SECTION 9: MAINTENANCE

9.5 Combined Maintenance Procedure

Some maintenance procedures are significantly
easier if they are performed at the same time. We
recommend that you replace screen panels, gasket
seals, and the drum seal at the same time.
These procedures maintain standard wear items
that should be replaced on a regular schedule,
and contain common steps that only need to be
performed once if the maintenance procedures are
performed in unison. In addition, there is increased
service access that facilitates maintenance.

9.5.2 Procedure
Always follow the proper shutdown procedure
(Section 8.2 or 8.3) before performing any
maintenance on the Rotofilter.
1. Drain or pump the enclosure.
2. Remove the Rotofilter lid. If the model has
removable side panels, it may be beneficial to
remove them for more service access.
3. Turn on power to the Rotofilter control panel.
4. Rotate the drum in Manual Mode until a screen
is accessible.
