Millenium™ RO System by GE Osmonics

4.4.2.2 Renalin® Disinfection and Dwell Time

1. Verify that the operate/flush valve is in the OPERATE position.

2. Use the disinfect switch to circulate the solution through the system for five

minutes. After three minutes of circulation, test the product line for the presence

of disinfectant. Continue circulating until a positive test is achieved.

CAUTION:

Do not allow the solution temperature to climb above 25°C during this step. Failure

to control temperature will result in rapid deterioration of the membrane, resulting

in poor rejection.

3. Place the product and waste lines into a drain. Protect the product line from

contamination.

4. Using the disinfect switch, turn the RO on and run solution to the drain until the

container empties. Alternately, the container may be carefully poured in the drain.

5. Turn off the RO; do not operate the RO dry.

CAUTION:

Do not allow air to be drawn up into the RO unit as this will damage the pump.

6. Momentarily turn the inlet water valve switch on (approximately 5 seconds.) This

allows the water to rinse the disinfectant from the disinfect line and quick-

disconnect connection.

WARNING:

Failure to perform this step creates a potentially dangerous situation

(DISINFECTANT SPILLAGE) and prolongs the rinsing out of the disinfectant.

7. Remove the disinfect line from the disinfect port. Rinse, drain and store it.

8. Allow the RO to soak in the disinfecting solution for 36 minutes -12 hrs. Thirty-

six minutes contact time is expected to result in 90% bacteria kill; 12 hours is

expected to kill 99% of the bacteria. The minimum amount of soak to achieve

disinfection is better for the membranes.

4.4.2.3 Renalin® Post-Disinfection Rinse Procedure

1. Ensure that the product rinse line is connected to the RO.

2. Ensure that the product rinse and waste lines are connected to the drain.

3. Rotate the operate/flush valve to the flush position.

4. Turn on the inlet water valve switch and allow the system to rinse for 2 minutes.

5. Turn the RO pump power switch on and run the RO for 10 minutes.

CAUTION:
