3.5.1 Rosemount 305 Integral Manifold installation procedure
To install a Rosemount 305 Integral Manifold to a Rosemount 3051SMV:
1. Inspect the PTFE SuperModule O-rings. If the O-rings are undamaged, reusing them is recommended.
If the O-rings are damaged (e.g. nicks), replace them with new O-rings.
Note
If replacing the O-rings, be careful not to scratch or deface the O-ring grooves or the surface of the
isolating diaphragm when removing the damaged O-rings.
2. Install the Integral manifold on the SuperModule process connection. Use the four manifold bolts for
alignment. Finger tighten the bolts, then tighten the bolts incrementally in a cross pattern to final
torque value. See “Flange bolts” on page 71 for complete bolt installation information and torque
values. When fully tightened, the bolts should extend through the top of the SuperModule housing.
3. If the PTFE SuperModule O-rings have been replaced, the flange bolts should be re-tightened after
installation to compensate for seating of the O-rings.
4. If applicable, install flange adapters on the process end of the manifold using the 1.75-in. flange bolts
supplied with the transmitter.
3.5.2 Rosemount 304 Conventional Manifold installation procedure
To install a Rosemount 304 Conventional Manifold to a Rosemount 3051SMV:
1. Align the conventional manifold with the transmitter flange. Use the four manifold bolts for
alignment.
2. Finger tighten the bolts, then tighten the bolts incrementally in a cross pattern to final torque value.
See “Flange bolts” on page 71 for complete bolt installation information and torque values. When
fully tightened, the bolts should extend through the top of the SuperModule assembly bolt hole but
must not contact the SuperModule housing.
3. If applicable, install flange adapters on the process end of the manifold using the 1.75-in. flange bolts
supplied with the transmitter.
3.5.3 Manifold operation
Always perform a zero trim on the transmitter/manifold assembly after installation to eliminate any shift
due to mounting effects. See “Sensor trim overview” on page 90.
Improper installation or operation of manifolds may result in process leaks, which may cause death or
serious injury.
