PLUMBING REQUIREMENTS
These brewers must be connected to a cold water system with 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 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 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.
A water filtration system must be installed for brewers used in hard water areas.
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 prevention 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.
NOTE - If a back flow preventer is required by code, a shock arrestor should be installed between back flow
preventer and dispenser. Installing the shock arrestor as close to the dispenser as possible will provide the best
results.
Plumbing Hook-Up
1. Flush the water line.
2. Securely attach ¼˝ water supply line to the el-
bow.
3. Secure cord and water supply line under the
retainer strap in any of the three locations as
needed. (Only 1 strap included)
4. Turn on the water supply.
Optional Drain Hook-Up
1. Remove drip tray and the chrome plug from the
base.
2. Drill out the auxiliary outlet of the drip tray with
a ½˝ drill bit.
3. Secure ½˝ hose to drip tray, routing it through
the opening in the base assembly.
4. Connect hose to drain line as needed.
5. Install drip tray.

INITIAL SET-UP
1. Install check valve. Refer to pictures on page 10.
2. Install clear brew chamber and empty brew cup. Lock
chamber in place.
3. Place an empty container that holds at least 20 ounces
under the brew chamber.
4. Connect the brewer to the power source.
5. Press the brew start switch. Water will flow into the brew
tank. Some excess water will flow into the container below
and the brew cup.
6. Wait approximately five minutes for the water in the tank to
heat to the proper temperature. Display will show "HEAT-
ING" until tank reaches it's operating temperature. Some
water will drip from the brew chamber during this time;
this is due to expansion and should not occur thereafter.
Any excess water in the brew chamber will be automatically purged at the end of the initial setup.
7. Water volumes and flow settings have been preset at the
factory. Refer to "Adjusting Brewing Parameters" section
of this manual should the volume need to be increased
or decreased.
8. The brewer is now ready for use in accordance with the
instructions for Coffee Brewing.
NOTE: If brewer has been drained/moved, perform "Reset to
first time" procedure on page 11.
