Pentair IntelliChlor System Transformer | EasyTouch Control System | 520722

Description

The Pentair IntelliChlor System Transformer (520722) is the OEM replacement transformer for EasyTouch Control Systems paired with IntelliChlor salt chlorine generators — specifically for units manufactured before the 2011 change date.

⚠️ IMPORTANT: PRE-2011 UNITS ONLY — VERIFY YOUR CHANGE DATE BEFORE ORDERING
This transformer is designed for EasyTouch Control Systems manufactured before the 2011 change date. If your system was manufactured on or after that date, this part may not be correct for your installation. Check the date code or revision label on your existing transformer before ordering.

⚠️ IMPORTANT: HIGH-VOLTAGE ELECTRICAL COMPONENT — PROFESSIONAL INSTALLATION REQUIRED
Electrical control components must be installed or replaced by a qualified electrician or certified pool technician.

The transformer steps down incoming line voltage to the operating voltage required by the IntelliChlor salt chlorine generation system within the EasyTouch control platform. A failed transformer will prevent the IntelliChlor cell from receiving power, halting chlorine production entirely. Replacing a faulty transformer restores normal automated sanitizer output without requiring replacement of the full control system.

Specifications

Fits Into

Compatibility is based on Pentair parts documentation and available OEM records. This is not an exhaustive list. For certainty, verify the part number in your equipment’s manual or on the original part itself before ordering.

Pro Tip

Before ordering, locate the date code or revision label on your existing transformer. This part applies only to EasyTouch systems built before the 2011 change date — systems produced after that date use a different transformer. If the label on your unit is worn or missing, cross-reference the part number printed on the transformer body itself against 520722 to confirm fitment.
