4.7 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 “H2O” 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.
