* SET NEW RECIPE (COFFEE ONLY)

To set a new COFFEE recipe using a Smart Funnel and a G9-2T DBC or MHG Grinder:

This function allows the operator to set BREW VOL-

UMES, BYPASS %, PULSE BREW/PREINFUSION TIMES AND DRIP OUT TIMES for each coffee name stored in the grinder’s memory.

Certain coffee names are stored in the grinder’s memory. When a particular name of coffee is ground into the Smart Funnel, that name and the batch size selected are transferred from the grinder to the programming CHIP located in the funnel handle. The funnel is then inserted into the brewer’s funnel rails. The SENSING COIL on the brewer reads the information contained in the handle. The name of the coffee flavor will then appear on the display. This allows the operator to set the

BREW VOLUMES, BYPASS % (N/A on ITCB), PULSE BREW/PREINFUSION TIMES AND DRIP OUT TIMES for that particular coffee name. Each coffee name can be set individually to provide optimum brewing quality.

TROUBLESHOOTING

A troubleshooting guide is provided to suggest probable causes and remedies for the most likely problems encountered. If the problem remains after exhausting the troubleshooting steps, contact the Bunn-O-Matic Technical Service Department.

Inspection, testing, and repair of electrical equipment should be performed only by qualified service personnel.

All electronic components have 120-240 volt ac and low voltage dc potential on their terminals. Shorting of terminals or the application of external voltages may result in board failure.

Intermittent operation of electronic circuit boards is unlikely. Board failure will normally be permanent. If an intermittent condition is encountered, the cause will likely be a switch contact or a loose connection at a terminal or crimp.

Solenoid removal requires interrupting the water supply to the valve. Damage may result if solenoids are energized for more than ten minutes without a supply of water.

The use of two wrenches is recommended whenever plumbing fittings are tightened or loosened. This will help to avoid twists and kinks in the tubing.

Make certain that all plumbing connections are sealed and electrical connections tight and isolated.

This brewer is heated at all times. Keep away from combustibles.

WARNING – • Exercise extreme caution when servicing electrical equipment.

Unplug the brewer when servicing, except when electrical tests are specified.

Follow recommended service procedures.

Replace all protective shields or safety notices.

PROBABLE CAUSE

 

REMEDY

1. Type of paper filter

 

BUNN paper filters should be used

2. Coffee

 

For coffee, a sufficient quantity of

 

 

 

 

fresh drip or regular grind should

 

 

 

 

be used for proper extraction.

 

 

3. Sprayhead

 

Bunn-O-Matic sprayhead should

 

 

 

 

be used to properly wet the bed of

 

 

 

 

ground coffee in the funnel

 

 

4. Funnel Loading

 

The BUNN paper filter should be

 

 

 

 

centered in the funnel and the bed

ing.

 

 

5. Water temperature

 

Empty the server, remove its cover,

rails). Press brew. Check the water

 

 

 

 

temperature immediately below

 

 

 

 

the sprayhead with a thermometer.
