General instructions

Make sure that all parts of the instrument coming in direct contact
with the process, especially the sensor element, process seal and
process fitting, are suitable for the existing process conditions, such
as 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
nameplate.
To protect the diaphragm, the process fitting is covered by a protec-
tive cap.
Remove the protective cap just before installation so that the dia-
phragm will not get damaged. It is recommended to keep the cap and
use it again later for storage or transport.
4.2

Mounting instructions

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 condi-
tion and has an undamaged diaphragm.
VEGABAR 17 functions in any installation position. It is mounted ac-
cording 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

Installation procedure

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".
