So I just purchased a replacement IC40 cell. My previous cell died in 2011, and I've been using tablets for the last two seasons.
The replacement cell is working nicely so far. My only gripe is that Pentair apparently changed the orientation of the control panel relative to the flow direction. As a result, when the cell is installed, the control panel is upside down.
This is not a huge deal, but I was wondering if it is possible to detach the panel and reinstall it in the opposite orientation.
