10.11. Adjustment of bypass flow rate
During V9 is OFF (that is, dialysate line is bypassed), adjust dialysate flow rate by turning adjusting
screw of pinch cock 1 (PC1) under monitoring flow rate indication of flow meter based on the
following procedures.
(1) Remove left cover form lower part of machine to expose PC1.
(2) Turn on power SW of machine.
(3) Turn on [DIALYSIS] SW to shift to dialysis wait process.
(4) Press [PREP.] SW to shift to preparation process. Engage coupler with bypass connector. If
dialysate concentrate is not used, connect dummy resistor to conductivity sensor.
(5) Check stabilization of dialysate temperature and concentration.
(6) Check that [BYPASS] SW is OFF (released bypassing and dialysate flow through coupler
line).
(7) Adjust dialysate flow rate to 500ml/min by turning adjusting screw of NV2 under monitoring
dialysate flow rate indication of flow meter.
(8) Turn on [BYPASS] SW to bypass dialysate line.
(9) Adjust bypass flow rate to 500ml/min by turning adjusting screw of PC1 under monitoring
bypass flow rate indication of flow meter. Tube should be centered at PC1 and plates of PC1
should be aligned correctly.

(10) Turn off [BYPASS] SW and wait for 1 to 2 minutes.
(11) Turn on and off [BYPASS] SW several times to check that dialysate flow rate is 500ml/min
when bypassed and not bypassed.
(12) Apply adhesive or the like to adjusting screw of PC1 for fixing.
(13) Return the removed cover to the original position.
