The manufacture date is typically printed on the heater's rating label inside the front access panel. If the original harness is still partially intact, photograph the connector layout and routing path before removal; this reference will assist your technician during installation and ensure the replacement is routed identically to the factory configuration.\u003c\/p\u003e\n\n\u003c!-- wft:processed:manual:2026-04-06 --\u003e","brand":"Pentair","offers":[{"title":"Default Title","offer_id":53971917308179,"sku":"461107","price":349.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0920\/0687\/5411\/files\/pentair-heater-wiring-harness-115-230v-mastertemp-max-e-therm-461107.webp?v=1776370315","url":"https:\/\/poolaroo.com\/products\/pentairwaterpoolandspainc_461107","provider":"Poolaroo","version":"1.0","type":"link"}
