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 2-15 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.
