safe location.
Clean out all pipelines before installation of the regulator and
check to be sure the regulator has not been damaged or has
collected foreign material during shipping. For NPT bodies,
apply pipe compound to the external pipe threads. For anged
bodies, use suitable line gaskets and approved piping and bolting
practices. Install the regulator in any position desired, unless
otherwise specied, but be sure ow through the body is in the
