8. After the first panel has been removed, remove
the retainer bar from the drum. The retainer
bar may be held in place by bolts or hex head
screws.
9. Once the retainer bar has been removed, the
second screen can be taken off. The screen
gaskets will be the only things remaining on
the drum periphery for this section of the drum.
Inspect screen gaskets whenever screen panels
are removed. We recommend replacing screen
gaskets anytime you remove screen panels.
10. Use a razor blade to gently remove the screen
gasket from the frame. Use acetone (or
equivalent solvent) to remove glue residue.
11. Remove all remaining screen gaskets from drum
periphery. Repeat steps 1 through 10 for other
screen clamp sections.
12. After all screen panels and gaskets are
removed, pressure wash the inside of the filter
box, drum and solids trough. Wipe off and dry
drum periphery.
