INTRODUCTION

This equipment will store up-to five pounds of whole bean coffee in a 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.

Please visit www.bunn.com/product-manuals to find a complete programming manual that will
guide you through settings to adjust or modify. Topics include: program lockout, modify recipes, set
password, set language, test outputs/frequencies, grind counters, serial asset number, software
update, and more.
