5.1 Installation conditions
Information on the conditions that must be present at the installation location in
order to ensure designated use (e.g. ambient temperature, degree of protection,
climate class etc.), and information on the device dimensions →  38
5.1.1 Orientation
No restrictions. However, self-draining in the process must be guaranteed. If there is an
opening to detect leaks at the process connection, this opening must be at the lowest
possible point.
5.1.2 Installation instructions
The immersion length of the compact thermometer can considerably influence the
accuracy. If the immersion length is too short, measurement errors can occur as a result of
heat conduction via the process connection and the vessel wall. If installing in a pipe, the
immersion length should ideally correspond to half of the pipe diameter.
Installation possibilities: pipes, tanks or other plant components.

Installation instructions EHEDG/cleanability: Lt ≤ (Dt-dt)
Installation instructions 3-A/cleanability: Lt ≤ 2(Dt-dt)
In the case of pipes with a small nominal diameter, it is advisable for the tip of the
thermometer to project well into the process so that it extends past the pipe axis.
Installation at an angle (4) could be another solution. When determining the
immersion length or installation depth all the parameters of the thermometer and of
the medium to be measured must be taken into account (e.g. flow velocity, process
pressure).

NOTICE
The following actions must be taken if a sealing ring (O-ring) or seal fails:
‣The thermometer must be removed.
‣The thread and the O-ring joint/sealing surface must be cleaned.
‣The sealing ring or seal must be replaced.
‣CIP must be performed after installation.
In the case of weld-in connections, exercise the necessary degree of care when performing
the welding work on the process side:
1. Use suitable welding material.
2. Flush-weld or weld with welding radius ≥ 3.2 mm (0.13 in).
3. Avoid crevices, folds or gaps.
4. Ensure the surface is honed and polished, Ra ≤ 0.76 µm (30 µin).

iTHERM CompactLine TM311 Installation
Endress+Hauser 15
Pay attention to the following when installing the thermometer to ensure that the
cleanability is not affected:
1. The installed sensor is suitable for CIP (cleaning in place). Cleaning is performed
together with the pipe or tank. In the case of internal tank fixtures using process
connection nozzles, it is important to ensure that the cleaning assembly directly
sprays this area so that it is cleaned properly.
2. The Varivent® couplings enable flush-mount installation.
5.1.3 General installation instructions
The device generates diagnostic message S825 if a device temperature of 100 °C is
reached due to unfavorable conditions (high process temperature, high ambient
temperature, electronics close to the process). The device generates diagnostic
message F001 or Failure current if the device temperature is 125 °C or higher.
Ambient temperature range
Ta–40 to +85 °C (–40 to +185 °F)
Process temperature range
The thermometer electronics must be protected against temperatures over 85 °C (185 °F)
by an extension neck of the appropriate length.

5.2 Installing the thermometer
Prior to installation:
1. Inspect the device for any damage caused during transportation.
2. Obvious damage must be reported immediately.

Installation iTHERM CompactLine TM311
16 Endress+Hauser
3. Pay attention to whether the thermometer may be installed directly in the process or
whether a thermowell must be used.
For detailed information, see the Technical Information
Proceed as follows to install the device:
1. The permitted loading capacity of the process connections can be found in the
relevant standards.
2. The process connection and compression fitting must comply with the maximum
specified process pressure.
3. Make sure that the device is installed and secured before applying the process
pressure.
4. Adjust the loading capacity of the thermowell to the process conditions.
5. It may be necessary to calculate the static and dynamic loading capacity.
It is possible to verify the mechanical loading capacity as a function of the installation
and process conditions using the online TW Sizing Module for thermowells in the
Endress+Hauser Applicator software →  30.
5.2.1 Cylindrical threads
NOTICE
Seals must be used for cylindrical threads.
In the case of combined thermometer and thermowell assemblies, these seals are already
installed (depending on the version ordered).
‣The system operator is required to verify the suitability of this seal with regard to the
operating conditions.

1. Replace with a suitable seal if necessary.
2. Replace the seals following disassembly.
3. As all threads must be firmly tightened, using the appropriate torques.
5.2.2 Tapered threads
‣The operator must verify if additional sealing by means of PTFE tape, hemp or an
additional welded seam, for example, is necessary in the case of NPT threads or other
tapered threads.
