PURGE CONTROL LINE

1.Install a purge control air line having a minimum inside diameter of 3/16" between the Bendix® AD-RPair dryer control port and an unused unloader port on the governor. The control line must be plumbed direct to the governor and not in series with automatic drain valves, lubrication systems, etc.

2.The control line should slope downward to the AD-RP dryer without forming potential water traps.

DISCHARGE LINE

GENERAL

Refer to Appendix A / Table A for recommended discharge line lengths and sizes for various vehicle applications and vocations.

PURGE EXHAUST LINE

1.If it is necessary to direct AD-RP air dryer discharge contaminates away from vehicle components, a 1” (25.4 mm) I.D. hose can be clamped on the AD-RP dryer exhaust.

WIRING THE HEATER/THERMOSTAT

1.Determine the vehicle's electrical system voltage and make certain that the Bendix AD-RP air dryer that is to be installed contains the same voltage heater. Confi rm the proper voltage by noting the color of the heater and thermostat connector.

The AD-RP air dryer is available with either a 12- or 24-volt heater. Each uses 90 watts of power.

2.A separate wire harness and splice kit is with all AD-RP air dryer replacements and retro-fi t kits. Refer to the instructions contained in that kit for the proper wiring procedure.

TESTING THE BENDIX AD-RP AIR DRYER

GENERAL OPERATIONAL STATEMENT

The AD-RP remote purge air dryer, operates differently than integral purge air dryers such as the Bendix® AD-9®air dryer.

The "Remote Purge", designation is used because this air dryer uses a small additional volume mounted on the frame rail to purge or dry the desiccant material. During the purge cycle, the pressure in this purge volume will drop to 0 psi. This volume is separate from the air brake system volume, no pressure drop in the air brake system should be caused by the purge cycle of the AD-RP air dryer.
