SAFETY PRECAUTIONS
We at FBD are concerned about your safety. Please carefully read the following precautions before working with
FBD352 units. 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 use of a
mechanical lift is recommended
••
The empty FBD352 unit weighs approximately 220 pounds (99.8 kg).
•
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 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 CO2 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 CO2 cylinder can cause serious personal injury.

1.2
ADDITIONAL REQUIREMENTS (TO BE PROVIDED BY THE CUSTOMER)
A. CO2 supply with a pressure of 70-72 psig (0.483 to 0.496 MPa). If a bulk CO2 supply is
used, the pressure should be set at 115 to 120 psig (0.793 to 0.827 MPa) and a secondary
regulator installed at the unit to reduce the pressure to 70-72 psig (0.483-0.496 MPa).
B. Syrup supply using Bag-in-Box or five (5) gallon syrup tank (figal).
C. Water supply with a minimum flowing pressure of 30 psig (0.207 MPa) and a maximum static
pressure of 70 psig (0.483 MPa).
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. 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.
3. INSTALLING THE UNIT
There are several ways to install the unit. Follow the appropriate directions for the method you are
using. Ensure that there is a minimum of twelve (12) inches (30.48 cm) open space ABOVE
and two (2) inches (5.08 cm) open space on at least one side and BEHIND the unit (see
Figure 1.1) for proper ventilation.
7
3.1
FLUSH MOUNTING
A. Flush mounting is when the unit is mounted on a counter top. Follow the following guidelines to
ensure a proper installation.
1. Be sure the counter will support the weight of the specific FBD unit being installed and the
full length of the unit (including the drip tray). If permanently mounting the unit to a counter
top, use the information in Section 12.1 to mark and drill the four (4) mounting holes in the
counter top.
2. Place unit on the counter using a lift (see Safety Precautions, page 2).
3. If permanently mounting the unit to a counter top, install four (4) 3/8-16 UNC bolts (not
included) through the underside of the counter and into the frame [through the four (4)
mounting holes drilled in the step just above].
4. 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
A. A roll around cart is used when a suitable counter top is not available and allows the unit to be
moved for cleaning. These can be purchased from the dealer.
1. Lock the wheels on the roll around cart.
2. Place the unit on the cart (see Safety Precautions, page 2).
3. 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.
4. CONNECTING TO ELECTRICAL POWER
4.1
230 VAC/50 Hz SERVICE
A. Use the following guidelines to connect electrical power to the machine for 230 VAC/50 Hz
service.
1. The machine requires single phase 230 VAC. If line voltage is below 200 VAC or above
254 VAC, a 10% buck and boost transformer must be used. Operation below 200 VAC or
above 254 VAC may damage the unit and cause inconsistent performance. This also voids
all warranties.
2. The 230 VAC/50 Hz unit must be installed on a “single branch” circuit (on a circuit by itself),
installed as follows:
a. The Unit must be protected by 10 Amp service and a 10 Amp fuse (or circuit breaker).
It is recommended that a 3 conductor, 10 Amp receptacle be used. Using a voltmeter,
check voltage across both “hot legs” (230 VAC) and between ground and each “hot leg”
(115 VAC) to ensure proper wiring and voltage.
b. If connected to a “delta” three phase electrical system, use the two low voltage legs
(check each leg to ground to ensure 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 L2
contactor in the electrical box.
3. This unit will not work properly if there is more than a 10 volt voltage drop in the power
supply line between the power source and the machine. A drop of more than 10 volts
indicates undersized wiring or excessively long runs.
4. 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
B. Do not connect the unit to power at this time.
8
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 ENSURE BLACK CARBON “FINES” ARE NOT FED
INTO THE BARRELS.
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 a backflow prevention assembly to the water inlet of the unit (see Figure 5.2). A
backflow prevention assembly is available from FBD under PN 12-2272-0001.
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” located at the rear of the unit (see
Figure 5.2).
F. Route the drain line to a drain location.
G. Do not turn water on at this time.

CO2 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, install a shutoff valve and a secondary supply regulator [to be set at
70-72 psig (0.483-0.496 MPa)] in the line. Ensure that the CO2 line 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 CO2 flow and cause performance problems.
A. Fabricate a 3/8 inch supply line for connecting the unit to a CO2 supply.
B. Connect the supply line to the CO2 bulkhead fitting labeled “CO2” 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.
9
C. Splice a barb “cross” into the CO2 supply line and run two (2) lines to the syrup pump CO2
inlets.
Or
If a Figal tank will be utilized, splice a barb “cross” into the CO2 supply line and run two (2) lines
to tank location and install CO2 tank couplers to end of lines.
D. Do not turn on the CO2 at this time.
5.3
SYRUP SUPPLY
A. 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.
B. BIB SUPPLY
1. Fabricate the appropriate number of 3/8 inch supply lines for connecting the unit to the syrup
pumps.
2. Connect the syrup lines to the bulkhead fittings as follows:
a. For the FBD352 Unit - Connect to bulkhead fittings labeled “SYRUP LEFT” and “SYRUP
RIGHT” located at the rear of the unit (see Figure 5.2).
3. Do not turn on the CO2 at this time.
NOTE
Installations requiring long runs of tubing [25 feet or more (7.62 meters or more)] 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 1/2 inch diameter.
b. Install booster pumps in the supply lines. Use a vacuum regulating valve with syrup
booster pumps.
c. Increase primary CO2 regulator pressure from bulk or tank CO2 to 115 - 120 psig (0.724
to 0.827 MPa). A secondary regulator will be necessary for syrup pumps to avoid
exceeding manufacturer’s recommended operating pressures. Set the secondary
regulator to 70-72 psig (0.483-0.496 MPa).
C. FIVE GALLON (FIGAL) TANK SUPPLY
1. Fabricate the appropriate number of 3/8 inch supply lines for connecting the unit to the syrup
tanks.
2. Connect the syrup lines to the bulkhead fittings as follows:
a. For the FBD352 Unit - Connect to bulkhead fittings labeled “SYRUP LEFT” and “SYRUP
RIGHT” located at the rear of the unit (see Figure 5.2).
3. 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.
a. 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 barrel and it will freeze up.
2. When replacing a figal, ensure that the syrup line to the dispenser is attached to the figal
before the CO2 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 barrel will then go out and product will refreeze.
4. Do not turn on the CO2 at this time.
5.4
CO2 VENTING/EXHAUST SYSTEM
NOTE
The exhausting of the CO2 gas to the outdoors must comply with local laws/statutes.
A. The FBD352 units have been fitted with a CO2 venting/exhaust system that will expell a CO2
gas leak from the CO2 regulator to an outside location. A pressure relief valve is fitted to the
secondary CO2 regulator (see Figure 5.4) and will exhaust CO2 gas if the pressure rises
10
above 63 psig (0.434 MPa). A cap has been placed over the Active Charge Regulator (see
Figure 5.5) and will direct vented CO2 gas to, and then out of, the exhaust tube.
1. Install a 1/4” tube to the CO2 exhaust bulkhead fitting on the back of the frame (see
Figure 5.3). This tube should be connected to an outdoor vent which complies with local
standards.

6. STARTING THE UNIT
IMPORTANT
THE FBD352 SETUP IS SIMILAR TO, BUT NOT EXACTLY THE SAME AS, OTHER FBD UNITS. YOU
MUST FOLLOW THESE PROCEDURES STEP-BY-STEP TO ENSURE THE PROPER SETUP IS
ACCOMPLISHED
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 barrel should be at the same temperature
as from the sample valve.
6.1
INITIAL POWER-UP
A. Plug unit in to the electrical power. The graphics display should illuminate. Check for the display
of information on the LCD keypad (this will read “COPYRIGHT” on bottom line of LCD display).
6.2
CO2 PURGE
A. Follow these steps to purge air from the barrels:
1. Turn on CO2 supply to the unit and adjust the secondary regulators to 60 psig
(0.414 MPa).
NOTE
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.
12
2. Close the inline shutoff valves or adjust the water and syrup flow controls all the way out
(counter-clockwise).
3. Scroll down to “SYRUP SOL” and press the “SELECT” key to fill the barrel with CO2.
4. After about five (5) seconds, pull the pressure relief valve on the faceplate until no more air
is heard escaping.
5. Repeat previous step two more times.
6. Press “Select” again to turn off.
B. Repeat the purge process for the other barrel.
6.3
BRIXING
A. With the unit plugged in, press the “STOP ALL” button on the display to ensure the unit is in the
OFF state.
CAUTION
CHECK ALL SUPPLY LINES TO ENSURE 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 CO2 couplers, to figal tanks. Check all syrup
supply connections at the rear of the machine for leaks
D. Open the CO2 tank valve and adjust the primary tank regulator to 70-72 psig (0.483 to
0.496 MPa). Check all CO2 line connections for leaks.
E. Adjust the CO2 secondary regulators (located inside the machine) to read 58-62 psig (0.400 to
0.427 MPa).
F. Close Syrup flow controls by backing the right adjustment screw all the way out, by turning
counter-clockwise (see Figure 6.1).
G. Turn off the CO2 with the CO2 shut off valve (see Figure 6.1).
H. Adjust the water flow control two and one quarter (2 1/4) turns clockwise.
I. Open the sample valve and check the water flow rate and set to provide a flow of 15 ounces
(0.444 liter) in 10 seconds using a graduated container. Do this for every solution module. Turn
the water flow control (left adjustment screw) clockwise to increase flow or counter-clock-wise to
decrease flow. Repeat process for the remaining barrel.
J. Pre-set Syrup flow by turning Syrup flow controls in two and one fourth (2 1/4) turns (turning
clockwise).
K. Place a container under the sample tube and turn the sample valve until a good water and syrup
mixture is obtained (see Figure 6.1). This sample should be discarded.
L. Place a sixteen (16) ounce (0.473 liter) cup under sample tube and open the sample valve until
9 - 12 ounces (0.266 - 0.355 liter) have been dispensed into the cup.
M. 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.
After making any brix adjustments, open the sample valve for a few seconds to flush and
then discard. Run a 9 - 12 ounces (0.266 - 0.355 liter) sample to check brix again.
N. Repeat steps H through M above for the other barrel.
6.4
FILLING THE BARREL
A. Open CO2 shut off valve.
B. Select “Barrel 1”, then the “FILL” button to begin filling the barrel with product. If the barrel
does not fill, gently pull the relief ring until filling begins and then release. As the barrel fills, the
pressure in the barrel will increase until it rises above the psig fill point. At this point, the barrel
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 barrel is 90% full (level with relief
valve), then press Fill button to turn OFF. Fill one (1) barrel at a time.
C. Repeat step B for the remaining barrel.
D. Select “Barrel 1” and then press the “FILL” button, press the “DEFROST” button and then the
“RUN” button to begin the freezing process. Select “Barrel 2” and repeat the process. The unit
will complete a minimum forty-five (45) second defrost cycle on each barrel and then begin the

OPERATING ELECTRONIC CONTROLS
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. Buttons (see Figure 7.1)
1. The first 4 buttons listed are process buttons and are double acting switches. 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.
RUN/OFF
The RUN/OFF button initiates the freeze process. After pressing this button, the
beater motors will run for five (5) seconds before the compressor starts. Run
also maintains the flow of product into the barrels when needed. You should
always press the DEFROST button first to baseline the unit.
The BEATER button activates the beaters inside the barrels. The beaters can
be activated to mix the slurry.
NOTE:
BEATER
The beaters start automatically when the RUN or DEFROST buttons are
pressed.
DEFROST
The DEFROST button allows the user to manually defrost the barrel. Because
the unit automatically defrosts during the day, it is not necessary to defrost
manually. However, this button provides the option to do so if desired. (See
Note below.)
FILL
The FILL button activates the solenoid valves that allow product to flow into
the barrels (providing the pressure in the barrel is low enough to allow a fill).
Each barrel should be filled to 90% of capacity (level with the pressure relief
vent valves) prior to start-up.

9. BASICS OF OPERATION
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 FBD352 UNITS
A. In order to produce a consistent, quality beverage with the FBD352 Frozen Beverage Dispensers,
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 CO2 regulator located behind the
access panel behind the drip tray.
B. The settings that control product quality and production rate are:
1.
2.
3.
4.
Beverage Syrup Content or Brix Level (Set on Syrup Flow Control)
Barrel “Expansion”
Regulated CO2 Injection Pressure
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. A brix 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. A high brix level (higher than
15.0) causes freeze down times to be longer and produces a more liquid drink. Water
flow rate must be set to provide a flow of 15 ounces (0.444 liter) in 10 seconds prior to
adjusting brix.
2. “Expansion”
a. The FBD352 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 CO2 Injection Pressure
The CO2 injection pressure is set by adjusting the secondary regulator, located behind
the access panel and behind the drip tray in the front of the machine. The CO2 regulator
should be set at 58-62 psig (0.400 to 0.428 MPa). The unit then automatically sets the barrel
pressure between 25 and 30 psig (0.172 and 0.207 MPa).
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 barrel freezes until it reaches the desired
frozen consistency; then the refrigeration system shuts off and the barrel 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
20
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 expansion is properly set. Also assure the barrels stay filled to the
proper levels with the proper amount of CO2. The optimum 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.)
c. The Thaw and Freeze settings may be raised or lowered to change the temperature of
the product. A default setting of 10 is set at the factory. To decrease the temperature,
decrease the numerical setting; to increase the temperature, increase the numerical
setting.
9.2
NO DEFROST TIME BLOCK
A. The unit has defrost blocks that will prevent the unit from defrosting during a specified three (3)
hour time block. These defrost blocks will affect both barrels and can be programmed under
either of the barrel menus.
B. The “1 No Def St” and “2 No Def St” represent the start time setting for each defrost block.
C. To program the defrost block, use the following steps:
1. Scroll down until the desired defrost menu is displayed and press the SELECT button
2. Press the up or down buttons until the desired start time is shown (this is in 24 hour time
format).
Example:
1
No Def St. = 3
No defrost from 3 to 6 AM
2
No Def St. = 13
No defrost from 1 to 4 PM
3. Press the select button to save the setting.
9.3
SETTING WAKE/SLEEP TIMES
WAKE/SLEEP Set Procedure
A. Use the UP and DOWN arrows to scroll to WAKE/SLEEP.
B. Press the SELECT Key and then press the SELECT Key again to get into WAKE.
C. The numbers on WAKE will flash and at this point, use the UP and DOWN keys to change the
hour.
D. Press the Select Key again to make the minutes flash. Use the UP and DOWN keys to adjust
the minutes.
E. Press the Select Key again when done.
F. Use the scroll UP and DOWN keys to move to the SLEEP time.
G. Press the Select Key again, and the repeat steps C to E (above) for the SLEEP times.
H. Press the STOP ALL button to exit the WAKE/SLEEP Menu.
NOTE:
The unit will Defrost before going to sleep and when it wakes up.
10. CRITICAL INFORMATION
The following information is critical to proper machine operation. Prior to troubleshooting problems with the
unit, review the following information.
10.1 BARRELS 90% FULL ON INITIAL SET UP
Before beginning a RUN-FREEZE cycle, the barrels should be filled approximately 90% full (up
to relief valve). If the barrels are above the 90% level, with Fill Off, open the dispensing valve
and allow a small amount of liquid to drain out. If the barrels 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
screen will display “Filling”. While venting, do NOT let the pressure drop more than three to four
(3-4) psi (0.021 to 0.028 MPa).
21
10.2 LINE VOLTAGE DROP
The FBD352 units require a separate electrical circuit . For specific power requirements see
Sections 4.1 and 4.2. The unit will not function properly if the line voltage drops more than 10 volts
between the power source and the machine.
10.3 LONG TUBING RUNS
A. Long runs of supply tubing can cause problems if the pressure drop (between the CO2 tank or
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 CO2.
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 CO2 regulator pressure from bulk or tank CO2 to 115 to 120 psig (0.724
to 0.827 MPa). An additional regulator will be necessary for pumps (syrup, water) to avoid
exceeding manufacturer’s recommended operating pressures.
10.4 DRINK TOO HARD AND COLD
A. If the drink is too hard and cold or the barrel is not full, adjust the “Expansion” to a higher level
setting. Use the recommended settings that follow to properly adjust the Expansion settings.
B. It will be necessary to dispense several drinks to allow the barrel to fill and rebalance. After
dispensing several drinks defrost the barrel and refreeze. If the drink is still too hard, repeat the
process taking the Expansion setting to the next higher value.
10.5 DRINK TOO LIQUID
A. If the drink is cold, but is still a liquid, adjust the Expansion to a lower level setting. Use the
recommended settings that follow to properly adjust the Expansion.
B. It will be necessary to dispense several drinks to allow the barrel to fill and rebalance. After
dispensing several drinks defrost the barrel and refreeze. If the drink is still too liquid, repeat the
process taking the Expansion to the next lower setting.
C. Drink temperature should be between 24°F and 28°F (-4.4°C to -2.2°C).
NOTE
Check regulated CO2 pressures in the unit to make sure they are adjusted properly before
adjusting expansion controls!
10.6 CHANGING THE DEFAULT EXPANSION SETTING
A. The Expansion setting is preset at the factory at a value of 3.
B. If the drink is not frozen enough, or if the drink is too hard and too cold and dispenses slowly,
after the machine has been running for 10 to 15 minutes, it may be necessary to adjust the
Expansion settings.
C. To change the machine’s Expansion settings, scroll down on the Menu to Expansion.
