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 (CO

2)

•CO2 (carbon dioxide) displaces oxygen. Strict attention must be observed in the prevention of CO2
gas leaks in the entire CO2 and soft drink system. If a CO2 gas leak is suspected, immediately
ventilate the contaminated area before attempting to repair the leak. Personnel exposed to high
concentrations of CO2 gas will experience tremors which are followed rapidly by loss of conscious­ness and suffocation.

• To avoid personal injury and/or property damage, always secure CO

2 cylinders in an upright position

with a safety chain to prevent cylinders from falling over. Should the valve become accidentally
damaged or broken off, a CO

2 cylinder can cause serious personal injury.

2. RECEIVING AND UNPACKING UNIT

Figure 1.1

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

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

Ground

Continuity

Figure 4.1

Figure 4.2

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,

a 10% 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 volt age 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 30 Amp

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.

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 CO

2 SUPPLY

NOTE:

The CO2 supply may come from either an independent tank/regulator or a bulk CO2 system. If
connected to a bulk CO2 system, 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 CO

D. Do not turn on the CO2 at 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 CO

2 regulator pressure from bulk or tank CO2 to 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 CO

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 CO

2 line 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 CO

2 at this time.

A. The electronic machine controls are designed to provide a logical sequence of operation with a

minimum of written instruction. System operating parameters are selected and set from a
menu.

B. LEFT, CENTER, and RIGHT Buttons (see Figure 7.1).

1. Each barrel has five (5) active buttons. They are labeled FILL, BEATER, RUN, DEF
(defrost), and OFF.

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

RUN

beater motors will run for two minutes before the compressor starts. This
delay eliminates the possibility of "short cycle" damage to the compressor.

OFF

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.

Figure 7.1

BEATER

The BEA TER button activates the beaters inside the freezing chambers. The
beaters can be activated to mix the slurry.

NOTE:

The beaters start automatically when the RUN or DEF buttons are pressed.

The DEF button allows the user to manually defrost chamber. Because the
unit automatically defrosts during the day, it is not necessary to defrost

DEF

manually. However, this button provides the option to do so if desired. If the
defrost is manually activated, the unit will return to the previous mode (after
completion of the defrost).

NOTE:

If the machine is in the "OFF" state when the DEF button is pushed, there will
be a two (2) minute delay before the compressor starts.

The FILL button activates the solenoid valves that allow product to flow into

FILL

the freezing chambers (providing the pressure in the barrel is low enough to
allow a fill). Each chamber should be filled to 90% of chamber capacity (level
with the relief vent valves) prior to start-up.

C. Common Controls and Displays

1. The four (4) control buttons, located below the LCD display, allow access to the various
menu levels for the machine (see Figure 7.1).

CANCEL

BACK

FWD

The CANCEL button cancels any current operation and steps the operator
back one (1) level in the menu.

The BACK button steps the operator backwards within the current level. This
button also allows the operator to decrease or lower values (numbers).

The FWD button steps the operator forward within the current level. This
button also allows the operator to increase or raise values.

The SELECT button allows the operator to enter changes in the unit

SELECT

programming and it also allows the operator to move into different levels in
the menu.

2. The LCD display screen in the center of the control panel allows the operator access to unit
status, settings, and operational information (see Figure 7.2). The screen is divided into
four (4) sections. The upper portions of the screen display the current status of each cham­ber. The lower half of the screen displays a mode that can be changed or monitored.

D. Explanation of the Menu Structure (See Figure 7.3)

1. Access to the control panel is separated into two (2) levels. These levels have been

established to make certain information available to the operators and other information
available to service personnel.

Level One This CUSTOMER MENU level is designed for the machine operator at the

store level. The store operator should only access this level of information,

and should NOT access or make changes in the SERVICE MENU without
prior authorization and approval.

Level Two The SERVICE MENU has been established for the use of authorized service

technicians ONLY. This level provides access to all setup values that will

E. How to Access and Change Values

The same procedure for changing values applies to all access levels. The following steps allow
the parameters of the control system to be monitored and changed.

1. The current mode is displayed in the lower half of the LCD. Press the FWD button to step
to the next mode. Continue pressing the FWD or BACK button until the desired mode is
displayed. When the desired mode is displayed, press SELECT to enter the mode.

2. To make changes to the displayed mode, press the SELECT button. When a value in the
lower half of the display begins to flash, this indicates that the value can be changed.

3. To change the value, press the FWD button to increase the value or the BACK button to
decrease the value. Any on/off functions can be changed by pressing the SELECT button.

4. Once the desired value is displayed, press the SELECT button to enter the value into the
computer. Pressing the SELECTbutton will stop the display from flashing. When the value
stops flashing, it has been changed.

NOTE:

When entering TIME, WAKE, or SLEEP functions, both the hours and minutes must be
selected before the computer will accept the change. For the Defrost Times, days in upper
case (capitals) are selected. Days in lower case are NOT selected.

8. CLEANING AND SANITIZING THE UNIT

8.1 GENERAL INFORMATION

The following cleaning and sanitizing procedures pertain to the FBD equipment identified by this
manual. If other equipment is being cleaned, follow the guidelines established for that

equipment.

A. FBD equipment (new or reconditioned) is shipped from the factory, cleaned and sanitized in

accordance with NSF guidelines. After installation is complete, the operator of the equipment
must provide continuous maintenance as required by this manual and/or state and local health
department guidelines to ensure proper operation and sanitation requirements are maintained.

B. Cleaning and sanitizing should be accomplished only by trained personnel. Sanitary gloves are

to be used during cleaning and sanitizing operations. Applicable safety precautions must be
observed. Instruction warnings on the product being used must be followed.

NOTE

13

C. Water lines are not to be disconnected during the cleaning and sanitizing of syrup lines to avoid

contamination.

D. Do NOT use strong bleaches or detergents. They tend to discolor and corrode various

materials.

E. Do NOT use metal scrapers, sharp objects, steel wool, scouring pads, abrasives, solvents, etc.,

on the dispenser.

F. Do NOT use hot water above 140°F (60°C). This may damage certain materials.

8.2 REQUIRED CLEANING EQUIPMENT

A. A mild soap solution (for example, Ivory Liquid, Calgon, etc.) mixed with clean, potable water at

a temperature of 90 to 110°F (32 to 44°C) should be used to clean the external components of
the equipment. Any equivalent mild soap solution may be used as long as it provides a caustic
based, non-perfumed, easily rinsed mixture containing at least two (2) percent sodium
hydroxide (NaOH). Rinsing must be thorough and use clean, potable water which is also at a
temperature of 90 to 110°F (32 to 44°C).

B. Sanitizing solutions should be prepared in accordance with the manufacturer's written

recommendations and safety guidelines. Any sanitizing solution may be used as long as it is
prepared in accordance with the manufacturer's written recommendations and safety guide­lines, and provides 200 parts per million (PPM) available chlorine. Sanitizing solution is to be
purged from line(s) and equipment by flushing with product only until there is no after taste. Do

not rinse with water.

NOTE

Please note that a fresh water rinse cannot follow sanitization of equipment. Purge only with
the end use product until there is no after taste in the product. This is an NSF requirement.

8.3 DAILY CLEANING OF THE UNIT
CAUTION

DO NOT USE ABRASIVE TYPE CLEANERS.
A. On a daily basis, or more often if necessary, wash all exterior surfaces of unit with a mild soap

solution. Rinse with clean water. Wipe dry with a clean soft cloth.

B. Remove and wash drip tray in mild soap solution. Rinse with clean water. Reinstall drip tray on

unit.

8.4 SANITIZING THE SYRUP SYSTEMS

The unit should be sanitized every 90 days. Prepare a chlorine solution (less than pH 7.0) containing
500 PPM available chlorine with clean, potable water at 90°F to 100°F (Note: 500 PPM is five (5) times

stronger than the usual recommended 100 PPM. This is required because the sanitizing solution will be
diluted with four (4) parts water when it enters the barrel). Any sanitizing solution may be used as long as

it is prepared in accordance with the manufactures safety guidelines and provides 500 PPM available
chlorine." The following procedure takes about one (1) hour.

A. Press the "OFF" button, followed by the "DEF" button, for all three chambers. Remember, there

will be a two (2) minute delay before the unit begins defrosting.

B. After defrost, activate the left, center and right CO

2 solenoids by going to the "SERVICE

MENU/MANUAL ON/OFF" section of the menu.

C. Place a container under the valve and empty the barrels. Activate the beaters to facilitate the

removal of product.

D. Disconnect the BIB connectors from the syrup boxes and install BIB adapters (FBD

PN 05-0249) onto the BIB connectors. Activate the right, center, and left solution solenoids at
the "SERVICE MENU/MANUAL ON/OFF" section of the service menu until all syrup has been

evacuated from the lines. Purge barrel of product as necessary.
E. Turn off the solution solenoids and drain the barrels again.
F. Turn off the CO

2 solenoids and beaters after the barrels are empty.

G. Relieve pressure by opening valves. Remove the faceplate to drain out excess product.

Replace the faceplates.
H. Prepare five (5) gallons of sanitizing solution BUT ADD FIVE (5) TIMES THE AMOUNT OF

SANITIZER CONCENTRATE THAT THE SANITIZER MANUFACTURER RECOMMENDS.

This is required because the solution will be diluted at about 4:1 in the barrel.

temperature should be 110 to 115°F (44 to 46°C). If using a powder, stir the solution until

the sanitizing agent has completely dissolved.

14

The water

I. Drop the BIB connectors (with adapter) into the sanitizing solution.
J. Activate the right, center, and left solution solenoids at the "SERVICE MENU/MANUAL

ON/OFF" section of the service menu.

K. Fill each chamber approximately 2/3 full with sanitizing solution/water mixture, then deactivate

the solution solenoids.

L. Activate the CO

Once the chambers are evacuated, deactivate the CO2 solenoids and purge the pressure from
the cylinders by pulling the faceplate relief valve.

M. Activate the solution solenoids again and fill the chamber to fill to ½ full of sanitizing solution.

Deactivate the solution solenoids and turn on the beaters. Let solution agitate for three (3)
minutes.

N. Activate the CO

beaters and CO2 solenoids, and purge pressure from the chambers.
O. Remove sanitizing adapters from the BIB lines and reconnect the lines to the syrup supplies.
P. Partially fill the chambers (1/2 full) with syrup and water by activating the solution solenoids.

Turn off the solenoids. Run the beaters for a few seconds.
Q. Drain the product by activating the CO
R. Partially refill the chambers again and test the product for off taste. Repeat the drain/fill process

until no off taste exists.
S. When there is no more off taste, fill the unit following the procedure outline in section 6.3 and

restart.

REMOVE SANITIZING SOLUTION FROM DISPENSER AS INSTRUCTED. RESIDUAL
SANITIZING SOLUTION LEFT IN THE SYSTEM COULD CREATE AHEALTH HAZARD.

9. BASICS OF OPERATION

2 solenoids and evacuate the solution from the chambers while running beaters.

2 solenoids and evacuate the sanitizing solution from the cylinders. Turn off

2 solenoids.

CAUTION

NOTE

On an initial freeze down, products must be given adequate time to stabilize. Making adjustments too
quickly may negatively affect drink quality.

9.1 MAKING ADJUSTMENTS TO THE FBD553D

A. In order to produce a consistent, quality beverage with the FBD553D Frozen Beverage Machine,

there are a few critical settings that must be maintained. These settings are preset when you

receive the machine from the factory, but, due to variations that occur (e.g., in operating

environments, syrups, and individual machines, etc.), it may be necessary to make minor

adjustments to these critical settings. Adjustments are easily made using the keypad located

behind the door at the front of the machine, or by adjusting the CO

2 regulator located behind the

access panel below the keypad.
B. The settings that control product quality and production rate are:

1. Beverage Syrup Content or Brix Level (Set on Volumetric Valve)

2. Chamber “Level Control”

3. Regulated CO

2 Injection Pressure

4. Freeze and Thaw Settings

C. In Sections 6 and 7 of this manual are instructions on machine installation and initial operation.

These instructions should be followed for initial setup of the machine. If the product quality is

not as desired after allowing time for stabilization, the critical settings should be checked and

adjusted as necessary . The following sections discuss the sequence and method to verify these

settings. These four (4) critical settings are explained here to help better your

understanding of how the machine operates so you can make adjustments, if necessary.

1. Adjusting the Brix Level
a. Consistent, high quality beverages require adjusting and maintaining the syrup content

of the drink or brix level between 13.5 and 15. Abrix level lower than 13.0 may cause
operational problems. A low brix level (lower than 13.0) will produce a weak tasting
drink and tends to freeze product around the beater shaft. Ahigh brix level (higher than

15.0) causes freezedown times to be longer and produces a more liquid drink. The

water flow rate must be set to provide a flow of 15 ounces in 10 seconds prior to adjusting brix.

15

2. “Level Control”
a. The FBD553D frozen beverage dispenser utilizes a proprietary liquid level control

system (patented) to hold a constant liquid level. A constant liquid level assures a
quality frozen product.

b. If a more “wet” product is desired, the numerical setting (0-6) should be increased. If a

“drier” and colder product is desired, the numerical setting should be decreased.

c. The default value set at the factory is 3. This setting should produce an excellent

quality product. (See Section 10 for instructions on changing settings.)

3. Regulated CO
a. The CO

2 Injection Pressure

2 injection pressure is set by adjusting the secondary regulators, located behind

the access panel below the control panel in the front of the machine. The left regulator
feeds the left and center barrels and the right regulator feeds the right barrel. The CO2
regulators should be set at 28-32 PSIG (193.0 to 220.8 KPa). The unit then
automatically sets the chamber pressure between 25 and 30 PSIG (172.5 and

206.8 KPa).

Some "citrus based syrups" have been shown to produce a better quality drink with a
lower chamber pressure. However, lowering the "Regulated CO2 regulator" will affect
both left and center chambers. For adjusting individual chamber pressures, refer to
Section 10.

4. Thaw and Freeze Settings
a. The Thaw and Freeze settings signal the refrigeration system when to start freezing and

when to stop freezing. The liquid in the chamber freezes until it reaches the desired
frozen consistency; then the refrigeration system shuts off and the chamber begins to
thaw. The liquid continues to thaw until it reaches a consistency specified by the Thaw
value. The Thaw value is the point at which the refrigeration system turns back on and
refreezes the product. This assures the product is maintained in a good acceptable
quality frozen drink range.

b. Prior to changing any Thaw or Freeze settings, make sure the brix and water flow rate

are correct and the liquid level control settings are properly set. Also assure the
chambers stay filled to the proper levels with the proper amount of CO

frozen drink temperature is 24 to 28°F (-4.4 to -2.2°C) and should be checked prior
to making any adjustments. (See Section 10 for instructions on changing settings.)

CAUTION

IF THE THAW - FREEZE IS SET AT A LOWER SETTING, COMPRESSOR “SHORT
CYCLE” CAN OCCUR THAT WILL CAUSE THE COMPRESSOR TO OVERHEAT. IF A
LOWER SETTING IS USED, THE DISPENSER OPERATION MUST BE MONITORED TO
INSURE THE COMPRESSOR DOES NOT “SHORT CYCLE”.

c. The Thaw and Freeze settings may be raised or lowered to change the temperature of

the product. A default setting of 3 is set at the factory. To decrease the temperature,
decrease the numerical setting to 2 or 1; to increase the temperature, increase the
numerical setting to 4 or 5.

10. CHANGING FACTORY SET “LEVEL CONTROL”

NOTE

2. The optimum

Always check brix, Regulated CO2 setting, and water flow rates before adjusting “Level Control”.
The factory setting of the liquid “Level Control” may be changed to alter the consistency of the product.

Adjusting the liquid “Level Control” will change a drink that is too liquid or one that is frozen too hard.
A product that is frozen too hard will not allow the chamber to stay full and the drink will dispense with
sudden releases of CO

2 (“spitting”). A“too full” chamber may cause a “too wet” drink.

10.1 BEFORE CHANGING “LEVEL CONTROL” SETTINGS

A. Each machine ships with preset level control values. These values should be correct for

normal operation of the machine and should not have to be modified.

NOTE

16

B. Before making any changes to the level control settings, defrost all three chambers by

pressing the “DEF” buttons located on the control panel. The machine may
automatically correct any problems with drink quality after going through a defrost cycle.

C. After the defrost cycle, the compressor may cycle on and off several times to ensure that the

product is uniformly frozen. Wait several minutes before judging the quality of the product.

D. If factory level control settings are correct, the product should freeze, thaw and then refreeze to

an acceptable consistency range. Remember, drinks poured directly after a freeze cycle will

appear more frozen than the last drink poured before the unit begins to refreeze the cylinder.

E. The level control settings of each drink chamber are preset to a default value of 3. If the

corresponding secondary regulator inside the unit is properly set to 28-32 PSIG (193.0 to

220.8 KPa), the chamber pressure will be “set” automatically.

F. After the machine is installed and each chamber is properly filled, press the “DEF” button on the

control panel to allow the machine to automatically “baseline”. Baselining indicates to the
machine that the chamber contains liquid. As a result, the machine sensors determine how
much to freeze the product.

G. The display will flash “DEFROSTING” until baselining is complete. The machine will

automatically start running if the machine was running when the defrost cycle was started. If the
machine was not running before the defrost cycle started, the “RUN” button must be pressed.
Note that there may be a delay of up to two (2) minutes before the machine turns on after the
“RUN” button is pushed. This delay is normal. Do not press the “RUN” button again or press

any other buttons until the machine starts.

10.2 DRINK TOO HARD AND COLD

A. If the drink is too hard and cold or the chamber is not full, adjust the “level control” to a higher

level setting. Use the recommended settings that follow to properly adjust the liquid level
control settings.

B. It will be necessary to drain off several drinks to allow the chamber to fill and rebalance. It is

also then necessary to defrost the chamber and allow the product to refreeze. If the drink is still
too hard, repeat the process taking the level control setting to the next higher value.

10.3 DRINK TOO LIQUID

A. If the drink is cold, but is still a liquid, adjust the level control to a lower level setting. Use the

recommended settings that follow to properly adjust the level control.

B. It will be necessary to drain off several drinks to allow the chamber to fill and rebalance. It is

then necessary to defrost the chamber and allow the product to refreeze. If the drink is still too
liquid, repeat the process taking the level control to the next lower setting.

C. If the product is still too liquid, it may be necessary to adjust the THAW-FREEZE beater settings.

Refer to Section 11 (Changing Factory Thaw and Freeze Settings).

D. Drink temperature should be between 24°F and 28°F (-4.4°C to -2.2°C).

NOTE

If "Wet" or "Dry" drinks are common to all three chambers, adjust "Regulated CO2" up to
lighten drink or down to make drink wetter before adjusting level controls!

If the machine continues to yield a drink that is too liquid or too hard after changing level control
settings, it may be necessary to adjust the THAW and FREEZE settings (refer to Section 11,
Changing Factory Thaw And Freeze Settings).

11. CHANGING FACTORY THAW AND FREEZE SETTINGS

11.1 BEFORE CHANGING THAW AND FREEZE SETTINGS

A. Each machine ships with THAW and FREEZE values preset. These values should be correct

for normal operation of the machine and are designed to produce a drink temperature
between 24 and 28 degrees. Before making any changes to THAW AND FREEZE
settings, check drink temperature. If drink temperature is within correct range, DO NOT
CHANGE THAW-FREEZE SETTINGS.

B. Before changing the THAW or FREEZE settings, verify that the level control and Brix settings

are properly set. After verifying the “Level Control”, defrost both chambers by pressing the
“DEF” buttons located on the control panel. The machine may correct any problems with drink
quality after going through a defrost cycle.

1. After the defrost and refreeze cycle, the compressor may cycle on and off several times to
ensure that the product is uniformly frozen. Wait several minutes, and dispense several

drinks, before judging the quality of the product.

2. The product should freeze to a proper frozen texture, thaw, and refreeze to the same
general texture. The compressor turns on when the thawed product requires refreezing and
shuts off when the product is frozen enough.

3. If the product is freezing too cold (below 24°F), the THAW - FREEZE value may be
increased. If the product is not cold enough (above 28°F), the THAW - FREEZE value may
be decreased. Use the recommended settings that follow when making adjustments to the

THAW - FREEZE value.

Recommended THAW-FREEZE Settings

Figure 11.1

11.2 CHANGING THAW AND FREEZE SETTINGS

The THAW-FREEZE values should only be changed if the drink quality is not as expected. Use the
following steps to change THAW-FREEZE settings as necessary. Before changing the
THAW-FREEZE settings, verify that the brix and level control settings (see Section 10.1) are
properly set. THAW-FREEZE settings may not need changing if corrections are made to the level
control settings.

A. Changing the THAW-FREEZE Settings

1. Access the service level by pressing the “FWD” button on the control panel until the
“SERVICE MENU” displays. Press the unmarked button on the center barrel, “MACHINE
SETTINGS” displays.

2. Pressing the “FWD” button scrolls through the left, center, and right setting options.

3. Press “SELECT” (on the barrel you wish to change) and “Level Control” displays.

4. Press the “FWD” button until “THAW-FREEZE” displays.

5. To change the THAW-FREEZE values, press “SELECT” and the number starts to flash.

6. Press “FWD” to change to a higher setting or press the “BACK” button to change to a lower
setting.

7. Once the desired setting displays, press “SELECT” to save the new value.

8. Press “CANCEL” and “L SIDE SETTING” displays.

9. To change the other chambers, press “FWD” until “R SIDE SETTINGS” or
C SIDE SETTINGS” displays. Repeat Steps 3-7 above.

10. When settings are complete, press the “CANCEL” button until “Copyright” displays.

12. BEVTRAK OPERATION

Bevtrak is a feature on the FBD553D that enables the unit to dial a toll free number every night and
download current status information about the unit as well as daily sales numbers. The information is
collected and cataloged on the FBD server and is readily available to subscribers via the Internet. The
data available for viewing is:

• Sales totals for each barrel in daily, weekly or monthly periods

• Number of units not reporting in

• Number of machines currently in an "out of" state

• Number of machines in an "error" state

• Total of hours in a "product out" state
Additionally, all machine settings can be viewed by qualified personnel to aid in trouble shooting problems

remotely.

12.1 NAVIGATING THE BEVTRAK MENU

A. To access the Bevtrak menu, press the "FWD" button on the control panel until the "SERVICE

MENU" appears. Press the unmarked button on the center barrel panel group. "MACHINE
SETTINGS" displays. Press the "FWD" button repeatedly until "BEVTRAK" appears. Press
"SELECT" to enter the Bevtrak menu. See figure 7.3 for a layout of the FBD553D menu
structure.

B. The following selections are in the Bevtrak menu:

: MM/DD/YY HH:MM:SS - The next time the unit is scheduled to call the home server.

CT
Display Modbus error = 1 - A value of 1 displays "MODBUS ERROR" when the modem sends

a bad "packet" of information due to static on the telephone line. Avalue of 0 does not show
a modbus error. Note: This does not mean the call was a failure, the unit will re-send the
data.

12.2 NORMAL OPERATION

A. In automatic mode (Bt manual = 0), the unit will place a call when it is scheduled. If the unit

finds the phone line is busy, it will hang up and wait the retry interval (Ret inv m) and then try to
place the call again. If the call does not finish within the timeout period (Timeout m), the unit will
hang up and wait the retry interval to try again. It will keep trying for the number of times in the
retry times value. Once the call connects to the server, the unit will exchange user name and
password information with the server. The server will then request data from the unit and send
information to the unit. One of the things the server sends is the recall time. The unit will use
this time to reschedule the next call if in auto mode. In manual mode, it will use the call period.
When completed, the server will send a hang up command to the unit. They will both hang up
and wait until time for the next call.

B. The server will reschedule the next call to fall in the window of midnight to 5 AM local time to the

unit. This is based on the unit's time of day clock. The data collected is processed at 6 AM and
posted on the Bevtrak web site.

C. To access the data on the Internet, you must be a subscriber, and have a user name and

password assigned to you. You will then be able to view only the data from units you own or
manage.

D. Each unit is assigned a unique serial number. That serial number is entered into the machine

during final test. It is by this serial number that the Bevtrak server knows to whom the unit data
belongs to.

E. During a successful call, the display will show the following sequence:

1. Bevtrak calling (placing a call)

2. Modem connected (the unit has found the server modem)

3. Bevtrak online (user name and passwords have been exchanged)

4. Bevtrak shutdown OK (the server has sent a shutdown command)

5. Bevtrak call done (ready to place the next call at the scheduled time)

13. CRITICAL INFORMATION

(Bevtrak call period) - This the time between calls when in the manual mode.

(Call delay minutes) - The delay in minutes from when Bevtrak is enabled till

The following information is critical to proper machine operation. Prior to troubleshooting problems with
the unit, review the following information.

13.1 DEFROST AND RUN TIME DELAY

When either the RUN or the DEF button on the control panel is pressed, the message
“RUN BEATER” or “DEF BEATER” is displayed. This is a time delay before the compressor starts
running. The delay can be as long as two (2) minutes before the unit starts running or defrosting.
Do not press the buttons again. Wait, and the machine will start defrosting, then freezing.

13.2 CHAMBERS 90% FULL ON INITIAL SET UP

Before beginning a RUN-FREEZE cycle, the chambers should be filled approximately 90% full (up
to relief valve). If the chambers are above the 90% level, with Fill Off, open the dispensing valve
and allow a small amount of liquid to drain out. If the chambers are not 90% full, press “OFF”, then
“FILL”, and then slowly pull the vent ring on the faceplate to vent gas, and allow liquid to fill. The

20

screen will display “Filling”. Fill slowly and do NOT let the pressure drop more than three to four

(3-4) PSI.

13.3 LINE VOLTAGE DROP

The unit requires a separate electrical circuit complete with a 30 AMPbreaker or fuse on a 30 AMP
service. The unit will not function properly if the line voltage drops more than 10 volts between the
power source and the machine.

13.4 LONG TUBING RUNS

A. Long runs of supply tubing can cause problems if the pressure drop (between the CO

syrup source and the unit) is too much. Runs longer than 25 feet (7.62 m) will require special
attention. The machine’s sensors may indicate that the machine is out of syrup, water, or CO
Consider the following solutions:

1. Increase the tubing size from 3/8 inch diameter to 1/2 inch diameter.

2. Install booster pumps in the supply lines. Use a vacuum regulating valve with syrup
booster pumps.

3. Increase primary CO

2 regulator pressure from bulk or tank CO2 to 105 - 120 PSIG (723.9

to 828.0 KPa). A secondary regulator will be necessary for pumps (syrup, water) to avoid
exceeding manufacturer’s recommended operating pressures.
