Clean- 4.6.1 Both Pdia And Adia Are Good - Fresenius Medical Care 2008K2 Troubleshooting Manual

CLEAN- 4.6.1 BOTH PDIA AND ADIA ARE GOOD

a) Return the dialyzer connector to the shunt and close the door!
b) Press 'CONFIRM' then
c) To isolate between four (4) possible bad valves read part d's two-part description BEFORE performing
part e!
d) Return to debug screen 4. PDIA NORMALLY behaves as follows:
PART 1: When Valve #43 is closed* PDIA cycles between 0.0 (for 3 to 5 seconds) to more than 0.1
(for about one second). It is abnormal for PDIA to cycle to 6.0 or more OR remain 0.0 for more than
seven (7) seconds!
* Valve #43 cycles between closed for forty five (45) seconds and open for sixteen (16) seconds
PART 2: When Valve #43 is open* PDIA stays between 1.0 and 5.0. When Valve #43 closes PDIA
resumes cycling. If (and ONLY if) PDIA REMAINS between 1.0 and 5.0 for MORE THAN ninety (90)
seconds see procedure number
e) WITHOUT LOOKING AWAY, watch PDIA AND for "Flow Recirc Error 1" for five (5) minutes OR until if
"Flow Recirc Error 1" appears. Proceed according to one of the TWO (2) possible scenarios below:
1) IF (and ONLY if) "Flow Recirc Error 1" NEVER occurs: Whatever was causing the Flow Error
is not exhibiting yet! Watch PDIA until either a Flow Error occurs OR Heat Disinfect finishes.
2) IF "Flow Recirc Error 1" occurs AND also one of THREE (3) scenarios below:
Scenario #1: IF (and ONLY if) PDIA was EVER = 6.0 OR more: A restriction at Valve #24 OR
Valve #25 is indicated. See the Figures below to locate these valves!
Scenario #2: IF (and ONLY if) PDIA EVER stayed 0.0 for longer than seven (7) seconds: A
restriction at Valve #29 is indicated! See the left Figure below to locate Valve #29!
Scenario #3: IF PDIA NEVER = 6.0 OR more AND NEVER 0.0 more than seven (7) seconds:
To isolate Valve #43, proceed to
return to HEAT DISINFECT!
