•Main Flush
The sensor will provide a main fl ush after a user is in range
for eight or more seconds. The eight-second delay prevents
actuation of the fl ush valve by a person walking past the
sensor.
•Automatic 24-Hour Flush
The sensor will provide an automatic fl ush 24 hours after
the last fl ush. The automatic fl ush feature can be manually
switched on or off in the fi eld, depending on owner
preference. The option is controlled by switch number one.
•Courtesy Flush
The sensor will provide a courtesy fl ush within two seconds
after a person is fi rst detected. The courtesy fl ush freshens
the bowl and removes any residue from the fi xture. The main
fl ush will occur when the user steps away from the fi xture.
The courtesy fl ush feature can be manually switched on or
off in the fi eld, depending on owner preference. The option
is controlled by switch number two.
•Maintenance Override
One may initiate an immediate fl ush by placing a magnet
in front of the sensor window for one-half to three seconds.
This feature is typically used by the cleaning staff who do
not wish to stand in front of the sensor to cause actuation.
One may prevent operation of the fl ush valve by placing a
magnet in front of the sensor window for longer than three
seconds. This feature is typically used by maintenance or
cleaning staff who wish to prevent automatic actuation of
the valve. This feature is automatically defeated after ten
minutes.
If one wishes to defeat the feature prior to the ten-minute
time out, simply place a magnet in front of the sensor
window for one-half to three seconds.
Zurn RetroFlush System Features
•Indicator Light
The sensor unit includes a red indicator light having three
functions:
1. Range Adjustment: For the fi rst ten minutes of operation,
the red light will fl ash when an object is detected.
2. Low Battery Indication: When the batteries have reached
the caution level, the red light will fl ash when an object is
detected.
3. Abnormal Refl ection Indicator: When a refl ective surface
is present for longer than 30 minutes, the red light will fl ash
indicating that an object is being continuously detected.
•Adjustable Range
The detection distance is fi eld adjustable from 12 to 60
inches. 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 ten minutes
after battery installation, a blinking red light in the sensor
window will appear when an object is in view. For an
additional ten minutes of blinking, push the reset button.
Stand in front of the sensor and move forward and backward
to determine range.
•Urinal Water Saver
This feature is intended for a high-use application, such as
a stadium or civic arena, where a continuous line of users
wait to use a urinal. When a sensor-operated urinal is
used continuously, water consumption can be signifi cantly
reduced. Water is conserved by fl ushing a partial volume of
water after two consecutive users have been sensed and a
new user enters the range of the sensor within fi ve seconds
of the previous user leaving. This partial fl ush clears the
urinal and allows for the next repetitive fl ush to continue to
move the waste water through the drain line. This feature is
automatically defeated if a user does not enter the sensor
range within fi ve seconds of the previous user leaving. The
urinal water saver feature can also be manually switched
on or off in the fi eld, depending on owner preference. The
option is controlled by switch number four.
