Any mechanical rework to couplings that are used in hazardous areas require an explicit release by KTR. The orderer must send a drawing to KTR acc. to which the manufacture must be made. KTR checks this drawing and returns it to the orderer with approval. - Page 8 Z 390312 Z 391674 Z 391668 Z 391671 Z 391670 Z 391675 Z 390408 Z 391672 Z 388611 Z 388610 Z 391669 Z 391673 Gezeichnet: 23.05.12Kb Ersatz für: KTR-N vom 26.03.09 Schutzvermerk ISO 16016 beachten.
