2.5 Bolting considerations
If the transmitter installation requires assembly of a process flange,
manifold, or flange adapters, follow these assembly guidelines to ensure a
tight seal for optimal performance characteristics of the transmitter. Only
use bolts supplied with the transmitter or sold by Emerson™ as spare parts.
Figure 2-4 illustrates common transmitter assemblies with the bolt length
required for proper transmitter assembly.

Note
For all other manifolds, contact Customer Central technical support.
Bolts are typically carbon steel or stainless steel. Confirm the material by
viewing the markings on the head of the bolt and referencing Table 2-1 . If
bolt material is not shown in Table 2-1, contact the local Emerson
representative for more information.
Use the following bolt installation procedure:
Procedure
1. Carbon steel bolts do not require lubrication and the stainless steel
bolts are coated with a lubricant to ease installation. However, no
additional lubricant should be applied when installing either type of
bolt.
2. Finger-tighten the bolts.
3. Torque the bolts to the initial torque value using a crossing pattern.
See Table 2-1 for initial torque value.
4. Torque the bolts to the final torque value using the same crossing
pattern. See Table 2-1 for final torque value.

before applying pressure (see Figure 2-5).

2.6 O-rings with flange adapters
WARNING
Failure to install proper flange adapter O-rings may cause process leaks,
which can result in death or serious injury. Only use the O-ring that is
designed for its specific flange adapter.
A. Flange adapter
B. O-ring
C. PTFE-based profile (square)
D. Elastomer profile (round)
Whenever the flange or adapters are removed, visually inspect the O-rings.
Replace them if there are any signs of damage, such as nicks or cuts. If the Orings are replaced, re-torque the flange bolts and alignment screws after
installation to compensate for seating of the O-rings.
2.7 Environmental seal for housing
Thread sealing (PTFE) tape or paste on male threads of conduit is required to
provide a water/dust tight conduit seal and meets requirements of NEMA
Type 4X, IP66, and IP68. Consult factory if other Ingress Protection ratings
are required. For M20 threads, install conduit plugs to full thread
engagement or until mechanical resistance is met.

In-line gage transmitter orientation
The low side pressure port (atmospheric reference) on the in-line gage
transmitter is located under the sensor module neck label. (See Figure 2-6)
Keep the vent path free of any obstruction, including but not limited to
paint, dust, and lubrication by mounting the transmitter so that any
contaminants can drain away.

3 Consider housing rotation
To improve field access to wiring or to better view the optional LCD display:
Procedure
1. Loosen the housing rotation set screw.
2. Turn the housing up to 180° left or right of its original (as shipped)
position.
3. Re-tighten the housing rotation set screw.
Figure 3-1: Transmitter Housing Set Screw
A. LCD display
B. Housing rotation set screw (3/32-in.)
CAUTION
Do not rotate the housing more than 180° without first performing a
disassembly procedure. Over-rotation may sever the electrical
connection between the sensor module and the electronics.

Quick Start Guide 11
Rotate the LCD display
Transmitters ordered with the LCD display will be shipped with the display
installed.
In addition to housing rotation, the optional LCD display can be rotated in
90° increments by squeezing the two tabs, pulling out, rotating and
snapping back into place.
If LCD display pins are inadvertently removed from the electronics board,
carefully re-insert the pins before snapping the LCD display back into place.
Use the following procedure and Figure 3-2 to install the LCD display:
Procedure
1. If the transmitter is installed in a loop, then secure the loop and
disconnect power.

2. Required: Remove the transmitter cover on the electronics board
side (opposite the field terminals side). Do not remove instrument
covers in explosive environments when circuit is live.
3. Engage the four-pin connector into the electronics board and snap
LCD display into place.
4. Required: In order to meet explosion-proof requirements, reinstall
the housing cover and tighten so the cover is fully seated with metal
to metal contact between the housing and cover. After the cover is
seated properly, replace the flathead screw located on the bottom of
the housing cover.
