2.15 Autoflush Timer
2.15.1 Programming the Autoflush Timer
The Autoflush timer clock operates and displays in real time, but the Autoflush
feature will only work when the RO machine is operating. When the machine
is operating in the Autoflush Mode, the total flow through the machine is
increased. This provides extra cross flow which flushes the loose foulants
from the surface of the membrane elements. When the machine is operating
in the Autoflush Mode a slight drop in permeate production, as well as a
decrease in the primary and final pressures may be observed. An ideal way
to set the timer up is to program ten Autoflush sequences, with a 10 to 15
minute duration, per 24 hours. To do this, follow the procedure below.

ing the RESET KEY, the display may show
