When mounting the bracket or tightening the hexagon panel nut on the panel, tighten them to
the recommended tightening torque.
Insufficient tightening torque can cause loose piping. Excessive tightening torque can cause thread
damage.
Recommended tightening torque [N-m]
Set nut (for bracket)
1.8 to 2.2
Hexagon panel net (handle type only)
3 to 4

Adjust the pressure by increasing the pressure. After pressure adjustment, be sure to tighten the
lock nut. When tightening the nut, tighten so that the handle does not move due to friction caused
by tightening.
The outlet pressure may become lower than set pressure if adjusted by decreasing the pressure. Turning the handle
clockwise increases the outlet pressure, and turning it counterclockwise reduces the pressure.

When pressure is applied to the inlet of a regulator, make sure that the outlet port is connected
to the circuit. Air blow occurs from the outlet and it depends on the operating conditions.

The set pressure may vary depending on the elapsed time and change in ambient temperature
after pressure setting. If the setting value varies, adjust with the handle.

If the directional control valve (solenoid valve, mechanical valve etc.) is mounted and ON-OFF
is repeated for a long time, the set pressure may vary. If the setting value varies, adjust with
the handle.

There may be pulsation or noise depending on the pressure conditions, piping conditions and
ambient environment. In this case, it is possible to improve the problem by changing the
pressure conditions and piping conditions.
If the problem is not improved, contact your SMC sales representative.

There is no connection thread on the exhaust port. If it is necessary to mount a silencer to the
exhaust port, please contact your SMC sales representative.

When a pressure gauge is mounted to the regulator, please do not exceed the maximum
display pressure. It may lead to a malfunction.

A safety device needs to be installed if output pressure is exceeding the set pressure,
otherwise this can cause the breakage of outlet device and equipment or malfunction.
