Poor quality, great when it works
After 1 year it stopped working. The problem was a bad flow meter, which I was able to replace myself, but if you look around you will see this is a common problem. I had my pool installed 2 years ago with the following pentair components: pump, chlorinator, control panel, LED Light. The only component that has not failed is the pump. The control panel was covered by warranty. I am going to live without the light as the cost to replace is not worth the expected lifespan. These chlorinator have a 60 day warranty! Dont fall for this poorly engineered garbage

Q: I have an ic 40 520555 and am showing no green or red lights when my system is turned on. Do i need to replace the generator or just the cell? both are going on their 3rd summer. Thanks

Asked by: Scott - 5/7/2018
A: I would recommend checking the fuse underneath the power center. If that doesn't fix it, it could be a more serious electronics problem. But even if it's not the cell, I would give you a heads up that based on my experience, three years is fairly deep into that system's cell lifespan, just so you can make a better decision about what you want to do.

Q: All 4 or 5 green lights in a row are flashing. What does that mean?

Asked by: Bobey - 12/14/2020
A: This is a feature for low chlorine. The Output Levels are listed as 20%, 40%, 60%, 80%, and 100%. Since in the winter some people will prefer to have less than 20%, if you press the LESS button when 20% is selected, it will take you to the Low Chlorine Output mode. This changes the lights to 2%, 4%, 6%, 8%, and 10%. You will know this by the lights flashing instead of staying solid. If you have all 5 lights flashing, you are currently in Low Chlorine Output Mode and it is set to 10% output. To leave this setting, you just need to increase output and it will go back to the original 20-100% mode.

Designed for Outdoor Installation and Operation
The Pentair IntelliChlor controls are built-in to the electrolytic cell. It has LED indicator lights that display low or high measured salt levels, five sanitizer output power levels, and whether the cell requires checking or service. The controls also have a built-in mechanical flow switch that ensure sufficient water flow for chlorine generation. Under low water temperature conditions, the IntelliChlor control's automatic shut-off feature protects the unit and prolongs cell life. In addition to the cell's built-in controls, there is a metal power supply box that is included with the Pentair IntelliChlor which is meant to hang nearby on the wall, with a UL Listed internal transformer which supplies power to the cell through a 15' UL Listed cable. The power supply box gets connected to your pool equipment power source or timer.
The Pentair IntelliChlor electrolytic cell is an inline opaque-plastic housing which contains built-in titanium electrode plates, built-in electronic controls, built-in flow switch, and built-in power supply cord. The IntelliChlor salt cell has threaded connections on the inlet and outlet, which allows quick access for service or winter removal (if applicable). The threaded connections attach to 2" unions which are glued to the existing return-line PVC plumbing.
