Chemical/Dwell

The Chemical/Dwell program should be used when disinfecting the hydraulic system using
chemical disinfectants that can remain in contact with internal components for prolonged
periods without damaging them. Diacide HD or formaldehyde can be used with the
Chemical/Dwell program for maximum effectiveness.
To run the Chemical/Dwell 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.
3. Place the concentrated disinfectant in the small container with the yellow cap.
4. Place both concentrate connectors in their respective ports. The "Select Program" screen
appears in the control panel display.
5. From the "Select Program" screen, touch Chemical/Dwell.
