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.
