F- 7.0.4 Flow Error = 1/Isolate 'Fresh Side' Flow Paths - Fresenius Medical Care 2008K2 Troubleshooting Manual

F- 7.0.4 FLOW ERROR = 1 / ISOLATE 'FRESH SIDE' FLOW PATHS
Plug the acid connector into its rinse port to call
a)
the "Select Program" screen but DO NOT press
any keys!
b) Balancing Chamber valve connectors will be switched to test 'fresh side' flow paths. Flow is measured
into a 1000 ml GRADUATED cylinder for one (1) minute. Good flow = more than 800 ml every minute!
c) ENSURING "Select Program" REMAINS up, perform PARTS 1 AND 2 EVEN IF PART 1 yields bad
flow!
PART 1:
a) Remove the RED DIALYZER connector from the shunt door and place it into a bucket!
P
b) lug valve #35's connector into valve #30's distribution board position, "V30". Leave
valve #30 unplugged!
c) Hold the dialyzer connector up and watch flow (if any) for one (1) minute. If good initially
but significantly slows indicates an intermittent bad valve #31 or #35. If no flow, ENSURE
valve #35's connector is placed properly in position "V30". If okay see part d!
d) Measure flow, from the dialyzer connector, into the cylinder, for one (1) minute.
Return valve #35's connector to its distribution board position!
e)
f) Record Part 1's measurement
PART 2: P
a) lug valve #37's connector into valve #30's distribution board position, "V30".
b) Hold the dialyzer connector up and watch flow (if any) for one (1) minute. If good initially
but significantly slows indicates a bad valve #33 or #37. If no flow, ENSURE valve
#37's connector is placed properly in position "V30". If okay see part d.
c) Measure flow, from the dialyzer connector, into the cylinder, for one (1) minute!
d) Return the connector to the shunt door.
e) Leaving valve #37 in valve #30's position for now, analyze BOTH Part 1 AND Part 2's
measurements per
Table 2 – Parts 1 AND 2
PART 1's
measurement
Less than 800 ml
