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.
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 without notice.
EXTRA COPIES OF THESE INSTRUCTIONS ARE AVAILABLE FOR
INCLUSION IN EQUIPMENT / MAINTENANCE MANUALS THAT UTILIZE
THESE PRODUCTS. CONTACT YOUR LOCAL REPRESENTATIVE.
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 in the direction of arrow
on body.
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:
4A. On SB1, disengage the adjusting knob by pulling upward. Turn
adjusting knob counterclockwise until the compression is released
from the pressure control spring.
4B. On SB2, push down on the adjusting knob while turning knob
counterclockwise until the compression is released from the
pressure control spring. (Knob is locked when up.)
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 settings have been reached,
push the knob down to lock this pressure setting on the SB1 or up
to lock on the SB2.

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.

Servicing Filter Element - (Refer to Figure 1)
1. Unscrew and remove bowl.
2. Unscrew the filter holder 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 filter stem and the filter body.
5. Attach filter holder 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)
1A. On SB1, disengage the adjusting knob by pulling upward. Turn
adjusting knob counterclockwise until the compression is released
from the pressure control spring.
1B. On SB2, push down on the adjusting knob while turning knob
counterclockwise until the compression is released from the
pressure control spring. (Knob is locked when up.)
2. Remove the bonnet and bowl assemblies by unscrewing the bonnet
and bowl from the body.
3. Remove diaphragm assembly from bonnet assembly.

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.

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.

4. Remove filter stem, filter element, poppet assembly, poppet
return spring.
5. Clean and carefully inspect parts for wear or damage.
If replacement is necessary, use parts from service kits. Clean
bowl.
6. Lubricate o-rings with grease found in service kits.
7. Install poppet return spring, poppet assembly, and filter holder.
IMPORTANT: The Filter / Regulator will not operate properly if
the defector is not installed properly. The deflector must be
installed between the filter stem and filter body.
8. Install filter element and firmly tighten baffle onto the filter stem.
9. Install diaphragm assembly into body assembly. Assemble
