An OEM solar thermal file should include at least <strong>8 controlled document groups<\/strong>.<\/p>\n<p>2. Drawings need <strong>revision codes<\/strong> before production.<\/p>\n<p>3. <strong>Inspection records must match the shipped model<\/strong> \u2014 not a generic datasheet.<\/p>\n<p>4. <strong>Packaging data<\/strong> should support import + warehouse planning.<\/p>\n<p>5. The <strong>warranty boundary<\/strong> should name pressure, water quality, freeze risk, installation method, and service intervals.<\/p>\n<\/blockquote>\n<p>SOLETKS explains custom solar thermal scope through its <a href=\"https:\/\/service.soletksolar.com\/custom-engineered-solar-thermal-products\/\">custom engineered solar thermal products<\/a> guidance and frames factory documentation through the <a href=\"https:\/\/service.soletksolar.com\/company\/quality-assurance\/\">SOLETKS quality assurance<\/a> page.<sup>[1]<\/sup><\/p>\n<hr>\n<\/section>\n<section id=\"1-the-soletks-6-step-quality-workflow\">\n<h2>1.

They usually include datasheets, GA + interface drawings, BOM summaries, inspection records, packing lists, installation guides, warranties, and commissioning forms \u2014 at least <strong>8 document groups<\/strong>.<\/p>\n<h3 id=\"why-are-drawings-important-for-oem-solar-thermal-products\">Why are drawings important for OEM solar thermal products?<\/h3>\n<p>Drawings define <strong>dimensions, ports, mounting points, hydraulic interfaces, airflow boundaries, wiring, and service access<\/strong>. Without an approved drawing revision, the factory, buyer, installer, and service team may use different assumptions \u2014 leading to fit errors and warranty disputes.<\/p>\n<h3 id=\"how-many-documents-should-an-oem-buyer-request\">How many documents should an OEM buyer request?<\/h3>\n<p><strong>Start with at least 8 document groups<\/strong>: datasheet, general arrangement drawing, interface drawing, BOM summary, inspection record, packing list, installation guide, and commissioning form. More files needed when the order includes private label, PVT electrical data, control panels, local certificates, or multilingual packaging.<\/p>\n<h3 id=\"what-is-soletks-6-step-quality-workflow\">What is SOLETKS&#8217; 6-step quality workflow?<\/h3>\n<p><strong>Procurement \u2192 Design \u2192 Manufacturing \u2192 Integration \u2192 Testing \u2192 Delivery<\/strong> \u2014 with <strong>160+ in-process inspection steps<\/strong> across this chain.
