24.
After rinsing with the REJECT VALVE allowing full flow for at least 15 minutes, turn the
REJECT VALVE clockwise until the REJECT flow is approximately equal to the
PRODUCT flow (normal operation reject flow). Allow the MROZ to run for 15 more
minutes.
25.
After the first 30 minutes, repeat 15 more minutes of full flow through the REJECT
VALVE + 15 minutes of operation a normal operation reject flow. This will give a total
of 60 minutes of running time to remove the disinfectant. Begin to test for the presence
of PAA with residual test strips (
Renal Check PX Test Strips (P/N 97PX20501)
at
product and reject hoses.
26.
If the MROZ is connected to a loop that is being recirculated back through a Product
Recovery valve and then, back into the MROZ, periodically test for the presence of
residual PAA at each water use outlet AND at the CHLORAMINE SAMPLE PORT (at
the front of the MROZ) until no trace 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 are NO
traces of PAA disinfecting solution remaining in the entire water system.
AmeriWater recommends using Renal Check PX Test Strips (P/N
97PX20501)
26.
Record the Stop time on the Startup 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.
27.
Disinfection is complete. Pull an AAMI sample.
28.
If the MROZ was disconnected during disinfection from the loop or storage tank, it can
be reconnected for use once it is producing water within the acceptable conductivity
range.
WARNING: The PAA Container PAA and tubing must remain disconnected from the
PAA connection on the front of the MROZ 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 MROZ, is a potential source of bacteria. It is very important that
backwashing carbons be frequently backwashed and that the MROZ is put
into fast flush for 5 minutes, minimum, before every use to minimize the
bacteria growth. An MROZ that seems to be quickly re-infected after a
thorough disinfection procedure may be getting re-infected from an
insufficiently flushed carbon filter.
