4. Momentarily turn the inlet water valve switch on (approximately 5 seconds), then
turn it off again. 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
(FORMALDEHYDE SPILLAGE) and prolongs the rinsing out of the disinfectant.
5. Disconnect the disinfect line from the quick-disconnect port.
6. Ensure that the FORMALDEHYDE warning label is clearly visible.
7. Remove the product rinse line and waste line from disinfect tank and RO.
8. Rinse the disinfect line and the disinfect tank with water to remove the
formaldehyde, and store it appropriately.
9. Allow the disinfectant solution in the RO to remain in contact for a minimum of
two hours, or, preferably, overnight.
NOTE:
The RO may be stored for up to one year at this time. If this is the case, a 0.5%
solution may be used instead of 4%.
4.4.1.3 Formaldehyde Post-Disinfection Rinse Procedure
1. Connect the product rinse line, input water and waste lines to the RO.
2. Ensure that the product rinse and waste lines are in the drain.
3. Turn the operate/flush valve to the flush position.
4. Turn on the inlet water valve and allow the system to rinse for 2 minutes.
5. Turn on the RO power switch and run the RO for 10 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 the chattering of the pump.
6. Rotate the operate/flush valve to the operate position.
7. Turn RO pump power switch off for 1 minute. Turn the RO pump switch on for
2-3 minutes. This will aid in the rinsing out any trapped formaldehyde in the
Millenium™ RO.
8. Continue to rinse for an additional 5 minutes.
9. Check the product line for residual disinfectant with an appropriate test kit. If the
test is positive, continue to rinse until a negative test is obtained.
10. Disconnect the product rinse line and store it.
