33736 072310 ADJUSTMENTS The grind can be set from very fine to very coarse. The amount may be adjusted for use in most commercial coffee brewers. The following procedures should be used to make adjustments. A change in the burr adjustment will also change the amount dispensed. Any adjustment of the burrs should be followed by an adjustment of the timer. Burr Adjustment 1. Unplug the grinder and empty all beans from the hoppers. 2. Plug in the grinder, press and release the GRIND button (with either hopper selected). Run a few grind cycles until all of the coffee in the grind chamber is used. 3. Remove the upper front inspection panel. 4. Loosen the locknut by one turn. 5. Press the GRIND button and slowly turn the adjusting screw in a clockwise direction until a metallic whine is heard due to the rubbing of the grinding burrs. (It may be necessary to start more than one grind cycle to obtain this sound.) 6. Turn plastic grind indicator until screw slot lines up with “O” on the indicator. 7. The following settings approximately correspond to the CBC recognized grinds. All are referenced from the arrow position noted in #6. FINE GRIND: Rotate the adjusting screw 7 hash marks in a counterclockwise direction. DRIP GRIND: Rotate the adjusting screw 8 hash marks in a counterclockwise direction. REGULAR (COARSE) GRIND: Rotate the adjusting screw 12 hash marks in a counterclockwise direction. 1023456789101112131415AdjustingscrewHash Marks P2820 COMMUNICATING WITH COFFEE BREWER When the grinder is used with its companion brewer, the name of the coffee and the size of the batch ground is communicated to the brewer through the chip in the funnel handle as it is placed into the brewer. Therefore, it is necessary to “tell” the grinder the names of the coffees that have been loaded into the hoppers. The names are chosen from the Coffee Chart shown below. Contact the factory if custom names that are not on the chart are required. SELECTING COFFEE NAMES Entering a coffee name from the chart below: 1. Simultaneously press and hold the STOP button and any one of the three batch buttons on the side to be programmed. After 3 seconds all three indicators on the side selected will begin flashing. The display will show a number from the coffee chart below. This number represents the name of the coffee that is to be loaded into the hopper. 2. Press and release the GRIND button to increase the number or press and release the STOP button to decrease it. 3. When the correct number for the coffee being used is displayed, press any of the batch buttons on the other side. All three indicators on that side will begin flashing. 4. Repeat step 2 to enter the name for the coffee being used on this side. 5. To exit the setup mode, press and release the ® button anytime during this procedure. The ® button is a hidden programming pad located at the upper right corner of the BUNN® logo. 33736 072310 Entering a coffee name using a RECIPE CARD. 1. Press the STOP button and place the chip portion of the card under the sensor coil on the front of the grinder. 2. After a short pause, the display will show 3 “dashes”. 3. Remove the card and press any batch switch on the side to be programmed. 4. The display should show the number of the coffee name loaded into the grinder. 5. The grinder display will then return to the normal operating mode. NOTE: If a number is chosen from the chart below, and entered into the grinder, check to be sure the number entered represents the name of the coffee on the chart. 1. Grind into the funnel then insert the funnel into the brewer funnel rails. 2. The display will read the coffee name that was ground into the funnel. 3. If this name is different from the name on the chart, the grinder’s memory needs to be reset. Resetting the grinder memory (to match the chart below) 1. Unplug grinder from the outlet. 2. Press in and hold both the STOP and the GRIND buttons and plug cordset into the outlet. After a short pause, the display will show a series of 3 dashes followed by a series of 9 dashes. 3. When the 9 dashes appear, release the STOP and GRIND buttons, then press and release the STOP button. 4. The display will count down then return to the normal operating mode. The grinder should now be set to match the coffee names with the numbers on the chart below.
