4.3.2.2 BIOSAN™ Recirculation and Dwell Time
1. Rotate the Operate/Flush valve to the Operate position. This will allow the
BIOSAN™ to pass from the rejection side of the membrane through to the
product side of the membrane for total system exposure to the cleaning solution
once the RO is turned on in disinfect mode (step #2).
2. Push and hold the disinfect switch to operate the RO pump for three minutes.
CAUTION:
Check that there is waste flow within 10 seconds. If not, press the disinfect switch
to turn RO pump off and verify that the disinfect line is connected properly.
CAUTION:
DO NOT ALLOW PUMP TO RUN DRY. Damage will occur if pump is run dry.
CAUTION:
Do not allow air or foam to be drawn up into the RO unit, as this will damage the
pump.
NOTE:
Biosan™ will foam; this is normal. If using a closed container, provide a vent to
the atmosphere to relieve pressure.
3. Turn the Operate/Flush valve to the Flush position and hold the disinfect switch
for an additional 3 minutes. The Flush mode will allow the flow of cleaner only to
the reject side of the RO membrane to flush particles away. Very little or no
product water will be made.
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 by
partly closing the flush valve to reduce the chattering of the pump.
4. Allow the BIOSAN™ to dwell in the RO for a minimum of one hour.
