The power pack has an automatic cell cleaning feature (polarity reversing) that removes scale deposits from the cell
(seeSection5.6).

signs of scale.
If the cell has a tendency to scale, it is recommended that every month the cell be removed and inspected for scale
formationand/ordebris.Someltersallowdebristopassthroughtothecellwhichcouldlodgebetweentheplates
in the cell. A small amount of scale formation is normal. If by looking through the cell it is observed that there is
excessivescaleformationbetweentheplatesordebrisispresent,thecellmustbecleanedasfollows:
1. Ensure that all power to the power pack and the controller is disconnected/turned off at the circuit breaker.
