5.5 Connecting to Water Supply
5.6 Connecting to CO
2
Supply
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 CO
2
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, 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 “CO
2
” using a 1/4" flare fitting. This regulator should only
supply CO
2
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 BIBs and syrup pumps inside then install a tee in the supply CO
2
line to feed the syrup pumps.
Do not turn on the CO
2
supply 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.
