NOTICE

This installation guide provides basic guidelines for the Rosemount 4088 MultiVariable
Transmitter (reference manual document number 00809-0100-4088). It does not provide
instructions for diagnostics, maintenance, service, or troubleshooting. Refer to the 4088
MultiVariable Transmitter Reference Manual for more instruction. All documents are available
electronically at www.emersonprocess.com/rosemount.

Procedures and instructions in this section may require special precautions to
ensure the safety of the personnel performing the operation. Information that
raises potential safety issues is indicated with a warning symbol ( ). Refer to the
following safety messages before performing an operation preceded by this
symbol.

Explosions could result in death or serious injury.

Installation of this transmitter in an explosive environment must be in accordance with the
appropriate local, national, and international standards, codes, and practices. Review the
approvals section of the 4088 MultiVariable Transmitter Reference Manual (00809-0100-4088)
for any restrictions associated with a safe installation.

 Before connecting any instruments in an explosive atmosphere, ensure any instruments in the

loop are installed in accordance with intrinsically safe or non-incendive field wiring practices.

 In an Explosion-proof/Flameproof installation, do not remove the transmitter covers when

power is applied to the unit.

Process leaks may cause harm or result in death.

 Install and tighten process connectors before applying pressure.

Electrical shock can result in death or serious injury.

 Avoid contact with the leads and terminals. High voltage that may be present on leads can

cause electrical shock.

Conduit/cable entries

 Unless marked, the conduit/cable entries in the transmitter housing use a 1/2-14 NPT thread

form. Entries marked "M20" are M20 x 1.5 thread form. On devices with multiple conduit
entries, all entries will have the same thread form. Only use plugs, adapters, glands, or conduit
with a compatible thread form when closing these entries.

 When installing in a hazardous location, use only appropriately listed or Ex certified plugs,

adapters, or glands in cable/conduit entries.

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 Process Management as spare parts.

Figure 1 illustrates common transmitter assemblies with the bolt length required

for proper transmitter assembly.

Bolts are typically carbon steel or stainless steel. Confirm the material by viewing
the markings on the head of the bolt and referencing Figure 2. If bolt material is
not shown in Figure 2, contact the local Emerson Process Management
representative for more information.

Use the following bolt installation 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

Figure 2 for initial torque value.

4. Torque the bolts to the final torque value using the same crossing pattern. See

Figure 2 for final torque value.

5. Verify the flange bolts are protruding through the sensor module before
applying pressure (see Figure 3).

O-rings with flange adapters

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 is square
D. Elastomer profile is 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 O-rings

are replaced, re-torque the flange bolts and alignment screws after installation to
compensate for seating of the O-rings.

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 4).

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.

A. Low side pressure port (under neck label)

Step 2: Consider housing rotation

To improve field access to wiring or to better view the optional LCD display:

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.

B. Housing rotation set screw (3/32-in.)

Note

Do not rotate the housing more than 180° without first performing a disassembly procedure (refer
to the Rosemount 4088 MultiVariable Transmitter Reference Manual [00809-0100-4088] for more
information). Over-rotation may sever the electrical connection between the sensor module and
the electronics.
