13. TROUBLESHOOTING
A. Sensor Flashes Continuously Only When User Steps Within Range.
i. Unit in Start-Up mode; no problem. This feature is active for the first ten (10) minutes of operation.
B. Valve Does Not Flush; Sensor Not Picking Up User.
i. Range too short; increase the range (See Section 9).
C. Valve Does Not Flush; Sensor Picking Up Opposite Wall or Surface, or Only Flushes When Someone Walks By. Red Light Flashes
Continuously for First 10 Minutes Even with No One in Front of the Sensor.

i. Ensure water supply to valve is turned on.
ii. Activation Assembly sleeve is in closed position. Turn counterclockwise to open water flow.
iii. Batteries completely used up; replace batteries (See Section 10).
iv. Problem with activation assembly; replace activation assembly (Section 12).
v. Problem with Sensor Assembly; replace Sensor Assembly (See Section 3).
E. Red Light Blinks four (4) Times When User Steps Within Range (Battery Only).
i. Batteries low; replace batteries (See Section 10).
F. Red Light Blinks four (4) Times When User Steps Within Range (Hardwire and Battery).
i. Battery box not connected; connect battery box to sensor assembly (see section 10).
ii. Batteries low; replace batteries (see section 10).
G. Valve Does Not Shut off.
i. Metering bypass hole in piston is clogged. Remove the piston from the valve and wash under clean running water. Do not attempt to
remove filter screen. Replace piston if cleaning does not correct the problem (See Section 11).
