SITE REQUIREMENTS

Plumbing

1. Quick connect assembly with adapter (supplied).

2. 3/8˝ NPT fi tting on water fi lter.

3. 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).

4. Shut off valve should be present between water
supply and machine.

5. Vented drain available within 3.3 feet (1 meter) of

6. Flush the water line and securely attach it to the
inlet fi tting at the rear of the brewer.

7. Turn on the water supply.
NOTE - Bunn-O-Matic recommends 1⁄4" copper tub-
ing 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 fl ow.
