Use the following process to adjust shut-off and bypass pressures

 

*Remove the pressure adjustment screw completely, mark the screw in 

relation to the switch housing for reference as to number of “turns”, start 

screwing the set screw clockwise “9 to 9½ turns”, as the 3 in picture 2 

indicates. This will increase the pressure to shut-off at approximately 60 

PSI.

*Remove the bypass adjustment screw completely, mark the screw in 

relation to the bypass housing for reference as to number of “turns”, start 

screwing the set screw clockwise “10½ to 11 turns” (See Picture 2, Note 

3.). This will increase the maximum bypass pressure to approximately 67 
PSI.

*How to verify the shut-off and bypass pressures

After adjusting the screw, slowly close the valve until shutoff. The pres

-

sure gauge pointer will indicate shut-off/bypass pressure.
