WARNING
To avoid unpredictable system behavior that can cause personal
injury and property damage:
• Disconnect electrical supply (when necessary) before installation,
servicing, or conversion.
• Disconnect air supply and depressurize all air lines connected
to this product before installation, servicing, or conversion.
• Operate within the manufacturer’s specified pressure,
temperature, and other conditions listed in these instructions.
• Medium must be moisture-free if ambient temperature is below
freezing.
• Service according to procedures listed in these instructions.
• Installation, service, and conversion of these products must be
performed by knowledgeable personnel who understand how
pneumatic products are to be applied.
• After installation, servicing, or conversion, air and electrical
supplies (when necessary) should be connected and the product
tested for proper function and leakage. If audible leakage is
present, or the product does not operate properly, do not put
into use.
• Warnings and specifications on the product should not be
covered by paint, etc. If masking is not possible, contact your
local representative for replacement labels.

Filter / Regulator
Installation
1. The Filter / Regulator should be installed with reasonable
accessibility for service whenever possible – repair service kits
are available. Keep pipe or tubing lengths to a minimum with
inside clean and free of dirt and chips. Pipe joint compound
should be used sparingly and applied only to the male pipe –
never into the female port. Do not use PTFE tape to seal pipe
joints – pieces have a tendency to break off and lodge inside
the unit, possibly causing malfunction. Also, new pipe or hose
should be installed between the Filter / Regulator and equipment
being protected.
2. The upstream pipe work must be clear of accumulated dirt and
liquids.
3. Select a Filter / Regulator location as close as possible to the
equipment being protected.
4. Install Filter / Regulator so that air flows into port labelled “IN”
on body.
WARNING
FAILURE OR IMPROPER SELECTION OR IMPROPER USE OF
THE PRODUCTS AND/OR SYSTEMS DESCRIBED HEREIN OR
RELATED ITEMS CAN CAUSE DEATH, PERSONAL INJURY
AND PROPERTY DAMAGE.
This document and other information from The Company, its
subsidiaries and authorized distributors provide product and/or
system options for further investigation by users having technical
expertise. It is important that you analyze all aspects of your
application, including consequences of any failure and review the
information concerning the product or systems in the current
product catalog. Due to the variety of operating conditions and
applications for these products or systems, the user, through its
own analysis and testing, is solely responsible for making the final
selection of the products and systems and assuring that all
performance, safety and warning requirements of the application
are met.
The products described herein, including without limitation, product
features, specifications, designs, availability and pricing, are subject
to change by The Company and its subsidiaries at any time

REPRESENTATIVE.
CAUTION
Polycarbonate bowls, being transparent and tough, are ideal for use
with Filters and Lubricators.They are suitable for use in normal industrial
environments, but should not be located in areas where they could be
subjected to direct sunlight, an impact blow, nor temperatures outside
of the rated range. As with most plastics, some chemicals can cause
damage. Polycarbonate bowls should not be exposed to chlorinated
hydrocarbons, ketones, esters and certain alcohols. They should not
be used in air systems where compressors are lubricated with fire-
resistant fluids such as phosphate ester and diester types.
Metal bowls are recommended where ambient and/or media conditions
are not compatible with polycarbonate bowls. Metal bowls resist the
action of most such solvents, but should not be used where strong
acids or bases are present or in salt laden atmospheres. Consult the
factory for specific recommendations where these conditions exist.
TO CLEAN POLYCARBONATE BOWLS USE MILD SOAP AND
WATER ONLY! DO NOT use cleansing agents such as acetone,
benzene, carbon tetrachloride, gasoline, toluene, etc., which are
damaging to this plastic.
!
WARNING
Product rupture can cause serious injury.
Do not connect regulator to bottled gas.
Do not exceed maximum primary pressure rating.

Introduction
Follow these instructions when installing, operating, or servicing the
product.
Application Limits
These products are intended for use in general purpose compressed
air systems only.

Service
Caution: Disconnect or shut off air supply and exhaust the
primary and secondary pressures before servicing unit.
Turning the adjusting knob counterclockwise does not vent
downstream pressure on non-relieving regulators. Downstream
pressure must be vented before servicing regulator.
Caution: Grease packets are supplied with kits for lubrication
of seals. Use only mineral based grease or oils. Do not use
synthetic oils such as esters. Do not use silicones.
Note: After servicing unit, turn on air supply and adjust regulator
to the desired downstream pressure. Check unit for leaks. If
leakage occurs, do not operate - conduct repairs and retest.
Servicing Filter Element - (Refer to Figure 1)
1. Unscrew and remove Bowl.
2.
Unscrew the Element Retainer from Body and then remove Element.
3. Clean all internal parts and bowl before reassembling.
4. Install new element. IMPORTANT: The Filter / Regulator will not
operate properly if the Deflector is not installed properly. The
Deflector must be installed between the Element Retainer and
the Filter Body.
5. Attach Element Retainer and finger tighten firmly.
6. Replace Bowl Seal. Lightly lubricate new seal to assist with
retaining it in position.
7. Install Bowl into Body and tighten; hand tight, plus 1/4 turn.
Servicing Regulator - (Refer to Figure 1)
1. Disengage the Adjusting Knob by pulling upward. Turn Adjusting
Knob counterclockwise until the compression is released from
the Pressure Control Spring.
2. Remove the Bonnet and Bowl assemblies by unscrewing the
Bonnet and Bowl from the body.
3. Remove Diaphragm Assembly from Bonnet Assembly.
4. Remove Element Retainer, Filter Element, Poppet Assembly,
Poppet Return Spring.
5. Clean and carefully inspect parts for wear or damage. Wipe
parts, clean with soapy water or denatured alcohol but do not
use denatured alcohol on plastic bowl or sight gauge. If
using compressed air to blow dry, be sure to wear appropriate
eye protection. If replacement is necessary, use parts from service
kits. Clean Bowl.

6. Lubricate O-rings with grease found in service kits.
7.
Install Filter Element onto the Element Retainer and firmly tighten.
8. Install Poppet Return Spring, Poppet Assembly, and Element
Retainer. IMPORTANT: The Filter / Regulator will not operate
properly if the Defector is not installed properly. The Deflector
must be installed between the Element Retainer and Filter Body.
9. Install Diaphragm Assembly into Body Assembly. Assemble
Bonnet Assembly onto Body and tighten per Figure 1.
10. Install Bowl into Body and tighten, hand tight, plus 1/4 turn.
5. Install Filter / Regulator vertically with the bowl drain mechanism
at the bottom. Free moisture will thus drain into the sump (“quiet
zone”) at the bottom of the bowl.
6. Gauge ports are located on both sides of the Filter / Regulator
body for your convenience. It is necessary to install a gauge or
socket pipe plugs into each port during installation.
Operation
1. Both free moisture and solids are removed automatically by the
filter.
2. Manual drain filters must be drained regularly before the separated
moisture and oil reaches the bottom of the Baffle or End Cap.
3. The Filter Element should be removed and replaced when
pressure differential across the filter is 69 kPa (10 PSIG).
4. Before turning on the air supply, disengage the Adjusting Knob
by pulling upward. Turn Adjusting Knob counterclockwise until
the compression is released from the Pressure Control Spring.
5. Then turn Knob clockwise and adjust regulator to desired
downstream pressure. This permits pressure to build up slowly
in the downstream line.
6. To decrease regulated pressure settings, always reset from a
pressure lower than the final setting required. Example, lowering
the secondary pressure from 550 to 410 kPa (80 to 60 PSIG) is
best accomplished by dropping the secondary pressure to 350
kPa (50 PSIG), then adjusting upward to 410 kPa (60 PSIG).
7. When desired secondary pressure setting has been reached,
push the Knob down to lock this pressure setting.

Lightly grease with provided lubricant.
Inspect for nicks, scratches, and surface imperfections.
If present, reduced service life is probable and
future replacement should be planned.
Clean with lint-free cloth.
