Manifold Installation

Procedure

Rosemount 304

Conventional Manifold

Installation Procedure

To install a 305 Integral Manifold to a 2051 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 2-13 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.

The 306 Manifold is for use only with a 2051T In-line transmitter.

Assemble the 306 Manifold to the 2051T In-line transmitter with a thread sealant.

To install a 304 Conventional Manifold to a 2051 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 2-6 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.

See “Safety Messages” on page 2-1 for complete warning information.
