Co- 8.4.0 Isolate Acid Pump; Co- 8.5.2 Isolate Bicarbonate Pump; Co- 8.5.4 Verify Conductivity - Fresenius Medical Care 2008K2 Troubleshooting Manual

CO- 8.4.0 ISOLATE ACID PUMP

a) Turn the machine OFF!
b) Figure right, ENSURE the Acid (red) AND Bicarbonate
(blue) Connector's O-rings AND ENSURE the filters are
clean AND the adaptor plugs are screwed in tight
c) Read parts d and e before performing them!
d) Perform the ACID (CONCENTRATE) PUMP VOLUME CALIBRATION per the Calibration booklet.
e) Are you able to enter measured burette volumes
AND 'CONFIRM' them without an "Operator Error"
(Figure right) occurring?
Yes "Operator Error" did NOT occur! See procedure number
No "Operator Error" occurred! Acid pump problem! See (ABOVE) procedure number
(page 349).

CO- 8.5.2 ISOLATE BICARBONATE PUMP

a) Perform the BICARBONATE PUMP VOLUME CALIBRATION.
b) Are you able to enter measured burette volumes AND 'CONFIRM' them without an "Operator Error"
occurring?
Yes "Operator Error" DID NOT occur! See procedure number
No "Operator Error" occurred! Bicarb Pump problem! See (ABOVE) procedure number
(page 349).

CO- 8.5.4 VERIFY CONDUCTIVITY

a) Return to Dialysis Program ("Select Program" → 'Dialysis' → "CONFIRM')!
b) From the Home screen, set [Dialysate Flow] to 800 ml/min and press 'CONFIRM'!
c) Allow fifteen (15) minutes BEFORE continuing to part d.
d) ENSURING the external flow indicators' 'bob' is moving up and down, is the external meter now within
+/- 0.4 mS of TCD?
Yes Conductivity within 0.4 of TCD! The pump calibrations fixed the problem!
No Conductivity is IS NOT within 0.4 of TCD! TWO (2) possible scenarios:
1) IF (and ONLY if) measured conductivity is LESS THAN TCD - (minus) 0.4 (i.e.
Cond is Low): Proceed to
2) IF measured conductivity is MORE THAN TCD + 0.4 (i.e. Cond is High): See
