Type Action Required
Opening After entering Dialysis, verify that the conductivity limits are as
Screen desired.
Dialysate 1) Check to see if :
Alarm

Dialysate flow is on.

The correct concentrate is selected in the "Dialysate" screen
and the concentrate supply lines are connected to
appropriate concentrate sources.

The prescribed concentrate and the correct baseline Na+ and
Bicarbonate values are displayed in the "Dialysate" screen.

The supply of concentrate is adequate.

The concentrate has been mixed properly, (i.e. bicarbonate
mixed well with RO water).
2) Verify that the concentrate connectors are sucking concentrate. If
not:

Turn off dialysate flow and disconnect the concentrate
suction connectors from their wands.

Check for clogged filter screens in the connector handles,
especially the bicarbonate connector. Clean if necessary.
Re-assemble the concentrate connectors. Verify that the
connectors and filter assemblies are tightly screwed together
with no air leak.

Check that the O rings on the tips of the concentrate
connectors are not damaged or missing.

Reconnect the connector to the concentrate source. Turn on
dialysate flow and recheck the connectors for suction. If
suction is present, allow 5 minutes for conductivity to reach
the prescribed level.
If suction is not present in both connectors, discontinue treatment and
remove 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.
