Co- 6.8.0 Conductivity Is Not Between 13.0 And 14.2 - Fresenius Medical Care 2008K2 Troubleshooting Manual

CO- 6.8.0 CONDUCTIVITY IS NOT BETWEEN 13.0 AND 14.2

Based on the external meter's reading, TWO (2) possible scenarios:
1) IF (and ONLY if) LESS THAN 14.5 mS: Proceed to
2) IF MORE THAN 14.5 mS: See parts a THROUGH d below:
a) ENSURE the blue (bicarb) connector is not accidently plugged into acid; the red (acid) connector
MUST be in acid!
b) Figure below, clamp the tubing at Valve #29.
c) ENSURE the external flow indicator's 'bob' continues to move up and down
d) Allowing up to fifteen (15) minutes, does the external meter's reading stabilize between 13.0 and
14.4 (Yes or No)?
Yes Conductivity between 13.0 and 14.4! Remove the clamp and allow (7) seven minutes.
If the meter's reading becomes more than 14.5 mS again this confirms a problem with
Valve #29. TWO (2) possible bad components: 1) Bad Actuator-Test Board OR;
2) Bad Valve #29.
No Conductivity is IS NOT between 13.0 and 14.4! See procedure number
362).
