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.
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 CO
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.
2
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.

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.
3312028000
‘‘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.

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.
15312028000
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.
