To close the valve, turn the bleed screw clockwise until it stops. Do not
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
Flow Control Adjustment
The valve is set for maximum flow at the factory. If flow adjustment is required, use the following procedure:
