Installation

2.11.1 Rosemount 305 integral manifold installation procedure

To install a 305 Integral Manifold to a 3051 transmitter:

1. Inspect the PTFE sensor module o-rings. Undamaged o-rings may be reused. If the

o-rings are damaged (if they have nicks or cuts, for example), replace with o-rings

designed for Rosemount transmitter.

Important

If replacing the o-rings, take care not to scratch or deface the o-ring grooves or the surface of

the isolating diaphragm while you remove the damaged o-rings.

2. Install the Integral Manifold on the sensor module. Use the four 2.25-in. 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 11 for complete bolt

installation information and torque values. When fully tightened, the bolts should

extend through the top of the sensor module housing.

3. If the PTFE sensor module o-rings have been replaced, the flange bolts should be

re-tightened after installation to compensate for cold flow of the o-rings.

Note

Always perform a zero trim on the transmitter/manifold assembly after installation to eliminate

mounting effects.

2.11.2 Rosemount 306 integral manifold installation procedure

The 306 Manifold is for use only with a 3051T In-line transmitter.

Assemble the 306 Manifold to the 3051T In-line transmitter with a thread sealant.

2.11.3 Rosemount 304 conventional manifold installation

procedure

To install a 304 Conventional Manifold to a 3051 transmitter:

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 11 for complete bolt installation information

and torque values. When fully tightened, the bolts should extend through the top of

the sensor module housing.

3. Leak-check assembly to maximum pressure range of transmitter.

2.11.4 Manifold operation

Improper installation or operation of manifolds may result in process leaks, which may cause

death or serious injury.

See “Safety messages” on page 5 for complete warning information.
