10.7 Adjustment of reducing valve
Adjust actuating pressure of reducing valve by turning adjusting screw of the valve by measuring
manometer pressure after priming completion based on the following procedures.
(1) Required devices
Manometer (calibrated)
Connection means (tubes and T-pipe)
Forceps
(2) Remove right cover form lower part of machine to expose reducing valve.
(3) Turn on power SW of machine.
(4) Turn on [DIALYSIS] SW to shift to dialysis wait process.
(5) Press [PREP.] SW to shift to preparation process. Water may be used instead of concentrate.
(6) Check water temperature stabilization.
(7) Clamp tube connected to IN of valve V10 using forceps and disconnect silicone tube from the
valve to connect it to manometer through connection means.

(8) After lifting manometer sufficiently, release the clamping followed by lowering it to align with
reducing valve horizontally.
(9) Check visually water discharge from machine and set the manometer indication to 0.0333 to
0.0363 MPa (250 to 270mmHg / 0.34 to 0.37kgf/cm
2
) during stop of the discharge by
loosening set nut followed by turning adjusting screw of reducing valve.
