a) Turn the machine OFF then allow seven (7) minutes BEFORE continuing to part b.
b) Return to Dialysis Program (“Select Program” → ‘Dialysis’ → ‘Enter’)!
c) Allow [Conductivity] to increase to more than 13.0 mS.
d) Call debug screen 1.Watch FILACT for two (2) minutes. If REMAINING = 0 the problem
is solved. If still going ever = 1 return to (ABOVE) procedure number FIL- 1.0.3 (page
