Compatibility Notes
This IC40 salt cell is intended for compatible Pentair IntelliChlor systems. It should not be selected only by appearance, because plumbing unions, power center compatibility, cell model, and system setup must match before replacement.
If your system needs the control box or power supply instead of the cell, compare the Pentair 520556 IntelliChlor power center before purchasing. If your pool size or system setup is different, also compare the Pentair 520554 IntelliChlor IC20 salt chlorine generator cell or the Pentair 521105 IntelliChlor IC60 salt chlorine generator cell.
Salt Cell Function and Operation
The IC40 cell helps produce chlorine from dissolved salt as pool water passes through the cell. Proper water flow, salt level, stabilizer level, and balanced pool chemistry are required for consistent performance.
The system may help reduce the need for manually adding chlorine tablets, but it does not remove the need for water testing. Pool owners should still check free chlorine, pH, alkalinity, stabilizer, calcium hardness, and salt level on a regular schedule.
Installation Guidance
Before installing this cell, turn off all pool equipment power and follow the Pentair installation manual. Confirm the correct water flow direction, union fit, wiring connection, bonding requirements, and system startup steps.
If you are replacing an old salt cell, review a salt cell replacement guide before removing the existing cell. Make sure the old cell issue is not caused by low salt, high salt, poor flow, dirty filters, damaged wiring, or a failed power center.
Cell Cleaning and Maintenance
Inspect the IC40 cell during the pool season for scale buildup, debris, or low-flow issues. Clean the cell only when needed and only according to the manufacturer’s instructions.
Avoid scraping the cell plates or using harsh cleaning methods. If approved acid-wash maintenance is required, compare the IntelliChlor acid washing kit before reinstalling the cell.
Before Ordering
Before buying, confirm that this is the correct IC40 replacement cell for your pool system. Buyers comparing an aftermarket option can also review the IC40 pool salt cell replacement to check fit, model references, and package details before deciding.
