CAUTION: To set the safety valve to 20 MPa or higher pressure, caution is required.
(Excessively increasing the safety valve setting causes the pump to be damaged by surge
pressure.)
To adjust the safety valve, follow the procedure below:
First, set the safety valve by following the above steps [1] to [5] so that the pressure setting is
7.7 MPa (corresponding to one turn of the pressure adjusting screw) lower than a target pressure.
Then, tighten the adjusting screw by turning it clockwise by one turn, and conduct the above
step [7].
