Field Calibrating the Empty BIB Warning

The dispenser will automatically turn on the Left or Right “REFILL LED”, see Operating Controls and Interface, when the corresponding BIB is Empty. The Refill message is triggered when the FlavorGardTM sensor reading drops below the minimum setting. The factory set minimum is 500 and should be correct for most locations. However, in some areas the hardness of the local water supply may effect this reading. If the Refill message doesn’t come on when the BIB is empty or the message comes on too early and there is still concentrate left in the BIB, use the following procedure to find the correct Empty BIB threshold.

Calibrating The Empty BIB Threshold

1.Remove the lower splash guard assembly to access the digital programming module with LCD display.

2.Open the cabinet door and set the Function Switch to the “Rinse” position. Close the door.

3.Place a large container under the Left dispenser tip, then activate and hold the left dispenser.

4.Dispense long enough to rinse all the concentrate out of the mix chamber and for the Conductance reading to stabilize and stop dropping.

5.Record the nominal Conductance value displayed. (NOTE: It is typical for this value fluctuate (+/- 25) points about the nominal value}. This is the conductance reading of the water in your area.

6.Repeat steps 3, 4 & 5 for the Right dispenser.

7.Add 100 points to the larger of the Left or Right side Conductance value. This is the new Empty BIB threshold value for your dispenser.

8.Enter this new value into the Empty BIB Alarm threshold, see Programming the Dispenser.
