IC40 Cell Compatibility
The IC40 cell should be matched with a compatible Pentair IntelliChlor system before purchase. If you do not already have the correct power setup, review the Pentair IntelliChlor power center before ordering this replacement cell.
For broader replacement guidance, compare this product with our replacement salt cells guide before choosing a new cell for your pool system.
Cell Only – Power Center Required
This product does not replace the power center or automation controller. If your system is not powering on, showing errors, or failing to communicate with the cell, check the power center, wiring, fuse, flow, and controller before replacing the cell.
If you are working with a smaller Pentair setup, compare this item with the Pentair IntelliChlor IC20 salt chlorine generator cell before choosing the correct size.
Choosing the Right IntelliChlor Cell Size
The IC40 is commonly used for larger residential pool setups, but the correct cell size depends on pool volume, pump run time, climate, swimmer load, sunlight, and water balance. Avoid choosing a cell only by model name; confirm the recommended pool-size rating before purchase.
For larger pool needs, compare this product with the Pentair IntelliChlor IC60 salt chlorine generator cell before deciding which model fits your system.
Installation and Maintenance Notes
Install the cell according to the Pentair manual and make sure the flow direction, unions, cable connection, and plumbing position are correct. After installation, test salt level, chlorine, pH, alkalinity, stabilizer, calcium hardness, and water flow regularly.
For cleaning and scale control, check the Pentair IntelliChlor acid washing kit before using any cleaning method on the cell.
What to Check Before Buying
Before purchase, confirm the exact model number, US version, compatible power center, included parts, warranty, return policy, and product image accuracy. Also verify whether unions, O-rings, cable, manual, or installation parts are included or sold separately.
