amps minimum.

2. Test the unit by running some whole bean coffee through the grinder. If any problems are encountered, refer to the troubleshooting
section complete at www.wilburcurtis.com or call Technical Support at 800-995-0417.

complete stop before removing the brewcone.

5. Transfer the lled brewcone to the brewer and press the desired brew button. The brew

ADJUSTING THE GRINDS

1. Empty hopper of coffee beans. Run grinder to clear grinding burrs of coffee.
