SAFETY
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 of electrical wiring.
Carbon Dioxide (CO2)
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. Should the valve become accidentally damaged or broken off, a CO2 cylinder can cause serious
personal injury.
General Precautions
This equipment, depending on the model, weighs up to 460 pounds. To avoid personal injury or damage, do
not attempt to lift the dispenser without help. The use of a mechanical lift is highly recommended. Because the
dispenser is top heavy be sure to maintain in a vertical, upright position when lifting and positioning.

INSTALLATION
General Location Requirements
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 page for specific
equipment weights.
Self Contained Refrigeration Models
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, or “doghouse”, installations that can re-circulate hot discharge air. Installations such
as this require supplemental ventilation to remove the hot discharge air. A fan with a thermal switch is a good
option. Airflow from the fan should be at least 850 CFM.
Although the dispenser will operate in temperatures up to 104°F, an ambient temperature is 75°F will provide
the optimal capacity. As the ambient temperature increases, the dispenser capacity decreases.
Because this equipment is designed for high capacity, a self contained air
cooled dispenser will reject a large amount of heat into the environment. It
is essential that the HVAC system be able to handle this heat load. The
average heat load over time that is rejected into the environment is shown
in the table. If this is a concern then a remote condensing model might be
considered instead.
Model Average Heat Load
772 5,000 Btu/Hr
773 6,250 Btu/Hr
774 6,250 Btu/Hr
Remote Condensing Models
Remote condensing models utilize a condenser assembly external to the building and are designed for
ambient temperatures from -10°F to 120°F. This configuration removes the heat and fan noise from the inside
environment and reduces the air conditioning load during the warm season. Because air flow is not a
high concern with this set up, this style dispenser is suitable for enclosed spaces and zero side clearance
installations (dispensers side by side).
Remote condensing models utilize a small air recirculation fan to assist in drying out any internal
condensation. This fan is located on the top of the dispenser and runs continuously. Do not stack objects on
top of the dispenser as this will block the airflow and damage the fan.
Dispenser Mounting
Countertop - Flush Mounting: When the dispenser is mounted on a counter top, one method of installation
is to set the dispenser directly on top of the counter top. If permanently mounting to the counter top, use the
mounting information located in the “Dispenser Mounting” section of this manual to drill holes in the counter
top. Once installed, with side panels removed, seal the dispenser to the countertop using bead of clear silicone
caulk around the base of the frame.
Countertop - Leg Mounting: Another counter top option is to use support legs that raise the dispenser four
inches off the counter top (Purchased separately. Contact customer service). This allows easy cleaning under
the dispenser and meets most state and local health department codes. The legs mount to the same frame
6

locations as the counter top mounting bolts.
Base Cart: A roll-around base cart (Purchased separately, contact customer service) can be used when a suit-
able counter top location is not available or it is desired that the BIB’s 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 bolts. Failure
to do so can result in serious injury should the dispenser fall off the cart. Once installed, seal the dispenser to
the cart using bead of clear silicone caulk around the base of the frame.
Connecting to Electrical Power
The dispenser is shipped with a 3 prong, locking type plug, either a 20A or 30A, depending on the model.
The mating wall receptacle must be a NEMA L-620-R or a NEMA L-630-R to 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.
Note the voltage drop on the LCD between idle and run modes. If it is greater than 10 volts then the power
supply is inadequate and needs to be addressed by a certified electrician.
Caution, Risk of Electric Shock. If the cord or plug becomes damaged, replace only with a cord and plug of
the same type.
Do not connect the dispenser to power at this time.
Connecting to Water Supply
Note: According to the National Sanitation Foundation (NSF), an ASSE 1022 approved back flow prevention
device must be installed on the water supply line before connecting to the dispenser. If needed, one can be
purchased from FBD under part number 12-2272-0001. The back flow device must have a line connected to
the vent that diverts any flow to a drain. Failure to do this can result in a flooded establishment!
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.
The water supply line should be 3/8” ID minimum. Flush several gallons of water through a newly fabricated
line to remove any debris. Connect to the fitting labeled “H20” on the rear of the dispenser using a 1/4” flair
nut and washer. Installing a shutoff valve near the connection will be helpful when removing the dispenser.
Do not turn on the water supply at this time.
Connecting to CO2 Supply
The CO2 supply 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 then the supply will most likely be at 110
to 120 PSIG. If this is the case, tee off the main line and install a wall mount secondary regulator set to 70
PSIG. Fabricate a 3/8” ID line from the secondary regulator (independent tank or wall mount) to the rear of
the dispenser and connect to the bulkhead fitting labeled “CO2” using a 1/4” flair fitting. This regulator should
only supply CO2 to 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 BIB’s and syrup pumps inside then install a tee in the supply CO2
line to feed the syrup pumps.
Do not turn on the CO2 supply at this time.

Connecting to Syrup Supply
Installations requiring tubing runs over 50 feet may encounter pressure fluctuation issues due to
excessive pressure drop and subsequently cause false sold out conditions. Use at least 1/2” ID tubing in these
situations. Also consider installing booster pumps on the supply lines. Increasing the regulated CO2 pressure
on the syrup pumps can also help maintain proper syrup pressure at the dispenser. Be sure not to exceed the
pressure rating of the syrup pump.
Fabricate 3/8” ID lines from the syrup pumps to the rear of the dispenser and connect to the proper syrup
bulkhead fittings using a 1/4” flair fitting (each barrel has a fitting that is labeled). Installing a shutoff valve near
the connection will be helpful when removing the dispenser.
Do not turn on the CO2 supply at this time.
