Installing Grommets <br /> Select the proper size hole saw for the Uniseal Grommet to be installed. Cut <br /> a hole in the Sump/Riser wall at the pipe or conduit exit point. Next insert _ <br /> the appropriate Uniseal Grommet into the opening with the flange on the <br /> outside of the Sump/Riser wall, as illustrated. <br /> i <br /> Inserting Pipe <br /> Before inserting the pipe or conduit into the pre-installed grommet <br /> it would be helpful if the pipe edge was tapered. To ease pipe _ <br /> insertion through the grommet, soaping the pipe first, with liquid <br /> soap, is recommended. Push the pipe or conduit through the <br /> grommet as far as required. The tapered I.D. of the Uniseal Grommet <br /> expands its O.D. which seals and locks it into the Sump/Riser wall. <br /> Contained Pipe Exits <br /> When exiting the Sump/Riser with the secondary containment pipe use <br /> either the A cr B Uniseal Grommet. Use the A Grommet for sealing the = <br /> Telescoping A°Straight Pipe, used for 2" primary containment and the B = _ <br /> Grommet for sealing the Telescoping B Straight Pipe used for 3" primary <br /> containment. <br /> Non-Contained Pipe Exits <br /> Should vent lines, vapor recovery lines or any other piping, which is not <br /> secondarily containment, use either the 4", 3", 2" or 1-1/2" standard <br /> grommet. <br /> Conduit Exits <br /> To seal electrical or monitoring conduit exits in the Sump/Riser wall use <br /> either the 1", 3/4"or 1/2" standard grommets. <br /> t <br /> -3- <br />
