Installation
1
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.
