Making the Process Connection First
The process connection is threaded onto a fitting within an adequately
supported process piping system. Use two open-end wrenches when connecting the
pressure port to a process piping system: one wrench to hold the hex flats of the pressure
connection, and the other to tighten the process fitting. Do not loosen the instrument
pressure port from the housing.
