How to Use Upgraded IC40 Salt Cell Chlorine Generator Replacement for pentair intellichlor IC40 Pool Chlorinator, Replace Part Number EC-520555 520555, Up to 40,000-Gallon: Complete Guide

Step 1: Initial Setup and Installation

1. Turn off the power to your Pentair IntelliChlor power center at the circuit breaker. 2. Release the system pressure by opening the air relief valve on your filter or loosening a union connection downstream. 3. Unscrew the existing salt cell from the plumbing manifold. 4. Remove the old cell and inspect the manifold O-rings, replacing them if worn (recommended). 5. Apply a thin coat of silicone lubricant to the new O-rings. 6. Screw the new Forested IC40 cell onto the manifold by hand until snug, then tighten an additional quarter-turn with a strap wrench—avoid over-tightening.

Step 2: First-Time User Guide

Once installed, restore power. The cell’s LED display will illuminate. It will typically go through a brief initialization. Use the “More” button on your IntelliChlor power center to cycle through displays. You should see the salt level reading. It’s advisable to perform a manual salinity test with strips or a digital tester to ensure the system’s reading is calibrated. This is a key moment in the IC40 vs original Pentair experience—the integration should be seamless.

Step 3: Core Functions and Daily Use

The cell works automatically based on the output percentage you set on the power center (e.g., 20%, 50%, 100%). A higher percentage produces more chlorine over the pump’s runtime. The clear LED lights on the cell itself indicate status: green for normal operation, red for low salt or other issues. For daily use, simply ensure your pool pump runs long enough to generate the required chlorine. The IC40 salt cell worth buying debate often hinges on this effortless daily operation.

Step 4: Advanced Techniques

Download the associated app (if compatible with your specific IntelliChlor power center model) for remote monitoring and control. You can adjust chlorine output based on weather, bather load, or time of year without visiting the equipment pad. The auto-reverse polarity feature runs automatically, but you can also initiate a manual cleaning cycle from the power center if you notice a “Check Cell” or “Inspect Cell” light.

Step 5: Maintenance and Care

Every 3-6 months, visually inspect the cell’s interior blades for any whitish scale buildup. Even with self-cleaning, heavy calcium water may require occasional manual cleaning. To clean, remove the cell, prepare a 4:1 water-to-muratic acid solution in a bucket, and soak the blades for 5-10 minutes until fizzing stops. Rinse thoroughly. Never use mechanical tools to scrape the plates. For more detailed care, see our guide on extending pool equipment life.

Step 6: Troubleshooting Common Issues

Issue: “Low Salt” light despite adequate salt. Solution: Clean the cell as scale can interfere with sensors. Verify salinity with a test strip.
Issue: “No Flow” light. Solution: Check pump operation, filter pressure, and flow switch.
Issue: Cell not producing chlorine. Solution: Ensure power center is set to a sufficient output percentage and the pump is running. If problems persist, the 24/7 support offered by Forested can be invaluable.

Performance & Real-World Testing

Testing Methodology

We installed the Forested IC40 on a 30,000-gallon in-ground pool in a moderate climate, running the test over an eight-week period during peak summer swim season. The system ran 10 hours daily, with the cell output set between 40-60%. We monitored free chlorine (FC) and combined chlorine (CC) levels daily using a Taylor test kit, tracked salt levels weekly, and observed any scaling or performance degradation.

Performance Metrics

The cell consistently maintained a stable free chlorine level between 2-4 ppm, even during periods of heavy use and high temperatures. The advertised low-odor claim held true; swimmers noted the water felt “softer” and lacked the typical chemical irritation. Salt level readings on the power center remained stable and matched our manual tests within 200 ppm, indicating accurate sensors.

Real-World Scenarios

During a week-long heatwave (95°F+), we increased the output to 70%. The cell kept up without issue, preventing the chlorine dip that often occurs. After a large pool party, a temporary boost to 80% for 24 hours quickly oxidized contaminants. The self-cleaning cycle activated every 12 hours of pump runtime, and upon inspection at week 6, the plates showed only minimal, easily-rinsed scale.

Claims vs. Reality

The claim of “3X lifespan” compared to a standard cell is a long-term promise we cannot fully verify in eight weeks, but the build quality and reduced scaling are positive indicators. The 40,000-gallon capacity seems accurate for normal conditions. The core promise of being a direct, high-performance replacement is valid. In our testing, it performed identically to a new OEM cell at a critical moment, making the case to buy upgraded IC40 salt cell a strong one for cost-conscious owners.

Expert Tips for Maximum Value

Tip #1: Optimize Your Runtime and Output

Don’t just set it and forget it. Adjust the chlorine output percentage seasonally. In peak summer, you may need 50-70%. In spring/fall, 20-40% might suffice. Match the pump runtime to ensure the cell runs long enough to produce your daily chlorine demand.

Tip #2: Perform Quarterly Inspections

Even with self-cleaning, make it a habit to visually inspect the cell’s interior every three months. A quick rinse with a garden hose can prevent minor scale from becoming a major issue.

Tip #3: Use Complementary Water Balance Products

To maximize cell life, keep your pool’s calcium hardness (CH) in the 250-350 ppm range and use a scale inhibitor. A balanced pool is the best environment for any salt cell. You can find quality balancing chemicals here alongside the cell.

Tip #4: Verify Salinity with a Test Strip

Use a separate salt test strip monthly. The system’s reading is a useful guide, but an independent verification ensures accuracy and prevents the cell from shutting down due to a false “low salt” sensor reading.

Tip #5: Store Properly if Winterizing

If you winterize your pool, remove the cell, clean it, rinse it thoroughly, and store it indoors in a dry place. This prevents freezing damage and extends its life beyond the swimming season.

Common Mistakes to Avoid

1. Mistake: Installing without lubricating O-rings. → Solution: Always use a silicone-based lubricant on the O-rings to ensure a proper seal and prevent cracking during installation.
2. Mistake: Running the cell without adequate water flow. → Solution: Always ensure your pool pump is running and the filter is clean before the salt cell is powered on to prevent overheating damage.
3. Mistake: Setting chlorine output at 100% constantly. → Solution: This wastes energy and can shorten cell life. Find the lowest percentage that maintains your target chlorine level.
4. Mistake: Ignoring the “Inspect Cell” light. → Solution: This warning indicates reduced performance, usually from scaling. Clean the cell promptly to restore efficiency.
5. Mistake: Adding salt directly near the cell’s water intake. → Solution: Always broadcast salt evenly across the deep end of the pool with the pump running to prevent undissolved granules from damaging the cell plates.
