Installation
Only qualified personnel shall 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.
If the regulator vents fluid 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 fluid 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 Specifications 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 fluid. To avoid such
injury and damage, install the regulator in a
safe location.
(1)(2)
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 flanged
bodies, use suitable line gaskets and approved piping and bolting
practices. Install the regulator in any position desired, unless
otherwise specified, but be sure flow through the body is in the
direction indicated by the arrow on the body.
