! 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

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.

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