5.2.11 Setti ng the durati on of polarity reversal
The principle of polarity reversal is to eliminate the scaling that builds up on the electrodes by reversing the electrical
current for a set length of ti me. By default, the cycle reverses
every fi ve hours.
Depending on locati on, water will be more or less hard (water hardness = TH).
To preserve the electrodes from scaling (which reduces the eff ecti veness of the electrolysis reacti on), the polarity
reversal ti me can be changed.
• Before setti ng the polarity reversal ti me, analyse the hardness of the pool’s water (TH), see «4.1 I Water
balance»
.

During reversal, chlorinati on is stopped for a few minutes. No message is displayed on the screen.
Normal operati on will resume aft er the reversal.
