Utility Gas Supply Installation

Description

This section provides the utility gas supply installation requirements for the analyzer.

 Carrier Supply Gas

 Calibration Standard

 Detector Fuel Supply

 Compressed Air Supply

Refer to Application Drawing Package, Block Diagram Utility Connections sheet for analyzer

requirements.

WARNING Ensure that personnel, electrical, and local and national codes are considered for

storage, use, and handling of compressed and liquefied gasses in portable cylinders.

Carrier Supply Installation

The carrier gas is specified in the Application Drawing Package on the Block Diagram Utility Connections

sheet. See Technical Specifications on page

11 for requirements for the air supply.

Install two secured carrier gas cylinders in tandem near the analyzer mounting location. This allows

exchange of the cylinders without disrupting the carrier supply. Install carrier lines using new, clean, ¼”

(.635 cm) stainless steel tubing and fittings between the carrier gas cylinders and the analyzer. Do not

use cutting oil on the tubing. Install a check valve to prevent contamination if backpressure should occur.

Consumption

Typical carrier consumption is 180 standard cubic feet per month (5100 liters per month.)
