4.10 Connecting to Water Supply
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.
Connect water line adapter to the bulkhead fitting labeled “WATER” or “H
2
O” on the back of the dispenser. The water
supply line connected to the bulkhead fitting should be a minimum 3/8” ID or larger if required by local codes. 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.
Note:
According to the National Sanitation Foundation (NSF), an ASSE 1022 approved backflow 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 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.
4.11 Connecting to Gas Supply
The
gas 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, 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 dispenser and connect to the appropriate bulkhead fitting. This regulator should only supply gas to the frozen
beverage dispenser (and base cart if applicable). Installing a shutoff valve near the connection is recommended. For
dispensers with multiple gas connections, verify the correct gas is connected to the correct fitting. If the dispenser is on
a base cart with the BIBs and syrup pumps inside, then install a tee in the supply gas line to feed the syrup pumps.
Do not turn on the gas supply at this time.
4.12 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 or flavor fitting.
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, consider installing booster
pumps on the supply lines. Increasing the regulated gas pressure on the syrup pumps (without exceeding the syrup
pump’s pressure rating) can also help maintain proper supply pressure at the dispenser.
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 gas supply for the syrup pumps at this time.
