User manual BENDIX DRYER RESERVOIR MODULE WITH A BENDIX AD-IS AIR DRYER BROCHURE

[. . . ] The Bendix® Dryer Reservoir Module with a Bendix® AD-IS® Air Dryer A New Standard in Design & Quality. Featuring: A long life Bendix® AD-IS® air dryer, incorporating the performance and quality of our popular AD-9® air dryer. [. . . ] This means that when the air pressure in the system builds from zero, the order in which the reservoirs fill is much different than a traditional three(3) reservoir system. Observe the pressure gauges of the vehicle as system pressure builds from 0 psi. The primary reservoir gauge rises until it reaches about 110 psi, then the secondary reservoir begins to build. As the secondary reservoir builds initial pressure to approximately 55 psi ­ then to approximately 85 psi ­ a sequence of two pressure protection valves open, supplying vehicle accessories. At about 110 psi, both primary and secondary reservoirs charge, simultaneously, until governor cut-out is reached. MAINTENANCE INTERVALS In general, we recommend that maintenance checks be made every 900 operating hours; 25, 000 miles; or three(3) months, whichever comes first (see warranty publication BW1715 for details). Important: Review the warranty policy before performing any intrusive maintenance procedures. Because no two vehicles operate under identical conditions, maintenance and maintenance intervals will vary. Experience is a valuable guide in determining the best maintenance interval for any one particular operation. [. . . ] The AD-IS® air dryer pressure protection valves, however, will close at pressures at or above 70 psi, protecting the remaining brake circuit from further loss of pressure.
