Filter Basics The Rain Bird C+ Series is a self cleaning screen water filter. The major components include the Filter Housing (1), Coarse Screen Pre-Filter (11), Fine Screen Filter Element (2), Particle Remover (3), Hydraulic Piston (8), and Backwash Valve (12).
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.
C+ SERIES FILTER - NORMAL OPERATION This drop in outlet pressure is monitored by the differential pressure gauge, which at seven PSID (pounds per square inch differential) sends a signal to the controller to initiate a backwash cycle.
This creates a low pressure path inside the particle remover, which acts as a vacuum at the end of the suction nozzles, removing the built up debris from the inside of the fine screen. C+ SERIES FILTER - BACKWASH CYCLE FLUSH INTERIOR OF FILTER...
