F- 7.0.4 FLOW ERROR = 1 / ISOLATE ‘FRESH SIDE’ FLOW PATHS
a) Plug the red concentrate connector into its rinse
port to call 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!
b) Plug valve #35’s connector into valve #30’s distribution board position, “V30”. Leave
valve #30 unplugged!
c) Hold the connector over the bucket 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 RED connector, into the cylinder for one (1) minute.
e) Return valve #35’s connector to its distribution board position!
f) Record Part 1’s measurement
THEN perform PART 2!
PART 2: a) Return the dialyzer connector to the bucket.
b)
Plug valve #37’s connector into valve #30’s position, “V30”.
c) Watch flow (if any) from the connector 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.
d) Measure flow, from the RED connector, into the cylinder, for one (1) minute!
e) Return the connector to the shunt door.
f) Leaving valve #37 in valve #30’s position for now, analyze BOTH Part 1 AND Part 2’s
measurements per Table 3 below:
