To adjust this valve for desired pressure, the intake pressure to the pump must be higher than the normal static
pressure of the municipal water supply. The best method to adjust the valve is to use another pumper to supply water
at the desired pressure.
1. Increase inlet pressure until the master inlet pressure gauge reads the relief pressure you want.
2. With a wrench, slowly open the adjusting screw on the valve until water starts to flow from the valve outlet.
3. Slowly close the adjusting screw until the water stops flowing.
Read the valve manufacturer's documentation for complete instructions.
Secure unattended hoses.
Water discharged from hose will cause hose to whip violently.
Whipping hose can injure or kill.
