Bunn SRU Operating & Service Manual page 5

These brewers must be connected to a cold water system with operating pressure between 20 and 90 psi
(138 and 621 kPa) 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 (621 kPa) to reduce it to 50 psi (345
kPa). The water inlet fitting is 3/8" flare.
NOTE - Bunn-O-Matic recommends 3/8" copper tubing for installations from the 1/2" water supply line. 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.
Plumbing Hook-up

2. Flush the water line and securely attach it to the 3/8" male flare fitting on the inlet of the strainer.
3. Turn on the water supply.
4. Inspect the connection for leaks.
This equipment must be installed to comply with the International Plumbing Code of the International
Code Council and the Food Code Manual of the Food and Drug Administration (FDA). For models
