Pentair has made some significant design changes to the IntelliChlor Salt Cell. In my opinion they’ve simplified the front control panel although the verdict is out as to technical changes that have been released.
I’ve been seeking a HOW TO calibrate the IntelliChlor and my sources at Pentair provided this Field Calibration Guide. Of course, I thought it would be helpful to pass along to our readers.
Apparently this calibration is only applicable to older models as the newer models “do not require calibration”. This last statement will require further confirmation. The following calibration
guide is intended for older units that fall below Version 1.9. To determine the version of your IntelliChlor Salt Cell flip the cell over and look for the label stamped with a bar code. Look to the bottom left corner of that sticker to identify the version number (see picture). Chances are the sticker may have fallen off over the course of time.
Here’s another trick I’ve found. The newer units being produced have version numbers starting at 3.0 and greater. The face of the newer units are distinctly different. (a) The unit to the LEFT is the older unit and has the words “Check Salt” in the first box of the display. They’ve removed this in the new units. (b) The LEFT unit has “Pwr” or Power and “Life” where the unit to the RIGHT has replaced these two indicators with “Cold Water”.
The steps mentioned below provide a method to calibrate or reset to factory presets. The key to calibration is making sure that your water is FIRST chemically balanced and SECOND salt levels have been confirmed. If your system is still not operating properly, calibration is the next step prior to replacing the unit altogether. See steps below:
