SE-4200/4400 WATER FILTRATION SYSTEM
10 P/N 1010852 Rev. C 04/06
OPERATION
Filtration Process
The filtration process includes a Filtration Cycle and a
Backwash Cycle.
During the Filtration Cycle, water enters the system
inlet port and passes through the filter elements before
exiting via the Permeate outlet.
This system is designed so that no valves are powered
during the Filtration Cycle. This allows water to contin-
ue to be filtered during a power outage and it minimizes
electrical power consumption.
After a period of time, the filters have to be cleaned.
This is accomplished through the Backwash Cycle.
During the Backwash Cycle, filtered water from one of
the cartridges is fed back through the other cartridge to
break up any debris collected on the membrane walls.
The Backwash Cycle includes a forward flush step
which then uses the feed water to flush away the loos-
ened debris from the cartridge’s membranes. The
valves are only powered during the flushing cycle and
in STOP MODE.
NOTE: Both the Filtration and Backwash cycles
can be completely automated through the Control
Panel. See the Programming section within this
manual.
