ACTIVATION
Once this is completed, remove and discard the protective
label from in front of the lens.
Normal valve operation will occur when the valve senses an
object (person). The LED will blink once. At that point the valve
is charged. When object leaves view of the sensor, valve will
activate. An eight second sensing cycle will prevent the valve
from flushing needlessly when someone walks by.
If special circumstances require adjustment of the sensing
distance, see Appendix A - Changing Activation Distance.
