F- 11.0.7 CHECK FOR SECONDARY SIDE RESTRICTION

a) Obtain a 1000 ml graduated cylinder.
b) Plug the red concentrate connector into its rinse port.
c) Turn the machine on but DO NOT press any keys! "Select Program" remains up till instructed
otherwise!
d) Remove the red dialyzer connector from the shunt door and place it into a 1000 ml graduated cylinder.
e) Plug valve #37 into valve #30's distribution board position "V30". This opens valve #37. Valve #30
remains unplugged!
f) With "Select Program" up, measure flow, from the dialyzer connector, for one (1) minute. If no flow,
double check valve connector placement. TWO (2) possible scenarios based on measured flow:
1) IF (and ONLY if) less than 800 ml collected: A) Return the dialyzer connector to the shunt but
DO NOT
unplug valve #37; B) See (ABOVE) procedure number
2) IF 800 ml or more collected: See parts a THROUGH d below:
a) Turn the machine OFF!
b) Return valves #37 and #30 to their distribution board positions.
c) Turn the machine on and return to Dialysis Program ("Select Program" → 'Dialysis' →
'CONFIRM')!
d) Call debug screen 0. Watch Flow Error for six (6) minutes OR until it EVER = 1! TWO (2)
possible scenarios:
1) IF Flow Error EVER = 1: TWO (2) possible bad components: 1) DiaSafe
2) transducer #10*. *To LOCATE the CFS transducer refer to
2) IF Flow Error ALWAYS = 0. The flow error is not occuring at this time!
