Cautions
Warnings
1. Rust and foreign substances in a piping may cause damage, malfunction or performance drop of the product. Flushing before use and
periodic ushing of a piping are recommended. Flushing on a tting type lter shall be done with a stem or short cut tube inserted into a
tting. Sealing parts in the tting may y out of it.
2. Check the arrow▷(IN→OUT) marking on a lter before installing. Installation with a wrong direction does not fulll the lter performance.
3. Lock the bowl properly and make sure that there is no vacuum leakage after removing dust or replacing a lter element.
4. Keep dust particles or drain water in a bowl lower than “MAX. DRAIN LEVEL” marking on it. Airow may ing up the dust in the bowl,
causing a signicant reduction of the lter element lifetime.
5. Hold a hex. part on each port by a spanner wrench, when connecting a tting with male thread, to prevent co-rotation of each port. Refer
to the tightening torque in the Table-2.
Table-2. Tightening torque (Reference)
Thread type Thread size Tightening torque
Taper pipe
thread
R3/8 12.5~14.5N·m
R1/2 20~22N·m
R3/4 30~35N·m
Parallel pipe
thread
G3/8 Follow the tightening torque of
male thread.
G1/2
G3/4
6. Install or x the product with its bowl facing down and vertically.
7. Re-torque the bracket xing screws periodically.
1. Avoid tensile strength or moment load on the product body and the tting cartridge. It may damage the product.
2. Carry out the maintenance of lter element periodically. There is a possibility of dropping the performance or causing troubles by clogging
of the lter element. Before replacing the lter element, make sure to read “How to remove the dust in bowl and replace a lter element”
carefully, release pressure and remain atmospheric pressure condition in the lter.
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.
