Bunn Dual SH Installation And Operating Manual page 9

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. In the Set-up Menu, go to "REVIEW RECIPES" - "MODIFY" (See page 10) to change grind and run times for
each hopper.
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.
