Installation
1. Install yoke in air line - with air flow in direction
of arrow on top of yoke, upstream of
regulators, lubricators, and cycling valves, as
close as possible to the air supply when
filter is used as a main line filter, as close as
posible to the device being serviced when
filter is used as a final filter.
2. Connect piping to yoke ports using pipe
thread sealant on male threads only.
3. Lubricate o-rings (15) with a light coat of
o-ring grease, then place o-rings in grooves in
body (14).
4. Place clamp ring under lugs on top of yoke.
5. Make sure arrows on yoke and filter point in
same direction, then plug filter into yoke and
tighten clamp ring hand tight.
6. Turn bowl into body until arrowhead on bowl
is aligned with or to the right of the arrowhead
on the body.
7. Flexible tube with 3mm (0.125") minimum I.D.
can be connected to the automatic drain.
Avoid restrictions in the
Servicing
1. Open manual drain to expel accumulated
liquids. Keep liquids below baffle (53).
2. Clean or replace filter element when dirty,
when optional mechanical service life
indicator shows approximately all red, or
4380-300 when optional electrical service life indicator
provides an electrical output.
4380-060 Diassembly
1. Shut off inlet pressure. Reduce pressure in
4380-061 inlet andoutlet lines to zero.
2. Unscrew the clamp ring and remove filter
5576-97 from yoke.
3. Disassemble in general accordance with the
5576-98 item numbers on exploded view. Do not
remove the drains or the service indicators
5576-99 unless replacement is necessary. Remove
and replace only if they malfunction. Do not
attempt to remove rod (59), as it is cemented
to body.
