Use no sealing paste or compound. Tap connector not supplied; Siamp requires an approved check valve at the supply connection. Set the water level 20 mm below the overflow, mount the button with its nut and clip the cable case before replacing the lid. Use no limescale or chlorine cleaners in the cistern.\u003c\/p\u003e\n\u003c\/div\u003e\u003cp\u003eSpecification sheets: \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0858\/5268\/4624\/files\/file-optima50.pdf\"\u003eOptima 50 flush valve (PDF)\u003c\/a\u003e · \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0858\/5268\/4624\/files\/file-compact99b.pdf\"\u003eCompact 99B filling valve (PDF)\u003c\/a\u003e · \u003ca href=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0858\/5268\/4624\/files\/50_5531_00_LD.pdf\"\u003eInstallation manual (PDF)\u003c\/a\u003e · \u003ca href=\"\/collections\/toilet-cistern-parts\"\u003eSee related WC cistern parts\u003c\/a\u003e.\u003c\/p\u003e","brand":"Siamp","offers":[{"title":"Default Title","offer_id":53468754116944,"sku":"37998007","price":33.84,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0858\/5268\/4624\/files\/siamp-37998007-1024-crisp_113350b9-6a4f-4c4f-a4cd-d1f6a1717cf2.jpg?v=1787764875","url":"https:\/\/getplumb.co.uk\/products\/siamp-optima-50-and-99b-wc-flush-and-fill-component-pack","provider":"Getplumb","version":"1.0","type":"link"}
