10.8-1
10.8. Adjustment of priming end pressure
Adjust priming end pressure by checking pressure at priming end by turning relief valve 1 based on
the following procedures.
(1) Required devices
Manometer (calibrated)
Connection means (tubes and T-pipe)
Forceps
Monkey wrench
(2) Remove right cover from lower part of machine to expose relief valve 1.
(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 V11 using forceps and disconnect silicone tube from V11 to
connect it to manometer through connection means.

(8) After lifting manometer sufficiently, release the clamping followed by lowering it to align with
chamber horizontally.
(9) Check visually water discharge from machine and set the manometer indication to 0.0932 to
0.0981 MPa (698 to 735mmHg / 0.95 to 1.00kgf/cm
2
) during stop of the discharge by
loosening set nut of relief valve 1 followed by turning the valve. Take care for silicone tube not
to be twisted.
(10) Tighten the set nut. This may cause small change of the set value. Check the value again.
Adjusting value
Priming end pressure 0.0932 to 0.0981 MPa (698 to 735mmHg / 0.95 to 1.00kgf/cm

)
(11) Remove the manometer and the connection means to return to the original condition.
(12) Return the removed cover to the original position.
