Setting the Float Control Valve
Opening and Closing Speed – Turn the adjustment screws on the Closing Speed and Opening Speed Controls, if the main valve is so
equipped, OUT, counterclockwise, 1½ to 2½ turns from full closed position.
STEP 1
To ensure proper operation, any trapped air will need to be bled
off the valve cover during startup. The ACV includes a bleed
valve, use a flat head screwdriver to slowly open the valve (See
Figure 1).
STEP 2
Pressure the line, by opening the upstream isolation valve slowly.
Air is vented through the air bleed valve. Tighten the fitting when
liquid begins to vent (See Figure 1).
