RETROFITTING THE BENDIX® AD-RP™AIR DRYER

GENERAL

The following retrofit instructions are presented for reference purposes only. Bendix® replacement air dryers are packaged with the most up-to-date installation instructions. The instructions packaged with the Bendix® AD-RP™air dryer should be followed instead of those presented here. The preceding portion of this manual deals with "in-service" repair and/or replacement of the AD-RP air dryer. This portion of the manual is concerned with installing an AD-RP air dryer on a vehicle not previously equipped with one.

VEHICLE APPLICATION REQUIREMENTS

The basic application requirements presented here apply to a standard air dryer installation. The majority of highway vehicles in use today will meet these basic requirements, however some may not. Examples of vehicles that may not meet the requirements include refuse trucks, city coaches, bulk trailer unloading operations and other high air consumption systems. While the AD-RP air dryer can be used on these vehicles, the standard installation procedure presented in this manual may require modifi cation to ensure proper operation and service life. Consult your local authorized Bendix parts outlet or sales representative for additional information.

1.Charge Cycle Time - The AD-RP air dryer is designed to provide clean, dry air for the brake system. When a vehicle's air system is used to operate non-brake air accessories it is necessary to determine that — during normal, daily operation — the compressor should recover from governor "cut-in" to governor "cut-out" (usually 110 psi to 130 psi) in 90 seconds or less at engine RPMs commensurate with the vehicle vocation. Note: The Bendix AD-RP air dryer must be used in conjunction with governors which have a 120 to 130 psi nominal cut-out pressure. If a governor is used that is not within this limitation, contact your Bendix parts outlet or sales representative for additional information. If the recovery time consistently exceeds this limit, it may be necessary to "by-pass" the air accessory responsible for the high air usage.

2.Purge Cycle Time - During normal vehicle operation, the air compressor must remain unloaded for a minimum of 30 seconds. This minimum purge time is required to ensure complete regeneration of the desiccant material. If the purge time is occasionally shorter than the times specifi ed, no permanent ill effect should be expected. If the purge time is consistently less than the minimum, however, an accessory by-pass system must be installed.

3.European Air Brake Systems - The AD-RP air dryer must not be installed in brake systems that incorporate compressors without integral unloading mechanisms and/or utilize a compressor discharge line unloader valve. When vehicles of this type are encountered, other Bendix air dryer models must be used. Consult your local authorized Bendix parts outlet or sales representative for additional information.

4.Air Compressor Size - The AD-RP air dryer was designed primarily for use with compressors rated up to 30 CFM. Contact and authorized Bendix parts outlet or a Bendix sales representative for assistance when using the AD-RP dryer with a compressor which has a rated displacement exceeding 30 CFM.

5.Holset "E or QE" Type Air Compressors - The AD-RP dryer can be installed with the Holset Type "E or QE" compressor. When the AD-RP air dryer is used in this installation, the Holset ECON valve should be removed and the special orifi ce check valve in the "make-up" line should be removed and replaced with a conventional single check valve.
