Note: The following paragraph describes the theory of operation for the Two-Flavor FCB Dispenser
(see Figure 2 ). The Four-Flavor FCB Dispenser theory of operation is the same as the Two- Flavor
Dispenser except the Four-Flavor (see Figure 3 ) has two carbonator tanks, four product-blender tanks,
and is connected to four soft drink tanks.
A CO
2
cylinder delivers carbon dioxide (CO
2
) gas to an adjustable primary CO
2
regulator assembly attached to
the cylinder. The primary CO
2
regulator assembly in turn delivers CO
2
gas to an adjustable secondary CO
2
regulators inside the Unit and also to the soft drink tanks. CO
2
is delivered from the adjustable secondary CO
2
regulators to the carbonator tank and also to the product-blender tanks inside the Unit. CO
2
gas pressure
pushes syrup out of the soft drink tanks through the syrup sold-out switches, through adjustable syrup flow
regulators, through electrically operated syrup solenoid valves, and on to the product blender tanks. At the
same time, plain water passes through the water pressure regulator and is pumped into the carbonator tank by
the water pump. It is carbonated by CO
2
gas pressure also entering the tank. Carbonated water is pushed by
CO
2
gas pressure from the carbonator tank, through adjustable carbonated water flow regulators, through
electrically operated carbonated water solenoid valves, and on to the product blender tanks. Carbonated water
and syrup enter the tanks properly proportioned (blended) for desired BRIX of dispensed product by adjustment
of the syrup flow regulators. From product blender tanks, product is pushed by the CO
2
gas into the freeze
cylinders. The beater in each freeze cylinder is driven by an electric motor. Scraper blades, attached to the
beaters, scrapes product from the cylinder walls as product enters the freeze cylinders and is frozen.
Transparent faceplate, attached to the front of each freeze cylinder, includes a self-closing dispensing valve and
a spring-loaded relief valve that protects freeze cylinder from accidental over pressure. The relief valve is also
used to bleed CO
2
gas pressure from the freeze cylinder to atmosphere when filling the cylinder with product.
Electronic sensing on each freeze cylinder motor provides a means of adjusting viscosity (consistency) of the
dispensed product to suit customer preference.
DEFROST SYSTEMS
The Unit is equipped with both manual and automatic hot-gas defrost systems. The automatic defrost system
may be programmed into the Unit to occur up to nine different times a day with a minimum of two hours
between defrost time settings or the system may be completely turned off.
MANUAL DEFROST SYSTEM
Two-Flavor FCB Dispenser
The Manual hot-gas defrost system may be activated at any time by pressing the ‘‘DEFROST’’ switch on front
of the Unit. Refrigeration compressor will operate for a short time, then both freeze cylinders will go into defrost
for approximately 60-seconds. At the end of the manual defrost cycle, the Unit will return to normal operation.
Manual defrost may be cancelled at any time by pressing the ‘‘CANCEL DEFROST’’ switch.
Four-Flavor FCB Dispenser
The Manual hot-gas defrost system may be activated at any time by pressing the “DEFROST” switch on front of
the Unit. Refrigeration compressor will operate for a short time, then both No. 1 and No.11 or No. 2 and No. 22
(depending upon which “DEFROST” switch was pressed) freeze cylinder only will go into defrost cycle for one
minute. At the end of the manual defrost cycle, Unit will return to normal operation. Manual defrost may be
cancelled at any time by pressing the “CANCEL DEFROST” switch.
AUTOMATIC DEFROST SYSTEM
Note: The following paragraph describes the Automatic Hot-Gas Defrost system operation for the
Two-Flavor FCB Dispenser No. 1 and No. 2 freeze cylinders. This paragraph also describes the
Automatic Hot-Gas Defrost system operation for the Four-Flavor FCB Dispenser No. 11 and No. 22
freeze cylinders which is identical to the No. 1 and No. 2 freeze cylinders.
