CO- 1.0.6 "NO AIR" ALWAYS / ISOLATE LOADING PRESSURE
ENSURING
a) the Loading Pressure gauge (yellow connector) reads 0 psi before inserting it
into the Acetate/Acid rinse port. * or else pressure always read low
b) Loading Pressure may not cycle but is 'OKAY' if it achieves a peak of between 23 and 26 psi. TWO (2)
possible scenarios:
1) IF (and ONLY if) pressure is 'OKAY': Leaving the gauge installed, see procedure number
CO- 1.0.6.2 (page 356).
2) IF pressure is NOT 'OKAY': Leaving the gauge installed, proceed to
number F- 1.0.7.
CO- 1.0.6.2 LOADING PRESSURE OKAY / ISOLATE INTERMITTENT FLOW ERROR
a) Call debug screen 0.
b) WITHOUT LOOKING AWAY, watch Flow Error for three (3) minutes OR until if it EVER = 1, even just
once, indicating a Flow Error:
1) IF (and ONLY if) Flow Error ALWAYS = 0! Proceed to
CO- 1.0.7
NOTE!
If [Conductivity] has been 'drifting' between good and high watch Flow Error for up
to six (6) minutes to catch a potentially VERY intermittent Flow Error!
2) IF Flow Error EVER = 1 even just once: Proceed to
IN DIALYSIS PROGRAM.
CO- 1.0.6.4 BC SWITCH NEVER = 897 PART 1
a) If previously removed, return the Air Sensor's female connector to
position
FROM THE LEFT. Figure below, if CBE modified it plugs into the CBE board pin for pin!
b) See procedure number CO- 1.0.7 (page 357).
