Center the bar on the valve and rotate it so the prongs are pointing upward.
One at a time, attach the flapper arms to the ends of the bar. Flapper should
move up and down freely on the flush valve body.
Install the S-hook to the flapper chain at the same location as the original
flapper and attach the S-hook to the trip arm.
Turn on the water supply.
Flush the toilet several times to verify proper operation. Make any
