PLUMBING REQUIREMENTS These brewers must be connected to a cold water system with operating pressure between 20 and 90 psi (138 1 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 1 inlet fitting is ⁄4" flare. 1 3 NOTE - Bunn-O-Matic recommends ⁄4" copper tubing for installations of less than 25 feet and ⁄8"

OPERATING CONTROLS ON/OFF SWITCH Pressing the "ON/OFF" switch (indicator glowing) supplies power to the brew station warmer, enables the brew circuit, and energizes the tank refill circuit. Pressing the switch again (indicator not glowing) stops tank refilling and brewing and de-energizes the brew station warmer. Stopping a brew cycle after it has been started will not stop the flow of water into the decanter until the funnel is empty. P1626 NOTE – Hot water will be available at the faucet in a
