No spitting! There is a problem with the Acid Pump!
CO- 1.0.3.6.3 ACID PUMP SPITTING = IT PRIMED
A) Remove the clamp and reattach the Acid Pump’s output tubing.
B) Connect to the jugs and return to Dialysis Program (“Select
Program” → ‘Dialysis’ → ‘Enter’).
C) Set [Dialysate Flow] to 800 ml/min then allow one (1) minute
D) Call debug screen 0. Figure right, based on Valve #105’s dot color:
1) IF WHITE: See procedure number CO- 1.0.3.6.4 (page 349).
2) IF REMAINING BLUE: Check through the Acid Inlet tubing. If acid is drawn, in one direction only,
towards the machine, return to (ABOVE) procedure number CO- 1.0.3.1 (page 340). If acid is NOT
being drawn there is a problem with the Acid Pump.
CO- 1.0.3.6.4 VALVE #105’S ‘DOT’ IS WHITE
A) Return to Service Mode.
B) Press the Service Mode screen’s ‘Options’ button.
C) Call debug screen 0 and ENSURE Valve #105’s ‘dot’ is now blue!
E) Call debug screen 15 to see Acid Press:
1) IF (and ONLY if) a negative sign (-) appears: Attach a syringe, with its plunger pulled out, to
the RED connector, then push on the plunger attempting to create at least positive 90.
2) IF a negative sign (-) DOES NOT appear: Attach a syringe, with its plunger pushed all the way
in, to the RED connector, then pull on the plunger attempting to create at least negative (-)90
F) Are you able to make Acid Press at least positive OR negative (-)90?
Yes Acid Press goes to at least positive 90 OR negative (-)90! There may still be a problem
with the Acid Pump.
No Could not make Acid Press positive 90 OR negative (-)90! FOUR (4) possible problems:
1) Loose bibag Interface Board ribbon cable (refer to Figure 4C (page 11)) OR; 2) Bad
Pressure Sensor #106 OR; 3) Bad bibag Interface Board OR; 4) Bad connection, from
Pressure Sensor #106, inside the Distribution Box 2 (refer to Figure 4D (page 13)).
