. Replace electronics
access cover and tighten securely with vandal-resistant hex wrench.
Before the supply water is turned on, be sure all stop valves to the fl ush
valves are closed off tight. The stop valves can be opened and closed by
using the adjusting screw located at the center of the stop valve cap, behind
the adjusting screw cover if already installed. Stop valve adjustments can
only be made by using the adjusting screw.
It is not necessary to remove
the stop valve cap when making adjustments. If for any reason it
becomes necessary to remove the stop valve cap, be certain the water
is shut off at the main supply valve.
9. When all fl ush valves are connected to the fi xtures and water pressure is
available, it is recommended that the supply piping be fl ushed to remove
dirt, pipe chips, etc., from system. This procedure should also be repeated
when the system is drained for seasonal use, as occurs in athletic fi elds,
recreation parks, etc.
10. The AquaSense “A” fl ush valves are preset for fi xture volume as
marked on the valve cartons. The valve does not require regulation for
variation in water pressure within its operating range. To set the fl ush
valve for proper operation, open the stop valve completely by using the
adjusting screw and fl ush the AquaSense “AV” several times. Gradually
adjust the stop valve closed, using the adjusting screw, so that the
rate of water fl ow into the fi xture is not excessive, yet is suffi cient to
adequately evacuate the waste. The fi nal setting for closets should
provide a rate of water fl ow suffi cient enough to evacuate thirty sheets
of toilet paper from the fi xture. The fi nal setting for urinals should be
such that the fi xture will not overfl ow when the valve is actuated twenty
times in succession. The stop cap screw cover should be replaced after
fi nal adjustments have been made.
Sensor Range Adjustment
The range is factory set for urinal or closet applications. If necessary, the
sensor range can be adjusted. Pressing the reset button will initiate a
ten minute set-up period. During these ten minutes a red light will fl ash
through the sensor lens when an object is in view of the sensor. Use this
feature to properly set the sensor range. Slowly rotate the range adjustment
clockwise to increase range and counterclockwise to decrease range. The
range adjustment will stop at minimum and maximum settings. Do not turn
beyond these stops. For an additional ten minutes of blinking, push reset
button. Stand in front of sensor (minimum 10 seconds) and move forward
and backward to determine range.
