FIL- 1.0.3 DEAERATION PRESSURE OKAY (2)

Because the machine was off, [Conductivity] will be unstable! The following procedure requires three (3)
minutes during when [Conductivity] MUST stabilize to between 13.0 and 14.4 mS!
OPEN THE SHUNT DOOR AND LEAVE IT OPEN TILL INSTRUCTED!
a)
b) Call debug screen 0. WITHOUT LOOKING AWAY watch Flow
three (3) minutes
Error for
indicates a masked Flow Error! TWO (2) possible scenarios:
1) IF (and ONLY if) Flow Error ALWAYS = 0! See procedure number
2) IF Flow Error EVER = 1: Proceed to
PROGRAM.

FIL- 1.0.4 ISOLATE 'OUT OF BYPASS' CIRCUIT

a) From debug screen 0, Figure right, TWO (2) IMPORTANT
checks:
CHECK #1: Pre Dialyzer Temperature MUST BE stable*
BETWEEN 35.0 and 39.0° C!
CHECK #2: Pre Dialyzer Conductivity MUST BE stable*
BETWEEN 13.0 and 14.4 mS!
*
Stable = NOT changing more than 0.1 per minute! If Temperature is about 37.0° C and
Conductivity about 14.0 mS but either one bounces' more than 0.3 may indicate a large air leak
that must be located and repaired!
b) See procedure number
FIL- 1.0.5 STABLE CONDUCTIVITY / ISOLATE OLC
A bad On Line Clearance (OLC) component may cause Filling Programs EVEN if OLC is not activated or
used! From debug screen 0:
Figure right
a) , if the POST Dialyzer Cond symbol
appears see part b. If NOT skip to procedure number
FIL- 1.0.6 (page 414).
b) Are PRE AND POST Dialyzer Conductivity within 0.4
mS of each other (Yes or No)?
Yes PRE AND POST Conductivity within 0.4
mS of each other! Proceed to
procedure number
No PRE AND POST Conductivity ARE NOT within 0.4 mS of each other! See procedure number
FIL- 1.0.6 (page 414).
