- Carry out a calibration of the pH probe (see chapter 12.1).
- Check the salt levels in the pool using a testing kit.
- Top up the salt, if necessary, so as to achieve a salt content of 5 kg/m
- Check that the pipe at the level of the accessories holder is completely
filled with water.
- If necessary, top up the water in the pool.

- the valves on the filtration heat contactor are open.
- the filtration pump is working correctly.
- the filtration heat contactor is not blocked.
- there is enough water in the pool.
- Check that scale deposits have not built up on the cell (to remove scale,
see chapter 14.2).
- Check and adjust, if necessary, the current inversion frequency powering
the cell (see the "

- Check that the electrical connections to the terminals of the cell are
sufficiently tight and not oxidised.
- Check that the cell's power cable is in a good condition.
- Check that the cell's power cable connector is correctly connected to the
electronics unit.
- As a last resort, replace the cell.
