valve in FILL. As _e rotorand disc rotates, the portopens for FILTERED
water fill through the venturi. Fill flow continues to the solution bottle,
regulated by the fill flow plug. The bottle refills until the float becomes
buoyant and forcos the bibwasher c-ring seal againstthe seat. If it fails to
seal, excessive fill water goes to the drain untilthe valve exits the till cycle.
As the water stands in the bottle, it slowly dissolves about 2 oz of the
potassium permanganate powderat the "A"se_ng (1 oz. at the "B"se_ng).
