Installation

WARNING

Personal injury, property damage,

equipment damage or leakage due to



containing parts may result if this

regulator is overpressured or installed

where service conditions could exceed



section (page 2) or where conditions

exceed any ratings of the adjacent

piping or piping connections.

To avoid such injury or damage, provide



devices (as required by the appropriate

code, regulation or standard) to prevent

service conditions from exceeding limits.

Additionally, physical damage to the

regulator could cause personal injury or

property damage due to escaping gas.

To avoid such injury or damage, install

the regulator in a safe location.

1. Only personnel qualied through training and

experience shall install, operate and maintain

a regulator. For a regulator that is shipped

separately, make sure there is no damage to or

debris in the regulator. Also ensure that all tubing

and piping are clean and unobstructed.

2. Install the regulator using a straight run of pipe the

same size or larger as the regulator body. Flow

through the regulator body is indicated by the

ow arrow attached to the body. If a block valve

is required, install a full ow valve between the

regulator and the blanketed vessel. For proper

operation, the regulators should be installed with

the spring case barrel pointed down. Key numbers

referenced in this section are shown in Figures 4,

5 and 6.

WARNING

A regulator may vent some gas to the

gas service, vented gas may accumulate

and cause personal injury, death or



Vent a regulator in hazardous gas service

to a remote, safe location away from air

intakes or any hazardous area. The vent

line or stack opening must be protected

against condensation or clogging.

3. To keep the vent assembly (key 26) from being

plugged or the spring case (key 3) from collecting

moisture, corrosive chemicals or other foreign

material, point the vent down or otherwise

protect it. The diaphragm casing (key 4,

Figure 6) may be rotated in order to obtain

desired positioning.
