19b. If the MRO is connected to a small direct-feed loop during disinfection, then the entire
loop must test positive for PAA throughout the loop. Using a fresh test strip at each
dialysis machine water outlet, test the water. The result must be at least 0.5% (250
ppm).
19c. If the small direct-feed loop is using a Product Recovery, the presence of PAA must
test positive at the Chloramine Sample Port at the front of the MRO in addition to each
dialysis machine water outlet. The result must be at least 0.5% (250 ppm).
NOTE:
Water loop systems will vary in size and in volume for each installation. If a small
loop is to be disinfected along with the MRO, then PAA must be drawn into the
MRO using only the disinfection function, pumped into the loop by the MRO through
the PRODUCT WATER hose connection. After each container of PAA solution is
drawn into the MRO, then the MRO must be stopped without delay, and each water
outlet must be tested for PAA at the minimum amount. Continuing to run the MRO
after all the PAA solution is drawn out of the PAA container will only result with
diluting the strength of the PAA, which reduces the disinfecting capability.
If the PAA at each water outlet has not been found to be positive at the minimum
required amount, another container must be drawn into MRO, and into the loop,
until the minimum strength is tested and verified using a PAA test strip. If the
minimum required level of PAA cannot be achieved after a reasonable number of
volumes from the PAA container (usually around 5, or determined by your facility
manager), refer to the “large” loop disinfection procedure outlined in the following
section.
UNTIL THE PAA IS FOUND TO BE POSITIVE AT EACH WATER OUTLET TEST
POINT AT 0.5% MINIMUM, THE LOOP SYSTEM CANNOT BE RELIABLY
DISINFECTED.
20.
Label the MRO with appropriate WARNING signs (Example: “DO NOT USE /
CONTAINS DISINFECTANT”).
21.
To assure that the MRO will not be accidently used for dialysis, leave the MRO in the
DISINFECT ENABLED mode, and allow the PAA solution to soak for 60 minutes
within the MRO, and in the loop (if connected to one).
WARNING:
Soaking longer than 12 hours may cause damage to the membrane.
22.
Record the Start and Stop times on the Log to have a record of how long the
membrane soaked in PAA disinfecting solution.
23.
Flush the residual PAA from the disinfectant draw plumbing.
a.
Rinse and fill the PAA Container to the red line with dechlorinated water from the
Incoming Tap Water Test Port and connect the PAA tubing to the PAA
connection on the front of the MRO.
