Recovery valve and then, back into the MRO, periodically test for the presence of
residual PAA at each water use outlet AND at the CHLORAMINE SAMPLE PORT (at
the front of the MRO) until less than 3 PPM of PAA is detected by the residual test
strips.
WARNING: Continue rinsing and testing with test strips until all test strips show a
negative residual result (no color change) to ensure that there is less than
3 PPM of PAA disinfecting solution remaining in the entire water system.
AmeriWater recommends using Renal Check PX Test Strips (P/N
97PX20501)
29. Record the Stop time on the Log to have a record of how long it takes for the
disinfecting solution to completely rinse out. Place a checkmark on the log to verify
that residual PAA tested negative.
30. Disinfection is complete. If the MRO was disconnected during disinfection from the
loop or storage tank, it can now be reconnected for use.
WARNING: The PAA Container PAA tubing must remain disconnected from the PAA
connection on the front of the MRO during patient treatment!
WARNING: Although it is a necessity to use a carbon filter to remove chlorine and
chloramines from the incoming water, the carbon filter that is up-stream
of the MRO, is a potential source of bacteria as it is a good growth
environment for bacteria. It is very important that backwashing carbons
be frequently done, and that the MRO is put into fast flush for 5 minutes,
minimum, before every use to minimize the bacteria growth. An MRO that
seems to be quickly re-infected after a thorough disinfection procedure
may be getting re-infected from an insufficiently flushed carbon filter.
