9.2 Maintenance Considerations

Some maintenance procedures require the
Rotofilter to be dry. To perform these procedures,
Frame (RFF) models will need to have sumps that
can be drained or pumped. Molded (RFM and
Ultraviolet (RFUV) models have integrated drains
in their enclosures.
Some maintenance procedures are significantly
easier if they are performed at the same time. We
recommend that you replace screen panels, gasket
Manual Section
seals, and the drum seal at the same time.
These procedures maintain standard wear items
that should be replaced on a regular schedule.
Procedures contain common steps that need
only be performed once if the maintenance
procedures are performed in unison. In addition,
there is increased service access that facilitates
maintenance.
This manual provides the procedures as a
combined unit in Section 9.5, and also as
separate tasks.

9.3 Checking Flow and Water Levels

Check flows at least once per day to ensure that
the water levels inside and outside the drum
remain within the acceptable range. Minimum
and maximum water levels are identified on the
specification documents.
Flow may need to be altered to maintain the
correct balance between water inside and
outside of the drum.
