1. SAFETY
1.1 Electrical
This dispenser 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 dispenser. Only qualified electricians should
perform this task and the work performed should meet all applicable codes.
Always disconnect electrical power to the dispenser to prevent personal injury before attempting any internal
maintenance. Only qualified personnel should service internal components or electrical wiring.
1.2 Carbon Dioxide (CO2)
Strict attention must be observed in the prevention of CO2gas leaks in the entire CO2and frozen 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 consciousness and suffocation.
To avoid personal injury and/or property damage, always secure CO2cylinders in an upright position with a
safety chain. A CO2cylinder with a damaged or detached valve can cause serious personal injury.
1.3 General Precautions
This equipment, depending on the model, weighs up to 194 pounds (88 kilograms) and is top-heavy. To avoid
personal injury or equipment damage, do not attempt to lift the dispenser without help. The use of a mechan-
ical lift is highly recommended. When lifting and positioning the dispenser, it should always stay in a vertical
upright position.
Children should be supervised to ensure they do not play with the dispenser.
Prior to use, persons (including children) with reduced physical, sensory or mental capabilities or lack of
experience and knowledge should be supervised or instructed about the use of the dispenser by a person
responsible for their safety.
2. Unit in Storage
If a unit is going to be placed in storage for an extended period (more than 90 days), it is recommended that
all rubber components be replaced (o-rings, rear seal, expansion tank, etc.). Failure to replace rubber compo-
nents could cause leaks which may damange components.
DANGER
!
ASPHYXIATION HAZARD
When the dispenser is mounted onto a base cart, it must be secured to the cart with bolts. Use
caution when moving the cart. Avoid surfaces that are not level and smooth under the width
of the casters to prevent tipping.

5. INSTALLATION
5.1 General Location Requirements
Dispenser is intended for indoor use only and should not be installed in areas where a waterjet can be used.
A flat, level location is required for proper installation. When using a counter, ensure it will support the weight
of the dispenser plus the weight of any equipment placed near it. See the specifications section for equipment
weights.
Note: Maximum installation angle for surface placement should not exceed 8º for proper operation of
dispenser.
Adequate space above and behind the dispenser is required to allow:
1. Removal of side panels, if service is necessary.
2. Air circulation around vents on sides, back, and top of dispenser.
A well-ventilated room is required with a temperature of 50°F to 90°F (10°C to 32°C). The environment, howev-
er, should be stable and not subject to abrupt changes in temperature. The dispenser should not be exposed
to direct sunlight or chemicals.
5.2 Self-Contained Refrigeration Models
4.2 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 dispenser.
D. Inspectdispenserforconcealeddamage.Ifevident,immediatelynotifydeliveringcarrierandlea
claim against same.
E. Lift dispenser up by the frame cross bracing and remove lower portion of carton.
F. If dispenser is received with a shipping board attached to the bottom, remove shipping board from
bottom of dispenser by accessing and removing the bolts located on the under side of the shipping
board.
4. RECEIVING AND UNPACKING DISPENSER
4.1 Receiving
Each dispenser is tested and thoroughly inspected before shipment. At the time of shipment, the carrier
accepts the dispenser and any claim for damages must be made with the carrier. Upon receiving the dispens-
er from the delivering carrier, carefully inspect carton for visible indication of damage. If damage is present,
have carrier note same on bill of lading and file a claim with the carrier.
Adequate clearance around the dispenser is required for proper air flow. Failure to provide proper clearance
will reduce capacity and can eventually damage the refrigeration system. See the specifications page for
clearance requirements. Be careful of enclosed installations that can recirculate hot discharge air. Such
installations require supplemental ventilation to remove the hot discharge air. A fan with a thermal switch is
a good option.
Although the dispenser can operate in temperatures up to 104°F (40°C), an ambient temperature of 75°F
(24°C) provides the optimal capacity. As the ambient temperature increases, the dispenser capacity decreas-
es. A self-contained, air-cooled dispenser can release a large amount of heat into the environment; therefore,it
is essential that the HVAC system be able to handle this heat load.

6
5.3 Dispenser Mounting
5.4 Connecting to Electrical Power
The dispenser is shipped with a 10 A plug. The mating wall receptacle must match the amperage rating of
the dispenser. If the plug on the dispenser is replaced with an alternate, it must have the same amperage
rating and provide a grounding prong. The dispenser must be connected to a dedicated circuit with the proper
amperage fuse rating.
The dispenser requires single phase 230 VAC. If the line voltage is below 208 VAC or above 248 VAC, a 10%
buck and boost transformer must be used. Operation below 208 VAC or above 248 VAC may damage the
dispenser and cause inconsistent performance. Operation outside the recommended voltage range also voids
all warranties.
Remove the plug from the power cord and feed the cord through the strain relief located at the back of the
dispenser. 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.
Note: The voltage drop on the LCD between idle and run modes must not exceed 10 volts between the power
source and the machine. If it is greater than 10 volts then the power supply is inadequate and needs to be
addressed by a certified electrician.
Countertop - Flush Mounting: One method of installation is to set the dispenser directly on a countertop.
If permanently mounting to the countertop, use the mounting information located in the “Diagrams and
Schematics” section of this manual to drill holes in the countertop. Once installed, with side panels removed,
seal the dispenser to the countertop using a bead of clear silicone caulk around the base of the frame.
Countertop - Leg Mounting: Another countertop option is to use support legs that raise the dispenser four inch-
es off the countertop (purchased separately). The legs mount to the same frame locations as the countertop
mounting bolts. This allows easy cleaning under the dispenser and meets most local health department codes.
Base Cart: A roll-around base cart (purchased separately) can be used when a suitable countertop location
is not available or it is desired that the BIBs and syrup pumps be located with the dispenser. If a base cart
is used, the dispenser must be secured to the cart using 3/8”-16 UNC or M8 bolts. Add nuts to fasten bolts.
Failure to do so can result in serious injury should the dispenser fall off the cart. Once installed, seal the dis-
penser to the cart using a bead of clear silicone caulk around the base of the frame.
Risk of Electric Shock: If the cord or plug becomes damaged, replace only with a cord and plug of
the same type provided by the manufacturer or service agency in order to avoid potential hazard.
CAUTION
Do not connect the dispenser to power at this time.

7
5.5 Connecting to Water Supply
5.6 Connecting to CO2Supply
Water pipe connections and fixtures directly connected to a potable water supply shall be sized, installed, and
maintained in accordance with local codes.
Connect water line adapter to the bulkhead fitting labeled “WATER” on the back of the dispenser (Figure 5.1).
The water supply line should be 3/8” ID minimum or whichever size local codes require. Before installing, flush
several gallons of water through a newly fabricated line to remove any debris. Installing a shutoff valve near
the connection will be helpful when removing the dispenser.
Do not turn on the water supply at this time.
The CO2supply may come from either an independent tank with a primary/secondary regulator or a bulk tank
that supplies other equipment. If the supply is from a bulk tank, supply pressure must not exceed 120 psig
(827 kPag). Tee off the main line and install a wall-mounted secondary regulator set to 70 psig (483 kPag).
Fabricate a 3/8” ID line from the secondary regulator (independent tank or wall mount) to the rear of the dis-
penser and connect to the bulkhead fitting labeled “CO2” using a 1/4" flare fitting. This regulator should only
supply CO2to the frozen beverage dispenser. Installing a shutoff valve near the connection will be helpful
when removing the dispenser.
If the dispenser is on a base cart with the BIBs and syrup pumps inside then install a tee in the supply CO2
line to feed the syrup pumps.
Do not turn on the CO2supply at this time.
Note: If local codes require the installation of a backflow prevention device to be installed on the water supply
line before connecting to the dispenser, one can be purchased from FBD under part number 12-2272-0001.
The backflow device must have a line connected to the vent that diverts any flow to a drain. Failure to divert
flow can result in water overflow.

5.7 Connecting to Syrup Supply
For installations requiring syrup lines less than 50 ft (15 m) in length, use tubing with a minimum ID of 3/8”. Run
the syrup lines from the pumps to the rear of the dispenser and connect to the proper syrup fitting (Figure 5.1).
For installations requiring syrup lines over 50 ft (15 m) in length, use tubing with a minimum ID of 1/2”. Using
tubing of any smaller diameter will lead to pressure fluctuations and false sold-out errors. Furthermore, con-
sider installing booster pumps on the supply lines. Increasing the regulated CO2pressure on the syrup pumps
can also help maintain proper supply pressure at the dispenser; however, be sure not to exceed the pressure
rating of the syrup pumps.
In all situations, it is recommended to install a shutoff valve near the connection to the back of the dispenser
to assist with servicing or removing the dispenser.
Do not turn on the CO2supply for the syrup pumps at this time.
5.8 Long Tubing Runs
Long runs of supply tubing can cause problems if the pressure drop (between the CO2tank or syrup source
and the dispenser) 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 CO2regulator pressure from bulk or tank CO2to 105 to 120 psig (724 to
827 kPag). An additional regulator may be necessary for pumps (syrup or water) to avoid exceeding
manufacturer’s recommended operating pressures.

6. STARTING UP THE DISPENSER
6.1 Leak Check
1Remove the drip tray below the dispenser and remove the front metal panel covered with the drip
tray. The two solution modules inside the dispenser should be visible once metal panel is removed.
2Connect the BIB connectors to the syrup BIB’s.
3Open the water supply shutoff valve (Section 5.5). On one of the solution modules, close the CO2
shutoff valve (Figure 6.1). Open the sample valve until water flows out of the sample port, then
close the sample valve.
4 Open the CO2,water,andsyrupshuto󰀨valves.
Note: The pump and syrup pump will operate automatically and feed the dispenser until the inter-
nal pressure is balanced. This feed is normal and does not last long.
5Check all connections thoroughly for leaks.
6Open the sample valve (Figure 6.1) and collect the water/syrup being dispensed into a cup.
Continue to prime until syrup flow has been established and all air has been removed from the
lines. Discard the samples.
7Repeat for the other module.

6.2 Initial Power Up
Plug the dispenser into the power supply and verify the dispenser turns on by looking at the display behind
the merchandiser (see Section 5.4). The LCD display should illuminate and should read "COPYRIGHT
94-2019 FBD" on the bottom line. See Section 10 for additional information on keypad buttons and how to
navigate through menus.
Note: If the screen does not power on, please power off the dispenser immediately and contact the dealer.

6.3 CO2 Purge
Follow these steps to purge air from the barrels:
1. Turn off the water and syrup supply shutoff valves to the dispenser (Section 5.5).
2. Open the CO2supply device and adjust the regulator on one of the solution modules to 60 psig (414
kPag).
Note: This regulator is a non-venting regulator. It will be easier to adjust by increasing pressure. If the reg-
ulator setting is reduced to lower pressure, the pressure must be vented by opening the solution module
solenoid manually using the Filling Sol 1 or 2 function in the Manual ON/OFF menu and pressing SELECT
before the set pressure is displayed on the pressure gauge. If the pressure reading does not reduce it will
be necessary to pull open the relief valve on the faceplate (Figure 6.3) to vent the pressure in the barrel.
3. Open the solution module solenoid manually using the Filling Sol 1 or 2 function in the Manual ON/
OFF menu and pressing SELECT to fill the barrel with CO2.
4. After about five (5) seconds, pull the pressure relief valve on the faceplate until no more gas is heard
escaping.
5. Repeat previous step two more times.
6. Close the solution module solenoid manually using the Filling Sol 1 or 2 function in the Manual ON/
OFF menu by pressing SELECT again.
Repeat process for other barrel.
6.4 Brixing
To ensure the dispenser produces a quality beverage and continues to operate properly, it is important to check
and adjust the brix of the beverage before use. All dispensers have been set correctly before leaving the fac-
tory,butthedi󰀨erencesinsyruprequiretheusertocheckoradjustbrixsettings.Usethefollowingprocedure
to set the brix for each barrel:
1. Press the STOP ALL button on the display to ensure the dispenser is in the OFF state.
Note: Check all supply lines to ensure that they are connected to the correct fittings (Section 5). If
lines are not connected properly, components will be damaged.
2. Open the water supply valve and check all water line connections for leaks.
3. Check all syrup supply connections at the rear of the machine for leaks.
4. Open the CO2tank valve and adjust the primary tank regulator to 70 to 72 psig (483 to 496 kPag).
Check all CO2line connections for leaks.
5. Adjust the CO2solution module regulators (located inside the machine) to read 58 to 62 psig (400 to
427 kPag) as described in Section 6.3.
6. Close syrup flow controls by backing the right adjustment screw on the solution module all the way
out turning it counterclockwise (see Figure 6.2).
7. Turn off the CO2shutoff valve (see Figure 6.2).
8. Adjust the water flow control two and one quarter (2 1/4) turns clockwise from the full counterclock-
wise stop.

11
9.
Open the sample valve. Adjust the water flow rate to 1.5 oz/sec (44.4 ml/sec) by dispensing water
from the solution module through the sample port for 10 seconds into a measuring cup. The
amount measured should be 15 oz (444 ml). Turn the flow control clockwise to increase the flow
and counterclockwise to reduce the flow.
10. Open the syrup supply valve and check syrup line connections for leaks. Preset syrup flow by
turning flow controls two and one fourth (2 1/4) turns clockwise on solution module.
11. Place a container under the sample port (see Figure 6.2) and open the sample valve until a good
water and syrup mixture is obtained. This sample should be discarded.
12. Dispense a 9-12 oz sample and measure the brix with a refractometer. Be sure to thoroughly mix
the sample first by pouring back and fourth in two cups.
13. Turn the syrup flow control counterclockwise to decrease the brix. Turn the syrup flow control
clockwise to increase the brix.
14. Dispense and discard several samples after adjusting the brix.
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. The brix reading is affected by temperature;
samples taken from the barrel should be at the same temperature as from the sample valve.
15. Repeat steps 8 through 14 for other barrel.
The target brix for most sugar flavors is between 13.5 and 15. The target brix for most "light" flavors will be
lower, usually between 9 and 10. Check the specifications for the flavors if unsure of the target brix.
Note: Light or diet products have a low brix and can cause problems with the dispenser if not properly set up.
Although these products have ingredients to replace the antifreezing properties of sugar, they can still create
excessive ice if not carefully brixed according to their specifications. Low brix issues will be associated with
events such as audible ice scraping during freeze and low beater problems.

6.5 Filling Barrel
The barrel, or freeze chamber, must be purged of air before filling with product. Failure to displace the air with
CO2will result in poor drink quality.
Figure 6.3 DDV Faceplate
Relief
Valve
1. Open the CO2shutoff valve on the solution module for barrel 1.
2.
Select BARREL 1 on the keypad, then the FILL button to begin filling the barrel with product. If
the barrel does not fill, gently pull the relief valve ring (see Figure 6.3) 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
(set by dispenser software). At this point, the barrel will stop filling and the LCD will read “Fill Hold”.
It will then be necessary to pull the relief valve to relieve the pressure and allow filling to continue.
Slowly pull the relief valve 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.
3. Repeat step 2 for BARREL 2.
4.
Select BARREL 1, then press FILL, press the DEFROST and then the RUN buttons to begin the
freezing process. Select BARREL 2 and repeat the process. The dispenser will complete a mini-
mum forty-five (45) second defrost cycle on each barrel and then begin the freeze process.
5.
After an initial freeze down, 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 CO2
is properly and adequately absorbed, drinks could be too “wet” or too “heavy”. If adjustments are
necessary, refer to Section 7.
6. Check CO2, water, and syrup lines again for leaks.

7. DISPENSER OPERATION
Thereareafewcriticalsettingsthata󰀨ectdrinkquality.Thesesettingsarepresetwhenyoureceivethedis-
penser from the factory. However, due to variations that occur (e.g., in operating environments, syrups, dis-
penserdi󰀨erences,etc.),itmaybenecessarytomakeminoradjustmentstothesecriticalsettings.Adjustments
are easily made using the keypad located behind the merchandiser door at the front of the machine*, or by
adjusting the CO2regulator located behind the access panel behind the drip tray.
There are several settings that control product quality:
A. Brix (syrup content of beverage)
B. Expansion
C. Regulated CO2injection pressure
D. Freeze and thaw settings
If the drink quality is not as desired, even after the stabilization period, check the critical settings (listed above)
and make the necessary adjustments. The sections that follow provide additional information on these and
other settings.
Note: On an initial freeze down, products must be given adequate time to stabilize. Adjustments made too
quickly may negatively affect drink quality.
7.1 Brix
To ensure the dispenser produces a quality drink, the syrup content of the drink or brix level must be maintained
between 13.5 and 15. A brix level lower than 13.5 may cause operational problems, 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owratemustbesettoprovideaowof15
ounces in 10 seconds (444ml/10 seconds) prior to adjusting brix (see Section 6.4).
7.2 Expansion
The dispenser utilizes a patented liquid level control system to hold a constant liquid level. A constant liquid
level assures a quality frozen product. If a “wetter” 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. The default
setting is 3 and should produce a quality drink.
Note: Before changing the Expansion settings, check the regulated CO2pressures for the dispenser to make
sure they are adjusted properly before adjusting expansion controls.
A drink with not enough CO2 will be heavy and may look dark in the barrel. A drink with too much CO2will be
very light and may even collapse in the cup.
* See Section 10 for additional information on keypad buttons and how to navigate through menus.
1. In the Settings menu, use the UP and DOWN keys to scroll to
the Expansion.
2. Use the SELECT key to make the number blink.
3. Use the arrow key to change to the desired Expansion.
4. Use the SELECT key to set the value.

14
7.3 Regulated CO2Injection Pressure
The CO2injection pressure is set by adjusting the CO2regulators on the solution module, located behind the
access panel below the keypad in the front of the machine. The CO2regulators should be set at 58 to 62 psig
(400 to 427 kPag). The dispenser then automatically sets the barrel pressure between 25 and 30 psig (172 and
207 kPag).
7.4 Thaw and Freeze Settings
The thaw and freeze settings signal the refrigeration system when to start and stop freezing. The liquid in the
barrelfreezesuntilitreachesthedesiredfrozenconsistency;then,therefrigerationsystemshutso󰀨andthe
barrelbeginstothaw.Theliquidcontinuestothawuntilitreachesaconsistencyspeciedbythethawvalue.
The thaw value is the point at which the refrigeration system turns back on and refreezes the product. This as-
sures the product is maintained in a good, acceptable, frozen drink range.
Priortochanginganythaworfreezesettings,makesurethebrixandwaterowratearecorrectandtheliquid
levelcontrolsettingsareproperly set.Also assurethe barrelsstay lledto theproperlevels withthe prop-

7.7 Drink Quality
Manyfactorscana󰀨ectthequalityofafrozenbeveragesuchastimesincelastdefrost,brandand/ortypeof
syrup used, and the local water quality. Drink quality settings are designed to be adjustable to compensate for
naturaldi󰀨erencesindrinksandcanbeadjustedtodrinkqualityofpersonalpreference.
Please note that a barrel that has been idle for hours, such as overnight, will produce a wetter heavier drink.
It is best to dispense a drink or two to recondition the barrel. This fact should be considered before making a
judgment on the drink quality.
7.8 Drink Too "Firm" or Cold
Adrinkthatisover-frozenwilltendtobeverycold,below22°F(-5.5°C),andcanbeconsideredhardanddi󰀩cult
to suck through a straw. It can also be lighter in weight than a properly frozen drink and tends to collapse in the
cup after being dispensed. To correct this, adjust the Expansion to a higher level setting. See Section 7.2 to
properly adjust the Expansion settings.
Itwillbenecessarytodispenseseveraldrinkstoallowthebarreltollandrecondition.Afterdispensingseveral
drinks, defrost the barrel and refreeze. It will take several compressor cycles before the product in the barrel
hasreconditionedtothenewsetting.Ifthedrinkisstilltoorm,repeattheprocesstakingtheExpansionsetting
to the next higher value.
Note: Before changing the Expansion settings, check the regulated CO2 pressures for the dispenser to make
sure they are adjusted properly before adjusting expansion controls.
7.9 Drink Too Liquid
If the drink is cold, but is still a liquid, adjust the Expansion to a lower level setting. See Section 7.2 to properly
adjust the Expansion settings.
Itwillbenecessarytodispenseseveraldrinkstoallowthebarreltollandrecondition.Afterdispensingseveral
drinks, defrost the barrel and refreeze. It will take several compressor cycles before the product in the barrel
has reconditioned to the new setting. If the drink is still too liquid, repeat the process taking the Expansion to the
next lower setting. Drink temperature should be between 24°F and 28°F (-4.4°C to -2.2°C). If the temperature
is outside this range then check or adjust the Thaw and Freeze settings (see Section 7.4).
Note: Before changing the Expansion settings, check the regulated CO2 pressures for the dispenser to make
sure they are adjusted properly before adjusting expansion controls.
1. In the Settings menu, use the UP and DOWN arrows to scroll to WAKE TIME.
2. PresstheSELECTkeyandhournumberswillash.
3. Use the UP and DOWN keys to change the hour.
4. PresstheSELECTkeyagaintomaketheminutesash.UsetheUPandDOWN
keys to adjust the minutes.
5. Press the SELECT key again when done.
6. Use the UP and DOWN keys to scroll to SLEEP TIME.
7. Press the SELECT key again and repeat steps 3 through 5 (above) for the
SLEEP times.
Note: The dispenser will defrost before going to sleep and when it wakes up.

7.10 Defrosting
To maintain optimal product quality a frozen drink must be periodically defrosted because ice crystals grow
in size over time and degraded the consistency and texture of the drink. The best drink quality is always right
after defrost and refreeze. Naturally, it is ideal for the dispenser to be ready to serve drinks at all times so a
balance between defrost and up time must be maintained. During times of high volume dispensing, a barrel can
go longer without defrosting while low volume periods should defrost every three to four hours. This machine
provides automatic defrosting every three hours if no drinks are dispensed. Dispensing drinks increases the
time between defrost cycles. If additional defrosting is desired, it can be done manually ( see Section 10.6). No
defrost time blocks can also be set (see Section 7.5).
7.11 Barrels 90% Full on Initial Set-Up
BeforebeginningaRUN-FREEZEcycle,thebarrelsshouldbelledapproximately90%full(uptoreliefvalve
level).Ifthebarrelsareabovethe90%level,withFillO󰀨,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 relief valve
onthefaceplatetoventgasandallowbarreltoll(thescreenwilldisplay“Filling").Whileventing,DONOTlet
the pressure drop more than three to four (3-4) psig.
7.12 Freeze
To freeze the product down, select the barrel by pressing BARREL 1 or BARREL 2 and then press the RUN
button. If the product is liquid, it will take 13 to 15 minutes per barrel (depending on temperature of product) to
complete the initial freeze cycle. Dispense two drinks to condition the barrel.
7.13 O󰀨
Therearetwooptionsforturningo󰀨thedispenser.Therstistoturno󰀨onebarrelatatime.Toturno󰀨,select
thebarrelbypressingBARREL1orBARREL2andthenpresstheOFFbutton.Thesecondoptionistoturno󰀨
both barrels at the same time. To do this, press the red STOP ALL button.

8. CLEANING AND SANITIZING THE UNIT
8.1 General Information
The dispensers are shipped from the factory cleaned and sanitized. After installation of the dispenser, the op-
erator must provide continuous maintenance as described in this manual and/or local codes to ensure proper
operation and sanitation requirements are met.
Cleaning and sanitizing should be carried out 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.
A few precautions while cleaning:
• Water lines are NOT to be disconnected during the cleaning and sanitizing process. This is to avoid con-
tamination.
• DO NOT use strong bleaches or detergents when cleaning the exterior of the equipment. They will discolor
and possibly corrode various materials.
• DO NOT use metal scrapers, sharp objects, steel wool, scouring pads, abrasives, solvents, etc., on the
dispenserastheycandamagethenishonvariousmaterials.
• DO NOT use waterjet to clean dispenser.
8.2 Daily Cleaning
A mild soap solution such as hand dishwashing detergent diluted with water at 90°F to 100°F (32°C to 38°C)
should be used to clean the exterior of the equipment. Remove all product residues from the surfaces of the
dispenser. Rinse thoroughly using clean water also at 90°F to 100°F (32°C to 38°C) to remove the remaining
soap. Remove the drip tray (if not connected to drain plumbing) and cup rest and clean in a sink using a mild
soap solution.
8.3 Sanitizing
The dispenser should be sanitized yearly. Prepare a chlorine solution containing 100 PPM of available chlorine
with clean water at 90°F to 100°F (32°C to 38°C). Commercial beverage equipment sanitizing and cleaning
solutions such as Kay-5 or Stera Sheen are preferred because they also contain surfactants to assist in clean-
ing. If using a commercial sanitizer/cleaner such as this, then prepare according to their directions.
The following procedure must be followed for sanitizing the dispenser.
1 Press the STOP ALL button, followed by the DEFROST button, for both barrels.
2Turno󰀨waterandsyrupattheinletofthedispenseroratthesource.
3 After defrost is complete, activate the solution solenoids on each barrel.
4 Place a container under the dispensing valve and empty the barrels. Activate the beaters to facili-
tate removal of product.
5Turno󰀨thesolutionsolenoidsandbeatersafterthebarrelsareempty.
6Prepareve(5)gallonsofsanitizingsolutionfollowingmanufacturer’sdirections.Thewater
temperature should be 110°F to 115°F (44°C to 46°C). Stir the solution until sanitizing agent has
completely dissolved.

18
7Take an empty BIB and cut off the connector. Attach the BIB connector to the connector
on the syrup line to serve as a BIB adapter. This will open up the syrup line connector and
allow for cleaning solution to be pumped into the dispenser.
8Open the sample valve unitl water is purged from the system.
9Place a container under the sample port and open the sample valve to purge syrup and
water from lines. When the tubing is clear of syrup, lower sanitizing BIB adapters into san-
itizing solution. Continue purging lines until any syrup in the line clears.
10 Activate the solution solenoids for each barrel using the SELECT key.
11 Fill each barrel approximately 2/3 full with sanitizing solution/water mixture then deactivate
the syrup solenoids.
12 Remove the BIB connectors from the cleaning solution.
13 Activate the solution solenoids to evacuate the solution from the barrels. Once the barrels
are evacuated, deactivate the solution solenoids and purge pressure from cylinders by
pulling faceplate relief valve.
14 Place the BIB connectors in the cleaning solution and activate the solution solenoid and
allow the barrels to fill 1/2 full of sanitizing solution. Deactivate the solution solenoids and
turn on beaters. Let solution agitate for three (3) minutes.
15 Remove the BIB connectors from the cleaning solution.
16 Activate the solution solenoids and evacuate the sanitizing solution from the barrels. Turn
off beaters, deactivate the solution solenoids and purge pressure from barrels.
17 Remove sanitizing adapters from the BIB lines and reconnect the lines to the syrup supplies.
18 Turn on water at source.
19 Partially refill the barrels (1/3 full) with syrup and water by activating the solution solenoids.
Turn off the solenoids. Run the beaters for a few seconds.
20 Drain the product by opening the dispense valve.
21 Partially refill the barrels again and test the product for off-taste. Repeat the drain/fill pro-
cess until no off-taste exists.
22 When there is no more off-taste, fill the dispenser following the procedure outlined in
Sections 6.3 through 6.5.

19
The air filter must be cleaned monthly to ensure proper operation of the dispenser. A dirty air filter will reduce
the refrigeration capacity and can potentially damage the compressor. To remove the filter, start by removing
the left and right side panels. The filter will be located under the condenser on the back top section of the
dispenser (see Figure 9.1). Remove the filter by bending the corners in and pulling the filter down and then
out through one of the sides of the dispenser. Clean the filter with a mild dishwashing soap and water solution
and dry thoroughly before reinstalling. Make sure to not use water that is too hot or it may damage the filter.
A degreaser may be required if the filter is greasy. To install the filter, slide into filter location through one of
the sides of the dispenser being careful not to pull on any of the harnesses. Once filter has been placed over
back top section of the dispenser, push the filter up so that it sits on the frame edges.
NOTE: If the dispenser is located in a particularly dusty area or with airborne grease such as the cooking area
of a fast food restaurant, then the filter should be cleaned every two weeks.
