The complete-fit checklist DAYWELL ORIGINAL — DRAFT v0.1 — 2 November 2026 PRIVATE PROTOTYPE / NOT APPROVED INSTALLATION INSTRUCTIONS Record more than nominal tube diameter before selecting an adapter. Six checks Record the motor body/head revision, output geometry and retention, crown interface, exact tube cross-section, mounting bracket and intended application/load. Evidence levels Unknown means no supporting evidence. Supplier-claimed means a vendor assertion. Documented means literature supports the specific statement. Physically verified requires a recorded actual test. None implies every load or generation works. Before ordering Only an approved exact mapping can produce an automatic adapter recommendation. Select motor and adapter quantities separately. An unsupported profile needs a fit-check; keep its measurements and photographs with your account request.
