Note

If using thread tape, be sure the thread tape does not strip when the manifold assembly is started.

5.Wrench tighten manifold into process connection. (Note: Minimum toque value is 425 in-lbs)

6.Count how many threads are still showing. (Note: Minimum engagement is 3 revolutions)

7.Subtract the number of threads showing (after tightening) from the total threads to calculate the revolutions engaged. Further tighten until a minimum of 3 rotations is achieved.

8.For block and bleed manifold, verify the bleed screw is installed and tightened. For two-valve manifold, verify the vent plug is installed and tightened.

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

3.5.3Rosemount 304 Conventional Manifold installation procedure

To install a 304 Conventional Manifold to a 2051 Wireless 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 37 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 applicable, install flange adapters on the process end of the manifold using the 1.75-in. flange bolts supplied with the transmitter.

3.5.4Manifold operation

Improper installation or operation of manifolds may result in process leaks, which may cause death or serious injury.

Always perform a zero trim on the transmitter/manifold assembly after installation to eliminate any shift due to mounting effects. See Section 5: Operation and maintenance, “Sensor Trim Overview” on page 67.
