Flush Modes
Line Pressure Front Side Flush Prior to Startup
When main power is first applied to the CP controller, the controller will first wait for a one-hour delay and will then open
the RO inlet solenoid valve and waits for an additional period of one minute. During this minute, feed water under line
pressure enters the RO, passes thru the pump and flushes through the upstream (feed water side) of the membranes and
then passes to drain. When the one-minute time is elapsed, the controller checks to see if there is sufficient incoming wa-
ter pressure to operate the RO. If there IS pressure, the controller turns on the main pump and the RO begins to produce
permeate water. If there IS NOT sufficient pressure, the entire process starts over beginning with the one-hour delay.
Line Pressure Front Side Flush Every Two Hours of Continuous Make Water
The unit will stop when it has been in a continuous make-water operation for two hours. The pump will remain off for one
minute. During this time, the inlet solenoid valve will remain open and the system will perform a line-pressure front-side
membrane flush to drain. At the end of the minute, the system will return to the “make-water” mode.
