9. Install the coffee BIB’s into the unit, and prime the pumps. Dispense several cups of both regular coffee and
Decaf coffee. If either one or both the DECAF and HOT CHOCOLATE LED illuminates during this process
and dispensing is disabled, the EMPTY PRODUCT WARNING can be reset by priming the appropriate pump
momentarily.
10. After several cups of both coffees have been dispensing, dispense both a REGULAR coffee and a DECAF
coffee. Observe the conductivity reading for each, and record.
11. Take the average of the largest reading from steps seven and eight with the lowest reading from step ten,
and enter this new value in the Empty BIB threshold position, “P10 XXX”, see Programming the dispenser.
Example, if the conductance readings with water from steps six and seven are 225 and 250, and the conduc-
tance readings with coffee from step ten is 355 and 370, you would average 250 and 355, and enter “302”
for the empty BIB threshold in “P10 XXX”.
Field Adjustment of Powder Hoppers
The powder throw for the powder products is pre-set from the factory. It can be checked and adjusted in the
field using this calibration procedure.
Adjusting the Hopper Throw Weight
1. Open the dispenser door to access the digital programming module with LED.
2. Remove the mixing chamber below the hopper outlet elbow.
3. Select PROGRAM on the Function Selector Switch, and NORMAL for the Mode Selector Switch.
4. Press the MENU button to display the Left Hopper Motor calibration menu “04 run”
5. Hold a container under the hopper outlet elbows, and press any beverage button on the front door.
6. The left hopper will run automatically for 10 second, and then stop.
7. Weight the contents of the container. Divide by 10 to determine grams or ounce per second of throw.
8. Press the MENU button to increment the display to menu “O4 XXX”. The number displayed is the power
level drive of the hopper motor. The power level can be increased or decreased by pressing (-) or (+) button.
Each increment is equal to approximately a 1% increase or decrease in hopper motor speed.
9. Press the MENU button to display the Right Hopper Motor calibration menu “05 run”.
10. Repeat steps 5 – 8 to measure and adjust the right hopper throw weight.
11. Replace the powder-mixing chamber, and return the Function Selector Switch to the RUN position.
