Warnings
1. Avoid tensile strength or moment load on the product body and the fitting cartridge. It may damage the product.
2. Carry out the maintenance of filter element periodically. There is a possibility of dropping the performance or causing troubles by clogging
of the filter element. Before replacing the filter element, make sure to read "How to remove the dust in bowl and replace a filter element"
carefully, release pressure and remain atmospheric pressure condition in the filter.
3. This product is not designed to be explosion-proof. Do not apply any positive pressure except momentary pressure for blow-off. It may
cause damage to the product and cause injury.
4. Bowl material is polycarbonate. Avoid chemicals or atmosphere with chemicals listed in the table-1 below.The bowl may get broken and
injure human body.

*There is some possibilities that other chemicals not listed in the table above may not be used. Please make sure to carry out sufficient
evaluation before use.
Cautions
1. Rust and foreign substances in a piping may cause damage, malfunction or performance drop of the product. Flushing before use and
periodic flushing of a piping are recommended. Flushing on a fitting type filter shall be done with a stem or short cut tube inserted into a
fitting. Sealing parts in the fitting may fly out of it.
2. Check the arrow ▷ (IN → OUT) marking on a filter before installing. Installation with a wrong direction does not fulfill the filter performance.
3. Lock the bowl properly and make sure that there is no vacuum leakage after removing dust or replacing a filter element.
4. Keep dust particles or drain water in a bowl lower than "MAX. DRAIN LEVEL" marking on it. Airflow may fling up the dust in the bowl,
causing a significant reduction of the filter element lifetime.
5. Hold a hex. part on each port by a spanner wrench, when connecting a fitting with male thread, to prevent co-rotation of each port. Refer
to the tightening torque in the Table-2.

6. Install or fix the product with its bowl facing down and vertically.
7. Re-torque the bracket fixing screws periodically.
