IMPORTANT:
• All plumbing is to be installed in accordance with applicable codes and regulations.
• Water supply lines must be sized to provide an adequate volume of water to each fixture.
• Flush all water lines prior to valve installation to ensure proper operation.
- Particulates in the water can block small orifices within the valve which may result in continuous running.
• The use of toothed tools during installation or service of the faucet or its components may lead to premature failure.
Prior to Installation:
Before installing your Zurn®Aqua-FITTM Faucet: the items listed
below should already be installed on site.

OPERATION
1.) Invisible light rays are continually emitted from the faucet
sensor.
2.) When the user’s hands come into range of the sensor’s
detection zone (factory set at approximately 6”), the beam is
reflected back to the sensor’s reciever and converted to a low
voltage electrical signal activating a solenoid valve.
3.) After the user removes their hands, the absence of reflected
light stops the low voltage electrical signal, closing the valve.
The circuit automatically resets for the next user.
4.) If an object is in view continuously for thirty seconds, the
faucet will automatically shut off. The faucet will remain off until
the object is removed. After the object is removed, the faucet
functions normally.

POTENTIAL SITUATIONS POSSIBLE CAUSES SUGGESTED SOLUTION TIPS
Solenoid is not connected properly Place hands in sensor range. If clicking occurs, solenoid is connected
correctly. If no clicking occurs, disconnect the sensor cable from the
black box and w ait 15 sec before reconnecting. Once reconnected try
activating again.
Batteries are low on pow er Change out batteries
Sensor and electronic connector cable has
bent or broken pins Check to see if pins are missing, bent, or broken. If yes, then the electronic box needs replaced
Solenoid is lodged w ith debris Check solenoid for debris and clean if necessary and reassemble
If faucet is hardw ired, could have voltage
range issues Check voltage levels and adjust if necessary to fallw ithin recommended ranges.
Sensor lens could be obstructed by
environmental factors such as high reflective
surfaces or bright lighting conditions
If this is the case, then adjust the dip sw itch settings for sensor
resolution per the diagramin the installation manual(sw itches 7 and 8)
Sensor lens could have surface damage,
scratches, or deposit build ups fromchemical
cleaners
Inspect the sensor lens underneath the spout tip. May require cleaning
(damp rag) or replacement
Remove the battery tray and inspect for visual signs of rust, water,
debris. Replace battery tray if these symptoms are found.
Remove battery tray, if no visual signs can be detected, try using a
metallic object to tap the coils to exhaust any fault charges. Reassemble
Sensor faucet does not
activate after initial installation Sensor lens may not have had enough time to calibrate prior to a user or target trying to
initiate activation
Disconnect the sensor and electronic box cables and wait for 15
seconds. Reconnect the cables, but allow for another 15 seconds
before placing hands or a target within the sensor range. You should
hear a click of the solenoid once calibration is complete.
Solenoid is lodged w ith debris Check solenoid for debris and clean if necessary and reassemble
Sensor and electronic connector cable has
bent or broken pins Check to see if pins are missing, bent, or broken. If yes, then the electronic box needs replaced
If this is the case, then adjust the dip sw itch settings for sensor
resolution per the diagramin the installation manual(sw itches 7 and 8)
Loosen the mounting nuts and try sliding the faucet back in the lavatory,
sink, or counter top holes back tow ards the wall and retightening. Could
be detecting the grid drain in the sink bow l.
Mounting hardw are is not tightened sufficiently
(faucet shank, electronic box, supply hoses,
etc)
Check and ensure the nuts and joints are tight and secure fromthe
supply stop allthe way to the faucet shank.
Missing the w asher located in the solenoid box
nut where it assembles to the faucet shank. Make sure w ater supply stops are shut off. Check to ensure the w asher is installed. If not, need to replace w ith a new washer.
Sensor faucet is leaking
underneath the sink or
counter
Sensor faucet is not
activating or running
Coils in battery tray are promoting a voltage
drain
Faucet runs continuously
(longer than the selected time-
out that is programmed)
Sensor faucet is experiencing
randomactivations when a
user or target is not within
sensing range
Sensor lens could be obstructed by
environmental factors such as high reflective
surfaces or bright lighting conditions
