7/ DIAGNOSTIC OF THE FAILURES
Securities
AL means that the device has detected a production anomaly.
Causes
Explanations/Remedies
A
1
Lack of
water
Chlorine production is stopped.
Check full and constant flow of water in the cell.
Lack of
salt
Chlorine production is stopped.
Check the salt rate in the pool with your usual analysis kit.
Controlle
r
problem
Chlorine production is stopped.
You have to contact a professional so that he proceeds to the repair of the Controller.
Cell
Problem
Chlorine production is stopped.
1/ Check visually that the cell is not scaled (to descale, see §6.2).
2/ Check that the connexions to the borders of the cell are not oxidized and well squeezed.
3/ In most of cases, this code shows that your cell is totally used and/or scaled and cannot produce
chlorine.
You have to contact a professional to proceed to the replacing of its.
A
2
Short
circuit
security
Chlorine production is stopped.
1/ Check that the connexions to the borders of the cell are well squeezed.
2/ In last case, electronic default can be in cause. You have to contact a professional to
proceed to the replacing of its.
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).
Regulation is stopped.
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. In case of normally pH value, you have to calibrate pH probe (see § 6.3).
Message
“AL”
Flashing
The device detected that the last pH correction attempts are unsuccessful.
The REGULATION is interrupted.
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 §6.3)
If value is identical, ask only to professional person in case of problem start again.
If this alarm starts in an inappropriate way, it is possible to deactivate parameter menu.
Originally, the alarm A1 is deactivated by default. If necessary, this function invites the user to activate
manually this order.
A shock chlorination and a strong correction of the pH by adding acid or soda in skimmers risk activating the
alarm without any reason.
