Rosemount 304

Conventional Manifold

Installation Procedure

To install a 304 Conventional Manifold to a 3051S 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 module housing plane of

flange web (i.e. bolt hole) but must not contact module 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.
