Description
The Pentair 357521Z IntelliFlo VSF Drive Kit is a complete replacement kit for the drive electronics and keypad used in IntelliFlo XF and IntelliPro XF VSF pumps manufactured after August 2015. It packages the drive control board, housing, and user keypad control into one unit, enabling speed selection, diagnostics, and whole variable speed operation once again. Designed per Pentair’s OEM mechanical and electrical standards, this kit simplifies installation and minimizes downtime.
Pro Tip
Take note of your previous speed and timer settings before removal; those can be reprogrammed into the new drive. Use fresh screws and gaskets to ensure a watertight seal. Verify that the wiring harness connectors are securely seated before powering up.

Installation Tips
Disconnect all power before servicing. Remove the old drive by loosening the three internal drive-to-motor screws. Carefully lift the drive out, align the new unit, and secure it using the same mounting points. Confirm that the keypad housing is sealed and the wiring is correctly connected. Refer to Pentair’s official drive replacement instruction manual.
