SECTION 5, DISINFECTING THE SYSTEM
5.1
DISINFECTING THE SYSTEM
The MRO system should be disinfected according to specifications of your medical facility
director. As a general guideline, AmeriWater recommends that the system should be disinfected
at least monthly. In addition, AmeriWater recommends that the system be disinfected if it has not
been: used for 24 hours; flushed at least every 8 hours; or “packed” in BioTrol for storage up to
two weeks.
Be sure to refer to the Start-Up Log in Section 4.5. This will help you verify that all steps
are performed and recorded to disinfect the system properly.
5.1.a. DISINFECTING THE MRO ONLY OR WITH A SMALL LOOP SYSTEM
Note: A “small loop system” can be
defined as one where all points in the
loop can easily be disinfected by
drawing less than 5 containers of PAA
solution into the MRO and loop
system. If this can’t be accomplished,
refer to section 5.1.b that describes
disinfecting a “large” loop system.
1. Switch off the MRO by pressing the
POWER key (the display will show
STANDBY).
Disconnect any dialysis machines
from the Direct Feed Loop or
Central System from the water loop
before starting the disinfection
procedure. Disinfectant for the
MRO or loop must never be allowed
to enter a dialysis machine.
WARNING: T he disinfection mode will allow PAA to flow through the PRODUCT WATER
hose
. This is to allow disinfection of the hoses and the connected “small”
direct-feed water loop.
If the “small” direct-feed water loop is to be disinfected with the MRO, fill
and draw the PAA solution container at least twice and up to 5 times to
allow sufficient volume into the loop for complete disinfection.
3a.
To disinfect only the MRO that is connected to a Storage Tank, disconnect the
PRODUCT WATER hose from the tank and place along with the REJECT WATER TO
DRAIN hose in a sink.
