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.
