for one minute, (purge into a bucket if available). Purging valve in this way will remove particles
that would otherwise find their way into the flush valve causing immediate damage.

tools, that can cause damage
to the finish on the flush
valves
Please remember the following: Valves are shipped with batteries pre-installed and a cover over the sensor
eye. When necessary to remove batteries never attempt to remove batteries by pulling hard on battery wire.
