Installation instructions
The recommendations of EN 837-2 regarding selection and installation of pressure
gauges are to be observed. Installation and commissioning may only be carried out by
trained and qualified personnel. When tightening the process connections, observe the
relevant instructions and the advice of the fittings' manufacturers. The measuring instru-
ment's central nut, which is sealed with a colour point, and the threaded connection of the
pressure gauge to the diaphragm seal must not be loosened at any rate. This would cause
the destruction of the measuring assembly and the leakage of the process medium.
