3. Identify the appropriate frame gasket for the intended application (refer to the parts list cross reference on the following page for more information).
4. Clean the mullion surfaces that will contact the frame pads. Using an approved solvent or cleaner, clean the surfaces of all oils and other
contaminants.
5. Remove the liner from the frame gasket and apply it to the matching surface of the mullion ensuring the holes and edges align as required. (There may be
excess holes in the frame gasket without a corresponding hole in the mullion as the gaskets are designed for multiple application locations.)
6. Smooth out the frame gasket onto the mullion surface by forcing out any remaining air bubbles.
7. Tear the excess gasket material at the serrations in areas where the gasket overhangs as shown in Figure 6 and 7.
