2: Grid pack consists of items 9, 10, and 12 in correct quantities as shown.
3: Used on filters manufactured after Dec. 1, 1991
4: Filters manufactured before December 16, 1991 utilize a different tank top and bottom that is not interchangeable w/current units. There are no replacement Part Numbers for filters manufactured before December 16, 1991.
5: Filters manufactured before April 1, 1992 contain a different clamp band assembly. Replacement clamp band components are no longer available for these units. Replace old obsolete non-spring design clamp w/new spreing design clamp band to upgrade your filter if any components are damaged. Spring design clamp bands do not require use of a torque wrench and simplify installation of the clamp. Do not attempt to interchange components between the different clamp band designs.
