INTRODUCTION
The FPGA will store up to six pounds of whole bean coffee and grind it to a preset grind and amount into
an awaiting funnel and filter or French Press 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 lid
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 Com-
merce 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.
