Personnel: Skilled personnel
WARNING!
Physical injuries and damage to property and the
environment caused by hazardous media
Upon contact with hazardous media (e.g. with ammable
or toxic substances), harmful media (e.g. corrosive, toxic,
carcinogenic, radioactive), there is a danger of physical
injuries and damage to property and the environment.
Hazardous media with extremely high temperature and
under high pressure may be present at the instrument.
▶For these media, in addition to all standard regula-
tions, the appropriate existing codes or regulations
must also be followed.
▶Wear the requisite protective equipment (see chapter
3.5 “Personal protective equipment”)
WARNING!
Physical injuries and damage to property and the
environment caused by media escaping under high
pressure
With the pressurisation of the instrument, as a result of
poor sealing of the process connection, media under
high pressure can escape.
Due to the high energy of the media that can escape in
the event of a failure, the possibility of physical injuries
and damage to property exists.
▶The sealing of the process connection must be
carried out expertly and checked for leak tightness.

WARNING!
Physical injuries and damage to property and the
environment caused by components blowing out in
the event of a failure
In the event of a failure, either the plug of the blow-out
device or, in case of instruments with safety version “S3”,
the entire case back is ejected.
Due to the high energy of the components blown out in
the event of a failure and the media that can subsequent-
ly escape, the possibility of physical injuries and damage
to property exists.
▶It must be ensured, e.g. by suitable protective devices
or sucient distance, that in the event of a failure
neither personal injury nor damage to property or the
environment can occur.
5.1 Requirements for the installation location
If the line to the measuring instrument is not adequately stable, an
instrument mounting bracket should be used for fastening.
If vibrations cannot be avoided by means of suitable installation,
instruments with case lling should be used.
For outdoor applications, the selected installation location has to
be suitable for the specied ingress protection, so that the instru-
ment is not exposed to impermissible weather conditions.
In order to avoid any additional heating, the instruments must not
be exposed to direct solar irradiation while in operation!
To ensure that the pressure can be safely vented in the case of a
failure, a minimum distance of 20 mm [7.9"] from any object must
be maintained.
5.2 Mounting
After unpacking the instrument, a visual inspection for damage
(e.g. pointer, threads, sealing face, pressure port) must be carried
out.

5. Commissioning, operation
Depending on the application, ll the instrument with the medium
before screwing it in, in order to ensure it functions properly.
Mounting is only permitted in the depressurised state. Reliably
depressurise the instrument using the available valves and protec-
tive devices (e.g. shut-o valve, monoange).
Nominal position per EN 837-3 / 9.6.6 image 7: 90° ±5° ( ⊥ ), if not
stated otherwise in the order documentation.
With parallel male threads (e.g. G ½ B), use at gaskets, lens-type
sealing rings or WIKA prole sealings.
With tapered threads (e.g. NPT threads), the sealing is made in
the thread, using suitable sealing material (EN 837-2).
When screwing the instruments in, the force required for sealing
must not be applied through the case, but only through the
spanner ats provided for this purpose, and using a suitable tool.
The tightening torque is dependent on the selected process
connection.
