4.3.2.3 BIOSAN™ Post-Cleaning Rinse Procedure

1.Using the disinfect switch, turn the RO on and run the cleaning solution to the drain until the container is empty.

CAUTION:

DO NOT ALLOW THE PUMP TO RUN DRY. As an alternative, the solution may be poured in the drain.

2.Disconnect the disinfect line from the RO.

3.Ensure that the water supply to the RO system is on. If it is partially closed, rotate the operate/flush valve to the full flush position.

4.Push the inlet water valve switch to the ON position. Let water flow to the drain for one minute.

5.Rotate the Operate/Flush valve to the operate position.

6.Set the RO pump power switch in the ON position. Rinse for 20 minutes with the Operate/Flush valve in the Operate position until the % rejection and TDS monitor displays normalize (e.g. 'usual' % rejection and 'usual' TDS reading). Refer to your operating log for 'usual' readings and compare to the pre-cleaning values.

A.During this rinse period, rotate the Operate/Flush valve to the Flush position briefly and then back to Operate three times to build-up and release pump pressure. This aids in flushing the cleaner solution from the system.

7.Test the product water for post cleaning pH and compare it to the pre-cleaning pH level. The values should be the same or very close. If it is not, continue rinsing in the Operate position until equalization of the value occurs.

8.When all of the parameters (% Rejection, TDS, pH) have normalized, operate the RO for an additional 20 minutes in rinse mode.

9.Turn the RO pump and inlet water valve switches OFF. Disconnect the product rinse line, and drain and store it.

10.Reconnect the product line to its original connections.

11.Remove the 'Do Not Use/Contains BIOSAN™' warning label.

12.The Millenium™ RO System is now ready for use.
