Installation
Warning
!
Only qualied 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. (Regulator
Technologies) 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 Specications
section, or where conditions exceed
any ratings of the adjacent piping or
piping connections.
1. The pressure/temperature limits in this Installation Guide and any applicable
standard or code limitation should not be exceeded.
2. For optimum performance, a pilot supply regulator may be installed in the pilot
supply tubing between the main valve and pilot.
3. This orice size is not available for Types 299HS and 299HSR.
