Installation notes
1. Before installation, loosen the pressure-plate bolts and extend the joint to the installation length shown in the table. Tighten the bolts diagonally and keep the pressure plate aligned.
2. Install the expansion joint in a straight pipe section between two fixed supports. Provide guide supports and stops to allow normal movement and prevent separation.
