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 12" or larger supply line. Ashut-offvalve 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 is14" flare.

NOTE - Bunn-O-Maticrecommends14" copper tubing for installations of less than 25 feet and38" for more than 25 feet from the12" 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-Maticdoes 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 Basic Plumbing Code of the Building Officials and Code Administrators International, Inc. (BOCA)

and the Food Service Sanitation Manual of the Food and Drug Administration (FDA).

1.Flush the water line and securely attach it to the inlet fitting at the left rear of the brewer.

2.Turn on the water supply.

INITIAL SET-UP

OPERATING CONTROLS

P1626

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-energizesthe 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.

NOTE Hot water will be available at the faucet in a limited amount when the "ON/OFF" switch is in the "OFF" position because the tank will not refill.

BREW SWITCH

Momentarily pressing and releasing the switch starts a brew cycle when the "ON/OFF" indicator is glowing. NOTE The "ON/OFF" indicator must be glowing to initiate and complete a brew cycle.

ADDITIONAL WARMER SWITCHES

Pressing any additional warmer switch so that the indicator is glowing, supplies power to the associated warmer.

READY INDICATOR

This indicator glows when the preset temperature has been achieved. The word "NOT" above "READY" will glow in all other instances.

TEMPERATURE INDICATORS (Feature disabled from the factory – refer to page 8.)

The indicator glows to communicate the brew water temperature. Two indicators will glow when the temperature is between them.
