77 V 1 1 2 2 3 5 V PRE-ASSEMBLED TIGHTENING INDICATORS FOR Ø 16.5 Ø 25 Ø 40 CONNECTORS There are important visual markings on the bodies and nuts of Transair ® Ø16.5, Ø25 and Ø40 connectors. These are represented by solid and empty arrows and indicate the opti- mum torque. When assembling Transair ® connectors, the nuts are tightened to a pre-defined torque on the body of the connector. This torque guarantees the seal and safety of each connection. Before using Ø16.5, Ø25 or Ø40 connectors, ensure that these arrow marks are correctly aligned with each other. There is no need to loosen the nuts prior to joining Ø16.5, Ø25 and Ø40 connectors to Transair ® aluminium pipe. Do not exchange the nuts. Do not use a nut on another connector. Installation Guide
