POST INSTALLATION
If the value read from the pressure gage is outside of the accept­
able pressure range, use the adjustment screw on the relief
valve to change the relief setting. Turning the adjustment screw
clockwise will increase the pressure setting. Turning the adjust­
ment screw counterclockwise will decrease the pressure setting.
Always adjust the pressure relief valves such that the final
adjustment made is an adjustment from a lower pressure
setting to a higher pressure setting. Read below for fur­
ther clarification.
Note: one quarter turn of adjustment screw equals
approximately 200-500 psi
Scenario 1:
Gage Reading: The pressure read from the gage is below
the acceptable setting.
Action: Bring the pressure up to the acceptable level
by making small clockwise adjustments and checking
the pressure in between each adjustment.
Scenario 2:
Gage Reading: The pressure read from the gage is
above the acceptable level.
Action: First take the pressure below the acceptable
pressure setting by making a few large counterclock­
wise adjustments. After it has been verified that the
pressure setting is below the acceptable level, bring the
pressure up to the acceptable level by making small
clockwise adjustments and checking the pressure in
between each adjustment.
Repeat this procedure on each valve until both are set at the correct pressure.

ADJUSTMENT OF RELIEF VALVE PRESSURES
If the pressure seen at the test port fails to change after adjusting the relief valve,
check to see that the test port you are checking is properly plumbed to the relief valve
that you are adjusting. Failure to do so can result in pump damage.
