UALITY
It has been determined that the following factors can affect the rate at which product quality diminishes (as indi-
cated by a change in product appearance).

Dispensed Product Throughput

Programmed Defrost Scheduling

Viscosity Setting
Cornelius recommends the following instructions be read and followed relative to operating and establishing set-
tings for the FCB equipment. Cornelius equipment service manuals contain instructions on how to program set-
tings within the control system. Operators who have not been trained on servicing Cornelius FCB equipment
should not attempt to modify equipment settings but should contact an accredited service provider.
Cornelius makes the following recommendations to help assure maximum product quality.
Dispensed Product Throughput
FCB equipment is designed to provide a high throughput of frozen carbonated product to meet peak draw
demands. Where low product throughput is experienced, there is the potential for product quality to diminish. The
information shown in Table 31. outlines the minimum throughput per barrel that must be dispensed on a 24 hour
basis.
NOTE: Cornelius recommends that, in conditions where the FCB machine is operational and the min-
imum throughput (as described in Table 31. is not met on a per barrel basis, product should
be dispensed and discarded to increase throughput and help assure that product quality is
maintained.
NOTE: Data in Table 31. assumes equipment has been correctly installed, commissioned and cali-
brated as per directions contained in all technical literature published by Cornelius and the
recommendations contained in this document have been followed.
Cornelius recommends that, in conditions where the FCB machine is operational and the minimum throughput is
not met on a per barrel basis, product should be dispensed and discarded to increase throughput and help
assure that product quality is maintained.
Programmed Defrost Scheduling
The control system in the Viper system includes a function to automatically defrost product in the barrel at pro-
grammed intervals based on the viscosity of the product. Programmed defrosts are scheduled frequently to
ensure that product quality within the barrel is maintained. Failure to defrost regularly during periods of low
throughput allow increased ice crystal size, with a possible decrease in product quality. Regular throughput of dis-
pensed product replenishes the barrel frequently with liquid and reduces the requirements for programmed
defrosts. The unit automatically senses the lack of throughput and maintains the product quality by defrosting the
barrels more frequently when throughput is slow.
Sleep Mode Recommendations
Cornelius recommends programming a sleep period for the machine during any amount of time over 3 hours that
the unit is not used. This increases the life of the machine and reduces energy consumption.
