Refer to B-Series Programming Chart on page 5.

Pour-Over Mode

Left display controls this.

•The display will read “P-O” (pour-over).

•Press “BREW” button to proceed to the next setting.

•Press up or down arrow to change to “YES” or “NO”. Plumbed-in units must be set to “NO”.

•Press “BREW” button to accept and exit menu.

SETTING BREW VOLUME:

•Remove brew basket & spray head.

•Make sure “READY” light is on.

•Place empty server under exit nozzle to capture water.

•Press “BREW” button to fill water lines.

•Press “BREW” button again after approximately 10 seconds to stop water flow.

•Empty server then place under exit nozzle.

•Press-and-hold “BREW” button for 5 seconds until display reads “Pro”, then release.

•Press-and-release “BREW” button to initiate brew.

•The brew valve opens and the time begins to count up on display.

•Water will flow into decanter.

•When water level reaches desired amount, press-and-release “BREW” button again.

•Time value will flash in the display.

•Press-and-release “BREW” button within 10 seconds to set time.

•Reinstall spray head and brew basket.

•Repeat process for each brew head.

BREWING PROCEDURE:

•Place a new paper filter in the brew basket.

•Put desired amount of ground coffee in brew basket. (3.5 oz (100 grams) maximum)

•Place decanter or airpot under brew basket.

•Be sure lower warmer is on. (if available)

•Press “BREW” button to start brewing.

The “READY” light will flash for the entire brew cycle.

Water will dispense for the set time of brew, and light will flash after water is dispensed to denote “drip time”.

(ex.. Time set for 2:30, water is dispensed for 2:30, and light continues to flash for another 1:15 for total brew cycle of 3:45.) Do not remove the brew basket while the “READY” light is blinking.

A stop function is added to the “BREW” switch. Pressing the “BREW” switch during a brew cycle will stop the brew. Coffee will need to be emptied from brew basket and brew procedure will need to be started again.

After a brew cycle, the tank must reheat and the “READY” light must be lit before starting the next cycle. Reheat (recovery) time is dependent on voltage applied and inlet water temperature.

Approximate reheat times for a 64 oz decanter are as follows:

120 Volt supply: 3-4 minutes; 120/208 Volt supply: 30-90 seconds; 120/240 Volt supply: 0 – 30 seconds

PULSE BREWING MODE:

•When mode is “ON” (number of pulses, pulse on, and pulse off time), and a brew cycle is initiated, water is dispensed for the ON time then stops for the OFF time to define one pulse. This repeats for number of pulses programmed. After pulsing is finished, the water continues to dispense for the remaining set time. During the pulse-off time, the water infuses the coffee and the bed rises to allow for better extraction.

•When mode is “OFF” and a brew cycle is initiated, water is dispensed continually for the entire set time without any delay.

ENERGY SAVINGS MODE (WARMER SHUT-OFF):

(ONLY FOR MODELS WITH WARMERS)

When set time has elapsed after a brew cycle, the lights above the warmer switches will flash and the warmers will automatically turn off. To stop lights from flashing, press one of the warmer switches. To turn warmers back on, press corresponding warmer switch. The timer will reset when a new brew cycle is initiated.

Refer to Adjustments section to adjust time values or simply disable mode. Time values may be adjusted from OFF to 10 minutes to 240 minutes in increments of 10 minutes.
