Prior to the installation of the pressure gauge, clean the measuring lines

thoroughly by tapping and blowing or rinsing
Protect measuring instruments from contamination and high temperature

changes!
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 and a zero point check while
the plant is running. The instruments should be protected against coarse dirt
and wide fluctuations in ambient temperature.
Correct sealing of the connections must be made using suitable flat gaskets,
■
sealing rings or WIKA profile sealings. In order to orientate the gauge so that
the on-site display can be read as well as possible, a clamp socket or union nut
should be used. When screwing on and unscrewing the pressure gauges they
should not be gripped by the case, but rather only on the spanner flats of the
connection!
