4.3.2.2BIOSAN™ 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.
