12. ACTIVATION ASSEMBLY REPLACEMENT
A. Tighten the retaining screw at the bottom right using Allen key
B. Slide up wall plate
C. Pull-out wall plate
D. Disconnect Flushometer solenoid connector from the Sensor Assembly
E. Lift-up the Sensor Assembly Override Button to access the activation assembly.
F. Place the adjustment tool on the Activation Assembly and using a screwdriver, turn the assembly fully CLOCKWISE to make sure the valve is
closed.
G. Remove the tool, reconnect the sensor assembly to the solenoid and then press the Override Button to relieve pressure.
H. Remove solenoid connection, lift button up and push-in the activation assembly until fully seated.
I. Remove the orange safety ring by squeezing the pins together and pulling it out. NOTE. ATTACH SCREWS (INCLUDED) TO THREADED HOLES
ON ACTIVATION ASSEMBLY
J. Use attached screws to pull the activation assembly directly out, you may feel some tension. Be sure to pull directly out. Do not turn the
assembly to avoid turning the water flow back-on.
K. Install new Activation Assembly and press until fully seated.
L. Re-install the orange safety ring securely. Safety ring will spin freely in valve body when properly installed.
M. Use the adjustment tool to slowly turn the activation assembly COUNTERCLOCKWISE to open the water ow.
N. Insert Flushometer Solenoid connector to the Sensor Assembly. Do not remove or adjust solenoid.
O. Activate Flushometer by pressing the Override Button.
P. Adjust water ow as needed (See Section 6).
Q. Put down the Sensor Assembly Override Button.
R. Install Wall Plate (See Section 7).
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 rst 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. Range too long; shorten range (See Section 9).
D. Valve Does Not Flush Even After Adjustment.
i. Ensure water supply to valve is turned on.
ii. Activation Assembly sleeve is in closed position. Turn counterclockwise to open water ow.
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 O-ring from groove and wash under clean running water. Replace piston if
cleaning does not correct the problem (See Section 11).
ii. Supply line water pressure has dropped and is not sufcient to close the valve. Close Activation Assembly until pressure is restored.
iii. Piston is damaged. Replace with new proper gpf/Lpf piston.
