We just bought our house about a month ago and the current setup has a Resilience A5 salt cell. While messing with the control box I noticed the chlorine output percentage wouldn't go pass 10%. Called American SPS (makers of cell) and they instructed me to open it up and inspect the blades to see if any (most likely middle blade) were shorter or thinner than the others. So I pulled it off and sure enough, the middle blade and one of the outside blades were shorter than the other three and the middle blade had a lot of greenish/white buildup on it. Afterwards I went ahead and ordered a factory replacement exactly like the original one. When I got it in and opened it up, I noticed on the cell that it had an arrow with the words "flow direction" pointing AWAY from the large blue end. I had to go back and look several times to make sure I wasn't wrong, but the current setup appears to have the salt cell on BACKWARDS! The red arrow is the flow of my return water going through the cell and currently it's going TOWARDS the large blue end (opposite of what the "flow direction" indicates). Am I missing something here? First pic shows my salt cell in the current setup, second pic shows the new salt cell I ordered with the flow direction arrow.
