What Is the Pentair Intellichlor IC40 Salt Cell?
The Intellichlor IC40 is a salt chlorine generator cell designed for in-ground pools up to 40,000 gallons. It converts salt into chlorine, helping maintain clean, clear water with less manual effort. From my experience, it’s a reliable system that integrates well with Pentair’s IntelliChlor controllers.
Why I Chose the IC40 Model
I picked the IC40 because my pool is around 30,000 gallons, so its capacity fit perfectly. The cell’s efficiency and durability were important to me since I wanted a low-maintenance option that lasts. The IC40’s design allows for consistent chlorine production without harsh chemicals.
Key Features That Stood Out to Me
- Self-Cleaning Technology: The cell has a reverse polarity feature that prevents scale build-up, which means less frequent manual cleaning.
- Easy Installation: I was able to install it myself with basic tools, thanks to clear instructions and compatible fittings.
- Energy Efficient: The IC40 uses less power compared to older models, which helped reduce my pool’s overall energy consumption.
- Durability: The titanium plates are corrosion-resistant, extending the lifespan of the cell in saltwater environments.
Considerations Before Buying
- Pool Size Compatibility: Make sure your pool size doesn’t exceed 40,000 gallons, or the cell won’t produce enough chlorine.
- Salt Level Requirements: The system requires maintaining a specific salt concentration (typically around 3,000 ppm), so you’ll need to monitor and adjust salt levels regularly.
- Replacement Costs: While the cell lasts several years, eventually, it will need replacement. Check current prices and warranty terms before purchasing.
- Controller Compatibility: The IC40 works best with Pentair IntelliChlor control systems, so ensure your setup supports it or be prepared to upgrade.
My Installation Tips
When I installed the IC40, I made sure to:
- Turn off the pool pump and power supply before starting.
- Mount the cell in the correct flow direction as indicated on the unit.
- Rinse the cell with fresh water occasionally to remove debris.
- Keep an eye on salt levels using a reliable salt tester to maintain optimal chlorine production.
Maintenance and Longevity
I found that routine maintenance is minimal. The self-cleaning feature really cuts down on scale issues. However, I still check the cell every few months for calcium buildup or debris and clean it as needed with a mild acid solution. Following this routine helped me keep the system running smoothly for over three years.
Final Thoughts
If you want a dependable salt cell that simplifies pool chlorination, the Pentair Intellichlor IC40 is a solid choice based on my experience.
