5. Close the piston charge line ball valve.
6. Open the system main drain valve. This drains the sys-
tem of any water that has accumulated. If the system has
operated, open the remote test valve and any auxiliary
drain valves in the system.
7. Close the slow fill ball valve on the air maintenance sys-
tem.
8. After pressure has been released, loosen the valve’s
cover bolts. Remove the valve’s cover, or allow the cover to
pivot on one of the lower bolts.
9. Rotate the clapper out of the access area and inspect
both the rubber clapper facing and the brass seat ring in
the body. Wipe away any contaminants, dirt, and mineral
deposits. Clean any holes in the seat ring that may be
plugged or restricted. DO NOT USE SOLVENTS OR
ABRASIVES.
10. Inspect the clapper for freedom of movement and
physical damage. Replace any damaged or worn parts.
11. Following inspection of the valve, follow the steps in
the “Placing the System in Service” section on page 8.
SLOW FILL
BALL VALVE
• ALWAYS DEPRESSURIZE THE VALVE BEFORE RE-
MOVING COVER PLATE BOLTS. The valve must be de-
pressurized before removing these bolts. The cover
will blow off if these bolts are removed while the
valve is pressurized.
Failure to follow this instruction may result in property
damage or serious personal injury.
• If water is coming from the weep hole under the valve cover,
THE WATER SUPPLY VALVE IS NOT CLOSED! CLOSE THE WA-
TER SUPPLY VALVE NOW!
• Use caution when closing the water supply valve. The clapper
could trip and pinch fingers.
Failure to do so could result in serious personal injury or property
damage.
• The use of solvents or abrasives on or near the seat ring may diminish the ability of
the valve to seal properly.
Failure to do so could result in improper operation or property damage.
