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 possible 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 tube.
8. Install a Norgren general purpose filter with a
5 µm element upstream of the oil removal
filter to obtain maximum element service life.
Servicing
1.Open manual drain to expel accumulated
liquids. Keep liquids below element (53).
2. Replace filter element when pressure drop
across element exceeds 0,7 bar (10 psig).
The mechanical service life indicator shows
approximately all red and the optional
electrical service life indicator provides an
electrical output when pressure drop across
the element reaches 0,7 bar (10 psig)
Diassembly
1. Shut off inlet pressure. Reduce pressure in
inlet and outlet lines to zero.
2. Unscrew the clamp ring and remove filter
from yoke.
3. Disassemble in general accordance with the
item numbers on exploded view. Do not
remove the drains
or the service indicators unless replacement
is necessary. Remove and replace only if they
malfunction. Do not attempt to remove rod
(54), as it is cemented to body.
