• When checking the pressure test points, undo the screw one half turn and slip the tube over the nipple.

• Turn on power and energize main solenoid. Do not energize the HI solenoid.

• Remove low outlet cover screw, and turn screw clockwise to increase pressure, or counterclockwise to decrease pressure. Replace low outlet cover screw.

• Energize main solenoid and HI solenoid.

• Remove high outlet cover screw, and tum screw clockwise to increase pressure, or counterclockwise to decrease pressure. Replace low outlet cover screw.

• Turn off all electrical power to the system.

• Remove all hoses from test point and retighten low and high outlet cover screw.
