PLUMBING REQUIREMENTS
These brewers must be connected to a cold water system with operating pressure between 20 and 90 psi
1
(138 and 620 kPa) from a ⁄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. Bunn-O-Matic does not recommend the use of a reverse-osmosis or
deionized water supply to this equipment.
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 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.
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 Adminis-tration (FDA). For models installed
outside the U.S.A., comply with the applicable Plumbing /SanitationCode.
Plumbing Hook-Up
1. Flush the water line.
2. Securely attach the Strainer/Flow Control and tube assembly to the water supply line.
3. Securely attach tube assembly to the flare fitting at the rear of the brewer.
4. Turn on the water supply.

3. Connect the brewer to the power source.
4. Press and release the "ENABLE BREW ON/OFF" switch. (Indicator/Display must be lit!). Water will flow into
the tank and stop when the tank is filled to its capacity.
5. Wait approximately twenty minutes for the water in the tank to heat to the proper temperature. Display will
show "READY" (green light on Silver Series) when tank is at operating temperature. Some water will drip
from the funnel during this time; this is due to expansion and is normal part of setup.
6. Water volumes and flow settings have been preset at the factory. Refer to Adjustments Section of this manual
to set brew volumes should the volume need to be increased or decreased.
7. The brewer is now ready for use in accordance with the instructions for Coffee Brewing.

(A) ENABLE BREW ON/OFF SWITCH
Pressing the "ENABLE BREW ON/OFF" switch (indicator on) enables the brew circuit, and energizes the tank refill
circuit. Pressing the switch again (indicator off) stops tank refilling and brewing. Stopping a brew cycle after
it has been started will not stop the flow of water into the server until the funnel is empty.
NOTE 1: – Stopping a brew cycle by pressing the "ENABLE BREW ON/OFF" switch to the "OFF" position, will dis-
able the tank refill circuit. If the level is low enough, tank heating may be disabled as well. Simply pressing the
"ENABLE BREW ON/OFF" switch to the "ON" position will allow the tank to replenish. Allow a few minutes for the
tank to heat back up to it's ready temperature.
NOTE 2: – Hot water will be available at the faucet in a limited amount when the "ENABLE BREW ON/OFF" switch
is in the "OFF" position because the tank will not refill. Refer to NOTE 1 regarding low level.
