OPERATION & LEAKAGE TESTS
Build the air system to governor cutout.  Shut off the engine.
Using a soap solution, check all lines and fittings leading
to and from the PuraGuard QC
 filter for leakage and
integrity.  Repair any excessive leaks — exceeding a 1
inch bubble in 5 seconds — before restoring vehicle to
service.
WARNING! PLEASE READ AND FOLLOW
THESE INSTRUCTIONS TO 
AVOID
PERSONAL INJURY OR DEATH:
When working on or around a vehicle, the following
general precautions should be observed at all times.
1.
Park the vehicle on a level surface, apply the
parking brakes, and always block the wheels.
Always wear safety glasses.
2.
Stop the engine and remove ignition key when
working under or around the vehicle.  When
working in the engine compartment, the engine
should be shut off and the ignition key should be
removed. Where circumstances require that the
engine be in operation, EXTREME CAUTION should
be used to prevent personal injury resulting from
contact with moving, rotating, leaking, heated or
electrically charged components.
3.
Do not attempt to install, remove, disassemble or
assemble a component until you have read and
thoroughly understand the recommended
procedures.  Use only the proper tools and observe
all precautions pertaining to use of those tools.
4.
If the work is being performed on the vehicle’s air
brake system, or any auxiliary pressurized air
systems, make certain to drain the air pressure from
all reservoirs before beginning ANY work on the
vehicle.  If the vehicle is equipped with an AD-IS
air dryer system or a dryer reservoir module, be
sure to drain the purge reservoir.
5.
Following the vehicle manufacturer’s
recommended procedures, deactivate the electrical
system in a manner that safely removes all
electrical power from the vehicle.
6.
Never exceed manufacturer’s recommended
pressures.
7.
Never connect or disconnect a hose or line
containing pressure; it may whip. Never remove a
component or plug unless you are certain all
system pressure has been depleted.
8.
Use only genuine Bendix
®
 replacement parts,
components and kits. Replacement hardware,
tubing, hose, fittings, etc. must be of equivalent
size, type and strength as original equipment and
be designed specifically for such applications and
systems.
9.
Components with stripped threads or damaged
parts should be replaced rather than repaired.  Do
not attempt repairs requiring machining or welding
unless specifically stated and approved by the
vehicle and component manufacturer.
10. Prior to returning the vehicle to service, make
certain all components and systems are restored
to their proper operating condition.
PURAGUARD QC
 
OIL COALESCING FILTER
REMOVAL
This PuraGuard QC
 filter removal process is presented in
the event it becomes necessary to replace the entire
coalescing filter.
Normal service and parts replacement does not require
removal of the PuraGuard QC
 
filter from the vehicle.
1. Park the vehicle on a level surface and prevent movement
by means other than the brakes.
2. Drain all reservoirs to 0 p.s.i.
3. Identify and disconnect the two air hoses from the
PuraGuard QC
 filter.
4. Remove the two bolts that secure the bracket to the
vehicle, and remove the PuraGuard QC
 filter from the
vehicle.
REPLACING OR RETROFITTING THE
PURAGUARD QC
 OIL COALESCING FILTER
General
The following retrofit instructions are presented for reference
purposes only since Bendix aftermarket retrofit and
replacement PuraGuard QC
 filter systems are packaged
with the most up-to-date installation instructions. The
instructions packaged with the filter should be followed in
lieu of those presented here.
ASSEMBLY
1. The top of the system filter has an arrow symbol showing
the air flow direction (see figure 1).  Secure the mounting
bracket to the body and spin-on cartridge.
RETROFIT:  LOCATING THE PURAGUARD
QC
 FILTER ON THE VEHICLE
1. The PuraGuard QC
 filter must be mounted vertically
(±5°) and must not be exposed to direct wheel splash
(located behind axle mud flap is acceptable).
2. Locate it as close to the first (supply) reservoir as
possible and upstream of the supply reservoir (see figure
3).
3. To minimize vibration, mount the PuraGuard QC
™ 
filter
on a frame rail.  If the vehicle requires the filter to be
directly mounted to the reservoir, be sure to only use a
high strength nipple fitting.  (See further notes under
Connecting the Air Hoses.)
