Cornelius R-134A service manual UF-1 DISPENSING VALVE

4.Install syrup separator on dispensing valve in place of the nozzle.

5.Measure the water flow rate by dispensing water into a graduated cup for a set period of time. Factory-set flow rate is approximately 1.25 ounces per second.

6.Adjust the water flow control adjusting screw clockwise for a greater flow or counterclockwise for lesser flow. Limit your adjustment to 1/4 turn at a time, then recheck the flow rate. Only the water flow rate is to be adjusted now. Syrup flow rate is adjusted in the Water-to Syrup “Ratio”(Brix) Adjustment section.

1.Remove cover from the dispensing valve by lifting the front cover up 1/4 inch and pulling forward.

2.Install syrup diversion tube assembly on the dispensing valve by pushing rubber end of the syrup diversion tube onto the syrup outlet of the inner nozzle.

3.Measure the water flow rate by dispensing water into a graduated cup for a set period of time.

NOTE: Adjusting screw stops are built into the valve to prevent leakage when the screws are adjusted too far clockwise. Stop adjusting clockwise when turning resistance increases. Turn the screw coun- terclockwise 1--1/2 turns after the stop are contacted.

4.Turn the water flow regulator adjusting screw to the left (counterclockwise) to decrease the water flow rate or turn the adjusting screw to the right (clockwise) to increase the water flow rate, then recheck the flow rate. Adjustments should be no more than 1/4 turn at a time.

5.Remove syrup diversion tube from the dispensing valve, then install cover on the dispensing valve.
