No display
Check the connection cable between the display and the control box.
Check that the 4A fuse is not defective (located inside the control box).
Check the power supply: 210-230 V 50 Hz.
If the problem persists, contact your pool installer/builder.
Excessive chlorine
Check and/or adjust the chlorine production setting.
If your pool has an automatic ORP control system, check the ORP setting.
Check the ORP probe and calibrate, if necessary.
The hydrolysis has not reached the required production rate
Check the concentration of salt in the water (depending on the model).
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 chlorine production rate.
Check the concentration of salt in the water (see table Chemical water balance).
Check the level of isocyanuric acid in the pool (see table Chemical water balance).
Check that the reactive agents in your test kit are not out of date.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.
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:
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 make this message disappear and reset the dosing, press on the pH reading circle for 3 seconds.
The screen indicates LOW
Check the water balance and salinity.
Check that the cell is free of scale and clean it if necessary.
See "The hydrolysis has not reached 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 and the gas detector.
Check that the filter pump is working.
Check that the pipes are not obstructed (valve closed, basket or strainer full, etc.).
Check that the 4A fuse is not defective.
Changing the battery
Unplug the cables that are screwed to the "extension" circuit board.
Unscrew the "extension" circuit board.
Unscrew the black cover of the "main" circuit board.
Change the battery (CR2032 type).
Screw the black cover, the "extension" circuit board, and the cables back in place.
