Installation
Ensure that wiring conforms to all applicable local and national electrical codes and install
unit(s) according to relevant national and local safety codes.
Normally, line mounting provides adequate support for the instrument.
1st Step: Make the Process Connection

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 process fitting, the other at the hex flat to tighten the
electronic pressure switch-transmitter.

Process connection pipe or tubing may be rigid or flexible.
NOTE: Do not use the 1/2” NPT(M) connection on pressures higher than 5000 psi.
