INTRODUCTION

This equipment will store up-to six pounds of whole bean coffee in each of two hoppers and grind it to a preset grind and amount into an awaiting funnel and filter from most commercial drip coffee brewers. The equipment is only for indoor use on a sturdy counter or shelf. Adequate space must be available above the grinder to raise the lids when adding beans. Use only with whole bean coffee.

The grind is preset at the factory to drip specifications as set forth by the United States Department of Commerce and adopted by the Coffee Brewing Center of the Pan American Coffee Bureau. Adjustments may be made to alter both the amount and grind from the factory setting.

Pressing initiates a timed grind cycle.

Stop Pad (b)

Pressing ends the operation of the grinder.

® PAD (c)

Pressing the ® pad allows programming access (see page 5).

Hopper/Batch Selector Pads (d)

These pads are located on the funnel depictions on each side of the grinder with a total of 6 pads. Selecting one of these pads will select the amount of grind and side from which to grind.

Example: Selecting the lower pad on the left side will grind enough beans from the left side of the grinder to brew the amount programmed into grinder.

Control Board

The control board determines the amount of beans that will leave the hopper in a grind cycle. The timer portion can be adjusted to dispense a different amount from each hopper and each batch size. The scale is from 0.4 to 99.9 seconds. Refer to the Adjustments section for timer setting chart (page 6).

INITIAL SET-UP

1.Open the top lid. Clear all foreign objects and shipping material from the hopper compartment and the entrance to the grind chamber.

2.Plug in the grinder.

3.Fill the hopper compartments with whole bean coffee. (Capacity 6 pounds each). The grinder is now ready for use.

CLEANING

The use of a damp cloth rinsed in any mild, non-abrasive, liquid detergent is recommended for cleaning all surfaces on Bunn-O-Matic equipment. Care should be taken not to scratch the hopper or windows with any abrasive material. Regular cleaning will keep your grinder looking new for years.

COFFEE GRINDING

1.Visually inspect the selected hopper for an ample supply of whole bean coffee.

2.Place a paper filter into the brew funnel. The filter must not be folded-over or tilted to one side.

3.Insert the funnel into the funnel rails and push until it stops.

4.Choose the batch size and side of grinder to use.

5.Press . The grinding action will stop automatically after the preset amount of ground coffee is dispensed

into the funnel.

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 (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 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.Make a mark with a pen on the decal to note the position of the arrow on the grind adjustment screw.

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.

8.Hold the adjusting screw in its set position with a screwdriver while tightening the lock nut.

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 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

TIMER ADJUSTMENT (CONTROL BOARD)

Three different batch settings are selectable for each hopper. Each batch is independently adjustable by setting the length of time a slide gate opens to allow beans to drop into the grinding chamber. A second time setting for each batch determines how long the grind motor continues to run after the slide gate closes. This time is set long enough to insure that all the beans dropped into the grind chamber are ground and dispensed.

1.Determine the grind setting. (The factory setting is drip, to determine other settings, refer to the previous section.)

2.Use the table below to find approximate timer setting for the grind and amount of coffee desired.

3.To enter the setup mode and make an adjustment, press and hold the hidden programming pad under the ®. One of the batch indicators will begin to flash off and on. At this point, release the ® button.

4.Push the hopper/batch selector button for the batch to be adjusted. Note that the digital display shows the current slide gate time setting (in seconds).

5.To increase the time, press . To decrease, press .

6.To change the chamber clean-out time, press the same batch button again and note that the indicator light begins to blink more rapidly and the display shows the current clean-out time.

7.To increase the time, press To decrease it, press .

8.After the cleanout time has been entered, press another batch pad and repeat steps 4 to 7. Otherwise, to exit the programming mode, press and release the ® pad and the grinder returns to the normal operating mode, using the new settings.

NOTE: While in the setup mode, if no buttons are pushed for 60 seconds, the grinder will return to normal operations, retaining any settings made while in the setup mode.
