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.
