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.

2. The upstream pipe work must be clear of accumulated dir t 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 ver tically 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 por ts 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 Standard Knob, unlock the adjusting knob by pulling upward.

Turn adjusting knob counterclockwise until the compression is
released from the pressure control spring.

4B. On tamper resistant model, pressure is preset. Do not attempt to

adjust.

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 secondar y pressure settings have been reached,
push the knob down to lock this pressure setting on the BB3.

Operating Temperature Range: 4°C to 51,7°C (40°F to 125°F)

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.

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: Do not use synthetic oils suc h 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.

5. Clean and carefully inspect parts for wear or damage.
If replacement is necessary, use parts from ser vice kits. Clean
bowl.

6. Lubricate o-rings with grease found in service kits.

7. Install poppet retur n 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.

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 BB3, disengage the adjusting knob by pulling upward. Turn

adjusting knob counterclockwise until the compression is released
from the pressure control spring.

1B. On BB3 with tamper resistant control, do not adjust setting.

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.
