If the regulator vents uid or a leak
develops in the system, it indicates that
service is required. Failure to take the
regulator out of service immediately may
create a hazardous condition.
Personal injury, equipment damage or
leakage due to escaping uid or bursting of
pressure-containing parts may result if this
regulator is overpressured or is installed
where service conditions could exceed the
limits given in the Specications section,
or where conditions exceed any ratings of
the adjacent piping or piping connections.
To avoid such injury or damage, provide
pressure-relieving or pressure-limiting
devices (as required by the appropriate
code, regulation, or standard) to prevent
service conditions from exceeding limits.
Additionally, physical damage to the
regulator could result in personal injury
and property damage due to escaping uid.
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, unless otherwise specied, but 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 trafc and positioned
so that water, ice and other foreign materials
cannot enter the spring case through the
vent. Avoid placing the regulator beneath
eaves or downspouts and be sure it is above
the probable snow level.
Installation
WARNING
!
Overpressure Protection
The recommended pressure limitations are stamped on
the regulator nameplate. Some type of overpressure
protection is needed if the actual inlet pressure
Only qualied personnel should install
or service a regulator. Regulators should
be installed, operated and maintained
in accordance with international and
applicable codes and regulations, and
Emerson Process Management Regulator
Technologies, Inc. instructions.
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.
Regulator operation below the maximum pressure
limitations does not preclude the possibility of damage from
external sources or debris in the line. The regulator should
be inspected for damage after any overpressure condition.
1. The pressure/temperature limits in this Installation Guide and any applicable standard or code limitation should not be exceeded.

Startup
The regulator is factory set at approximately the midpoint
of the spring range or the pressure requested, so an
initial adjustment may be required to give the desired
results. With proper installation completed and relief
valves properly adjusted, slowly open the upstream and
downstream shutoff valves.

27
Adjustment
To change the outlet pressure, remove the closing cap or
loosen the locknut and turn the adjusting screw clockwise
to increase outlet pressure or counterclockwise to
decrease outlet pressure. Monitor the outlet pressure with
a test gauge during the adjustment. Replace the closing
cap or tighten the locknut to maintain the desired setting.
Taking Out of Service (Shutdown)
WARNING
!
To avoid personal injury resulting from
sudden release of pressure, isolate
the regulator from all pressure before
attempting disassembly.
