Operation
1. Invisible light rays are continually emitted from the RetroFlush sensor.
2. When the user comes into range of the sensor’s detection zone (range
12 to 60 inches), the beam is refl ected back to the sensor’s receiver
and converted to a low voltage electrical signal that activates an
eight-second time delay circuit. This time delay prevents the unit from
incidental activation in the restroom. Once this circuit is completed, the
output circuit is signaled and continues in a “hold” mode for as long as
the user remains within range of the sensor. User must be in sensor
range for at least 10 seconds.
3. After the user moves away from the sensor, the absence of refl ected light
starts an electrical “one-time” signal that operates the solenoid operator
(6 VDC) and activates the fl ushing cycle to fl ush the fi xture. The circuit
then automatically resets for the next user.
IMPORTANT NOTE
: The Zurn AquaVantage is engineered for quiet
operation. Excessive water fl ow creates noise, while too little water
fl ow may not satisfy the needs of the fi xture. Proper adjustment of stop
valve is made when:
1. The plumbing fi xture is cleansed after each fl ush without splashing water
out from the lip.
2. A quiet fl ushing cycle is achieved. After adjustment of the stop adjusting
screw: replace the Zurn stop cap screw cover.
Care and Cleaning Instructions
DO NOT
use abrasive or chemical cleaners to clean fl ush valve as they
will dull the luster and attack the chrome or special decorative fi nishes.
Use only mild soap and water, then wipe dry with a clean cloth or towel.
While cleaning the bathroom tile and fl oor, the fl ush valve and electronics
should be protected from splattering of water, cleaner, acids and cleaning
fl uids that can damage the sensor fl ush valve.
