173 Troubleshooting
Type Action Required
Water Make certain the correct bicarbonate is connected to the machine
Alarm and that there is enough concentrate available. Wait five minutes for
conductivity to stabilize. If the appropriate conductivity cannot be
reached:
1) Plug the blue bicarbonate connector into its port.
2) Wait one minute and then re-connect the bicarbonate connector
to the liquid bicarbonate source.
3) Wait five minutes for conductivity to stabilize.
If the conductivity alarm persists,
1) Turn off the dialysate flow by selecting and confirming the
Dialysate Flow on/off toggle-button on the "Dialysate" screen.
2) Disconnect the concentrate suction connectors from their wands.
3) Check for clogged filter screens in the connector handles,
especially the blue bicarbonate connector. Clean if necessary
with purified water. Re-assemble the connector handles. Verify
that the connectors and filter assemblies are tightly screwed
together with no air leak.
4) Insert the red and blue concentrate connectors back into the
wands and place the wands in the jugs. Turn the dialysate flow
back on by selecting and confirming the Dialysate Flow on/off
toggle-button on the "Dialysate" screen.
If the conductivity alarm still cannot be cleared, discontinue treatment,
rinse back the patient's blood and disconnect the patient from the
machine. Perform an Acid Clean program followed by a complete
rinse cycle. Test machine operation. If conductivity alarm persists,
take the machine out of service and alert a qualified service
technician.
Alarm Turn machine power off and back on. If alarm is not cleared, return
the blood to the patient if alarm occurs during treatment. Take the
machine out of service and alert a qualified service technician.
