The treatment should be dosed at 25 litres per 100 litres of system capacity (25%) to achieve the NSF CIAS performance standard, with additional antifreeze available if further freeze protection is required. The product can be introduced into the system through a filling loop, drained radiator, powered flushing machine, or Feed \u0026amp; Expansion tank, after which the circulation pump should be run to distribute the solution evenly throughout the system. For best results the antifreeze should be diluted with demineralised, softened, or mains water, and systems treated with antifreeze should be drained and refilled every five years to maintain effective protection.\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003e \u003c\/li\u003e\n\u003cli\u003e \u003c\/li\u003e\n\u003cli\u003e \u003c\/li\u003e\n\u003cli\u003e \u003c\/li\u003e\n\u003cli\u003e \u003c\/li\u003e\n\u003cli\u003e \u003c\/li\u003e\n\u003cli\u003e \u003c\/li\u003e\n\u003cli\u003e \u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e* See Technical Attachments for more precise details and parameters.\u003c\/p\u003e","brand":"Scalemaster","offers":[{"title":"Default Title","offer_id":53748846461274,"sku":"H001532","price":50.75,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0844\/4657\/6986\/files\/508009_-_Copy.gif?v=1772808269"}],"url":"https:\/\/www.oceanairuk.com\/collections\/scalemaster.oembed","provider":"Oceanair","version":"1.0","type":"link"}
