How should a new commercial oven be inspected on arrival?

Please verify the following points and require itemized written supplier responses:（commercial oven oven-acceptance） Verify model, energy type, nameplate, trays, manuals, warranty and appearance, then test heating, temperature control, fans and seals. Contact the supplier before using units with deformation, missing parts, gas leaks or electrical odors. Define capacity, accuracy, materials and operating environment before requesting quotes on a uniform basis. Request specification sheets, test reports, certificates, maintenance manuals and spare-part lists. During acceptance, verify appearance, dimensions, functions, safety protection and packaging, and keep test records.
