To avoid such injury and damage, install

the regulator in a 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

be sure ow through the body is in the direction indicated

by the arrow on the body.

Note

It is important that the regulator be

installed so that the vent hole in the

spring case is unobstructed at all times.

For outdoor installations, the regulator

should be located away from vehicular

placing the regulator beneath eaves or

downspouts, and be sure it is above the

probable snow level.
