The pressures listed on the previous page can be tested using a manometer.
To attach manometer, first remove the inspection cover from back panel. The cover is
located directly behind the control and is removed by unscrewing the two top screws.

pressure taps as shown below.

the outlet (operating) pressure by adjusting the valves internal regulator. To locate the
valves regulator adjustment screw the plastic control cover must be removed from the
front of the valve. This is done by removing the bottom screw and inserting a small flat
head screwdriver into the slot at the top on the front of this cover and pulling the cover
