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. (Regulator

Technologies) 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.

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 orifice size is not available for Types 299HS and 299HSR.
