FIL- 3.7.0 FILACT = 1 CONSTANT OR INTERMITTENT

READ THIS PROCEDURE before performing it:
To avoid damage turn the machine OFF!
A)
B) SEVEN (7) possible bad components (see Component List below). One at a time, swap in each with
known good then in between, continue with parts C through H to test each new component.
Component List: 1) CBE board; 2) Sensor Board; 3) Sensor Board cable;
4) Functional Board ; 5) Chamber #69's cap (Figure right);
6) Distribution board; 7) Motherboard
C) When it is time to swap in the Sensor or Functional board, to prevent
"Cond Offset" Failure", place the machine into T and C Mode (refer to
OPERATING MODES, page Error! Bookmark not defined.)).
D) When it is time to swap in Chamber #69's cap BE SURE to attach the Air
Sensor's Connector wires to Chamber #69's probes to the new cap.
E) Turn the machine on and return to Dialysis Program ("Select Program →'Dialysis' → 'CONFIRM').
F) From the Home screen, allow [Conductivity] to increase to at least 13.0 mS.
G) Allow thirty (30) seconds BEFORE continuing to part H!
H) Call debug screen 1. Watch FILACT for two (2) minutes. If EVER = 1 return to part A and swap in the
next component in the list. When FILACT remains = 0 the last component swapped in is the problem.
