Translated from the supplied original catalogue, PDF page 13. Certificate reference: CCRI 22.7257. The original source files remain unchanged and are preserved separately. No official seal or signature has been recreated.
The original contains a handwritten approval signature, a manufacturer seal and an issuing-organization seal. The handwritten signatory name and some overprinted issuer-seal details are not reliably legible. No signature, seal, logo or QR code is recreated in this unofficial translation.
- The associated-apparatus model appears to read KDW127/12. The W is not fully resolved at the original image resolution; confirm against a higher-resolution original or the issuer record. Do not use this apparent reading alone to select associated apparatus.
- The handwritten approval signatory name is not reliably legible.
- The issuer seal contains additional small purpose wording and a numeric registration string, partly obscured by black text and a horizontal rule; these are not reliably transcribed or reconstructed.
- Company, issuer and parenthetical center English names are descriptive renderings; official registered English names have not been verified.
Each certificate applies to the named model and its stated scope, not the complete CHILL product range. Confirm the original and current status before procurement.
