Symbols
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 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.

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 nonrelieving 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.
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 bonnet assembly
onto body and tighten per Figure 1.
10. Install bowl into body and tighten, hand tight, plus 1/4 turn.
Service Kits Available
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.
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.
