ATTACHING CYLINDERS
The below safety guidelines should always be followed when handling compressed gas cylinders.
1. Handle cylinders carefully and only with valve caps screwed on. The cap will reduce the chance that the
cylinder valve will break off if the cylinder is accidentally dropped or falls over. The cap also protects the
cylinder valve from damage, which could cause leaky connections.
2. No smoking should be permitted near oxygen, nitrous oxide, any other oxidizer, flammable gases, or
flammable mixtures, or in areas where cylinders are stored.
3. Where an oxidizer (such as nitrous oxide or oxygen) is used, the manifold and cylinders must be kept
clean. No oil, grease, or combustible substances should come in contact with oxygen or nitrous oxide
storage or handling equipment. Such materials in contact with oxygen or nitrous oxide are readily
ignitable and, when ignited, will burn intensely.
4. Never lift gas cylinders with a magnetic lifting device.
5. Never use an open flame when leak testing.
6. Always open valves S-L-O-W-L-Y when high-pressure gases are being used.
7. Always be sure that a cylinder contains the correct gas before connecting it to any manifold.
8. Always leak-test any manifold or distribution pipeline before using.
9. Always be sure that the gas in a pipeline is the correct gas for the intended use.
10. Always close all cylinder valves before disconnecting cylinders from a manifold.
11. Always remove all empty cylinders from a manifold before connecting full cylinders.
12. Always test cylinders to be sure the cylinders are full before connecting to a manifold.
For a two cylinder manifold
–
1. Attach the flexible hoses (pigtails) to the right and left side inlet connections on the Mechanical
Enclosure as shown in Figure 2. The manifold inlets are located at the bottom of the
Mechanical Enclosure.
2. One end of the flex hose (pigtail) will connect directly to the Mechanical Enclosure and should
be wrench tight using Teflon tape as a thread sealant. The other end will have a CGA
connection with a check valve specific for the gas being used which will attach directly to the
cylinder. This is a metal-to-metal seal and no Teflon tape or other thread sealant should be
used.
