GENERAL SAFETY GUIDELINES

WARNING! PLEASE READ AND

FOLLOW THESE INSTRUCTIONS

TO AVOID PERSONAL INJURY OR DEATH:

When working on or around a vehicle, the following

guidelines should be observed AT ALL TIMES:

▲Park the vehicle on a level surface, apply the parking

brakes and always block the wheels. Always wear personal

protection equipment.

▲Stop the engine and remove the 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.

▲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.

▲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 a Bendix

DRM

™

dryer reservoir module, or a Bendix

dryer, be sure to drain the purge reservoir.

▲ Following the vehicle manufacturer's recommended

procedures, deactivate the electrical system in a manner

that safely removes all electrical power from the vehicle.

▲Never exceed manufacturer's recommended pressures.

▲Never connect or disconnect a hose or line containing

pressure; it may whip and/or cause hazardous airborne

dust and dirt particles. Wear eye protection. Slowly open

connections with care, and verify that no pressure is

present. Never remove a component or plug unless you are

certain all system pressure has been depleted.

▲ Use only genuine Bendix

components and kits. Replacement hardware, tubing, hose,

ﬁ ttings, wiring, etc. must be of equivalent size, type and

strength as original equipment and be designed speciﬁ cally

for such applications and systems.

▲Components with stripped threads or damaged parts should

be replaced rather than repaired. Do not attempt repairs

requiring machining or welding unless speciﬁ cally stated

and approved by the vehicle and component manufacturer.

▲Prior to returning the vehicle to service, make certain all

components and systems are restored to their proper

operating condition.

▲ For vehicles with Automatic Traction Control (ATC), the ATC

function must be disabled (ATC indicator lamp should be

ON) prior to performing any vehicle maintenance where

one or more wheels on a drive axle are lifted off the ground

and moving.

▲The power MUST be temporarily disconnected from the

radar sensor whenever any tests USING A DYNAMOMETER

are conducted on a vehicle equipped with a Bendix

Wingman

system.

▲You should consult the vehicle manufacturer's operating

and service manuals, and any related literature, in

conjunction with the Guidelines above.

AD-IS

air dryer system, a Bendix

AD-9si

brand replacement parts,

The end cover assembly is retained by a lock ring, as well

as cap screws and retainers, and houses the purge valve

and heater assembly if so equipped.

The heater and thermostat assembly prevent freeze-up

in the purge drain valve when the dryer is used in severe

winter conditions. The heater and thermostat assembly is

standard in the Bendix

equipment for the Bendix

watt and 24 volt / 60 or 120 watt DC heater and thermostat

assembly has an operating range between 45°F and 85°F.

NOTE: The heater and thermostat assembly provided with

the AD-2 air dryer has a 3/16" diameter threaded electrical

terminal protected by a boot. The AD-1 air dryer assembly

incorporates a #16 gauge lead wire. Both types are

serviceable. The heater and thermostat assembly should

be connected to the "on" position of the engine control or

ignition switch and protected with the proper size fuse.

For details on installation, please refer to the "Installation"

section.

OPERATION

The operation of the air dryer can best be described by

separating the operation into two cycles; the charge cycle

and the purge cycle.

air

Charge Cycle: (See Figure 3.) A compressor in the

compressing cycle - With the compressor in its "loaded"

or compressing cycle, air from the compressor enters the

air dryer through the discharge line. When the air – along

with the water and contaminants – enters the air dryer, the

velocity or speed of the air reduces substantially and much

of the entrained liquid drops to the bottom (or sump) of

the air dryer. The initial air ﬂ ow is toward the bottom of the

dryer, but air ﬂ ow direction changes 180° at the bottom of

the air dryer, dropping some water and oil.

The air now passes through the oil separator ﬁ lter which

removes oil and foreign material but does not remove water

vapor. At this point, the air remains saturated with water.

The ﬁ ltered air and vapors penetrate the desiccant drying

bed and the adsorption process begins. Water vapor is

removed from the air by the desiccant.

The unsaturated "dry" air passes through the ball check

valve and purge oriﬁ ce into the purge volume. From the

purge volume air ﬂ ows through an outlet check valve, and

into the ﬁ rst reservoir.

NOTE: The AD-1 air dryer does not incorporate an integral

outlet check valve. The single check valve in an AD-1 air

dryer installation would be located in the line between the

AD-1 air dryer outlet port and the ﬁ rst reservoir.
