Warning
Installation location
- Please install the product in a location where pulsation is unlikely to occur.
When the difference between the inlet and outlet sides exceeds 0.1MPa, the element
might be broken.
- Install so that reverse pressure and back flow will not be generated.
Otherwise, the element might be broken.
Piping
- Connect piping/fittings using the recommended torque while holding the product
tightly.
Insufficient tightening torque can cause loose piping or sealing failure.
Excessive tightening torque can cause thread damage.
If the female side is not held while tightening, excessive force will be applied to the bracket
directly, causing breakage.
- Avoid excessive torsional moment or bending moment other than those caused by the
equipment's own weight as this can cause damage. External piping needs to be supported
separately.
Piping materials without flexibility such as steel tube piping are prone to be effected by
excess moment load and vibration from the piping side. Use flexible tubing in between to
avoid such an effect.
As a filter is a heavy object, please transfer or install it making sure that it will not be
dropped or dented.
Caution
Installation location
When installing, allow sufficient space for maintenance. (Refer to Dimension diagram
on P.19.)
- The piping of this product should be horizontal (drain exhaust should vertically face
downwards.)
If it is mounted inclined, laterally or upward/downward, the separated drainage will be
splashed over the outlet.
It may cause the operation failure of the auto drain.
- Pay attention to the dust generated from the air equipment which is mounted on the
outlet.
If the air equipment is mounted on the outlet of the filter, dust will be generated from the
equipment and cleanliness of the compressed air might be reduced. Consider the
mounting position of the air equipment in accordance with the required cleanliness of the
compressed air.
