Installation
!
WARNING
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.
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
1. The pressure/temperature limits in this installation guide and any applicable standard or code limitation should not be exceeded.
