F61 Series Standard Flow Switches Installation Instructions 5
To verify that the flow rate is set above the factory
minimum (see Figure 9):
1. depress the main lever numerous times. If the
lever fails to click upon return at any time, the flow
rate is set below the factory-set minimum.
2. raise the flow rate to approximately the factory
minimum by turning the adjusting screw clockwise
until the lever clicks upon return every time.
