ASSEMBLY

➤ Precompression for the initial installation is achieved by a band  placed round the outside (our

flexible elements are delivered with this band).

➤Position the flexible element with its band to attach three non-adjacent holes to the three arms of

one flange, and then the three other holes to the other flange.

➤Tighten the bolts to the following torques :

Cut the original band or remove the disassembly band.
