START UP PROCEDURE

WATER CONNECTION

The National Sanitation Foundation requires the following for an NSF approved water hook-up:

• A quick disconnect water connection or enough coiled tubing so that the machine can be moved for cleaning underneath.

• An approved backflow prevention device, such as a double check valve to be installed between the machine and water supply.

A 1/4” male flare adapter is provided. Installation to a water filter system is recommended to prevent lime and scale build-up in the machine.

• Water pipe connections and fixtures directly connected to portable water supply shall be sized, installed and maintained in accordance with

federal, state and local codes.

• Flush the water line to purge any debris from the supply line.

Connect a 1/4” pressurized water line to the 1/4” male connection

(on rear of brewer) and turn the water supply on.

a) Minimum water pressure to the machine: 30 psi

b) Maximum water pressure to the machine: 80 psi

NOTE: Single head machines may be used without a pressurized water

supply. (See Pour-Over Mode section)

ELECTRICAL CONNECTION

NOTE: Wiring connections should be performed by a qualified technician.

(Refer to serial tag to verify model number of your machine)

• Remove front panel.

• Connect electrical service through rear of machine to terminal block

(inside front panel) marked L1, N, and L2. (See Figures A and B)

• On dual volt units, flip voltage switch (inside front panel next to terminal

block) to 120V for 120 Volt service or 240V for 120/208, or

120/240 Volt service. (See Figures A, B and table below)

• Re-install front panel.

• Turn on (plug-in) electrical service to brewer.

• Water tank will fill after a 7-second delay. The machine will make a

hissing sound when this occurs. On single head models, allow

approximately 1.5 minutes for the brewer to fill. On two head models, allow approximately five minutes for the brewer to fill.

NOTE: If water supply is inadequate or not connected, display will read “P-O” after 4 minutes of fill time (Refer to Pour-Over Mode

section). If Fill Cycle times out and display reads “P-O” before tank is full, turn unit OFF then ON again to reset and continue filling.

• The tank will begin heating slightly before machine fills.

• Turn brewer on by pressing ON/OFF switch in front of machine. (Light will illuminate)

• The brewer settings can be adjusted through the front touch pad. (Refer to Adjustments section)

• 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.

LOW TEMP/ NO BREW MODE:

When set to “ON”, a brew cycle cannot be initiated until tank is hot and “READY” light is ON. When set to “OFF”, a brew cycle may be initiated at any time.

POUR-OVER MODE:

Note: Not available on B-6, B-DAP, and B-DGP (twin) models.

Brewers are capable of operating without a pressurized water source.

If there is no pressurized water source, brewer can be set-up as a pour-over.

1. If no water is in the tank to begin with, pour about three decanters of fresh water into the basin

(Fig. D). A small amount of water should remain in the basin.

2. If tank already has water, pour fresh water into basin (Fig D) until a small amount is in the basin

and no longer drains into the tank.

3. Place server under the EMPTY brew basket.

4. Turn power on to machine

5. Go into Settings Mode and change “P-O” to “YES”.

6. Display will read “P-O”. (Fig C)

7. Wait until Ready light illuminates.

8. Press-and-release Brew button to initiate a brew cycle.

9. Water should stop flowing before READY light stops flashing to create a “short pot”.

10. After tank water recovers and READY light illuminates, brewer is ready to brew coffee. See Brew Procedure.

If brewer is in operation (connected to a pressurized water source) and water is shut off for four minutes, display will read “P-O” (Fig C) and

brewer can be used as a pour-over:

1. Place server under the EMPTY brew basket.

2. Wait until Ready light illuminates.

3. Press-and-release Brew button to initiate a brew cycle.

4. Water should stop flowing before READY light stops flashing to create a “short pot”.

5. After tank water recovers and READY light illuminates, brewer is ready to brew coffee. See Brew Procedure.

If water pressure problem is resolved, simply press Off then On.

Brew Procedure while brewer is in pour over “P-O” mode:

1. Wait until tank water heats up and READY light is on.

2. Place brew basket in place with ground coffee inside filter.

3. Pour a full (64oz) maximum container of fresh water into basin at top/front of brewer. (Fig D)

4. Place container under brew basket.

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

COUNTER:

The brewer is equipped with a counter that displays the total number of brew cycles for each dispense head. After turning the brewer on, the number will scroll across the display two times and then clears.

CLEANING CABINET

• The outside of the brewer can be cleaned with a damp cloth, a household dusting spray or a stainless steel cleaner. Do not use an abrasive such as Scotchbrite or Brillo pads. These may mar the finish.

• Wipe the underside of the cabinet hood with a clean cloth. Be especially careful when using soap or detergent around the sprayhead. Any soap left on the deflector may impart an unpleasant taste to the first brews.

CLEANING WARMERS

The warmer plates are easy to clean and will maintain its appearance longer if cleaned regularly. Coffee stains can be wiped off with a damp cloth. Use detergent or sanitizer for heavy deposits, but refrain from using abrasives.

CLEANING BREW BASKET, AIRPOTS AND DECANTERS

Use commercial grade urn cleaner (as directed by manufacturer) and rinse thoroughly.
