Installation

WARNING

Only qualied 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.

(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.

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 uid. To avoid such injury

and damage, install the regulator in a

safe location.
