4 Settings
•
The outlet pressure is set by rotating the adjusting bolt, at the bottom of
the regulator. SeeFigure 3.Loosen the locknut first.
•
The adjusting bolt (32 mm across flats) can be rotated by a spanner,
or with a screwdriver using the Ø11mm hole in the bolt head.
Warning
•
Adjust the outlet pressure while confirming the pressure gauge values on
the inlet and outlet sides.
•
Over-rotating the adjusting bolt will damage the inner components of the
product.
•
The set outlet pressure should be less than 85% of the inlet pressure.
•
Setting the outlet pressure to more than 85% of the inlet pressure may
cause fluctuation of flow or pressure on the inlet side, resulting in
unstable operation.
•
The maximum value of the set pressure range has a tolerance,
therefore, the set pressure may exceed this value.
•
Tighten the locknut when adjustment is complete. The locknut is not
an anti-tamper device. Appropriate measures against foreseeable
misuse must be taken if this can cause a hazard.
Caution
•
Adjust after carefully confirming the inlet pressure.
•
When adjusting the outlet pressure, a torque is applied to the adjusting
bolt. Support the product separately, so that the torque force is not
transferred to the external piping.

•
Setting the outlet pressure should be conducted by increasing the
pressure.
•
Setting the outlet pressure by decreasing the pressure may result in
going below the required set pressure.
•
Turning the adjusting bolt in the clockwise direction, increases the
pressure.
•
Turning the adjusting bolt counter-clockwise, will decrease the outlet
pressure.

7 Maintenance
7.1 General Maintenance
•
This product does not require maintenance. However the following
advice should be followed:
Ensure the proper function of the regulator is regularly
checked
Ensure there is no build-up of dirt or debris on the regulator,
especially around the vent ports and adjustment screw.
Caution
•
Not following proper maintenance procedures could cause the product to
malfunction and lead to equipment damage.
•
If handled improperly, compressed air can be dangerous. Maintenance
of pneumatic systems should be performed only by qualified personnel.
•
Before performing maintenance, turn off the power supply and be sure to
cut off the supply pressure. Confirm that the air is released to
atmosphere.
•
After installation and maintenance, apply operating pressure and power
to the equipment and perform appropriate functional and leakage tests
to make sure the equipment is installed correctly.
•
Do not make any modification to the product.
•
Do not disassemble the product, unless required by installation or
maintenance instructions.
8 Limitations of Use
Warning
•
This product must not be used as a safety accessory as defined by the
Pressure Equipment Directive 97/23/EC.
•
Install a protective device if the outlet pressure exceeding the set outlet
pressure could cause equipment damage or malfunction.
•
The outlet pressure may fluctuate when the air has not been consumed
for a long time, or the product is used in a shut-off or balancing circuit on
the outlet side.
•
Grease may leak into the outlet side, as it is applied to inner sliding parts
and seals.
•
Do not use in circuits requiring highly precise relief sensitivity or setting
precision.
