Step 1. Follow the preliminary set-up steps of the Grooved Pipe and Gasket Preparation section on pages 16 and 17. Failure to follow these preliminary set-up steps before product installation can adversely affect subsequent system performance.
Step 2. Install the gasket by placing it over the pipe so that the gasket lip does not extend beyond the end of the pipe. Bring both pipe ends together ensuring vertical and horizontal alignment. Slide the gasket into position cen- tering it between the grooves of each pipe end.
Step 3. With one nut and bolt removed, “swing” the coupling housing over the gasket. Verify that the housings are over the gasket and that the housing keys are fully engaged into the grooves.
