■

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 uctuations in ambient temperature.

■

Correct sealing of the connections must be made using suitable at gaskets, sealing rings or WIKA prole 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 ats of the

connection!
