HYDRAULIC CONNECTIONS
Each flanged connection nozzle (N1 & N2) on the C+ filter has two ¼”
threaded couplings. One may be used to install a pressure gauge or other sensor
equipment. The other ¼” coupling will be used to connect hydraulic tubing from
the differential pressure switch to the filter. The high pressure line is fitted to the
inlet, and low pressure fitted to the outlet.
HYDRAULIC PISTON
The piston (8) is mounted on the flush end of the filter. ¼” tubing must be
installed from the fitting located on the back of the piston to the hydraulic
connection (K3) on the flush outlet (N3). A filter is installed on the hydraulic
tubing to protect the piston.
Filter Performance
NORMAL OPERATION
During normal operation of the filter, dirty water enters through the inlet and
passes through the coarse screen. Any abnormally large debris is caught here
and prevented from possibly damaging the fine screen or particle remover.
Water then travels down the center of the filter and is strained across the fine
screen. As water passes from inside the screen to outside, suspended particles
are trapped on the fine screen and continue to buildup, eventually creating a drop
in pressure at the outlet of the filter.
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.
