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.

As directed in the International Plumbing Code of the International Code Council and the Food Code Manual of the Food and Drug Administration (FDA), this equipment must be installed with adequate backflow prevention to comply with federal, state and local codes. For models installed outside the U.S.A., you must comply with the applicable Plumbing /Sanitation Code for your area.

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

2.Turn on the water supply.

INITIAL SET-UP

1.Insert an empty funnel into the funnel rails.

2.Place an empty server under the funnel.

3.Connect the brewer to the power source.

4.Turn on the main ON/OFF switch located on the left side of brewer (If equipped).

5.Water will flow into the tank and stop when the tank is filled to its capacity. Display will show "PLEASE WAIT...TANK FILLING" until tank is filled with water.

6.Wait approximately twenty minutes for the water in the tank to heat to the proper temperature. Display will show "READY TO BREW...WATER TEMP: 200°" when tank is at operating temperature. Some water will drip from the funnel during this time; this is due to expansion and should not occur thereafter.

7.Place a small container beneath the faucet and open the faucet handle. Release it when you hear the tank refilling.

8.Water volumes and flow settings have been preset at the factory. Refer to adjustments for the Set

Brew Volumes section of this manual should the volume need to be increased or decreased.

9.The brewer is now ready for use in accordance with the instructions for Coffee Brewing.

10.Repeat steps 5-9for remaining side on Twins.

If setting up new brewer in high mineral locations, refer to programming (Enable Brew Logic). Pertains to units with software version 1.06 & up.

Brew water temperature is factory set at 200ο F (93.3ο C) Areas of high altitude will require lowering this temperature to prevent boiling. This chart should be used as a guide when readjusting the brew water temperature.

P3969.50

 

(A) ENABLE BREW ON/OFF SWITCH

Pressing the "ENABLE BREW ON/OFF" switch (indicator on) supplies power to the brew station warmer and enables the brew circuit. Pressing the switch again (indicator off) stops 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 server until the funnel is empty.

(B) BREW SWITCH

Momentarily pressing and releasing the switch starts a brew cycle when the "ENABLE BREW ON/OFF" indicator is on.

(C) ADDITIONALWARMER or HALF/FULL BATCH SWITCHES

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

NOTE 1: APS & TC models have no warmers.

NOTE 2: These switches are Half/Full Batch on "Single Axiom" models.

(D) MAIN ON/OFF SWITCH

This switch, located on the left side of the brewer, turns power on and off to all components in the brewer.

COFFEE BREWING

 

1.

Begin each brew cycle with a clean empty brew

 

 

funnel.

 

2.

Insert a BUNN filter into the funnel.

 

3.

Pour (or grind) fresh coffee into the filter and level

 

 

the bed of grounds by gently shaking.

 

4.

Slide the funnel into the funnel rails until it stops.

 

5.

Place an empty server under the funnel.

 

6.

Verify that the "ENABLE BREW ON/OFF" indicator

 

 

is on.

 

7.

Momentarily press and release the "BREW" switch.

 

 

The display will read "NOW BREWING", and show

 

 

the time remaining in the brew cycle.

 

8.

Following the brew, the display reads "DRIPPING"

 

 

which shows the time remaining until the coffee no

 

 

longer drips from the funnel tip.

 

9.

After the coffee finishes dripping from the funnel

 

 

tip, carefully remove the brew funnel and discard

 

 

the grounds and filter.

 

NOTE: Some models are equipped with a backup

 

pour in feature, in case the plumbed water supply is

 

disrupted. In this event, disregard steps 7-8,and pour

 

in 64 ounces of fresh water.

CLEANING

1.The use of a damp cloth rinsed in any mild, nonabrasive, liquid detergent is recommended for cleaning all surfaces on Bunn-O-Maticequipment.

2.Check and clean the sprayhead. The sprayhead holes must always remain open. Insert the short end of the sprayhead cleaning tool into each of the five water outlets of the plastic sprayhead to remove any mineral deposits (Refer to Fig 1)

3.Insert the long end of sprayhead cleaning tool into the sprayhead fitting, and rotate several times to remove any mineral deposits from the fitting (Refer to Fig 2).

NOTE: In hard water areas, this may need to be done daily. It will help prevent liming problems in the brewer and takes less than a minute.

NOTE: In the event that the"Brew Logic" circuit activates (compensating for high lime build up), it will temporarily disable the"Recovery Booster" and"Pulse Brewing" systems until the unit has beende-limed.Refer to the Troubleshooting section for more details.

FIGURE 1

FIGURE 2

TANK DRAIN

1.Loosen screws that secure the front access panel. Remove the panel.

2.Unfasten the hose clamp at the end of the drain hose. Remove the plug.

3.Place the end of the drain hose in a container that has a minimum capacity of 200 oz (5.9 L).

4.Release the white clamp to drain water from the tank.

5.When tank is empty, close the white clamp, replace the plug, and tighten the clamp at the end of the drain hose. (Repeat steps 2-5for remaining side on Twins)

6.Replace the front panel and tighten screws.
