Installation
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.
1. The pressure/temperature limits in this installation guide and any applicable standard or code limitation should not be exceeded.
FLUID TYPE
SEP
1
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.
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
traffic 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.
