11.4 Removing Screen Panels
and Gasket Seals
Some maintenance procedures are significantly
easier if they are performed at the same time.
We recommend that you replace the screen panels,
gaskets, and the drum seal at the same time.
This procedure describes removing screen
panels and gasket seals only. For the combined
maintenance procedure, see Section 9.5.
To remove screen panels and gasket seals, you will
need to rotate the drum until you are able to access
the fasteners at both ends of the screen clamp and
center retainer bar. Each screen clamp holds down
2 screen panels.
Remove the Rotofilter lid. If the model has
removable side panels, it may be beneficial to
remove them for more service access.
