Mounting
Warning
1. Mount and operate the product after reading the manual carefully and understanding its
contents. Also, keep the manual in a place where it can be referred to as necessary.
2.
Install with enough space around the regulator to perform regular maintenance and operation.
Refer to section [10.Dimensions] (p. 22) for necessary space.
3. Do not drop or apply impact during transportation or installation. Damage of products or
pressure gauge can result in malfunction.
4.
Do not install in areas with high humidity or high temperature. It may lead to a malfunction of the
pressure gauge.
5. If air leakage increases or equipment does not operate properly, stop operation. After mounting
or maintenance, etc., connect the compressed air and power supplies, and perform appropriate
function and leakage tests to confirm that the unit is mounted properly.
Adjustment
Warning
1. Adjust the set pressure ensuring correct inlet and outlet pressures. Turning the knob
excessively can cause damage to the internal parts.
2.
Do not use tools on the pressure regulator knob as this may cause damage. It must be operated
manually.
Caution
3. For the product with a pressure gauge, do not apply pressure exceeding the maximum
scale of the pressure gauge in order to protect the gauge.
4. When setting the pressure, the inlet pressure must be supplied after the pilot valve is
powered.
5. Adjust the pressure whilst the pressure is increasing. Pressure may become lower than
the set pressure if adjusted by decreasing the value. Rotate the knob clockwise to
increase the set pressure. Counterclockwise to decrease the pressure. Moreover,
please lock the knob after setting pressure.
6. For the regulator with backflow function, upstream pressure needs to be higher than
downstream pressure by 0.05 MPa or more.
7. Outlet pressure may rise when the inlet pressure is discharged and resupplied after
pressure setting. In this case, consume air at the outlet which will bring the pressure
closer to the set pressure.
8. Outlet pressure may change if the product is used for a long period of time. Please
confirm the set pressure regularly.
9. When pressure difference between the inlet side and the outlet side is large, chattering
may occur. In that case, please reduce the pressure difference between the inlet and
the outlet. Please consult SMC it chattering continues.
