hose, fittings, etc. must be of equivalent size, type
and strength as original equipment and be de-
signed specifically for such applications and sys-
tems.

PREVENTIVE MAINTENANCE
Because no two vehicles operate under identical conditions,
maintenance intervals will vary. Experience is a valuable
guide in determining the best maintenance interval for a
vehicle. As a recommended minimum, every 12 months,
100,000 miles or 3,600 operating hours, perform the
Operational and Leakage Tests noted below. Inspect the
filter for unrestricted airflow and blockage from debris
collection. Remove the filter assembly and clean as
needed. If the unit cannot be cleaned of debris, replace the
filter. There are no serviceable parts within the assembly.

in-line filter removed, apply shop air to the
delivery port of the filter to clean the debris from the filter
screen.
NOTE: Disassembly/reassembly of the AF-3
screen.

filter is not recommended. If an assembly does not
meet the Operational and Leakage Tests, it should
be replaced with a new AF-3

3. Clean the contaminants from the control line by applying
shop air to the control line at the gladhand. If the trailer
is connected to the tractor, build system pressure and
make a light brake application. Caution: Pressurized
debris can cause bodily injury, be sure the area
around the trailer is vacated before performing this
operation.

4. Apply thread sealant (do not use Teflon tape) to the
male threads of the control line and the AF-3

filter.
5. Install the filter in the control port of the ABS modulator
or spring brake relay valve. Torque the filter body in place
to approximately 10 pound-feet.

OPERATIONAL AND LEAKAGE TESTS
Apply the brakes and hold 20 psi pressure to the line. Apply
a soap solution to the threads to check for leakage. A one-
inch bubble in 5 seconds is permitted. Repair any excessive
leaks. Perform the Service Check before placing the vehicle
in service.

Apply and release air pressure to the control line containing
the filter. The AF-3
™
in-line filter should allow delivery and
exhausting of the pressure without any noticeable delay in
service brake response. A delay can be identified by making
a service brake application and viewing the actuator push
rods. A delay may indicate foreign material is present in the
control line, preventing the proper flow of air. If a delay is
found, clean or replace the AF-3
service brake response. A delay can be identified by making
a service brake application and viewing the actuator push
rods. A delay may indicate foreign material is present in the
