The hazard
NOTE: VEHICLES EQUIPPED WITH ROCKWELL WABCO SYSTEM SAVER 1000 AIR DRYERS. IN AIR BRAKE SYSTEMS REQUIRING A LARGE VOLUME OF AIR TO PASS THROUGH THE DRYER IN A SHORT PERIOD OF TIME, THE DRYER CANNOT REMOVE ALL OF THE MOISTURE FROM THE AIR. IN A COLD ENVIRONMENT THIS MOISTURE MAY FREEZE AND EFFECTIVELY BLOCK THE AIR LINES DOWNSTREAM OF THE DRYER RESULTING IN AN AIR PRESSURE BUILD UP IN THE DRYER. THIS AIR PRESSURE MAY EVENTUALLY CAUSE THE DRYER CARTRIDGE TO SEPARATE FROM THE DRYER. THE SEPARATED CARTRIDGE MAY CAUSE BODILY INJURY TO ANYONE STANDING NEAR THE DRYER AT THE INSTANT OF SEPARATION. CORRECTION: PRESSURE RELIEF VALVES WILL BE INSTALLED IN THE DRYER OUTLET PORTS ON THE AFFECTED VEHICLES.
