Adjusting Water Flow Rate - Cornelius ABS 2.0 Service Manual

DJUSTING ATER
Overview: The ABS 2.0 uses 2 MFV water valves for both carbonated water (CW1 & CW2) and plain water (PW1
& PW2). Each valve module has a high-flow orifice and a low-flow orifice. The high-flow orifice provides
approximately 75% and the low-flow orifice provides approximately 25% of the total flowrate. During a beverage
dispense, both valves are activated and together provide the total water flowrate required.
NOTE: The default water volume shown on the Beverage Dispense Calibration screen is 12.00. This is
the target volume after calibration which equates to a water flowrate of 3.0 oz/sec. If the final
water flowrate is different than 3.0 oz/sec, this procedure will update the default value.
1) From the Beverage Dispense Calibration screen, select the button for Carbonated Water 1. Hold the
water compartment of the ratio cup under the nozzle and press the 4 SECOND DISPENSE button.
Target volume for CW1 is approximately 9 ounces. Turn the CW1 adjustment screw on the MFV valve
clockwise to increase the flowrate or counter-clockwise to decrease the flowrate until the target volume
is reached.
2) Next, select the button for Carbonated Water 1 & 2. Hold the water compartment of the ratio cup
under the nozzle and press the 4 SECOND DISPENSE button. Target volume for CW1 & CW2 is 12
ounces. Turn the CW2 adjustment screw on the MFV valve clockwise to increase the flowrate or
counter-clockwise to decrease the flowrate until the target volume is reached.
3) Repeat steps 1 & 2 for the plain water valves PW1 & PW2. The total target volume for plain water is
12 ounces.
