5. Remove the 2 screws that attach the diaphragm housing (item 14) to the inlet body (item 20) and
separate
6. Remove the pin (item 16) and slide out the lever (item 15). When replacing the lever, make sure the

8. Using a 3/4" socket wrench, remove the valve disk and holder assembly (item 23).

compression is removed.
2. If necessary, disconnect the remote vent pipe.
