Rain Bird C+ SERIES Operation And Maintenance Manual - Installation Requirements

Installation Requirements
C+ Series filters may be mounted directly on the inlet (N1) and outlet (N2)
flanges, and positioned in any orientation. Isolation valves should be installed at
the inlet and outlet, and a bypass valve should be installed between the flanges.
This will allow the filter to be taken offline without disruption to water flow.

Valve
There should be adequate clearance around the filter to allow for easy
maintenance access, including a minimum of 24” from the back (piston side). The
minimum clearance on the front (cover) depends on the model. There must be
enough room to remove the coarse screen and fine screen periodically.
FLUSH LINE
The piping for the flush valve must have no backpressure. It is strongly
recommended to use oversized piping to accommodate this requirement. For a
1” valve, 1.5” or 2” pipe must be used.
To minimize backpressure on the flush line, it is also important to avoid elevation
gain in the flush line. Even a small elevation gain can reduce the filter’s ability to
perform an effective backwash cycle. If flush water must be transported to higher
elevation, it is recommended to pipe the flush line to a storage tank first, and then
pump out to higher elevation.
