Plumbing Requirements; Tank Drain - Bunn Infusion Series Installation & Operating Manual

These brewers must be connected to a cold water system with operating pressure between 20 and 90 psi
(0.138 and 0.620 mPa) from a 1/2˝ or larger supply line. A shut-off valve should be installed in the line before
the brewer. Install a regulator in the line when pressure is greater than 90 psi (0.620 mPa) to reduce it to 50
psi (0.345 mPa). The water inlet fitting is .75-11.5 NH (HOSE THREAD). For convenience an elbow adaptor is
provided to convert to a 3/8˝ flare fitting. Bunn-O-Matic does not recommend the use of a reverse-osmosis or
deionized water supply to this equipment. REQUIRED: 2.0 gpm (7.57 lpm) flow rate from water supply line.
NOTE - Bunn-O-Matic recommends 3⁄8" copper tubing for all installations from the 1⁄2" water supply line. A tight
coil of tubing in the water line will facilitate moving the brewer to clean the countertop. 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 pre-
vention 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.
