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 elec-  
tric motor, one refrigeration system with a 2-horsepower compressor, one carbonator which 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 sides and back pan-  
els are easily removed and the front access door may be opened to facilitate installation and service and mainte-  
nance. 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 CO cylinder delivers carbon dioxide (CO ) gas to an adjustable primary CO regulator assembly which is attached  
2
2
2
to the cylinder. The primary CO regulator assembly in turn delivers CO gas to adjustable secondary CO regulators  
2
2
2
inside the Unit and also to two soft drink tanks. CO is delivered from the adjustable secondary CO regulators to the  
2
2
carbonator tank and also to product-blender tanks inside the Unit. CO gas pressure pushes syrup out of the soft  
2
drink tanks through the syrup sold-out switches, through adjustable syrup flow regulators, through electrically oper-  
ated 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 CO  
2
gas pressure also entering the tank. Carbonated water is pushed by CO gas pressure from the carbonated water  
2
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 gas into the freeze cylinders. The beater in each freeze  
2
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.

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 gas pressure from the freeze cylinder to atmosphere when filling the cylinder with product. Electronic sens-  
2
ing 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 approxi-  
mately 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 compres-  
sor 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 de-  
frost 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 can-  
celled at any time by pressing the ‘‘CANCEL DEFROST’’ switch.

‘‘SLEEP’’ (SLEEP TIME)  
‘‘SLEEP’’ (SLEEP TIME) may be programmed into Unit to allow Unit to go into sleep time (Unit shut down, freeze cyl-  
inders 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 de-  
sired time. When programmed wake up time is reached, an alarm will sound for a short duration, then Unit will re-  
sume normal operation.  
NOTE: Automatic defrost, sleep time, and wake up time may be used in any combination together or sepa-  
rately.

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 L and L terminals on contactor inside lower electrical  
1
2
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 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 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 L and L terminals on contactor inside lower control box,

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 its 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 carpenters 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 lo-  
cated on No. 1 and No. 2 relay circuit boards (see Figure 4). These figures will fluctuate slightly with varia-  
tions 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.

‘‘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 CO gas  
2
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 adjust-  
ment 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, CO gas in the system takes a ‘‘set’’. When  
2
first few drinks are drawn off after an idle period, CO gas has less tendency to break out as drink is dispensed.  
2
The result is these casual drinks have less overrun than drinks dispensed during peakĆuse periods.

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 CO gas.  
2
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 CO regulator setting  
2
from a high overrun light drink to a wet, heavy drink. The length of freezing cycle and amount of CO present in  
2
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.

ADJUSTING CARBONATOR TANK LIQUID LEVEL  
The carbonator tank liquid level (pump cut-in and cut-out) was adjusted at the factory and should require no fur-  
ther adjustment. However, if incorrect setting is suspected, check and make necessary adjustments as follows:  
1. Remove Unit back and side panels as instructed for access to carbonator and carbonated water volume  
sample valve (see Figure 6 and 14).  
2. To check carbonator tank total fill; allow carbonator water pump motor to operate and fill tank with carbon-  
ated water. After pump cycles off, disconnect electrical power from Unit.  
3. Using container graduated in ounces, open carbonator carbonated water sample valve and completely  
drain carbonator tank into container. Total carbonated water volume dispensed should be 40 to 58-ounces  
maximum.  
4. If total carbonated water dispensed is below 40 ounces, loosen screw securing level control switches ac-  
tuator bracket (see Figure 14 ) and move actuator bracket up slightly. If more than 58 ounces, maximum of  
carbonated water was dispensed, move actuator bracket down, then tighten screw. MAKE ADJUST-  
MENTS IN SMALL INCREMENTS.  
5. Connect electrical power to Unit and allow carbonator tank to fill with water until water pump cycles off.  
6. Repeat steps 2 through 5 preceding as many times as necessary until correct carbonated water volume  
adjustment is achieved.
