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 bae (53).
2. Clean or replace filter element when dirty,
when optional mechanical service life
indicator shows approximately all red, or
when optional electrical service life indicator
provides an electrical output.
DIASSEMBLY
1. Shut o inlet pressure. Reduce pressure in
inlet andoutlet 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 (59), as it is cemented
to body.
CLEANING
1. Clean lens (3, 24, 35) with warm water only.
Do not submerge electrical service indicator

(6) in water. Clean indicator (6) with dry, clean
cloth. Clean other parts with warm water and
soap.
2. Rinse and dry parts. Blow out internal
passages in body (14) with clean, dry
compressed air. Blow air through filter
element (55) from inside to outside to remove
surface contaminants.
3. Inspect parts. Replace those found to be
damaged.
ASSEMBLY
1. Lubricate o-rings, the portion manual drain
body (43) that contacts the bowl, and the
hole in the manual drain body that accom
modates the stem of drain valve (41) with
o-ring grease.
2. Assemble the unit as shown on the exploded
view.
3. Assemble the liquid indicator parts (19 thru
26, 30 thru 37) to reservoir. Apply a 0.9 to
1.8 kg (2 to 4 pound) clamping force to upper
and lower sight glass brackets (20, 31).
Tighten screws (19, 30).
4. Arrows on indicator (3, 8) and body (14) must
point in same direction.
5. Torque Table

6. Turn bowl into body until arrowhead on bowl
is aligned with or to the right of the arrowhead
on the body.
WARNING
These products are intended for use in industrial
compressed air systems only. Do not use these
products where pressures and temperatures can
exceed those listed under Technical Data.
Polycarbonate plastic bowls can be damaged
and possibly burst if exposed to such
substances as certain solvents, strong
alkalies, compressor oils containing ester-based
additives or synthetic oils. Fumes of these
substances in contact with the polycarbonate
bowl, externally or internally, can also result in
damage. Clean with warm water only.
Use metal bowl in applications where a plastic
bowl might be exposed to substances that are
incompatible with polycarbonate.
Before using these products with fluids other
than air, for non industrial applications, or for
life-support systems consult Norgren.
Use in potentially explosive atmospheres

• Only non-flammable gasese to be used as a
medium.
• Surface temperature dependant on process
fluid temperature and ambient temperature -
must be below the ignition temperature of the
flammable gas or dust.
• Earth unit and/or pipework to avoid
electrostatic discharge.
• Precautions should be taken to prevent hazard
from adiabatic compression.
• Use wet cloth for cleaning.
• Protect the unit from object falling onto it.
• Avoid contact with corrosive environment.
• For servicing the unit it is recommended to
carry out this work outside of the danger
zone.
• For details of ignition hazard assessment
contact Norgren.
