GENERAL DESCRIPTION
This section gives the description, theory of operation, and design data for the FCB (Frozen Carbonated
Beverage) Overcounter Post-Mix Dispenser with V3+ Features (hereafter referred to as a Unit).
UNIT DESCRIPTION
The Unit (see Figure 1) 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 which feeds both carbonatorblender 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 sides and back panels are easily removed and the front access door may be opened 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 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.

THEORY OF OPERATION
(see Figure 2)
A CO2 cylinder delivers carbon dioxide (CO2) gas to an adjustable primary CO2 regulator assembly which is attached
to the cylinder. The primary CO2 regulator assembly in turn delivers CO2 gas to adjustable secondary CO2 regulators
inside the Unit and also to two soft drink tanks. CO2 is delivered from the adjustable secondary CO2 regulators to the
carbonator tank and also to 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 tank 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
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 CO2 gas into the freeze cylinders. The beater in each freeze
cylinder is driven by an electric motor. Scraper blades, attached to the beaters, scrape product from the cylinder walls
as product enters the freeze cylinders and is frozen.
312028000
2
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.
FIGURE 1. FCB OVERCOUNTER POST-MIX

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 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 cylinders only will go into defrost cycle for approximately 7 minutes, then will return to normal operation. This ends the automatic defrost cycle of
the 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
312028000
‘‘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
for 60 seconds. After No. 1 freeze cylinder has defrosted, No. 2 freeze cylinder will go into defrost for 60 seconds. At
the 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 the Unit, refer to nameplate and note if Unit is to be
operated with 50 or 60 Hz power source.
60 HZ UNIT
IMPORTANT: Power circuit voltage across L1 and L2 terminals on contactor inside lower electrical
control box, with refrigeration compressor operating, must be in range of 198-253 VAC, 60 Hz
single-phase for proper operation.
A properly grounded 198-253 VAC, 60 Hz single-phase electrical circuit connected through a 30-amp minimumrated disconnect switch (not provided) fused at 30-amps (slow-blow) or circuit connected through an equivalent
HACR circuit breaker must be available to be connected to the electrical box located in lower back side of the
Unit. ALL WIRING MUST CONFORM TO NATIONAL AND LOCAL CODES. MAKE SURE UNIT IS PROPERLY
GROUNDED.
50 HZ UNIT
DANGER: To avoid possible fatal electrical shock or serious injury to the Operator, it is
required that an ELCB (earth leakage circuit breaker) be installed in the electrical power
circuit for all 50-Hz Units.
IMPORTANT: Power circuit voltage across L1 and L2 terminals on contactor inside lower control box,
with refrigeration compressor operating, must be in range of 209-253 VAC, 50 Hz single-phase for
proper operation.
A properly grounded 209-253 VAC, 50 Hz single-phase electrical circuit connected through a 30-amp minimumrated disconnect switch (not provided) fused at 30-amps (slow-blow) must be available to be connected to the
electrical box located in the lower back side of 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.
312028000

the 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 the UNIT
1. Open CO2 cylinder valve slightly to allow lines to slowly fill with gas, then open valve fully to backseat valve.
Back-seating valve prevents leakage around valve shaft.
ADJUSTING PRIMARY CO2 REGULATOR
IMPORTANT: If bag-in-box syrup supply system will be connected to the Unit instead of soft drink tanks,
primary CO2 regulator (see Figure 2) must be adjusted to no less than 80-psi.
1. Adjust primary CO2 regulator (see Figure 2) by turning regulator adjusting screw to the right (clockwise) until
regulator pressure reads 80 to 100-psig.“OUT OF CO2 ” warning light on control panel message display

PLACING UNIT IN OPERATING 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 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.
1. Disconnect electrical power from Unit at the electrical power source disconnect switch.
IMPORTANT: When installing Unit in it’s operating position, do not allow obstructions to block sides,
top, and front of the Unit which will block off cooling air intake to the inside of the Unit. Air flow through
the Unit must be present to provide adequate cooling for the refrigeration system. Refer to SELECTING
LOCATION for sides, top, and front clearances to be observed when placing Unit in operating position.
2. Referring to the preceding NOTE, very carefully, place the Unit in operating location.
3. Make sure the Unit is sitting level. The Unit may be leveled by using a carpenter’s level and adjusting the
four leveling legs installed on the Unit during installation.
4. Restore Unit to operation by connecting electrical power at the electrical power source disconnect switch.
ADJUSTING BEATER MOTOR CURRENT (EITHER SIDE)
Adjusting beater motor current (either side) procedure is very important and must be performed as instructed. Be
sure you fully understand the instructions before performing the current adjustments or doing any preventative
maintenance current readings check.
Any current adjustments or preventative maintenance current readings check on the beater motor
current (either side) must be performed with both freeze cylinders fully defrosted. A partially defrosted
freeze cylinder will cause false current readings to be displayed on the message display. Adjust beater
motor current (either side) as follows:
1. Using a flat blade screwdriver, turn lock counterclockwise to unlock the front access door (see Figure 5),
then open the door.
2. Remove four screws securing the upper electrical control box cover (control box located on back of the front
access door). Remove cover for access to the master circuit board (see Figure 4).
3. Place No. 4 ‘‘BEATER MOTOR CURRENT READOUT’’ switch on DIP SWITCH assembly on master circuit
board (see Figure 4) in ‘‘ON’’ position. Both freeze cylinders beater motors will operate and beaters motors
current ratings will be displayed on message display.
4. Display should be adjusted to read A150 B150 ± 2 by adjusting MOTOR CURRENT ADJUSTMENTS located on No. 1 and No. 2 relay circuit boards (see Figure 4). These figures will fluctuate slightly with variations in line voltage and motor loads.
5. After completion of adjusting beater motor current to A150 B150 ± 2, make sure No. 5 ‘‘MOTOR CURRENT
SELF-CALIBRATION’’ switch on DIP SWITCH assembly on master circuit board (see Figure 4) is in ‘‘OFF’’
position. No. 5 switch in ‘‘OFF’’ position allows the ‘‘MOTOR CURRENT’’ SELF-CALIBRATION’’ electronics
to automatically self-calibrate the beaters motors currents at completion of each defrost cycle.
15
312028000
CAUTION: IF NO. 4 ‘‘BEATER MOTOR CURRENT READOUT’’ SWITCH ON DIP SWITCH
assembly is placed in ‘‘ON’’ position and beater motor current readings were A155 B145
and switch was then placed back in ‘‘OFF’’ position without readjusting to A150 B150 ± 2,
the beater motor current has just been reset at A155 B145. Operating the FCB Dispenser at these
current readings may have serious effects on its operation.
ANY TIME THE NO. 4 ‘‘BEATER MOTOR CURRENT READOUT’’ SWITCH ON DIP SWITCH ASSEMBLY IS
PLACED IN ‘‘ON’’ POSITION, THE BEATER MOTOR CURRENT READINGS MUST BE RE-ADJUSTED TO
A150 B150 ± 2 AS INSTRUCTED. THEN, SWITCH MUST BE PLACED BACK IN THE ‘‘OFF’’ POSITION.
6. Close front access door, then use a flat blade screwdriver to turn lock clockwise to lock the door.
7. Install FRONT ACCESS PANEL (item 15) and SPACERS (item 14) and secure with THREAD CUTTING

FACEPLATE RELIEF VALVES
The faceplate relief valves (see Figure 5), located in each freeze cylinder faceplate, are spring-loaded valves
that protect freeze cylinders from accidental over-pressure. The relief valve is also used to manually bleed CO2
gas from freeze cylinder to atmosphere during filling with product and if gas pockets form in cylinder during operation.
PRODUCT SAMPLE VALVES
The two product sample valves are located behind the lower front access panel (see Figure 2 and Figure 6)
and are manually operated lever-type ball valves used to check product BRIX. Turn valve lever to line up with
attached line to open valve and at 90° angle with line to close valve.
PRODUCT SHUTOFF VALVES
The two product shutoff valves, located in lines leading from the product blender tanks to the freeze cylinders
(see Figure 2 and 6), are manually operated lever-type ball valves and are used to prevent product from
entering and filling freeze cylinders while adjusting BRIX of dispensed product. Shutoff valves may also be used
to shut off product to individual freeze cylinder for service and maintenance without disrupting operation of other
freeze cylinders.
PRIMARY CO2 REGULATOR
The primary CO2 regulator (see Figure 2) controls CO2 pressure to the soft drink tanks and the Unit secondary
CO2 regulators located behind the lower front access panel. If necessary to adjust the primary CO2 regulator,
adjust as instructed in the SERVICE AND MAINTENANCE section.
SECONDARY CO2 REGULATORS
The secondary CO2 regulators, located behind the lower front access panel (see Figure 2 and 6), control CO2
pressure to the carbonator and the product blender tanks. If necessary to adjust the secondary CO2 regulators,
adjust as instructed in the SERVICE AND MAINTENANCE section.
CARBONATED WATER FLOW REGULATORS
The adjustable carbonated water flow regulators, (see Figure 2 and 12) located behind the front access panel,
control carbonated water flow rate to the product blender tanks. The water flow regulators are factory adjusted
at 1.3 0.05 oz/sec and should not normally require adjustment. If adjustment is necessary, adjust as
instructed in the SERVICE AND MAINTENANCE section.
312028000
30
SYRUP FLOW REGULATORS
The syrup flow regulators located behind the front access door (see Figure 2 and Figure 12), are adjustable
regulators that control syrup flow rate to the product blender tanks for desired BRIX of dispensed product.
Adjust syrup flow regulators for desired BRIX as instructed in the SERVICE AND MAINTENANCE section.
DISPENSING VALVES
Self-closing dispensing valves (see Figure 5)), located on faceplates on front of Unit, are operated one at a
time or simultaneously to deliver product to the customer.
DISPENSED PRODUCT CONDITIONS
‘‘OVERRUN’’, AS APPLIED TO FROZEN CARBONATED BEVERAGES
Overrun Defined.
Overrun is product expansion that takes place in the frozen carbonated drink. It is caused primarily by CO2 gas
breakout and secondary by freezing.
Overrun is a Variable.
The percentage or degree of overrun depends on a number of factors. The specific syrup, BRIX, low dispensing
volume, carbonation level in liquid product, and freezing, all affect overrun. After these factors have been
considered, desired viscosity (product consistency) adjustment may be made on the Unit. The viscosity adjustment adjusts product texture from very wet to light.
Specific Product Ingredients Affect Overrun.
Each syrup has its own specific formulation of makeup. Baume, an important ingredient factor, may fall within
an extremely wide range. Fruit flavors contain citric acids that colas do not. Colas also differ in ingredients from
one brand to another. Each product formulation has its own peculiarities regarding the way the product will
absorb carbonation and the way it will release carbonation.
BRIX Affects Overrun.
Sugar in carbonated drinks is like anti-freeze in water. The higher the BRIX in a product, the greater resistance
the product has to freezing. Conversely, in products with lower BRIX, freezing takes place at higher
temperatures than for high-BRIX products. Thus, BRIX affects overrun because the amount of sugar in a drink
has a direct bearing on the product’s freezing characteristics.
DRAWING 1
DRAWING 2
DRAWING 3
Low Dispensing Volume Affects Overrun.
When Unit sits idle for a period of time and no drinks are dispensed, CO2 gas in the system takes a ‘‘set’’. When
first few drinks are drawn off after an idle period, CO2 gas has less tendency to break out as drink is dispensed.
The result is these casual drinks have less overrun than drinks dispensed during peakĆuse periods.
31
312028000
Carbonation Level in Liquid Product Affects Overrun.
The higher the specific carbonation level in a given product, the greater the potential for carbonation breakout in
frozen carbonated form of that drink. For example, drinks with 3.0 volume of carbonation will have more gas
breakout in frozen carbonated form, and more overrun, than will drinks that contain 2.0 volumes of CO2 gas.
Freezing Affects Overrun.
Freezing causes approximately a 10 percent expansion in dispensed frozen carbonated drinks. The degree of
freezing is limited because the finished drink is intended to be sipped through a straw. This is not possible if the
product is too ‘‘solid’’.
OPERATING CHARACTERISTICS
The product viscosity (product consistency) can be varied by adjustment and secondary CO2 regulator setting
from a high overrun light drink to a wet, heavy drink. The length of freezing cycle and amount of CO2 present in
product combine to create the drink dispensed. The dispensed product will have a normal variance due to the
following conditions:
1. If some time has elapsed since last drink was drawn from particular freeze cylinder and compressor has
not cycled on, the drink dispensed will have a tendency to be wetter, have slightly less overrun than normal
for the setting, and will not mound up as high. See Drawing 1.
NOTE: A cylinder freeze-up may be expected under casual draw conditions if an attempt is made to
eliminate drink described above by adjusting viscosity.
2. If product is drawn from freeze cylinder quite regularly, its viscosity (product consistency) will be maintained
at whatever viscosity adjustment was made within the normal variance of the compressor off and on cycle.
See Drawing 2.
3. If product is drawn continuously from freeze cylinder and rate is approaching capacity of the dispensing
unit, overrun of drink will increase just prior to point capacity is exceeded, and drink dispensed will turn
slightly wetter. See Drawing 3.
OPERATING UNIT
NOTE: The No. 1 freeze cylinder (see Figure 5) is the left-hand cylinder facing the front of the Unit. No.
2 freeze cylinder is to the right of No. 1 freeze cylinder.
1. Make sure ‘‘H2O OUT’’ fault message is not displayed on message display. This indicates no water supply
to Unit.
2. Make sure ‘‘CO2 OUT’’ fault message is not displayed on message display. This indicates no CO2 gas
supply to Unit.
3. Make sure ‘‘SYRUP 1’’ or ‘‘SYRUP 2’’ fault messages are not displayed on message display. This indicates
no syrup supply to Unit.
4. Make sure ‘‘AUTO BLEND 1’’, ‘‘AUTO BLEND 2’’, ‘‘AUTO 1’’, and ‘‘AUTO 2’’ control switches are pressed
for normal operation.
5. Place cup under dispensing valve, then dispense until cup is full of product.
6. Make sure viscosity (product consistency) is as desired. If not, adjust as instructed.
REPLENISHING SYRUP SUPPLY
IMPORTANT: The following CO2 and liquid disconnects disconnecting and connecting procedure for
soft drink tank replacement or filling soft drink tank in place must be performed in order as follows:
312028000
32
1. To disconnect soft drink tank from Unit
syrup system.
A. Disconnect liquid disconnect from soft drink tank. NOTE - Disconnecting liquid quick
disconnect from soft drink tank first prevents syrup from backflowing through Unit syrup flow
regulator, which may alter regulator adjustment.
B.
Second, disconnect CO2 quick disconnect from soft drink tank.
2. To connect soft drink tank into Unit syrup system.
A. First, connect CO2 quick disconnect to soft drink tank to pressurize tank.
B.
Second, connect liquid quick disconnect to soft drink tank.
Syrup supply should be checked daily and if necessary, replenished as instructed.
PRODUCT FLAVOR CHANGE
Perform syrup flavor change as instructed.
CHECKING CO2 SUPPLY
WARNING: CO2 displaces oxygen. Strict attention must be observed in the prevention of
CO2 (carbon dioxide) gas leaks in the entire CO2 and soft drink system. If a CO2 gas leak is
suspected, particularly in a small area, immediately ventilate the contaminated area before
attempting to repair the leak. Personnel exposed to high concentration of CO2 gas will experience
tremors which are followed rapidly by loss of consciousness and suffocation.
Make sure CO2 cylinder shutoff valve is fully opened and regulator assembly 1800-psi gage indicator is not in
shaded (‘‘change CO2 cylinder’’) portion of dial. If so, CO2 cylinder is almost empty and must be replaced as
instructed.
CLEANING AND SANITIZING
DAILY CLEANING
Daily or more often if necessary, wash all external surfaces of Unit, rinse with clean water, then wipe dry with
clean soft cloth. DO NOT USE ABRASIVE CLEANERS. Wash the drip tray and cup rest with warm water and
mild detergent, then rinse with clean water.
SANITIZING
The Unit syrup systems should be sanitized as instructed every 120-days and before and after storage periods
following parent company requirements and sanitizer manufacturers recommendations. Sanitize syrup systems
as instructed.
CLEANING CONDENSER COIL
The FCB Dispenser refrigeration system is equipped with a condenser coil (see Figure 6) that is cooled by two
condenser coil fans. Circulating air, required to cool the refrigeration system’s condenser coil, is drawn in
through a grilled panel on the right-hand side and is exhausted out through the opposite side and back grilled
panels. Restricting air circulation through the Unit will decrease its cooling efficiency. THE CONDENSER COIL
MUST BE CLEANED PERIODICALLY AS INSTRUCTED IN the SERVICE AND MAINTENANCE section.
LUBRICATION
Carbonator pump motor must be lubricated as instructed on the motor.
33
312028000
ADJUSTMENTS
