This document provides instructions for installing a flow manifold from Agilent Technologies, including plumbing gas lines to tanks, traps, and the manifold using Swagelok™ fittings for leak-tight connections. Improper connections may result in leaks, posing safety hazards and excessive gas usage. To avoid potential safety hazards, it is important to read this document before attempting to install the manifold.
This document details the procedure for installing a flow manifold into an Agilent 6890 gas chromatograph. It emphasizes safety precautions regarding flammable gases like hydrogen and outlines steps to prevent leaks during the installation of plumbing connections.
The guide covers mounting the manifold onto its bracket, securing it to the instrument, and making leak-tight Swagelok tubing connections. It also provides specific instructions for performing leak tests using electronic detectors or liquid detection fluids while protecting sensitive electronic components.

Hex nuts should be tightened by exactly 3/4 of a turn only to avoid leaks.
Assemble parts, insert tubing fully then withdraw it approximately 1–2 mm before tightening.
Insert a moisture absorbing towel between the manifold and the board to catch dripping fluid.
