*"Safety mode": If the cell detects for more than 90s, the valve automatically closes. To return to normal operation, remove the elements that
may cause detection by the valve.
** In this case, the valve will be automatically shut off after 90s by the safety system.

8 : TROUBLESHOOTING
Cause
Battery low.
1. The detection is too short.
2. The detection is too long.
3. The battery is out of order
4. The product is in safety mode*
5. The cell is disrupted by reflective
materials
1. The connector between the cell and
the solenoid valve is disconnected.
2. Impurities in the solenoid valve.
3. The central port of the diaphragm is
clogged or torn
4. The water pressure is greater than 8 B.
The central port of the diaphragm is
clogged or torn
1. The cell is dirty or obstructed.**
2. The cell is disrupted by reflective
materials
The filters or the aerator are obstructed
Solution
Replace the battery
Increase the detection
Reduce the detection.
Replace the battery
Wait for 90s
Remove sources of reflection
Connect the cable from the cell and the
solenoid valve.
Remove the solenoid valve head,
remove the plunger and the spring, then
clean them.
Correctly place the spring vertically
when reassembling the plunger.
Clean the port or replace the diaphragm.
Reduce the water pressure.
Clean the port or replace the diaphragm.
Clean the cell or eliminate the causes of
interference.
Eliminate the sources of reflection or
reduce the detection distance
Clean or replace
