5.5 Polarity Reversal

The Jandy AquaPure Ei chlorine generating device is a reversable polarity cell which means that for every fi ve (5)
hours of operation the cell will switch its polarity to help prevent any build up of calcium on the cell plates. This is
sometimes referred to as the automated cell cleaning feature. During the transition between changing its polarity there
is a fi ve (5) minute wait time when the cell will not produce any chlorine. Once it has changed polarity it will continue
to make chlorine.
NOTE 'CLEANING' will be displayed on the screen during the fi ve (5) minute 'WAIT' period. The output
level indicator will remain as set during the cleaning period.

5.6 Backup Battery

connected. In the event of a power failure the battery will retain ALL settings.
In the event of the battery losing its charge, the microprocessor in the unit will retain the following settings
permanently:
• Operating hours
