CO- 5.0.0 UNSTABLE CONDUCTIVITY / CHECK PRESSURES
a) ENSURE Loading Pressure (Rinse port gauge) is cycling between its PEAK of somewhere
between 23 and 25 psi AND to NEVER LOWER than 11 psi.
b) Temperature influences Conductivity. If it changes more than +/- 0.2° C per minute address the
temperature problem first!
c) Turn the machine OFF to avoid air locking the deaeration pump!
d) The deaeration gauge is used next. ENSURE it reads
0 inHg before installing it!
e) Figure right, tee a gauge into the INLET tubing of the
Deaeration Pump.
f)
IMPORTANT!
Return to Dialysis Program (“Select
Program” → ‘Dialysis’ → ‘CONFIRM’)!
g) Is Deaeration Pressure OKAY? Refer to Appendix A
(page 667) for what pressure should be.
Yes Deaeration OKAY! Position the gauge so that
tubing in NOT pinched then see procedure
number
CO- 5.1.0 (page 350).
No NOTE this page number, as you will return here, THEN proceed to
page 498

DEAERATION PROBLEMS .
CO- 5.1.0 CHECK FOR AIR LEAK
Per the Figure (above, right), using a flashlight, for ONE (1) MINUTE, WITHOUT LOOKING AWAY, check
for air bubbles flowing MOVING through the clear tubing at Conductivity Cell #7. Is air seen?
Yes Air seen! Proceed to
page 495
, procedure number AIR- 1.0.5 .
No No air seen! See procedure number CO- 5.3.0 (page 350).
CO- 5.3.0 NO AIR SEEN / ISOLATE PUMP ACCURACY
Call debug screen 0.Watch Acid versus AAcid (Figure right) for one (1) minute. The
values don’t matter but should remain /- 3 of each other?
Yes AAcid = Acid! See procedure number CO- 5.3.1 (page 350).
No AAcid is NOT remaining /- 3 of Acid! Proceed to
page 397
, SECTION 6 -
CONCENTRATE PUMP ERRORS .
CO- 5.3.1 CHECK BICARBONATE STEPS
Watch Bic versus ABic (Figure right) for one minute. Remaining /- 3 of each
other?
