4.4.2.3 Renalin® Post-Disinfection Rinse Procedure
1. After the dwell time, ensure that the drain line is in the drain with appropriate
air gap, the feed line is connected to the pre-filter outlet, and that the clear
accessory flush line is connected to the product line and placed in the drain
receptacle with the appropriate air gap.
2. Open the product valve.
3. Connect the feed line to the water supply. Turn ON the water supply.
CAUTION:
Ensure that there is flow to drain.
4. Rotate the dialyze/flush valve to the flush position.
5. Turn the F-801 RO unit ON. Rinse for 20 minutes with the Dialyze/Flush valve
in the Dialyze position until the % rejection and TDS monitors’ 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 Dialyze/Flush valve to the Flush
position briefly and then back to Dialyze three times to build-up and
release pump pressure. This aids in flushing the cleaner from the
system.
6. Test product water for disinfectant with test kit. If the test is positive, continue
to rinse until a negative test is obtained.
7. When test for disinfectant is negative, turn the F-801 RO unit OFF.
8. Close the product valve and then disconnect the clear accessory flush tubing
from the product line (white QD / valve) and store properly. Reconnect the
product line to its original connection and open the product valve.
8. Remove the “Do Not Use/Contains Disinfectant” warning label.
9. The F-801 Internal RO system is now ready for use.
NOTE:
Success of the disinfection procedure may be ascertained by taking a water culture
after completion. See the Product Water Culture Procedure in this chapter.
