Pentair 521171 IC15 External Power Supply

Over time, the external power supply for your Pentair IntelliChlor system can be susceptible to failure from various environmental factors. Power surges, often caused by lightning strikes or fluctuations in your home's electrical grid, can damage internal components. Additionally, exposure to moisture or corrosion, especially in the humid environment around a pool, can degrade connections and circuitry. As the unit ages, the components within the power supply naturally wear out, reducing its efficiency and eventually leading to complete failure. If the IC15 External Power Supply fails, the most immediate consequence is that your IntelliChlor system will stop producing chlorine. This means your pool will no longer be sanitized, leading to cloudy water, algae growth, and potentially unsafe swimming conditions. Without a functioning power supply, the entire salt chlorine generation process halts, and you'll likely need to resort to manual chlorine additions to maintain water quality. Replacing the power supply is essential to restore your IntelliChlor system's automatic sanitization capabilities and prevent further issues with your pool water chemistry.
