SECTION 13: SUPPORT WHEEL MAINTENANCE

13.1 Overview

Rotofilters use bearing-mounted urethane wheels
for supporting the rotating drum. These should
be considered a normal wear item and should be
replaced at a regular service interval.
Allowing the wheels to sustain significant wear or
fail will cause the drum to become deformed, which
could cause filter failure. Pentair recommends that
you replace support wheels at 1 year intervals.

13.3 Greasing the Support Wheels

Greasing the drum wheels prevents water entry into
the wheel bearing. Grease should be applied until it
discharges from the bearing seals.
