Adjust the REJECT flow control knob so that the PAA will be drawn into the MRO in
about 2 minutes. (Figure 5.1) The REJECT flow amount will have to be determined
the first time the PAA is drawn in, and noted so that it will empty the container in about
2 minutes.
17a. Continue holding the ENTER key until the PAA container is empty, then immediately
release the ENTER key.
17b. If disinfecting the MRO while connected to a small direct-feed loop:
Draw a complete PAA container into the MRO (with the REJECT flow amount
adjusted as needed described in step 12).
Release the ENTER key, then refill the PAA container, reconnect the PAA
container to the MRO, press & hold the ENTER key, and draw the 2
nd
PAA
container into the MRO.
When the 2
nd
PAA container’s contents reaches the blue line (or a level
approximately 2” from the bottom) on the PAA Container, continue holding the
ENTER key, but be prepared to release the ENTER key when the PAA
container is emptied (Approximately ¼” of the solution will remain in the bottom
of the plastic container). Avoid sucking air into the system.
NOTE: The ENTER key must be held until all the PAA is drawn into the MRO.
a. Avoid stopping and starting the disinfect function which may cause a thermal
overload of the MRO pump.
b. Releasing the ENTER key may cause the system to lose its prime preventing all of
the disinfectant from being drawn into the MRO.
c. Approximately ¼” of the solution will remain in the bottom of the PAA container.
This is normal and may be emptied down the drain after the entire process is
complete.

strips (P/N 97hp20401):
a. Using a test strip, test the water the REJECT WATER TO DRAIN hose, the
result must be at least 1% (500 ppm).
b. Use another test strip at the PRODUCT WATER hose, the result must be at
least 0.5% (250 ppm).
