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. Install the regulator in any
position desired, unless otherwise specied, but be
sure ow through the body is in the direction indicated
by the arrow on the body.

assembly (key 27) installed in the 1/4 NPT spring case
vent opening. If a remote vent is required, remove the
vent assembly and install a remote vent line.

The recommended pressure limitations are stamped on
the regulator nameplate. Some type of overpressure
protection is needed if the actual inlet pressure
exceeds the maximum operating outlet pressure rating.
Overpressure protection should also be provided if the
regulator inlet pressure is greater than the safe working
pressure of the downstream equipment.
