sure regulators are adjusted by loosening the
adjusting screw on the end of the cone-shaped
cover of the pressure regulator. When the jam nut
is loose, turn the adjusting screw clockwise to
increase or counterclockwise to decrease the set-
ting.
The unload pressure regulator should be set at 150

tems modulation to the service line desired pres-
