Installation & Maintenance
Instructions
DISASSEMBLY
1. Filter can be disassembled without removal from air line.
2. Shut off inlet pressure. Reduce pressure in inlet and outlet
lines to zero.
3. Disassemble in general accordance with the item numbers
on exploded view. Do not remove the drains or the service
indicators (1, 6) unless replacement is necessary. Remove
and replace only if they malfunction.
CLEANING
1. Clean mechanical indicator lens (3) with warm water only.
Clean electrical 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 (17) from inside to outside to remove surface
contaminants.
3. Inspect parts. Replace those found to be damaged.
ASSEMBLY
1. Lubricate o-rings with o-ring grease.
2. Bowl Assembly (Current and 1996 Bowls)
If the 1/4 turn manual drain was removed, lubricate the
portion of the drain body (21, 34) that contacts the bowl,
and the hole in the manual drain body that accommodates
the stem of drain valve (22, 35) with o-ring grease. Press
body (21, 34) thru hole from inside of bowl. Place retainer
o-ring (23, 36) over body (21, 34) and position in groove.
Press drain valve (22, 35) thru hole in body (21, 34).
Assemble the liquid indicator parts to bowl as shown on
the exploded view. Tighten screws (27, 40) to
1,7 to 3,4 N-m (15 to 30 inch-pounds).
3. Bowl Assembly (1990 - 1995 Bowl)
Tighten drain nut (55, 59) to 2,3 to 2,8 N-m (20 to 25 inch-
pounds). Assemble the liquid indicator parts (47 thru 51)
to bowl. Apply a 0,9 to 1,8 kg (2 to 4 pound) clamping
force to upper and lower brackets (48) to pull brackets
together. Tighten screws (47) to 0,9 to 1,1 N-m (8 to 10
inch-pounds).
4. Bowl Assembly (Bowl Prior to 1990)
Tighten drain nut (63, 67) to 2,3 to 2,8 N-m (20 to 25 inch-
pounds). Assemble the liquid indicator parts to bowl as
shown on the exploded view. Tighten retainer (69) to
1,1 to 1,7 N-m (10 to 15 inch-pounds).
5. Lubricate male threads on metal bowl (53, 74) and
intermediate body (15, 15A) with a small amount of anti-
seize compound.
6. Assemble filter as shown on the exploded view. Arrows on
indicator (3, 8) and body (14) must point in same
direction. Tighten screws (2, 7) to 2,8 to 3,9 N-m
(25 to 35 inch-pounds). Install element (17) with the larger
end against end cap gasket (18). Tighten end cap (19) to
7,9 to 8,5 N-m (70 to 75 inch-pounds). Tighten
intermediate body (15, 15A) to approximately
16 N-m (12 foot-pounds) - snug with two hands.
7. Bowl Installation (Current and 1996 Bowls)
Push bowl assembly (20, 33) into intermediate body and
turn fully clockwise.
8. Bowl Installation (All Bowls Prior to 1996)
Turn bowl assembly (46, 61) fully into intermediate body,
approximately five full turns. Unscrew bowl no more than
one full turn to position liquid level lens for best visibility.
CAUTION
Water vapor will pass through these units and could
condense into liquid form downstream as air temperature
drops. Install an air dryer if water condensation could have a
detrimental effect on the application.
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.
Before using these products with fluids other than air, for
nonindustrial applications, or for life-support systems consult
Norgren.

INSTALLATION
1. Shut-off air pressure. Install filter in air line -
● vertically (bowl down),
● with air flow in direction of arrow on body,
● upstream of regulators, lubricators, and cycling
valves,
● as close as possible to the air supply when used as a
main line filter,
● as close as possible to the device being serviced
when used as a final filter.
2. Connect piping to proper ports using pipe thread sealant
on male threads only. Do not allow sealant to enter
interior of unit.
3. Before applying air pressure, make sure bowls (32, 45,
53, 74) are turned fully into intermediate body (15, 15A).
See steps 7 and 8 of ASSEMBLY.
4. Flexible tube with 3mm (0.125") minimum I.D. can be
connected to the automatic drain. Avoid restrictions in
the tube.
SERVICING
1. Open manual drain to expel accumulated liquids. Keep
liquids below top of liquid level lens.
2. Clean or replace filter element when pressure drop
across element exceeds 0,7 bar (10 psig). Optional
mechanical service indicator shows approximately all red
and optional electrical service indicator provides an
electrical output when pressure drop reaches 0,7 bar (10
psig).
