to clean the counter top. Bunn-O-Matic does not recommend the use of a saddle valve to install the brewer. The
size and shape of the hole made in the supply line by this type of device may restrict water flow.
As directed in the International Plumbing Code of the International Code Council and the Food Code
Manual of the Food and Drug Administration (FDA), this equipment must be installed with adequate
backflow prevention to comply with federal, state and local codes. For models installed outside the
U.S.A., you must comply with the applicable Plumbing /Sanitation Code for your area.

PLUMBING HOOK-UP

NOTE - If a backflow preventer is required by code, a shock arrestor should be installed between backflow preventer
and dispenser. Installing the shock arrestor as close to dispenser as possible will provide best results.
