WARNING

Personal injury or equipment damage,

due to bursting of pressure-containing

parts may result if this regulator is

overpressured or is installed where

service conditions could exceed the limits

on the appropriate nameplate or where

conditions exceed any rating of the

adjacent piping or piping connections.

To avoid such injury or damage, provide

pressure-relieving or pressure-limiting

devices to prevent service conditions

from exceeding those limits. Also, be sure

the installation is in compliance with all

applicable codes and regulations.

Additionally, physical damage to the

regulator could break the pilot off the

main valve, causing personal injury and

property damage due to bursting of

pressure-containing parts. To avoid such

injury and damage, install the regulator in

a safe location.

All Installations

A Type EZL regulator bleeds no gas to atmosphere

during normal operation, thus making the regulator

suitable for installation in pits and other enclosed

locations without elaborate venting systems. This

regulator also can be installed in pits subject to ooding

by venting the pilot spring case above the expected

ood level so that the pilot setting can be referenced to

atmospheric pressure.

1. Only personnel qualied through training and

experience should install, operate and maintain a

regulator. Before installation, make sure that there

is no damage to or debris in the regulator. Also,

make sure that all tubing and piping are clean

and unobstructed.
