It suits a professionally planned salt-system installation or replacement where the controller, cell, plumbing and electrical requirements have been checked. Match this exact model and SKU before ordering; pool volume, climate and chlorine demand all matter when selecting capacity.\u003c\/p\u003e\u003ch2\u003eBest For\u003c\/h2\u003e\u003cp\u003eOwners of permanently installed pools evaluating an InverCHLOR system in the up-to-40,000-gallon class.
