Is this the right part?\u003c\/h3\u003e\n\u003cp\u003eYes. This is a common source of confusion — the box is labelled \u003cstrong\u003e521218\u003c\/strong\u003e while the board itself is printed \u003cstrong\u003e521593\u003c\/strong\u003e. They are the same component.\u003c\/p\u003e\n\n\u003ch3\u003eWill this work in an IntelliCenter?\u003c\/h3\u003e\n\u003cp\u003eThe surge card used in IntelliCenter, EasyTouch and IntelliTouch load centers is functionally the same and generally interchangeable. Do not confuse it with the surge card in the standalone IntelliChlor Power Center, which is a different shape and size.\u003c\/p\u003e\n\n\u003ch3\u003eWhat are the symptoms of a failing surge board?\u003c\/h3\u003e\n\u003cp\u003eTypical signs are the salt cell not generating, intermittent chlorinator operation, or visible yellowing and heat discolouration around the transformer feed on the board.\u003c\/p\u003e\n\n\u003ch3\u003eShould I check anything else at the same time?\u003c\/h3\u003e\n\u003cp\u003eYes. A surge board that has overheated has often been affected by a failing transformer. Inspect the load center transformer while the panel is open.\u003c\/p\u003e\n\n\u003ch3\u003eWho should install it?\u003c\/h3\u003e\n\u003cp\u003eA qualified pool technician or licensed electrician. The load center carries line voltage and must be isolated before the door is opened.\u003c\/p\u003e\n\u003cdiv class=\"ps4u-faq\"\u003e\n\u003ch2\u003eFrequently asked questions\u003c\/h2\u003e\n\u003ch3\u003eHow many gallons is this salt system rated for?\u003c\/h3\u003e\n\u003cp\u003eThe gallon rating is part of the model designation and is listed in the specification section above. Sizing up is normal practice: a cell rated above your pool volume runs fewer hours to hold the same chlorine level and generally lasts longer than one running at its limit.\u003c\/p\u003e\n\u003ch3\u003eWhat is the part number for this salt cell?\u003c\/h3\u003e\n\u003cp\u003ePentair lists this salt cell under part number 521218. Quote 521218 when you cross-reference against your equipment manual, an existing part, or a parts diagram, so you are comparing the same revision.\u003c\/p\u003e\n\u003ch3\u003eHow long does a salt chlorinator cell last?\u003c\/h3\u003e\n\u003cp\u003eCell life is measured in operating hours rather than calendar years, and most residential cells give several seasons of service. Life is shortened by high cyanuric acid, low water temperature operation, scale buildup on the plates, and running the cell at a high output percentage for long periods.\u003c\/p\u003e\n\u003ch3\u003eHow do I confirm this fits my equipment?\u003c\/h3\u003e\n\u003cp\u003eMatch the part number stamped on the component you are replacing, or look it up in the parts list for your Pentair equipment. If your model or serial number is not named on this page, send it to us before you order and we will confirm the fit.\u003c\/p\u003e\n\u003ch3\u003eDo I need a matching power supply or control unit?\u003c\/h3\u003e\n\u003cp\u003eA cell and its power centre are matched as a pair; a cell will not generate chlorine on a power supply it was not designed for. Check whether this listing is the cell only, the power supply only, or a complete system before ordering.\u003c\/p\u003e\n\u003ch3\u003eIs there a warranty on this salt cell?\u003c\/h3\u003e\n\u003cp\u003eIt carries the standard Pentair manufacturer warranty. The terms are set by Pentair, and on some equipment the coverage only applies when a licensed professional performs the installation. Keep the receipt and packaging until you have confirmed correct operation.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":52911968780605,"sku":"521218","price":229.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0968\/6741\/8429\/files\/OIP_9_3d88c98c-e038-4a9a-8390-9a2caddc2fe7.webp?v=1787343847","url":"https:\/\/poolsupply4u.com\/products\/pentair-521218-load-center-intellichlor-scg-surge-board-pcba-easytouch-intellitouch-genuine-oem","provider":"PoolSupply 4U","version":"1.0","type":"link"}
