GENERAL DESCRIPTION

This section gives the description, theory of operation, and design data for the FCB 3 H.P. Two-Flavor Post-Mix
Dispenser with Hot-Gas Defrost and V3+ Features (hereafter referred to as a Unit).

UNIT DESCRIPTION

The Two-Flavor FCB Dispenser (see Figure 1) consists basically of two freeze cylinders each containing an internal
beater driven by an electric motor, one refrigeration system with a 3-horsepower compressor, two carbonated water
tanks which feed 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.

FIGURE 1. FCB DISPENSER

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 FCB Dispenser (depending upon the model number) refrigeration system is either

“air-cooled” or “water-cooled”.

“AIR-COOLED”

The “air-cooled” FCB Dispenser refrigeration system is equipped with a condenser coil that is cooled by a
condenser coil fan.

“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 Figure 2)

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.

Note: The following paragraph describes the theory of operation for the Two-Flavor FCB Dispenser (see
Figure 2).

A CO2 cylinder delivers carbon dioxide (CO2) gas to an adjustable primary CO2 regulator assembly attached to the
cylinder. The primary CO2 regulator assembly in turn delivers CO2 gas to an adjustable secondary CO2 regulators
inside the Unit and also to the soft drink tanks. CO2 is delivered from the adjustable secondary CO2 regulators to
the two carbonated water tanks and also to the product-blender tanks inside the Unit. CO2 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 carbonated water tanks by the water
pump and is carbonated by CO2 gas pressure also entering the tank. Carbonated water is pushed by CO2 gas
pressure from the carbonated water tanks, 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 CO2 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 CO2 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

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 and
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.

AUTOMATIC DEFROST SYSTEM

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 and
defrost 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.

3 312026000

‘‘SLEEP’’ (SLEEP TIME)

‘‘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 and defrost for 60-seconds. After No. 1 freeze cylinder has defrosted, No. 2 freeze cylinder will go into
defrost and defrost 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.

A properly grounded 198-253 VAC, 60Hz 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.

SELECTING LOCATION

CAUTION: This Unit is intended for indoor installation only. Do not install this Unit in an
outdoor environment which would expose it to the outside elements.

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 the grille on front and exhausted out through the 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.

CAUTION: Do not place or store anything on top of the Unit.

INSTALLING UNIT

PLACING UNIT IN OPERATING LOCATION

1. Place Unit in operating location meeting requirements of SELECTING LOCATION.

The FCB Dispensers manufactured prior to the model 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 redesign 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.

IMPORTANT NOTICE

3120260007

Note: An alternate to sealing the Unit base to the floor would be to install the available 4-inch Caster Kit
(P/N 309570000).

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.

PREPARATION FOR OPERATION

TURNING ON ELECTRICAL POWER TO UNIT

Turn on electrical power to Unit. Operational status of Unit is now being displayed as fault messages on control
panel message display. The following fault messages will be continuously displayed at 2-second intervals until
necessary operation requirements are satisfied.

‘‘OFF 1’’ (Beater Motor No. 1 not operating)
‘‘OFF 2’’ (Beater Motor No. 2 not operating)
‘‘H2O OUT’’ (No water supply to Unit)
‘‘CO2 OUT’’ (No CO2 gas supply to Unit)
‘‘SYRUP 1’’ (No syrup supply to Unit No. 1 syrup

system)
‘‘SYRUP 2’’ (No syrup supply to Unit No. 2 syrup
system)

TURNING ON CO2 SUPPLY TO UNIT

1. Open CO2 cylinder valve slightly to allow lines to slowly fill with gas, then open valve fully to back seat
valve. Back-seating valve prevents leakage around valve shaft.

IMPORTANT: If bag-in-box syrup supply system will be connected to the Unit instead of soft drink
tanks, the primary CO2 regulator (see figure 2) must be adjusted to no less than 80-PSI.

2. For soft drink tanks installation (see Figure 2), adjust primary CO2 regulator by turning regulator adjusting
screw to the right (clockwise) until regulator pressure reads 80 to 100-psig. OUT OF CO2 warning light on
