The change was driven by the salt cell moving from IntelliChlor IC40 to the newer IntelliChlor Plus40 (523735). The system ships in an \u003cstrong\u003eIntelliCenter Load Center\u003c\/strong\u003e with a 150 A built-in circuit breaker subpanel and five pre-installed high-voltage relays. Both the \u003cstrong\u003esalt chlorine generator transformer\u003c\/strong\u003e and a salt cell are included, along with two \u003cstrong\u003eIntelliValve valve actuators\u003c\/strong\u003e for the intake and return diverters.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eA note on the cell.\u003c\/strong\u003e Pentair's documentation is not fully consistent. The Pentair SKU page, the replacement-parts sheet and the Automation Transition document all describe 521906 as shipping the \u003cstrong\u003eIntelliChlor IC40\u003c\/strong\u003e, while the Transition Guide's cell column reads “Yes, ICL Plus40” — a column that most plausibly describes the replacement part number rather than the legacy one. We list IC40 on the strength of the three SKU-specific sources and recommend confirming with your distributor before ordering.
