INTRODUCTION

This equipment will store up-to six pounds of whole bean coffee in the hopper 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.

Carefully read and follow all notices on the grinder and in this manual. They were written for your protection.

All notices on the grinder are to be kept in good condition. Replace any unreadable or damaged labels.

COFFEE GRINDING

1. Visually inspect the 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 until it stops.

4. Select batch size desired (e).

5. Momentarily press the “START” switch (a). The grinding will begin after a moment. The actual weight of the coffee being ground into the funnel will be shown on the display during grinding. The grinder will automatically stop when the correct weight is reached. DO NOT TOUCH THE FUNNEL OR FUNNEL HANDLE DURING

GRINDING. THIS WILL CAUSE THE INCORRECT WEIGHT OF COFFEE TO BE GROUND.

6. Remove the funnel from the grinder and level the bed of grounds by gently shaking.

7. The loaded funnel is now ready for use in any commercial drip coffee brewer according to the manufacturer’s instructions.

ADJUSTMENTS

The grind can be set from ﬁne to very coarse. The grind may be adjusted for use in most commercial coffee brewers. The following procedures should be used to make adjustments.

Burr Adjustment

1. Unplug the grinder and remove the hopper by pulling forward with the handle.

2. Plug-in the grinder, place funnel with ﬁlter into the funnel rails. Momentarily press the “START” button and release, run grind cycles until all of the coffee in the grind chamber is dispensed.

3. Remove two black screws from the lower control panel bezel.

4. Remove the control panel and hang the control panel on front of grinder by inserting metal tabs on the back of control panel into slots on the front of grinder.

5. Make sure funnel with ﬁlter is still in place in the funnel rails. Go to the “GRIND MOTOR” menu under the level 1 “SERVICE TOOL?” menu, and press the button under “ON” to start the motor. Slowly turn the adjusting screw in a clockwise direction until a metallic whine is heard due to the rubbing of the grinding burrs. Reverse the adjusting screw just until the whining stops. Turn off the motor and exit to home screen.

6. Remove the white plastic cap, and replace it on the end of the grinder with the “0” aligned with the adjusting screw slot.

7. The following settings approximately correspond to the CBC recognized grinds.

FINE GRIND: Rotate the adjusting screw to the “7” in a counterclockwise direction. DRIP GRIND: Rotate the adjusting screw to the “8” in a counterclockwise direction. REGULAR (COARSE) GRIND: Rotate the adjusting screw to the “12” counterclockwise direction. NOTE: Exact adjustment will vary according to bean roast or added ﬂavoring

8. Reinstall front control panel.
