Causes / remedies
pH Value
flashing
The device has detected an abnormal value of the pH, either too high (ex : 8.2), or too low
(ex: 6.0).
1/ Check the pH value directly in the pool with your usual analysis kit.
2/ In case of agreement, stop the device. Add the pH acid corrector (pH too high) or pH basic
(pH too low) directly in the pool to the buzzards of expulsion. Wait for 30 minutes. Restart
the device up.
3/ In case of no agreement, check if pH probe works by calibration measurement (see § 6.2,
17p.).

Flashing
The device detected that the last pH correction attempts are unsuccessful.
The REGULATION is interrupted.
To acknowledge an alarm, press in . pH value appears.
1/ Check that the pH corrective tin is not empty.
2/ Using “MA” function, check that liquid be vacuumed up and injected well.
3/ Measure pH with the help of your analysis kit, and compare it to value indicate on device.
If value is different, calibrate pH probe (see §6.2, 16p.)
If value is identical, ask only to professional person in case of problem start again.
4/ Check well similarity between CP,Co,OP parameters.
5/ Check that water TAC is not to high ( §5.1, 16p.)
