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