16 Amico Pipeline
Cylinder Bank Installation Instructions
CAUTION: This section contains important information necessary for proper installation of the
cylinder banks. Read it carefully before installing cylinder banks.
• Position the wall brackets, if required, to support the Header bars and bolt in place.
• Connect the two high pressure inlet valve / header bar assemblies to the inlet blocks on either side of the cabinet.
• Secure the Header bar assembly by tightening the union nuts onto the In-let blocks. The manifold can support
a maximum 5 x 5 staggered header bar. While the straight header bar contains a wall support bracket on every
second pipe in between each cylinder, for the staggered a support bracket is installed after every 4 – 5
cylinders, unless additional support is required.
• Remove the plug and chain assembly on each of the outlet connections on the cylinder extension bar. Attach
the cylinder pigtails to the header bar connections, while ensuring the check valves are operating in the proper
direction.
WARNING: To avoid contamination with particles or other potential hazardous materials, keep
pigtails in plastic wrapping until such time as connection to gas cylinder is planned.
When the medical gas piping system has been tested in accordance with NFPA 99, the manifold can then be connected
to it.
The outlet pipes leading from the Amico control cabinet should be connected to their respective pipeline system
connections. The connection to the relief valves should be made with a union (supplied by others) to facilitate
change, if required.
An appropriate sealing compound that is suitable for the gas being transmitted shall be used for threaded connections.
WARNING: If downstream joints near the cabinet outlet are to be silver brazed, special attention
must be given not to overheat the copper tubing, since this may alter the sealing compound
used in the threaded joints leading from the control cabinet.
