OPERATION (See Figure 1)

GENERAL SAFETY GUIDELINES WARNING! PLEASE READ AND FOLLOW

THESE INSTRUCTIONS TO A VOID PERSONAL

Compressed air enters the supply port of the Cyclone DuraDrain™ trailer water separator. The air pressure pushes down on the check valve contained in the purge nut and closes the purge nut drain port. When air enters the supply port of the Cyclone DuraDrain™ trailer water separator a cyclonic action is created.

The cyclonic motion separates the oil, water and particulates. The oil, water and particulates gravitate to the

™

bottom of the Cyclone DuraDrain

trailer water separator where they collect. When the air pressure above the purge nut check valve returns to atmospheric pressure, the check valve moves up and off its seat. The contaminants then drain through the purge nut drain port.

INJURY OR DEATH:

When working on or around a vehicle, the following general precautions should be observed at all times.

1. Park the vehicle on a level surface, apply the

working under or around the vehicle. When working in the e ngine compar tment, t he engine should be shut off and the ignition key should be removed. Where ci rcumstances req uire that the

engine be in operation, EXTREME CAUTION should be used to prevent personal injury resulting from contact wi t h moving , rot ating, leaking , he at e d or electrically charged components.

3. 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.

4. If the wor k is being perfor med on the vehicle’s air brake system, or any auxiliary pressurized air systems, make cer tain to dra in the air pressure from all reservoirs before beginning ANY work on the vehicle. If t he vehicle is equipped with an

AD-IS

air dryer system or a dryer reservoir

module, be sure to drain the purge reservoir.

5. Following the vehicle manufacturer’s recommended procedures, deactivate the electrical system in a manner that safely removes all electrical power fro m t h e vehic l e.

6. Never exceed manufacturer’s recommended pressures.

7. Never connect or disconnect a hose or line containin g pressure; it may w hip. Never remove a componen t or plug unless you are cer tain all system pressure has been depleted.

8. Use only genuine Bendix® 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.

9. Components with stripped threads or damaged parts should be replaced rather than repaired. Do not attempt repairs requiring machining or welding unless speci ﬁ cally st ated and a pproved by the vehicle and component manufacturer.

10. Prior to returning the vehicle to ser vice, make certain all components and systems are restored to their proper operating condition.

11. 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 dr ive axle are lif ted off the groun d and moving.

REMOVAL

Disconnect both upstream glad-hands from the trailer or dolly before beginning work on the Cyclone DuraDrain trailer water separator.

1. Disconnect the supply and delivery line ﬁ ttings.

2. Remove the mounting hardware, and spacer if applicable, that secures the Cyclone DuraDrain™ trailer water separator to the trailer frame rail.

INSTALLATION

A Cyclone DuraDrain™ trailer water separator can be installed in the control and/or the supply line of the trailer between the glad-hand and the ﬁ rst valve in the trailer system. See Figure 3 Trailer Schematic.

1. Identify the control and/or the supply line that the Cyclone DuraDrain™ trailer water separator is to be installed in. The trailer water separator should be installed at the lowest point on the air line, but should not be too low causing a dip in the air line. The Cyclone DuraDrain™ trailer water separator must be installed vertically with the purge nut pointing down to the ground to allow for adequate draining.

2. Locate a mounting position on the trailer frame rail or cross-member. Using the Cyclone DuraDrain™ trailer water separator as a template, mark the location of the mounting holes. Drill two mounting holes. Consult with the trailer manufacturer prior to drilling any holes in the frame rail or cross-member. If a mounting spacer is used, install as shown in Figure 2. Secure using grade 2 or 5 mounting hardware.

3. Cut the air line and install a 3/8” NPT male ﬁ tting at each end. Connect the air lines to the supply and delivery ports of the Cyclone DuraDrain™ trailer water separator.
