8. Using adjustable wrench, unfasten and remove filter cap.

Trouble Shooting:
Faucet does not operate, red light does not blink:
1. Hands are not placed properly under spout and inline with sensor.
2. Batteries need replacing, replace batteries, see battery replacement instructions.
3. Batteries installed improperly in battery pack, battery harness not plugged in properly, see installation instruction, and battery
replacement instructions.
4. Sensor wire loose, unplugged, plugged improperly, plug sensor wire properly. See installation instructions.
5. Sensor range requires adjustment, see sensor range adjustment instructions.
6. Sink is raised above counter and blocking “sensor’s vision”, reinstall properly.
7. No water, very low water pressure in supply pipes, supply valves closed.
8. Water pressure very high, well above 115 PSI.
9. Screen filter severely clogged up.
10. Supply hoses severely kinked.
Faucet operates on and off “by it self”:
1. Sensor range adjusted too long, and must be adjusted for shorter range. See sensor range adjustment section of this manual.
2. Objects such as sink lip may be present in close proximity to sensor.
3. (Rare) This condition is probably caused by a defective neon light or direct sun light.
Faucet leaks, drips:
Constant leaks or drips indicate defective solenoid valve, send Faucet Automator for repair or contact an authorized plumbing
professional.
Faucet continues to run for 30 -60 seconds after hands are removes then shuts off:
This very rare condition generally occurs due to over sensitivity on the part of the sensor, system water pressure well above 70psi
and an over lit bathroom environment. This condition is always field curable.
1. Turn down water flow rate, see water flow rate adjustment.
2. Replace aerator with 0.5 GPM aerator (when possible).
3. Adjust sensor range to “shorter”. See sensor range adjustment instructions.
Loud thump noise when faucet turns on and off.
This is an issue commonly associated with diaphragm type valves such as washing machine valves, dishwasher valves, etc. The
noise is generally present in the piping system. Clear winner remedies are:
1. Lower water flow rate (see flow rate adjustment section of this manual).
2. Install “hammer arrestors” in close proximity to your automatic faucet. Please consult a plumbing professional for this task.
