The Flexible Numeric Display (FND) allows for the adjustment of the flush time,

which can help reduce scale accumulation in the water trough, preventing it from

clogging other vital parts, such as the water pump and water distribution tube.

See next page for all FND functions.

Additionally, the FND allows for the adjustment of the water fill time, which

will extend the fill time for a set amount once the high-level sensor is sensed.

The fill time can be adjusted between 0-30 seconds, in 1 second increments.

The flush time can be adjusted between 0-90 seconds, in 1 second increments.
