GENERAL INFORMATION  
IMPORTANT: To the user of this manual - 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 FCB Solid-State Post-Mix  
Two-Flavor Dispenser with Hot-Gas Defrost (hereafter referred to as a Unit).  
UNIT DESCRIPTION  
The Unit (see Figure NO TAG) 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 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.

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 and also note beaters drive motors manufacturer’s name. No.  
6, No. 7, and No. 8 switches on DIP switch assembly on master circuit board must be set according to  
motors manufacturer and for 50 or 60 Hz operation.  
A CO2 cylinder delivers carbon dioxide (CO ) gas to an adjustable primary CO regulator assembly attached to  
2
2
the cylinder. 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 adjustable secondary CO regulators to  
2
2
carbonator tank and also two product-blender tanks inside the Unit. CO gas pressure pushes syrup out of soft  
2
drink tanks, through syrup sold-out float switches, through electrically-operated syrup solenoid valves, through  
adjustable syrup flow regulators, and on to product blender tanks. At the same time, plain water passes through  
water pressure regulator and is pumped into carbonator tank by water pump and is carbonated by CO gas  
2
pressure also entering tank. Carbonated water is pushed by CO gas pressure from carbonator tank, through  
2
electrically operated carbonated water solenoid valves through adjustable carbonated water flow regulators, and  
on to product blender tanks. Carbonated water and syrup enter tanks properly proportioned (blended) for  
desired BRIX of dispensed product by adjustment of syrup flow regulators. From product blender tanks, product  
is pushed by CO gas into freeze cylinders. The beater in each freeze cylinder is driven by an electric motor.  
2
Scraper blades, attached to beaters, scrapes product from cylinder walls as product enters freeze cylinders and  
is frozen. Transparent faceplate, attached to 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 freeze cylinder to atmosphere when filling cylinder with  
2
product. Electronic sensing on each freeze cylinder motor provides a means of adjusting viscosity (consistency)  
of 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 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.  
326142000  
2
MANUAL DEFROST SYSTEM  
The Manual hot-gas defrost system may be activated at any time by pressing ‘‘DEFROST’’ switch on front of  
Unit. Refrigeration compressor will operate for a short time, then both freeze cylinders will go into defrost and  
defrost for approximately 60-seconds. At end of manual defrost cycle, Unit will return to normal operation.  
Manual defrost may be cancelled at any time by pressing ‘‘CANCEL DEFROST’’ switch.  
AUTOMATIC DEFROST SYSTEM  
The automatic hot-gas defrost system may be programmed into Unit to occur up to nine different times a day  
with a minimum of two hours between defrost settings. At start of each automatic defrost cycle, refrigeration  
compressor will operate for 30-seconds to pump freon out of freeze cylinders evaporator coils. After freon has  
been pumped out of freeze cylinders evaporator coils, No. 1 freeze cylinders only will go into defrost cycle and  
defrost for approximately 7-minutes, then will return to normal operation. This ends 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 time programmed into the Unit. Automatic defrost may be  
cancelled at any time by pressing ‘‘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 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.

NOTE: Automatic defrost, sleep time, and wake up time may be used in any combination together or  
separately.  
FACEPLATE RELIEF VALVES  
The faceplate relief valves (see Figure 5), located in each faceplate, are spring-loaded valves that protect freeze  
cylinders from accidental over-pressure. The relief valve is also used to manually bleed CO gas from freeze  
2
cylinder to atmosphere during filling with product and if gas pockets form in cylinder during operation.  
PRODUCT SAMPLE VALVES  
The two product sample valves (see Figures 2 and 6), located behind front lower access panel, 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 product blender tanks to freeze cylinders (see  
Figures 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  
cylinder.  
PRIMARY CO2 REGULATOR  
The primary CO regulator (see Figure 2) controls CO pressure to soft drink tanks and Unit secondary CO  
2
2
2
regulators located behind lower front access panel. If necessary to adjust primary CO regulator, adjust as  
2
instructed.  
SECONDARY CO2 REGULATORS  
The three secondary CO regulators, located behind lower front access panel (see Figures 2 and 6), control  
2
CO pressure to carbonator and product blender tanks. If necessary to adjust secondary CO regulators, adjust  
2
2
as instructed.  
CARBONATED WATER FLOW REGULATORS  
The adjustable carbonated water flow regulators (see Figures 2 and 6), located in their respective systems,  
control carbonated water flow rate to the product blender tanks. The water flow regulators are factory adjusted  
at 1.5± 0.05 oz/sec and should not normally require adjustment. If adjustment is necessary, adjust as  
instructed.  
SYRUP FLOW REGULATORS  
The syrup flow regulators (see Figures 2 and 6), located in their respective systems, 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.  
DISPENSING VALVES  
Self-closing dispensing valves (see Figure 5 and 7), 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 CO gas  
2
breakout and secondary by freezing.  
326142000  
20  
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, 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 peak-use 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 drink. The degree of  
freezing is limited because finished drink is intended to be sipped through a straw. This is not possible if 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 drink dispensed. The dispensed product will have a normal variance due to the  
following conditions:  
21  
326142000  
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

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. Place No. 4 ‘‘BEATER MOTOR CURRENT READOUT’’ switch on DIP SWITCH assembly on master  
circuit board (see Figure 10) in ‘‘ON’’ position. Both freeze cylinders beater motors will start and operate  
and beaters motors current ratings will be displayed on message display.  
2. 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 10). These figures will fluctuate slightly with  
variations in line voltage and motor loads.  
3. After completion of adjusting beater motor current to A150B150 ± 2, make sure No. 5 ‘‘MOTOR CURRENT  
SELF-CALIBRATION’’ switch on DIP SWITCH assembly on master circuit board (see Figure 10) is in  
‘‘OFF’’ position. No. 5 switch in ‘‘OFF’’ position allows the ‘‘MOTOR CURRENT’’ SELF-CALIBRATION’’
