Introduction

Scope of Manual
This instruction manual provides installation, maintenance, and parts ordering information for the NPS 2 through 12 Fisher WhisperTube modal attenuator.
Description
The WhisperTube is a passive reactive silencer designed for installation downstream of the control valve or other equipment contributing to system noise. Requiring negligible pressure drop across the device, the WhisperTube achieves system noise reduction across a wide range of fluid flow rates, pressures and temperatures.
Do not install, operate, or maintain a 6060 WhisperTube without being fully trained and qualified in valve, actuator, and accessory installation, operation, and maintenance. To avoid personal injury or property damage, it is important to carefully read, understand, and follow all the contents of this manual, including all safety cautions and warnings. If you have any questions about these instructions, contact your Emerson sales office before proceeding.

Installation

WARNING
Always wear protective gloves, clothing, and eyewear when performing any installation operations to avoid personal injury.
To avoid personal injury or property damage resulting from the sudden release of pressure, do not install the WhisperTube assembly where service conditions could exceed the limits given on the 6060 nameplate. Use pressure‐relieving devices as required by accepted industry, local, state, or federal codes, and good engineering practices.
Check with your process or safety engineer for any additional measures that must be taken to protect against process media.
If installing into an existing application, also refer to the WARNING at the beginning of the Maintenance section in this instruction manual.
Use proper lifting and rigging practices while moving the WhisperTube. Failure to utilize safe lifting practices may result in equipment damage and/or personal injury.
Avoid personal injury or property damage caused by uncontrolled movement or dropping of the WhisperTube assembly.
The threaded lifting provisions are for installation of hoist rings or lifting eye bolts and are sized for lifting the 6060 only. Do not use lifting provisions to lift the WhisperTube if piping or other equipment is attached.

1. If the WhisperTube will be placed in storage prior to installation, protect the flanges and keep the inside of the body dry and clear of foreign material.
2. Install a three‐valve bypass around the 6060 assembly if continuous operation will be necessary during inspection and maintenance.
3. Inspect the WhisperTube body for damage and be certain the body internal cavities are free of foreign material.
4. Be certain that adjacent pipelines are free of any foreign material, such as pipe scale or welding slag, that could damage the WhisperTube.
5. The standard flow direction is with the wave spring (key 4) facing upstream.
6. The WhisperTube may be installed in any orientation and achieve system noise reduction. The recommended orientation for a horizontal pipeline is with the pipe plug and drain port facing down to allow removal of any potential process liquid buildup.
7. Install suitable line flange gaskets and insert the 6060 assembly between the pipeline flanges.
8. Center the WhisperTube by making sure the mating flanges are aligned. Insert flange studs and tighten nuts in a star pattern to ensure the flange gaskets are compressed evenly.

Maintenance

WARNING
Avoid personal injury or damage to property from sudden release of pressure or uncontrolled process fluid. Before starting disassembly:

• Always wear protective gloves, clothing, and eyewear when performing any maintenance operations to avoid personal injury.
• Use bypass valves or completely shut off the process to isolate the WhisperTube from process pressure.
• Remove process pressure and drain the WhisperTube if necessary.
• Use lock‐out procedures to be sure that the above measures stay in effect while you work on the equipment.
• Check with your process or safety engineer for any additional measures that must be taken to protect against process media.

Disassembly

1. Isolate the WhisperTube from the process pressure, relieve all process pressure, and drain any internal liquid buildup if necessary.

2.  Remove the WhisperTube from the pipeline.
   Follow steps 3-5 for a single piece body construction (NPS 2-6)

3. Remove the screen retainer (key 8) by loosening the two retainer screws (key 11).

4. Remove the wave spring (key 4) and perforated screen tube (key 2).

5. Inspect the perforated screen tube, wave spring, and internal surfaces of the WhisperTube body (key 1) and replace damaged components as necessary. Visually inspect the flange serrated surfaces for any damage that may prevent proper sealing.
   Follow steps 6-9 for the two-piece body construction (NPS 8-12)

6. Set the WhisperTube in a vertical position with one flange resting on a clean soft surface. Use caution to protect the flange serrated surfaces. Separate the two body halves by removing the body flange studs and nuts (keys 13 and 14).

7. Remove the spiral wound gasket (key 12) and perforated screen tube (key 3).

8. The wave spring (key 4) may be accessed and removed from the inlet flange end of the WhisperTube body.

9. Inspect the perforated screen tube, wave spring, and internal surfaces of the WhisperTube body (key 1) and replace damaged components as necessary. Visually inspect the flange serrated surfaces for any damage that may prevent proper sealing.
   Assembly
   Follow steps 10-13 for a single piece body construction (NPS 2-6)

10. Ensure the old flat sheet gasket (Key 9) is removed.

11.  Re-insert the perforated screen tube into the body bore until the end of the tube seats against an internal ledge in the body at the outlet flange end.

12.  Re-install the wave spring.

13. Center a new flat sheet gasket (key 9) on the screen retainer sealing surface and install on the body. Secure the retainer with washers (key 10) and retainer screws (key 11).Follow steps 14-20 for the two-piece body construction (NPS 8-12)

14.  Install the wave spring (key 4) in the groove at the flange end of the inlet body half.

15. Assembly is easiest if the parts are oriented vertically. Place the inlet body half flange end down on a clean soft surface. Use caution to protect the flange end serrated surfaces.

16. Install the perforated screen tube in the inlet body half until it contacts the wave spring.

17. Center the spiral wound gasket (key 12) on the inlet body flange serrated surface.

18.  Lower the outlet body half over the screen. Ensure the drain pipe plugs and the threaded lifting lugs are aligned and located on the same side of the body in both the inlet and outlet halves.

19. Apply anti-seize lubricant compound to the face and threads of the hex nuts and to the threads of the studs. Install the nuts and studs. Use an appropriate torque device to apply the final torque specification (see table 4). Tighten nuts in a star pattern to ensure the spiral wound gasket is compressed evenly.
