Rosemount 304 Traditional Manifold installation procedure
To install a traditional manifold to a Rosemount 3051SMV:
1. Align the traditional 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
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
Section 4: Operation and Maintenance
Coplanar transmitters
3-valve and 5-valve manifolds
Performing zero trim at static line pressure
Improper installation or operation of manifolds may result in process leaks, which may cause death or
serious injury.
In normal operation the two isolate (block) valves between
the process ports and transmitter will be open and the
equalize valve will be closed.
1. To zero trim the transmitter, close the isolate valve on the
low side (downstream) side of the transmitter.
