Chapter 5—Disinfection and Maintenance

Chemical/Rinse Program

The Chemical/Rinse program should be used when disinfecting the hydraulic system using
corrosive chemicals, such as bleach. The Chemical/Rinse program consists of a disinfection
cycle followed by a water rinse cycle. Because bacterial growth can begin soon after the
rinse cycle, the machine should be disinfected again if it has remained idle more than 48
hours after its previous disinfection.
Caution: To avoid internal damage these chemicals should not remain in contact with the
machine. Rinse your machine immediately after completing the disinfection.
To run the Chemical/Rinse program:
1. Attach a sign to the front of the machine that identifies the chemical being used to
disinfect the machine.
2. Ensure that both dialysate lines are on the shunt and both concentrate connectors are in
their respective ports.
3. From the "Select Program" screen, touch Chemical/Rinse.
4. The "Chemical/Rinse" screen appears in the display (see Figure 61). The progress of the
disinfection program is indicated by the horizontal bar. The program starts with a 45
second pre-rinse. The message, " Rinsing Lines, Please Wait " is displayed in the Status
Box.
Note: If the 'HE Leak Test' Service Mode option is selected (software versions 3.39 and
later), the machine will run a four minute pressure holding test after the 45 second pre-rinse.
If the first test fails, a second test will automatically run.
If the second test fails, the machine will display a "System Leak, Can't Run" message,
meaning that the Chemical/Rinse program can no longer be run due to a leak detected in the
Heat Exchanger. However, the machine will still be able to run Heat Disinfection programs
and hemodialysis treatments per unit protocol. Call a qualified service technician.
