Plumbing
1. 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 1⁄4" or larger supply line. 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).
2. Shut off valve should be present between water supply and machine.
3. Flush the water line and securely attach it to the inlet fitting at the rear of the brewer.
4. Turn on the water supply.
NOTE: Bunn-O-Matic recommends 1⁄4" copper tubing for installations of less than 25 feet and 3⁄8" for
more than 25 feet from the 1⁄2" water supply line. A tight coil of copper tubing in the water line will
facilitate moving the brewer 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.
