Calibration
Procedure
Start NO+
Press middle button
to activate procedure
Follow directions om next page
NOTE
Check for these causes for the difference in the programmed value to the brewed value. These must be corrected first.
-CSD spray head is not in place. This will always result in an increased flow volume
-Flow related error codes 100, 101 - see page 11. Reduced water flow can cause reduced brew volume.
-Clogged or fouled inlet valve or improperly installed inlet valve. See page 16.
-Bypass turned on and flow is off or incorrect. Bypass flow is calculated into total flow and cause short potting if faulty
-Verify that the controls that the brew time is correct, and the display is operating as the control may be turning off.
-Lime scale. This can cause erratic and sometimes random under or over brew volumes. Brew valve can drip, be stuck
open or closed, or fail due to lime scale accumulation. Always correct lime scale faults before changing flow rate.
Changing the flow rate corrects the brew volume if it is different from the programmed value.
Flow rate can be calculated manually or by the FLOW RATE Calibration procedure (E10) on the next page.
The flow rate calibration procedure is an internal program to test for and enter corrections for flow rate inconsistencies.
In the procedure: the equipment will dispense for 60 seconds. The flow dispensed is carefully measured and entered
into the program. The software automatically corrects the flow rate based on the difference of the actual results to the
stored values.
The procedure requires a calibrated 1½ gallon/6liter container. The flow must be very accurately measured. It will be
easiest to manage the readings if the brewer volume units are placed into ounces or liters for units of measure. [Go to
PROGRAM B6]. Units of measure in gallons require a calculation in fractional units of measure - which can be difficult.
TESTING SHOULD BE MADE WITH AN EMPTY BREW BASKET. NO FILTER PAPER. NO COFFEE OR TEA.
Use this formula to manually compensate for minor discrepancies in actual volume versus programmed volume.
See “PROGRAM” E4 to E7 For valve settings and calibration. Factory set brew valve flow rates are in liter/min
Current setting is the flow from E4,E5, E6, E7
