No display
Check that the On / Off switch is on.
Check the connection cable between the display and the control box.
Check that the external 4A fuse (7) is not defective.
Check the power supply: 210-230 V 50 Hz.
If the problem persists, contact your pool installer/builder.
Excessive chlorine
Low electrolytic cell current.
If your pool has an automatic redox control system, check the redox setting.
Check the redox probe and calibrate, if necessary.
Salt chlorination does not reach the required production rate
Check the concentration of salt in the water (3.2 g/l recommended).
Check the condition of the cell (it may be dirty or covered in scale).
Clean the cell according to instructions.
Check the flow switch and clean if necessary.
Check that the cell is not worn (contact your pool installer/builder).
Cell scaled up in under a month
Very hard water with high pH and total alkalinity (balance and adjust the pH and total alkalinity of the water).
Check that the system automatically changes polarity (see display).
Impossible to attain a free chlorine level of 1 ppm
Increase the filtration time.
Increase the chlorination production rate.
Check the concentration of salt in the water (recommandé 3.2 g/l).
Check the level of isocyanuric acid in the pool (see table).
Check that the reactive agents in your test kit are not out of date.
Adjust the chlorine production according to the temperature and the number of pool users.
Adjust the pH to ensure that it is always below 7.8 (7.2 recommended).
Alarm AL3: pH dosing pump stopped
The maximum time allowed to attain the pH set point has been reached. The pH acid dosing pump is stopped to avoid overdosing and
acidifying the water.
Please carry out the following checks to avoid equipment failure:
Check that the can of liquid pH is not empty.
Check whether the pH read on the machine corresponds to the pH in the pool (use a pH analysis kit). Otherwise, please calibrate the
pH probe or replace it, if necessary.
Check that the pH pump is running normally.
Check the correction time setting.
To delete this message and reset the dosing, press the "Return" key.
The screen indicates LOW
Check the water balance and salinity.
Check that the cell is free of scale and clean it if necessary.
See "Salt chlorination does not reach the required production rate".
Water temperature too low.
White flakes in the pool
This occurs when the water is unbalanced and very hard.
Balance the water, check the cell and clean it, if necessary.
The screen indicates FLOW
Check the flow switch.
Check that the filter pump is working.
Check that the pipes are not obstructed (valve closed, basket or strainer full, etc.).
Check 4 A fuse (6).
