6.1 Mechanical connection

In accordance with the general technical regulations for pressure gauges (e.g.
■
EN 837-2 "Selection and installation recommendations for pressure gauges").
When screwing gauges in, the force required for this must not be applied
■
through the case, but rather through the spanner flats (using a suitable tool)
provided for this purpose on the square shaft of standard connections.
Prior to the installation of the pressure gauge, clean the measuring lines
■
thoroughly by tapping and blowing or rinsing
The pressure gauge must be mounted free from vibration and should be
■
aligned so that it is easy to read. It is recommended that an isolation device is
interposed between the pressure tapping point and the pressure gauge, which
will enable the replacement of the pressure gauge while the plant is running.
The instruments should be protected against coarse dirt and wide fluctuations
in ambient temperature.

WARNING!
Before storing the instrument, any residual media must be
removed. This is of particular importance if the medium is
hazardous to health, e.g. caustic, toxic, carcinogenic, radioactive,
etc.
