4.1 General instructions

Make sure that all parts of the instrument exposed to the process, in
particular the sensor element, process seal and process fitting, are
suitable for the existing process conditions. These include above all
the process pressure, process temperature as well as the chemical
properties of the medium.
You can find the specifications in chapter "Technical data" and on the
type label.
To protect the diaphragm, the process fitting is covered by a protective
cap.
Remove the protective cap just before installation so that the
diaphragm will not get damaged. It is recommended to keep the cap
and use it again later for storage or transport.
4.2 Instructions for installation
Please check the diaphragm visually for damage and leaking fluid
before mounting and setting up the instrument. Make sure that the
diaphragm doesn't get damaged during installation.
Caution:
The instrument may only be used if it is in a technically flawless
condition and has an undamaged diaphragm.
VEGABAR 17 functions in any installation position. It is mounted
according to the same directives as a manometer (DIN EN 839-2).
Information:
We recommend using lock fittings, measuring instrument holders and
siphons from our line of accessories.
4.3 Mounting steps
For mounting VEGABAR 17, a welded socket is required. You can find
these components in the supplementary instructions manual "Welded
socket and seals".
Use the seal fitting to the instrument, or in case of NPT connections, a
high-resistance sealing material.
Screw VEGABAR 17 into the welded socket with a wrench applied to
the hexagon of the process fitting. For the proper torque see chapter
"Technical data", for spanner size see chapter "Dimensions".
