind the lighted merchandising panel (see
Figure 2). There are two levels of Control Panel access: one used by the operator for normal operations,
and one used by qualified service technicians for installation and service functions.
The Control Panel has many different displays of information called Menus. The first menu (menu 1) that
is displayed is the BARREL STATUS menu. From each menu there is a button to return to the previous
menu and another button to advance to the next menu (if applicable).
