Manual Operation
Figure 3
Note: The valve can be manually operated using the external or internal bleed
controls. Refer to Figure 3.
Flow Control Screw
Bleed Screw (external bleed): Turn the bleed screw counterclockwise one full
turn or until water begins discharging past the bleed screw threads.
Note: Removing the bleed screw is not required for manual operation, but can be
removed to help flush debris from the upper diaphragm area.
To close the valve, turn the bleed screw clockwise until it stops. Do not over-tighten!
Bleed Handle (internal bleed): To open the valve, move the bleed handle coun-
terclockwise to the stop. The valve will open as discharge water is routed internally
downstream. To close the valve, move the handle clockwise until resistance is felt.
Do not over-tighten!

Flow Control Adjustment
The valve is set for maximum flow at the factory. If flow adjustment is required, use
the following procedure:
1.
While the valve is operating, use a small screwdriver to turn the flow control
screw clockwise to decrease flow or counterclockwise to increase flow.
Note: The flow control screw requires approximately seven turns to adjust from maximum to minimum flow.
CAUTION: Do not use the flow control to shut off the valve. Do not force the flow control screw past the end of normal
adjustment travel. Damage to the flow control components can occur.
