ADJUSTMENT
1. Before applying inlet pressure to filter/regulator, turn
adjustment (2 or 5A) counterclockwise to remove all force
on regulating spring (6).
2. Apply inlet pressure, then turn adjustment (2 or 5A)
clockwise to increase and counterclockwise to decrease
pressure setting.
3. Always approach the desired pressure from a lower
pressure. When reducing from a higher to a lower setting,
first reduce to some pressure less than that desired, then
bring up to the desired pressure.
NOTE
With non-relieving filter/regulators, make pressure
reductions with some air flow in the system. If made
under no flow (dead-end) conditions, the
filter/regulator will trap the over-pressure in the
downstream line.
4. Push adjusting knob down to lock pressure setting; pull up
to release. Install tamper resistant knob (see Replacement
Items) to make setting tamper resistant.
SERVICING
1. Depress manual drain to expel accumulated liquids. Keep
liquids below element (31).
2.Clean or replace filter element when dirty.
DISASSEMBLY
1. Filter/regulator can be disassembled without removal from
air line.
2. Shut off inlet pressure. Reduce pressure in inlet and outlet
lines to zero.
3. Turn adjustment (2 or 5A) fully counterclockwise.
4. Turn bowl and bonnet counterclockwise and remove from
body.
5. Disassemble in general accordance with the item numbers
on exploded view. Do not remove the manual drain unless
replacement is necessary. Remove and replace drain only if
it malfunctions.
CLEANING
1. Clean plastic bowl with warm water only. Clean other parts
with warm water and soap.
2. Rinse and dry parts. Blow out internal passages in body
(15, 16) with clean, dry compressed air. Blow air through
filter element (31, 34) from inside to outside to remove
surface contaminants.
3. Inspect parts. Replace those found to be damaged. Replace
plastic bowl with a metal bowl if plastic bowl shows signs
of cracking or cloudiness.
ASSEMBLY
1. Lubricate seals and o-rings with o-ring grease. Apply a
small amount of anti-seize lubricant to full length of threads
on metal bowls.
2. Assemble the unit as shown on the exploded view.

PANEL MOUNTING DIMENSIONS
Panel mounting hole diameter: 30 mm (1.19")
Panel thickness: 2 to 6 mm (0.06" to 0.25")
INSTALLATION
1. Shut off air pressure. Install filter/regulator in air line -
● vertically (bowl down),
● with air flow in direction of arrow on body,
● upstream of 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. On filters equipped with an automatic drain, slip 1/4" I.D.
flexible tube over protrusion on bottom of bowl. Avoid
restrictions in the tube. Bowl protrusion is also threaded
to accept 1/8" pipe thread fitting.
4. Turn bowl fully clockwise into body before pressurizing.
5.
Install a pressure gauge or plug the gauge ports. Gauge
ports can also be used as additional outlets for regulated air.
Early Bonnet and Body - Valve seat (9), seal (10), and
gasket (37) used with early body. Early body used a stud
(32) to secure polypropylene element to the body.
Current element (31) replaces the element and stud.
Current Bonnet and Body - Valve seat (11) and seal (12)
used only with current body. Gasket (37) also used with
current body when sintered bronze element (32, 33, 34, 35)
is installed.
NOTES FOR CURRENT AND EARLY BOWLS
Current bowls use a lip on the bowl inside
diameter to retain bowl o-ring. Early bowls use
a lip on the bowl outside diameter to retain
bowl o-ring. Service kits contain current and
early bowl o-rings. The larger of the o-rings is
used on the early bowls.

Instructions
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.
Polycarbonate plastic bowls can be damaged and
possibly burst if exposed to such substances as certain
solvents, strong alkalies, compressor oils containing esterbased 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.
If outlet pressure in excess of the filter/regulator
pressure setting could cause downstream equipment to
rupture or malfunction, install a pressure relief device
downstream of the filter/regulator. The relief pressure and
flow capacity of the relief device must satisfy system
requirements.
The accuracy of the indication of pressure gauges can
change, both during shipment (despite care in packaging)
and during the service life. If a pressure gauge is to be
used with these products and if inaccurate indications may
be hazardous to personnel or property, the gauge should be
calibrated before initial installation and at regular intervals
during use.
Before using these products with fluids other than air,
for non industrial applications, or for life-support systems
consult Norgren.
