During normal operation a white calcium scale will build up on the plates of the electrolytic cell within your jandy aquapure ei salt generator. The cell operates most efficiently when the cell is clean so the manufacturer recommends checking your cell for scale monthly and cleaning the cell as required. This guide describes how to access and clean a Jandy AquaPure Ei cell.

Things You'll Need

Step by Step


Step 1

Check the scale buildup on your cell plates. This buildup will be visible without taking your cell apart. A little scale buildup is normal. If the buildup is excessive on the plates or debris has passed though the filter and collected in the cell, the cell must be cleaned.

Can also soak the chlorine generator cell in white vinegar overnight and it is far less harsh on your equipment. Actually works in just a few hours.

Kathy S - If you haven't had the ring off for a while, it may be corroded on. Squirt a little CLR over the nut and tap around the nut gently with the handle end of a screwdriver. Then use the locking ring tool to twist the not off counter-clockwise. If you don't have the locking ring tool, use a strap wrench.
