filtration process
Water filtration in the UFL Series is accomplished using
two modes:
• Flush Interval (
fi
on the LED display)
• Flush Duration (
fd
on LED display).
During the Flush Interval mode, water enters the inlet
and flows through the filter element before exiting the
Permeate outlet as usable product water. After a cer-
tain period of time, depending upon water quality, the
filter has to be cleaned. This is accomplished through
the Flush Duration Mode. During this mode, the drain
valve opens and flushes the membrane to remove
debris collected inside the membrane walls.
nOte: both the flush Interval mode and the flush
Duration mode can be automated by programming
the timer. During the flush Interval mode, the valve
is not powered in order to keep water filtering during
a power outage.
