！ Warning
1. Warning concerning abnormal outlet pressure
 If there is a likelihood of causing an outlet pressure drop due to unforeseen circumstances
such as equipment malfunction, thus leading to a major problem, take safety measures on
the system side.
 Because the outlet pressure could exceed its set range if there is a large fluctuation in the
inlet pressure, leading to unexpected accidents, take safety measures against abnormal
pressures.
 Operate the equipment within its maximum operating pressure and set pressure range.
2. Residual pressure measures
 To quickly exhaust residual pressure downstream of the booster regulator for maintenance,
mount a 3-port valve to the outlet of the booster regulator (Refer to the figure below).
though the 3-port valve is connected to the IN side for exhausting the residual pressure,
the check valve in the booster regulator will operate, which interferes with exhausting
the residual pressure on the outlet side.
 After exhausting the residual pressure on the outlet side, ensure that the supply pressure
is also exhausted. Exhausting the supply pressure will stop the operation, which prevents
unnecessary air consumption from occurring.
