Pickup currently unavailable at ePoolSupply - Chandler AZ
Pentair EC-520555 is the IntelliChlor IC40 salt chlorine generator cell; its required power center is sold separately. It converts dissolved pool salt into chlorine while the circulation system is running.
Brand: Pentair; Part number: EC-520555; Model: IC40; Nominal pool capacity: Up to 40,000 US gallons; size for actual chlorine demand; Rated chlorine production: 1.40 lb per 24 hours of operation; Power equipment: Compatible power center required; sold separately; Water care: Salt chlorination; routine sanitizer and water-balance testing required
Does it include a power supply? No. This is the cell listing. A compatible IntelliChlor power center, such as EC-520556, is required separately unless the existing installation already provides the correct power connection. What size pool can it serve? Pentair rates IC40 for pools up to 40,000 gallons. This is a nominal maximum, not a promise for every installation. Heat, sunlight, swimmer load and operating hours affect the required chlorine output. Does a salt pool still contain chlorine? Yes. The cell produces chlorine from salt. Continue testing sanitizer, pH and other water-balance parameters; the cell does not measure free chlorine or replace water-care work. Is it maintenance-free? No. Automatic polarity reversal helps reduce scale, but the cell still needs inspection and cleaning when indicated. Follow the manual rather than applying a fixed acid-cleaning schedule. Can I replace a different IntelliChlor model with this one? Confirm the required output, existing plumbing and power equipment first. Match the model and installation guide before ordering; a similar product name alone does not establish compatibility.

Pentair IntelliChlor IC40 Salt Chlorine Generator | EC-520555
Pentair EC-520555 is the IntelliChlor IC40 salt chlorine generator cell; its required power center is sold separately. It converts dissolved pool salt into chlorine while the circulation system is running.
Sizing for your pool
Start with pool volume, then consider daily chlorine demand and the time available for circulation. A cell operated for only part of the day cannot produce its full 24-hour rating. Have your pool professional confirm whether IC40 provides enough capacity during peak swimming weather.
Controls and daily operation
Cell-mounted indicators help you check operating status, and output controls let you adjust production as pool demand changes. Flow, temperature and salt conditions can affect operation. Investigate an alert using the troubleshooting section before increasing output or replacing equipment.
Installation and ownership
Have a qualified professional check the cell location, circulation flow, electrical supply and automation connection. Chlorinator power must be coordinated with the filter pump so the cell cannot operate without water circulation. Select the power center separately if one is not already installed.
