Salt Cell Maintenance
Proper salt cell maintenance keeps your Pentair Intellichlor IC40 running smoothly. The salt cell creates chlorine by converting salt in the water. Dirt, scale, and wear can reduce its efficiency. Regular care helps avoid costly repairs and extends the cell’s life.
Check the salt cell often for build-up or damage. Simple cleaning and timely replacement make a big difference. Follow these steps to maintain your salt cell effectively.
Cleaning The Salt Cell
Turn off the system before cleaning the salt cell. Remove the cell carefully from the pool’s plumbing. Rinse it with fresh water to remove loose debris.
Soak the cell in a mild acid solution to dissolve calcium build-up. Use a mixture of one part muriatic acid to ten parts water. Soak for about 10 to 15 minutes. Rinse thoroughly with water after soaking.
Never use sharp tools to scrape the cell plates. This can damage the metal plates inside. Clean the cell every 3 to 6 months for best results.
Signs Of Cell Wear Or Failure
Low chlorine production is a common sign of cell wear. Check for error codes on the Intellichlor display. Visible cracks or corrosion on the cell plates indicate damage.
Scale build-up that won’t clean off signals a worn-out cell. The system may shut down if the cell fails completely. Watch for changes in chlorine levels or flow indicators.
Regular inspections help spot problems early. Replace the cell to keep your pool safe and clean.
Replacing The Salt Cell
Turn off power and water flow before removing the old salt cell. Disconnect the cell from the plumbing and wiring carefully. Avoid pulling on wires to prevent damage.
