Installation
Ensure that wiring conforms to all applicable local and national electrical codes and install


The process connections can be threaded onto fittings within an adequately supported
process piping system. The Lo side may be vented to atmospheric pressure.

Use two open end wrenches when connecting the pressure ports to a process piping
system: One wrench to hold the hex flats on the pressure port, the other to tighten the
process pipe or tube fittings.

Process connection pipe or tubing may be rigid or flexible.
