4.3.1.2 Cleaner Recirculation and Dwell Time
1. Turn the Operate/Flush valve to the Flush position. The Flush mode will allow the
flow of cleaner only to the rejection side of the RO membrane to flush surface
particulates away. Very little or no product water will be made in flush mode.
2. Push and hold the disinfect switch to operate the RO pump for three minutes.
CAUTION:
Some pump noise (chattering) is normal in the flush position. Excessive pump
noise (chattering) can be damaging to the pump. The RO is in “flush” from the full
open (flush) position to just before the fully closed (operate) position. Adjust it by
partly closing the flush valve to reduce chattering of the pump.
CAUTION:
DO NOT ALLOW PUMP TO RUN DRY. Damage will occur if pump is run dry.
CAUTION:
Check that there is waste flow within 10 seconds. If not, release the button (switch)
and verify that the disinfect-line is connected properly.
CAUTION:
Do not allow air or foam to be drawn into the RO system, as this will damage the
pump.
NOTE:
The cleaners will foam; this is normal. If using a closed container, provide a vent
to the atmosphere to relieve pressure.
3. Let the RO stand dormant with cleaning solution in it for thirty minutes.
4. Remove the waste hose from the cleaning solution and place it in the drain.
5. Using the disinfect switch, turn the RO on and flush approximately 1/2 gallon of
the solution to the drain. This prevents fouling the cleaning solution with the first
