Setting the Float Control Valve
Step 1
Closing Speed
–Turn the adjustment screw on the Closing Speed Control OUT, counterclockwise, 1½ to 2½ turns from full closed
position.
Step 2
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 3
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).
Step 4
Slowly open downstream isolation valve to establish flow through
the system.
