DESCRIPTION

The function of the Bendix

AD-IS

EverFlow

assembly is

to provide heavy vehicles that use large amounts of air with

a dryer system that facilitates continuous flow drying. This

assembly provides, in a single package, all the components

necessary to operate two dryers. The assembly determines

if high air demand is needed and continuously switches

between dryers every 30 seconds until the high air demand

ceases. When high air demand is not needed, the assembly

uses the dryers as if in a normal braking system. Each

dryer cycles as the air brake system requires. This feature

prevents wasted air and unnecessary cycles. The assembly

uses an electronic module that determines air demand and

sequences the dryers for maximum efficiency.

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

AD-IS

air dryer system, a Bendix

DRM

™

dryer reservoir module, or a Bendix

AD-9si

™

air

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. Never remove

a component or plug unless you are certain all

system pressure has been depleted.

▲ Use only genuine Bendix

brand replacement

parts, components and kits. Replacement

hardware, tubing, hose, ﬁ ttings, 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 Bendix

Wingman

Advanced

™

-equipped vehicle.

▲ You should consult the vehicle manufacturer's operating and service manuals, and any related literature,

in conjunction with the Guidelines above.

The Bendix

AD-IS

air dryer collects and removes air

system contaminants in solid, liquid and vapor form before

they enter the brake system. It provides clean, dry air to

the components of the brake system which increases the

life of the system and reduces maintenance costs. Daily

manual draining of the reservoirs is eliminated, but still may

be mandated by law.
The function of the pressure protection valves is to protect

each reservoir from a pressure loss in the other reservoir or

a pressure loss in an air accessory. Each of the pressure

protection valves in the AD-IS air dryer may have different

pressure settings, but these are factory set and

must not

be changed or adjusted.
