10.9. Adjustment of closed circuit pressure
Adjust closed circuit pressure based on the following procedures.
(1) Required devices
Blood line
Dialyzer
(2) Remove left cover from lower part of machine to expose relief valve 2.
(3) Turn on power SW of machine.
(4) Turn on [DIALYSIS] SW to shift to dialysis wait process.
(5) Connect concentrate to machine.
(6) Press [PREP.] SW to shift to preparation process.
(7) Set dialyzer and blood line to machine.
(8) Check stabilization of dialysate temperature and conductivity and release of bypassing.
(9) Full open NV2 to run dialysate at the maximum flow rate.
(10) Adjust blood pump flow rate so that dialysate pressure becomes 0mmHg.
(11) Loosen set nut of relief valve 2 and turn the valve body to adjust dialysate flow rate indicated
by flow mater to 600mL/min. Take care for silicone tube not to be twisted.
(12) Tighten the set nut. This may cause small change of the dialysate flow rate. Check the flow
rate again.
(13) Turn NV2 to adjust dialysate flow rate to 500mL/min.
(14) Return the removed cover to the original position.
NOTE
z Check the upper edge of float when dialysate flow adjustment.
