SAFETY PRECAUTIONS
We at FBD are concerned about your safety. Please carefully read the following precautions before working with the
FBD553D unit. This will familiarize you with proper equipment handling techniques.
LIFTING
• To avoid personal injury or damage, do not attempt to lift the unit without help. The empty unit weighs
approximately 365 pounds (165 kg). The use of a mechanical lift is recommended.
• Use gloves to protect hands from being injured by the edges of cross bracing if lifting by hand.
• Use proper equipment and lifting techniques when lifting or moving equipment. The unit is top heavy.
Maintain unit in a vertical, upright position when lifting and positioning the unit.
ELECTRICAL
•This unit must be properly electrically grounded to avoid possible fatal electrical shock or serious
injury to the operator. The power cord is provided with a three prong grounded plug. If a three-hole
grounded electrical outlet is not available, use an approved method to ground the unit. Only qualified
electricians should perform this task and the work performed should meet all applicable codes.
• Always disconnect electrical power to the unit to prevent personal injury before attempting any
internal maintenance. Only qualified personnel should service internal components of electrical
wiring.
CARBON DIOXIDE (CO2)
•CO2(carbon dioxide) displaces oxygen. Strict attention must be observed in the prevention of CO2
gas leaks in the entire CO2and soft drink system. If a CO2gas leak is suspected, immediately
ventilate the contaminated area before attempting to repair the leak. Personnel exposed to high
concentrations of CO2gas will experience tremors which are followed rapidly by loss of conscious-
ness and suffocation.
• To avoid personal injury and/or property damage, always secure CO2cylinders in an upright position
with a safety chain to prevent cylinders from falling over. Should the valve become accidentally
damaged or broken off, a CO2cylinder can cause serious personal injury.

the pressure should be set at 115 to 120 PSIG (793.5 to 828.0 KPa) and a secondary
regulator installed at the unit to reduce the pressure to 70-72 PSIG (482.6 to 496.4 KPa).
B. Syrup supply - Bag-in-Box or five (5) gallon syrup tank (figal).
C. Water supply with a minimum flowing pressure of 30 PSIG (206.8 KPa) and a maximum static
pressure of 70 PSIG (483.0 KPa).
2. RECEIVING AND UNPACKING UNIT
2.1 RECEIVING
Each unit is tested and thoroughly inspected before shipment. At the time of shipment, the carrier
accepts the unit and any claim for damages must be made with the carrier. Upon receiving the unit
from the delivering carrier, carefully inspect carton for visible indication of damage. If damage exists,
have carrier note same on bill of lading and file a claim with the carrier.
2.2 UNPACKING
A. Cut banding from shipping carton and remove carton by lifting up. Remove protective side
panels and four corner protectors.
B. Remove drip tray assembly, accessory kit and manual from top packaging. Contact the dealer
if any parts are missing or damaged.
C. Remove side panels from unit.
D. Inspect unit for concealed damage. If evident, immediately notify delivering carrier and file a
claim against same.
E. Lift unit up by the frame cross bracing and remove lower portion of carton.
F. Remove shipping board from bottom of unit by accessing and removing the bolts located on the
underside of the shipping board.
3. INSTALLING THE UNIT
There are several ways to install the unit. Follow the appropriate directions for the method you are
using. Insure that there is a minimum of twelve (12) inches (30.48 cm) ABOVE and two (2)
inches (5.08 cm) on the SIDES and BEHIND the unit for proper ventilation (see Figure 1.1).
3.1 FLUSH MOUNTING
Flush mounting is when the unit is mounted on a countertop. Follow the following guidelines to
ensure a proper installation.
A. Be sure the counter will support 390 pounds (177 kg) the full length of the unit (including the drip
tray). If permanently mounting the unit to a countertop, use the information in Section 14.1 to

2

Figure 4.1
mark and drill the four (4) mounting holes in the countertop.
B. With the side panels removed, lift unit by the frame cross bracing and place unit on the counter.
C. If permanently mounting the unit to a countertop, install four (4) 3/8-16 UNC bolts (not included)
through the underside of the counter [through the four (4) mounting holes drilled in the step just
above], and into the frame.
D. When the dispenser is to be permanently mounted to the counter top, seal dispenser base to
counter top with a bead of clear silicone caulk or sealant which provides a smooth and easily
cleaned bond to the counter.
3.2 ROLL AROUND CART
Aroll around cart is used when a suitable countertop is not available and allows the unit to be moved
for cleaning. These can be purchased from the dealer.
A. Lock the wheels on the roll around cart.
B. With the side panels removed, lift unit by the frame cross bracing and place the unit on the cart.
C. Secure the unit to the cart by installing four (4) 3/8-16 UNC bolts (not included) through the cart
mounting holes and into the frame of the unit.
D. When the dispenser is to be permanently mounted to the roll around cart, seal dispenser base
to cart with a bead of clear silicone caulk or sealant which provides a smooth and easily cleaned
bond to the counter.
4. CONNECTING TO ELECTRICAL POWER
Continuity
Ground
Use the following guidelines to connect electrical power to the machine for both 50 and 60 Hz service.
A. The machine requires single phase 230VAC. If line voltage is below 215VAC or above 245VAC,
a10% buck and boost transformer must be used. If a buck and boost transformer is installed,
ensure that the boosted leg is on L1 of the contactor. Operation below 215VAC or above
245VAC may damage the unit and cause inconsistent performance. This also voids all
warranties.
B. If connected to a "delta" three phase electrical system, use the two low voltage legs (check each
leg to ground to insure the low voltage legs are used). Using the high voltage leg will cause
the machine to malfunction. In some locations, the power supply may have only one 230 volt
hot leg. If so, ensure the hot leg goes to the L1 contactor in the electrical box.
C. This unit will not work properly if there is more than a 10V voltage drop in the power supply line
between the power source and the machine. A drop of more than 10V indicates undersized
wiring or excessively long runs.
D. The unit must be installed on a "single branch" circuit (on a circuit by itself), protected by 30Amp
service and a 30 Amp fuse (or circuit breaker).
E. It is recommended that a 3 conductor, 30 Amp receptacle (NEMA #L-630-R) be used. Using a
voltmeter, check voltage across both "hot legs" (240VAC) and between ground and each "hot
leg" (120VAC) to ensure proper wiring and voltage (see Figure 4.1).
F. Remove the plug from the power cord and feed the cord through the strain relief located at the
back of the unit. Tighten the strain relief securely. Reinstall the plug on the power cord and
check for continuity on the plug across both "hot legs" and no continuity between each "hot leg"
and ground (see Figure 4.2).
G. Do not connect the unit to power at this time.

5. CONNECTING WATER, CO2, AND SYRUP SUPPLIES
5.1 WATER SUPPLY
IMPORTANT
A WATER PUMP AND WATER REGULATOR ARE INSTALLED IN THE BASE OF THE MACHINE.
A WATER FILTER SHOULD BE INSTALLED IN THE WATER LINE BEFORE BEING
CONNECTED TO THE MACHINE. FLUSH THE FILTER WITH SEVERAL GALLONS
(12-15 LITERS) OF WATER PRIOR TO USE TO INSURE BLACK CARBON "FINES" ARE NOT
FED INTO THE FREEZING CHAMBER.
3
Figure 5.1
CAUTION:
THE BACKFLOW PREVENTION DEVICE (FBD PN 12-2272-0001) MUST HAVE A DRAIN LINE
CONNECTED TO THE VENT (SEE FIGURE 5.1). THIS IS REQUIRED TO DRAIN AWAY WATER
IN THE EVENT OF A BACKFLOW SITUATION OR A FAILURE OF THE BACKFLOW DEVICE.
FAILURE TO DO SO MAY RESULT IN FLOODING OF THE ESTABLISHMENT.
NOTE:
Water pipe connections and fixtures directly connected to a potable water supply shall be sized,
installed, and maintained in accordance with federal, state and local codes.
A. Connect the backflow prevention assembly to the water inlet of the unit (see Figure 5.1). The
backflow prevention assembly is provided with the unit.
B. Fabricate a 3/8 inch supply line for connecting the unit to a potable water supply (a 3/8” barb by
1/4” flare nut fitting will be required).
C. Install a shutoff valve in the water line as close to the unit as practical and convenient. The use
of a water filter is recommended.
D. Clear the line by running a minimum of two (2) gallons (7.57 liters) of water through the line
before attaching the line to the unit.
E. Connect the line to the bulkhead fitting labeled "WATER IN" located at the rear of the unit (see
Figure 5.2).
F. Do not turn water on at this time.
5.2 CO2SUPPLY
NOTE:
The CO2supply may come from either an independent tank/regulator or a bulk CO2system. If
connected to a bulk CO2system, ensure the bulk regulator is set at 115 to 120 PSIG (793.5 to
828.0 KPa)] and install a shutoff valve and a secondary supply regulator [to be set at 70-72 PSIG
(482.6-496.4 KPa)] in the line. Ensure that the CO2line comes directly from the main branch
on the bulk supply and is not branched off down line. Failure to do so may starve the unit
of CO2flow and cause performance problems.
A. Fabricate a 3/8 inch supply line for connecting the unit to a CO2supply.
B. Connect the supply line to the CO2bulkhead fitting labeled "CO2IN" located at the rear of the
unit (see Figure 5.2). A 3/8” barb by 1/4” flare nut fitting will be required to make connection.

If Figal tank will be utilized, splice a barb "cross" into the CO2supply line and run three (3) lines
to tank location and install CO2tank couplers to end of lines.
D. Do not turn on the CO2at this time.
5.3 SYRUP SUPPLY
The unit may be connected to either a BIB (Bag-in-Box) or a five-gallon syrup supply (figal). Use
the appropriate connection method below.
NOTE
Installations requiring long runs of tubing [25 feet or more (7.62 meters)] may encounter pressure
fluctuation problems. The machine's sensors may indicate that the machine is out of syrup, water,
or CO2. To avoid pressure fluctuations, consider the following solutions.
A. Increase the tubing size to 3/8 inch diameter.
B. Install booster pumps in the supply lines. Use a vacuum regulating valve with syrup booster
pumps.
C. Increase primary CO2regulator pressure from bulk or tank CO2to 105 - 120 PSIG (723.9 to
828.0 KPa). A secondary regulator WILL be necessary for syrup pumps to avoid exceeding
manufacturer’s recommended operating pressures. Set the secondary regualtor to 70-72 PSIG
(482.6 to 496.4 KPa).
BIB SUPPLY
A. Fabricate three (3) 1/4 inch supply lines for connecting the unit to the syrup pumps.
B. Connect the lines to the bulkhead fittings labeled "SYRUP LEFT", "SYRUP CENTER" and
"SYRUP RIGHT" located at the rear of the unit (see Figure 5.2).
C. Do not turn on the CO2at this time.
FIVE GALLON (FIGAL) TANK SUPPLY
A. Fabricate three (3) 1/4 inch supply lines for connecting the unit to the syrup tanks.
B. Connect the lines to the bulkhead fittings labeled "SYRUP LEFT", "SYRUP CENTER" and
"SYRUP RIGHT" located at the rear of the unit (see Figure 5.2).
C. When using five gallon (figal) syrup tanks, a Syrup Restart Valve (SRV) and tank couplers
must be used on each line. Warranties will be void if an SRV is not installed.
1. The "OUT OF" devices in the machine will not function properly without the use of a Syrup
Restart Valve. If the "OUT OF" devices do not function, the machine will supply only water
to the product cylinder and it will freeze up.
2. When replacing a figal, insure that the syrup line to the dispenser is attached to the figal
before the CO2line is attached to the figal. This will allow the SRV to work properly.
3. To operate the SRV, press the restart button after syrup tank is changed. The red light
beside each chamber will then go out and product will refreeze.
D. Do not turn on the CO2at this time.
6. STARTING THE UNIT
6.1 INITIAL POWER-UP
A. Insure the electrical power is disconnected from the
unit.
B. Open front marquee door, if installed, by firmly
pulling back at the bottom and rotating up and over.
C. Using a Phillips head screwdriver, remove the
stainless steel access panel located below the
keypad.
D. Remove the splash plate and electric box cover
(see Figure 6.1).
E. Plug unit in to the electrical power. Check for the display of information on the LCD control panel
(this will read "COPYRIGHT" on bottom line of LCD display).

6.2 BRIXING
A. With the unit powered up, press both of the "OFF" buttons on the display to ensure the unit is
in the OFF state.
CAUTION
CHECK ALL SUPPLY LINES TO INSURE THAT THEY ARE CONNECTED TO THE CORRECT
FITTINGS. IF LINES ARE NOT CONNECTED PROPERLY, COMPONENTS WILL BE DAMAGED.
B. Open the water supply valve and check all water line connections for leaks.
C. Connect the BIB connectors, or the syrup and CO2couplers, to figal tanks. Check all syrup
supply connections at the rear of the machine for leaks
D. Open the CO2tank valve and adjust the primary tank regulator until the "CO2Pressure"
readout in the "SERVICE MENU\ READOUTS\ COMMON READOUTS" reads 70-72 PSIG
(482.6 KPa to 496.4 KPa). Check all CO2line connections for leaks.
E. Adjust the CO2secondary regulator (located inside the machine) to read 28-32 PSIG (193.2 to
220.8 KPa) according to the LCD readout found in the "REGULATED CO2" readout in the
"SERVICE MENU\ READOUTS\ COMMON READOUTS" section of the LCD menu.
IMPORTANT!
SET ALL PRESSURES USING THE LCD READOUTS ON THE UNIT - NOT BY THE GAUGES
ON THE REGULATORS!
F. Close Syrup flow controls by backing (counter-clockwise) controls all the way out (see Figure
6.4).
G. Using water only, check the flow rate (through the sample valve) and set water flow to provide
aflow of 15 ounces in 10 seconds using a graduated container. Do this for both left and right
side flow controls. Turn control adjustment screw clockwise to increase flow or
counter-clockwise to decrease flow.
H. Pre-set Syrup flow by turning in Syrup flow controls four (4) turns (clockwise).
I. Place a container under the sample tube and fully depress the sample valve until a good water
and syrup mixture is obtained. Sample tube is located inside unit. This sample should be
discarded.
J. Place a sixteen (16) ounce (0.473 l) cup under sample tube and fully depress the sample valve
until 9 - 12 ounces (0.266 - 0.355 liter) have been dispensed into cup.
L1
L2
F. With voltage meter, check voltage at contactor between L1 & L2 and record. Also check
between L1 and ground bar, and between L2 and ground bar, to ensure highest voltage leg is
on L1 (see Figures 6.2, 6.3, and Section 14.3).
H. Access the “Line Voltage” readout in the "SERVICE MENU\READOUTS\COMMON
READOUTS" section of the LCD menu. If the “Readout” voltage is more than two (2) volts
different than the voltage across L1 and L2, the "Voltage Offset" must be changed.
Failure to do so will cause performance loss of the unit. To change the "voltage offset", go to
"SERVICE MENU\MACHINE SETTINGS\COMMON SETTINGS" and enter the difference
between the meter reading and the “Line Voltage” readout to make the LCD voltage reading
match the L1 and L2 voltage. Reinstall the splash plate and electric box cover.

K. Measure the brix with a refractometer. Set brix to between 13.5 and 15.0 by adjusting the syrup
brix flow controller clockwise to increase brix level or counter-clockwise to decrease brix level.
If the brix requires adjustment, discard a sample before checking the brix again.
NOTE
Do not adjust the brix with the water flow control setting unless you are unable to obtain the
desired brix with adjustments to the syrup flow control.
Brix reading is affected by temperature. Samples taken from the chamber should be at the
same temperature as from the sample valve.
L. Repeat steps I, J, and K for other side and center.
6.3 FILLING THE CHAMBER
A. Access "CO2SOL" by going to the "SERVICE MENU\MANUAL ON/OFF" section of the service
menu.
B. Displace the air in the chamber with CO2by activating the CO2solenoid.
1. Pull and hold the relief ring until the escaping, rushing air sound almost stops; then release
the ring. Allow the pressure to rebuild in the tank.
2. Repeat this procedure at least two more times until the air has been displaced by the CO2.
Remember to deactivate the CO2solenoid upon completion.
C. Repeat stepsA and B above for the center and right side of unit. Remember to deactivate the
CO2solenoid upon completion.
D. With CO2in the chamber, press the left side "FILL" button to begin filling the chamber with prod-
uct. If the chamber does not fill, gently pull the Relief Ring until filling begins and then release.
As the chamber fills, the pressure in the chamber will increase until it rises above the PSI fill
point. At this point, the chamber will stop filling and the LCD will readout "Fill Hold". It will then
be necessary to pull the relief ring to relieve the pressure and allow filling to continue. Slowly
pull the relief ring until the pumps activate, then release. Repeat the venting process until the
chamber is 90% full (level with relief valve), then press Fill button to turn OFF.
Fill one (1) chamber at a time.
E. Repeat steps A, B, C, and D for the center and right chambers.
F. Press the "DEFROST" and then the "RUN" buttons for all barrels to begin the freezing process.
The beater motors will begin to run but the compressor will wait for two (2) minutes before
starting. After the two (2) minute waiting period, the machine will defrost and then begin the
freeze cycle.
G. After an initial freeze down [approximately ten (10) to twelve (12) minutes], the product will be
frozen and ready to dispense.
NOTE
On an initial freeze down, products must be given adequate time to absorb CO2. Until CO2is
properly and adequately absorbed, drinks could be too "wet" or too "heavy". If adjustments are
necessary, refer to section 9.
H. Re-check CO2, Water, and Syrup lines for leaks.

Figure 6.4

CRITICAL REGULATOR AND FLOW CONTROL SETTINGS
SET ALL PRESSURES USING THE LCD READOUTS ON THE UNIT - NOT BY THE GAUGES ON THE
REGULATORS!
CO2PRIMARY REGULATOR The CO2Primary Regulator MUST BE SET TO 70-72 PSIG (482.6
TO 496.4 KPa) [bulk tank set at 115-120 PSIG (793.5 - 828.0 KPa)].
CO2SECONDARY REGULATOR The CO2Secondary Regulator SHOULD BE SET AT 28-32 PSI
(Secondary Regulator) (193.2 TO 220.8 KPa) STATIC PRESSURE.
The CO2Secondary Regulator is on the header assembly which is
behind the access panel. This regulator is a “non-vent” regulator. This
means that if you lower the regulator setting, you will need to dispense
drinks (with “Fill” activated) until cylinder begins to refill before the new
setting will register on the gauge.
FLOW CONTROLLERS WATER FLOW MUST BE SET TO PROVIDE A FLOW OF 15
OUNCES IN 10 SECONDS BEFORE ADJUSTING THE BRIX. BRIX
MUST BE SET BETWEEN 13.5 -15. Flow controllers are on the
header assembly. A sample may be taken by fully depressing the
sample valve while "FILL" is in the "OFF" position.

2. Each button operates a double acting switch. Pressing the button once activates the
process. Pressing the button a second time deactivates the process. Take care not to
double press the buttons when first activating a process.
The RUN button initiates the freeze process. After pressing this button, the
beater motors will run for two minutes before the compressor starts. This
delay eliminates the possibility of "short cycle" damage to the compressor.
Run also maintains the flow of product into the chambers when needed.
The OFF button turns off all the machine's refrigeration and chamber refill
systems. All of the electronic controls are still active.
