All settings are made with the diaphragm in a vertical position. The switch is shipped with the adjustment at minimum (0.05” W.C.)
To adjust, turn adjusting screw with screwdriver. To increase pressure setting, turn adjustment screw down in a clockwise direction.
To decrease pressure setting, turn adjusting screw up, in a counterclockwise direction.
If adjusting screw is removed, apply a non-hardening pipe compound to the threads before replacing. Check for leaks with a soap
bubble test using maximum 20” W.C.)
