3. In the case of a type with auto drain
• The auto drain operates when the drainage level reaches the
top of the sight glass, and the drain will be discharged.
• When using the AFF2C to 22C, 37B, AM 150C to 550C,
650 with auto drain, the drain is automatically discharged
with the knob tightened to the “S” side. Manual drain dis-
charge, however, is also possible.
<Manual operation>
A manual knob attached to the auto drain end is tightened to
the “S” side in normal operation. The drain can be discharged
by loosening it to the “O” side. (Be careful, however, if pres-
sure remains inside the filter when the drain is discharged, the
drain will blow out from the drain port.)
4. The drain exhaust parts replacement method and
necessary parts are different depending on when it
was manufactured.
