Adjustments
Components for adjustment of grinding and brewing timing and of temperature are accessible behind the access
panel located on the lower front panel. The grinder adjustments are located behind the upper front cover.
Setting the Grind Profile
1) Turn off electric power to the unit at the main breaker assigned to the unit.
2) Remove the upper front panel and shield by removing the screws on the sides of the panel.
3) Loosen the adjusting screw lock nut by turning it counter-clockwise.
4) Turn the slotted adjusting screw clockwise to make the grind coarser or counter-clockwise to make the grinds
finer.
5) After adjustment has been made, re-tighten the adjusting screw lock nut.
6) Visually inspect the grind profile with a small portion of coffee and readjust if necessary.
7) Reinstall the upper front panel and shield as it was removed.
Setting the Grinder Throw Weights
The throw weight is adjusted by setting the timer values of the controller after the desired grind profile is achieved.
Refer to
Temperature and Timing Controls section
for more information on controls.
Before adjusting throw weight, grind a batch of coffee and measure the coffee weight. Record this value.
To adjust throw weight:
1) Remove the controller access panel.
2) Slide the brewer selector switch to the appropriate position.
3) Press the Select button momentarily; a LED will light up to indicate which timing selection is being displayed on
the alphanumeric display. Scroll down the selection list to the grinder timer to be adjusted.
4) After selecting the appropriate side and portion timer, adjust the timer value to the desired value by pressing
the Up or Down buttons on the controller. Increasing the timer value increases the coffee throw, decreasing the
number decreases the throw. Hold down the Up or Down button to scroll quickly to the desired value. Once
the desired value is displayed, press the Select button on the controller to save this new value. Grind a batch
of coffee and measure weight dispensed. Repeat this procedure as necessary until desired throw weight is
dispensed.
5) Replace the access panel.
