Installation
!
WARNING
Only qualified personnel should install
or service a switching valve. Switching
valves 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 switching valve vents fluid
or a leak develops in the system, it
indicates that service is required.
Failure to take the switching valve 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 switching valve 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.
