Specifications

Installation Information

Disconnect all electrical power to the automation load center and connected pool equipment before opening the enclosure or servicing the SCG electrical components.

Before removing the existing 521218 board, document all electrical connections and inspect the IntelliChlor transformer, SCG circuit breaker, power cable, connectors, and surrounding wiring for signs of overheating, corrosion, or damage.

Because the board is installed inside an enclosure containing line-voltage electrical equipment, replacement should be performed by a qualified pool automation professional or licensed electrician.

Confirm Before Ordering

Pentair 521218 is specifically identified as:

• New Load Center IntelliChlor SCG Surge Board PCBA
• IntelliChlor salt chlorination power-system component
• Compatible with applicable newer EasyTouch load centers
• Compatible with applicable IntelliTouch load centers
• Listed for EasyTouch PL4 / PSL4 applications

Pentair identifies 521218 as the after-change-date IntelliChlor circuit board for applicable EasyTouch systems. Older systems may use 520723, so the existing board part number and load-center generation should be confirmed before ordering.

IntelliCenter Compatibility

For a factory IntelliCenter load center, confirm the existing SCG circuit-board part number before ordering. The 521218 is primarily documented for EasyTouch and IntelliTouch load centers.

Certain systems upgraded from EasyTouch or IntelliTouch to IntelliCenter may retain the original compatible load-center hardware, so compatibility should be determined by the installed load center and existing board rather than the automation software platform alone.

Warranty Information

The Pentair 521218 is currently listed with a 1-year general warranty. Warranty eligibility and coverage may depend on installation, purchase channel, proof of purchase, and current Pentair warranty requirements.
