SECTION 5 - CONDUCTIVITY / ON LINE CLEARANCE PROBLEMS
External leaks, “No Water” and Flow Errors cause Conductivity problems. If either occur at ANY TIME
address them first! To avoid error observe ALL stated times below!
A) ENSURE Dialysate Flow is ON (Flow on/off lamp NOT blinking)!
B) From the Home screen, ENSURE [Dialysate Flow] and has been
on and set to 800 ml/min for five (5) minutes!
C) If [ Conductivity ] is less than 12.6 mS, Figure right, ENSURE BOTH
connector plug O-rings are present! If not this may be the problem!
D) If the Automated Tests are running (screen reads “Test:.…”) allow them to finish.
E)
If installed, remove the ‘dummy chamber’ from the Level Detector .
F) Select the [ Temperature ] window. Is “Temp Setting”
ALREADY = 37.0° C?
Yes See part G.
No Adjust “Temp Setting” to 37.0° C THEN continue to part G.
G) Press ‘CONFIRM’ to return to [ Temperature ].
H)
DO NOT RESET ALARMS!
I) Call debug screen 0. If Flow Error EVER = 1, even just
once, there is a Flow Error! WITHOUT LOOKING AWAY
watch it for, TWO (2) possible scenarios below:
Scenario #1: IF “Temp Setting” was already 37.0° C (it was NOT necessary to adjust it), TWO (2)
MINUTES OR until if Flow Error EVER = 1.
Scenario #2: IF “Temp Setting” was not already 37.0° C (it was necessary to adjust it), FOUR (4)
MINUTES OR until if Flow Error EVER = 1.
J) Is Flow Error is ALWAYS = 0?
Yes Flow Error ALWAYS = 0! See part K.
No Flow Error = 1 even if just once! Proceed to

, SECTION 1 - FLOW ERRORS IN
DIALYSIS PROGRAM
K) Using a flashlight, ENSURE large air bubbles are NOT moving into the machine through the acid and
bicarb inlet tubing! If air is seen check the connector(s).
