BC LEAK- 1.2.0 CHECK FLOW PUMP RELIEF VALVES #78
This is not a routine calibration. Follow the procedure below to avoid error!
a) Enter Service Mode
b) Press the 'CONFIRM' key to start the flow pump. Assure its running counterclockwise!
c) Without adjusting valve #78, is pressure reaching

Yes a) NOTE: If the adjustment screw had to be turned in fully clockwise so that its threads are
not visible three possibilities: 1) Bad flow pump #21; 2) Bad flow pump motor (possibly
bad brushes); 3) Bad Flow Relief Valve #78.
b) Repeat procedure number
possibilities: 1) Bad flow pump #21; 2) Bad flow pump motor (possibly bad brushes).

3) Bad Flow Relief Valve #78
BC LEAK- 2.0.0 DIAPHRAGM LEAK TEST
NOTE: Two buckets are required, one empty and the other filled with one gallon of pure acid concentrate.
Read the procedure before continuing:
a) Call debug screen 5 and allow FPRE and Pre Offset to get within +/- 100 of
each other (approximately 2300). This verifies that all conductive fluids have
been rinsed out.
b) Pull the red concentrate connector from its port to "Interrupt" Rinse then plug it back in and return to
Rinse.
c) Direct the UF sample connector tubing into the empty bucket to prevent pressure buildup.
IMPORTANT! Referring to
d)
clear tubing at valve #29's input nozzle. Ignore Flow Errors for now!
e) Open the shunt door and place the blue dialyzer quick connectors into the empty bucket.
f) Place the red dialyzer connector into the bucket of pure acid concentrate and assure it remains
submersed.
IMPORTANT!
g) Do NOT shut the shunt door! The Rinse program must NOT interrupt!
h) Watch FPRE CAREFULLY for three minutes. Does it increase (or fluctuate) to 3000 or greater at ANY
time?
Yes A torn balancing chamber diaphragm is indicated. Remove the clamp from valve #29 then
replace both balancing chamber diaphragms.
