GENERAL INFORMATION
IMPORTANT: This manual is a guide for installing, operating, and maintaining this equipment. Refer to
Table of Contents for page location of information pertaining to questions that arise during installation,
operation, service and maintenance, or troubleshooting this equipment.
GENERAL DESCRIPTION
This section gives the description, theory of operation, and design data for the Two or Four-Flavor FCB
Post-Mix Dispenser with Hot-Gas Defrost and V3+ Features (hereafter referred to as a Unit).
UNIT DESCRIPTION
TWO-FLAVOR FCB DISPENSER
The Two-Flavor FCB Dispenser (see Figure 2) consists basically of two freeze cylinders, each containing an
internal beater driven by an electric motor, one refrigeration system with a 2-horsepower compressor, one
carbonator that feeds both carbonator-blender tanks, a timer-controlled automatic hot-gas defrost system to
defrost the freeze cylinders, and interconnecting tubing, components, and fittings necessary to regulate,
transfer, and dispense product.
The components are attached to a steel frame and are enclosed in a steel cabinet. The cabinet panels are
easily removed to facilitate installation and service and maintenance. A transparent faceplate, with an integral
relief valve and a removable self-closing dispensing valve, is mounted on front of each freeze cylinder. A
removable drip tray, with cup rest, is located directly below the dispensing valves.
FOUR-FLAVOR FCB DISPENSER
The Four-Flavor FCB Dispenser (see Figure 3 ) consists basically of four freeze cylinders, each containing an
internal beater driven by an electric motor, two refrigeration systems (one for each two freeze cylinders), two
carbonators (one carbonator feeding two carbonator-blender tanks), a timer-controlled automatic hot-gas defrost
system to defrost the freeze cylinders, and interconnecting tubing, components, and fittings necessary to
regulate, transfer, and dispense product.
The components are attached to a steel frame and are enclosed in a steel cabinet. The cabinet panels are
easily removed to facilitate installation and service and maintenance. A transparent faceplate, with an integral
relief valve and a removable self-closing dispensing valve, is mounted on front of each freeze cylinder. A
removable drip tray, with cup rest, is located directly below the dispensing valves.
CAUTION: Before shipping, storing, or relocating Unit, syrup systems must be sanitized
and all sanitizing solution must be purged from syrup systems. All water must also be
purged from plain and carbonated water systems. A freezing ambient environment will
cause residual sanitizing solution or water remaining inside Unit to freeze resulting in damage to
internal components.

REFRIGERATION SYSTEMS
Note: The Two or the Four-Flavor FCB Dispenser (depending upon the model number) refrigeration
system is either “air-cooled”or “water-cooled”.
“Air-Cooled”
The “air-cooled”Two-Flavor FCB Dispenser refrigeration system is equipped with a condenser coil that is cooled
by a condenser coil fan (The Four-Flavor FCB Dispenser is equipped with two condenser coils and two
condenser coil fans).
“Water-Cooled”
The “water-cooled”Two-Flavor FCB Dispenser refrigeration system is equipped with a Refrigeration Cooling
Coil Assembly that contains both refrigerant and plain water cooling coils. Circulating cool plain water through
the cooling coil cools the refrigerant also inside the coil. During installation, City cold plain water is connected to
the FCB Dispenser Refrigeration Cooling Coil water inlet line labeled “COOLING WATER IN”. The water drain
line labeled “COOLING WATER OUT”must be routed to and be connected to a permanent drain.
THEORY OF OPERATION
(see applicable Figure 2 or 3)
IMPORTANT: Before connecting electrical power to Unit, refer to nameplate and note if Unit is to be
operated with 50 or 60 Hz power source.

42813
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.
ACO2cylinder delivers carbon dioxide (CO2) gas to an adjustable primary CO2regulator assembly attached to
the cylinder. The primary CO2regulator assembly in turn delivers CO2gas to an adjustable secondary CO2
regulators inside the Unit and also to the soft drink tanks. CO2is delivered from the adjustable secondary CO2
regulators to the carbonator tank and also to the product-blender tanks inside the Unit. CO2gas 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 CO2gas pressure also entering the tank. Carbonated water is pushed by
CO2gas 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 CO2gas 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 CO2gas 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.

52813
The automatic hot-gas 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 settings. At the start of each automatic defrost cycle,
refrigeration compressor will operate for 30-seconds to pump freon out of the freeze cylinders evaporator coils.
After freon has been pumped out of the freeze cylinders evaporator coils, No. 1 freeze cylinder only will go into
defrost cycle for approximately 7 minutes, then will return to normal operation. This ends the automatic defrost
cycle of No. 1 freeze cylinder. No. 2 freeze cylinder will defrost 30-minutes after the start of No.1 freeze cylinder.
The next automatic defrost cycle will occur according to the time programmed into the Unit. Automatic defrost
may be cancelled at any time by pressing the ‘‘CANCEL DEFROST’’ switch.
‘‘SLEEP’’ (SLEEP TIME)
Note: The following paragraph describes “SLEEP”(SLEEP TIME) operation for the Two-Flavor and the
Four-Flavor FCB Dispensers No. 1 and No. 2 freeze cylinders. The “SLEEP”(SLEEP TIME) operation for
the Four-Flavor FCB Dispenser No. 11 and No. 22 freeze cylinders is identical to the No. 1 and No. 2
freeze cylinders.
‘‘SLEEP’’ (SLEEP TIME) may be programmed into Unit to allow Unit to go into sleep time (Unit shut down,
freeze cylinders beaters and refrigeration systems not operating). At start of sleep time, refrigeration
compressor will operate for 30-seconds to pump freon out of freeze cylinders evaporator coils, then No.1 freeze
cylinder will go into defrost cycle for 60-seconds. After No.1 freeze cylinder has defrosted, No. 2 freeze cylinder
will go into defrost cycle for 60-seconds. At end of No. 2 freeze cylinder defrost, Unit will shut down and go into
sleep time.
‘‘WAKE UP’’ (WAKE UP TIME)
‘‘WAKE UP’’ (WAKE UP TIME) may be programmed into the Unit to allow Unit to resume normal operation at a
desired time. When programmed wake up time is reached, an alarm will sound for a short duration, then Unit
will resume normal operation.
NOTE: Automatic defrost, sleep time, and wake up time may be used in any combination together or
separately.

ELECTRICAL POWER REQUIREMENTS
IMPORTANT: Before connecting electrical power to Unit, refer to nameplate and Note if Unit is to be
operated with 50 or 60 Hz power source.
TWO-FLAVOR FCB DISPENSER
A properly grounded 198-253 VAC, 60 Hz or 209-253 VAC, 50 Hz single-phase electrical circuit with a 30-amp
minimum-rated disconnect switch (not provided) fused at 30-amps (slow-blow) or circuit connected through an
equivalent HACR circuit breaker must be available to the Unit. ALL WIRING MUST CONFORM TO NATIONAL
AND LOCAL CODES. MAKE SURE UNIT IS PROPERLY GROUNDED.
FOUR-FLAVOR FCB DISPENSER
A properly grounded 198-253 VAC, 50Hz or 209-253 VAC, 50 Hz single-phase electrical circuit with a 50-amp
minimum-rated disconnect switch (not provided) fused at 50-amps (slow-blow) must be available to the Unit.
SELECTING LOCATION
IMPORTANT: Unit operating ambient temperature MUST NOT EXCEED 100°F. Operating ambient in
excess of 100°F will automatically void the factory warranty and will eventually result in Unit failure.
Several means are available to achieve proper ambient temperature and air circulation around the Unit
which are wall air intake grilles and ceiling exhaust fans, air conditioning, etc. Consult local codes.
Locate Unit so the following requirements are satisfied.

1. Close to a plain water inlet supply line with a minimum pressure of 12 psig.
NOTE: “AIR-COOLED FCB DISPENSER
The “air-cooled”FCB Dispenser refrigeration system is equipped with a condenser coil that is cooled
by a condenser coil fan. Circulating air, required to cool the refrigeration system’s condenser coil, is
drawn in through grille on front and exhausted out through sides and back of Unit. Restricting air
circulation through the Unit will decrease its cooling efficiency.
2. When installing Unit, do not allow obstruction to block grille on front which will block off air intake to inside
of Unit. If installation dictates only one side or back being unobstructed, allow 18-inches clearance between
Unit and obstruction. If both sides or one side and back are unobstructed, allow 12-inches clearance. If
both sides and back are unobstructed, allow 6-inches clearance.
INSTALLING UNIT
PLACING UNIT IN OPERATING LOCATION
1. Place Unit in operating location meeting requirements of SELECTING LOCATION.
IMPORTANT NOTICE
The FCB Dispensers manufactured prior to the models documented in this manual were elevated in the front
(dispensing valve side) 1/4 to 3/8-inch higher than the back when placing the Unit in operating position to
eliminate gas pockets being trapped inside the freeze cylinders. Due to a re-design of the foam pack in the
models documented in this manual, elevating the front of the Dispenser is no longer required. The Dispenser
must be leveled at time of placing in operating location.
Note: An alternate to sealing the Unit base to the floor would be to install the 4-inch Caster Kit
provided with the Unit. Refer to installation Instructions provided with the kit for installation
instructions. .
2. After Unit has been placed in operating location, make sure it is sitting in a level position.
3. To comply with National Sanitation Foundation (NSF) requirements, Unit installed with base contacting floor
must have base sealed to floor with Dow Corning RTV 731 or equivalent.
INSTALLING DRIP TRAY SUPPORTS, DRIP TRAY, AND CUP REST
1. Install DRIP TRAY SUPPORTS (item 7) on panel above lower front access panel on front of Unit. Secure
supports to panel with THREAD CUTTING SCREWS (item 6).
2. Place DRIP TRAY (item 9) in FRAME, DRIP TRAY (item 8), then slide frame up on drip tray supports on
front of Unit.
INSTALLING DRIP TRAY DRAIN HOSE KIT
