5.2 DISINFECTING AN MRO CONNECTED TO A “LARGE” LOOP
Disinfecting and MRO connected to a “large” loop system requires a different procedure.
Rather than using the
“DISINFECT”
mode, the
“‘CIP”
(Clean In Place) mode will have to be
accessed to assure complete circulation of the PAA through the MRO, through the large
direct feed loop, and back to the MRO.
WARNING:
Continuous recirculation of the PAA solution will result with heating
the water in the system, and can cause a safety or health hazard. PAA
is a very pungent irritant that only gets worse when warmed. Circulate
the PAA solution only enough to achieve a minimum required amount
of 0.5% at each water outlet in the loop system, and at the Product
Recovery water return to the CIP2 tank. Once the minimum amount is
achieved at all points, stop the circulation, and allow the PAA solution
to soak in the system as described later in this document.
Note: The purposes of disinfecting and cleaning are distinctly different. With disinfection,
exposure only to the disinfectant is required to destroy harmful bacteria. On the other
hand, cleaning requires exposure by recirculation to chemically react and dissolve bio-
film and/or mineral deposits that only can be removed by continuous re-exposure of
the surfaces to the active chemicals that are in the cleaning solutions. Therefore, the
MRO during “CIP” will continuously re-circulate and heat the chemicals (by the
pumping action) through the CIP2 attachment until the procedure is stopped by direct
intervention of the operator. This is good for cleaning, but great care must be
exercised for disinfection.
1.
To clean an MRO, an
AmeriWater CIP2
cleaning system is required to be connected
to the MRO.
2.
Place the MRO in “STANDBY”, turn off the water supply and disconnect the MRO feed
water inlet hose from the Product Recovery unit, and connect it to the CIP2 pump
outlet.
3.
Disconnect all dialysis machines from the water direct feed loop system to prevent
disinfectant from entering those machines.
4.
Consult the CIP2 manual for detailed instructions.
