Keep all cylinders and manifolds away from any source of high temperature over 10°F (50°C) or possible fire hazards.

High-pressure gas contained in a closed cylinder becomes increasingly dangerous when exposed to high temperature

because pressure increases and the strength of the cylinder decreases. Manifolds installed in open locations should be

protected from weather conditions. During winter, protect the manifold from ice and snow. In summer, shade the

manifold and cylinders from continuous exposure to direct sunlight. Always leave access to the manifold for cylinder

replacement. Always secure cylinders, whether in use or in reserve.

LOCATION

The site chosen for the manifold installation shall be level, well ventilated, and at a safe distance from sources of

flames, sparks, and excessive heat. The manifold should not be placed in an area that may subject the manifold to

damage from passing trucks, cranes, or other heavy machines. Oxygen manifolds must not be installed under shafting,

belting, or other places where oil can drip on them. Under no circumstances should liquid product be allowed into

the hoses or manifold. For other location guidelines, see NFPA Standard 50 and 51.

INSTALLATION

Installing the system:

1. Be sure to consider all factors when selecting materials.

. Do not use oil or grease on fittings.

3. Be sure that all fittings are secure and leak tight. PTFE tape should be used on pipe threads as illustrated in

Figure1.

4. Purge devices: These devices can be purchased as accessories. Purge devices are used to remove toxic, corrosive,

or flammable gases from the customer's system to a safe discharge area. This is particularly helpful when an

internal problem occurs (such as regulator malfunction).
