HEAT DISINFECTION
8.1
What is being disinfected?
The Centurion Plus Heat disinfection device is intended to disinfect the hose used to feed a Hemodialysis
machine with purified RO water. Typically, the RO and Hemodialysis machine are disinfected using their
own automated disinfection processes. Neither the RO or Hemodialysis machines disinfection procedures
disinfect the feed water hose which leaves it up to the end user to chemically disinfect. The Purpose of
the Centurion Plus Heat disinfection device is to disinfect this hose between the RO and Hemodialysis
machine using an automated heat disinfection cycle.
8.2
Frequency
Disinfection of the feed water hose to the Hemodialysis machine is required monthly. AmeriWater
recommends at least one weekly heat disinfection of the feed water hose for the hemodialysis machine.
Environmental conditions may warrant more frequent disinfections.
