120V MODELS
These brewers must be connected to a cold water system with a minimum 1.0 gpm flow rate, and operating
pressure between 20 and 90 psi (138 and 620 kPa) from a ½˝ 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 (620
kPa) to reduce it to 50 psi (345 kPa). The water inlet fitting is .75-11.5 NH (HOSE THREAD). For convenience
an elbow adaptor is provided to convert to a ¼˝ flare fitting. Bunn-O-Matic does not recommend the use of a
reverse-osmosis or deionized water supply to this equipment.
NOTE - Bunn-O-Matic recommends ¼˝ copper tubing for installations of less than 25 feet and
3
⁄8" for more than
25 feet from the ½˝ 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.
Plumbing Hook-Up
1. Flush the water line.
2. TB3: Securely attach the adaptor elbow assembly to the ¼˝ water supply line.
TB6: Securely attach the tube assembly (supplied in parts box) to the ¼˝ water supply line.
3. TB3: Securely attach adaptor elbow assembly to the the .75-11.5 NH (HOSE THREAD) fitting at the rear of
the brewer.
TB6: Securely attach the two elbow assemblies to the .75-11.5 NH (HOSE THREAD) fittings at the rear of
the brewer. Connect the tube assembly to the elbows.
4. Turn on the water supply.
NOTE: The Flow Control/Strainer assembly is internal, located inside the inlet solenoid.
LP & "A/B" MODELS
These brewers must be connected to a cold water system with operating pressure between 20 (138) and 90
psi (620 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 (620 kPa) to reduce it to 50 psi (345 kPa). The
water inlet fitting is
1
⁄4" flare.
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 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.
NOTE - If a backflow preventer is required by code, a shock arrestor should be installed between backflow pre-
venter and brewer. Installing the shock arrestor as close to brewer as possible will provide best results.
Plumbing Hook-Up
1. Remove the shipping cap from the bulkhead fitting on the rear of the brewer.
2. Flush the water line and securely attach it to the bulkhead fitting on the rear of the brewer.
3. Turn on the water supply.
NOTE: TheFlow Control/Strainer assembly is internal, located inside the back panel.
PLUMBING REQUIREMENTS
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.
