BC LEAK- 3.0.0 DIAPHRAM LEAK TEST
Two (2) buckets are required, one empty and the other filled with one gallon of ACID CONCENTRATE. Place
both buckets on the floor and read the procedures before continuing:
a) Place the machine into RINSE. If the external flow indicator’s ‘bob’ is not moving up and down
these tests are invalid!
b) Call debug screen 5. Allow FPRE (middle column, ABOVE FPOS), to become less than two thousand
eight hundred (2800). This verifies all conductive fluids have been rinsed out.
c) ENSURING RINSE is running (Remaining Time is NOT = 0:00) open the shunt door.
d) NOTE FPOS! Typically between 2000 and 4000.
e) Per the Figure right, direct the Ultrafiltrate Output Sample
Connector into the EMPTY BUCKET to prevent excessive
UF circuit pressure.
f)
Per the Figure below, TIGHTLY clamp the
tubing at Valve #29’s. Ignore Flow Errors for
now!
g) Remove the blue dialyzer connector from the shunt door and place it into the empty bucket.
h) Place the red dialyzer connector into the bucket of acid concentrate but
DO NOT close the shunt door!
Rinse must NOT interrupt! The blue connector MUST be delivering water into its bucket!
i) WITHOUT LOOKING AWAY, watch FPOS for up to 45 seconds. Does it EVER, even if only once,
increase or fluctuate to more than seven thousand (7000)?
