Amico Dome Loaded Manifold NFPA - Manual (Page 6)

6 Amico Pipeline
Description of the Manifold
SHIPMENT DETAILS
The Manifold system may be shipped in more than one carton, depending on the number of cylinder connections. The
main carton contains the following items:
• Manifold control panel (with power supply assembly)
• Wall mounting bracket (attached to manifold control panel)
• 3/4” Source shut-off valve
• Installation, Operation and Service Manual
Additional cartons may contain appropriate number of headers and cylinder pigtail assemblies. As standard, header
assemblies are configured so cylinder inlets are on 11-inch centers. Cylinders may be placed in a double row “staggered” or
single row “straight” configuration. Cylinder inlets closest to the manifold control panel are intended for cylinders
placed directly beneath the manifold control panel. Pigtails for gases other than oxygen and helium are 36” stain-
less-steel flexible type. Oxygen and helium pigtails are rigid copper and are pre-bent to approximate shape for connection
to the cylinders. The manifold is designed to be mounted directly to a wall.
THE MANIFOLD ENCLOSURE
The manifold enclosure contains a switch mode power supply that can handle voltage from 110-240 vac with a built-in
fuse and terminal block. The enclosure on this manifold is NEMA-1 (general purpose applications only). This cabinet
must not be mounted outdoors.
The manifold also has a latched door that is easy to remove. The pre-assembled circuit board is located on the center of
the enclosure with a hinge mounting bracket. This design will reduce installation time and eliminate the risk of improper
installation, since all the components of the manifold are connected and tested at the factory.
HEADER BAR WALL SUPPORT BRACKET
The manifold can support, at maximum, a 5x5 staggered header bar. While the
straight header bar contains a wall support bracket on every second pipe in
between each cylinder, a standard staggered header bar has a wall support
bracket in place after every 5 cylinders, unless additional support is requested.
MANIFOLD DISPLAY BOARD
The LED’s on the front of the Manifold indicate the status of the gas supply. The primary bank will indicate In-Use (with
the Green LED turned on) and the reserve / secondary indicating Ready (with the Yellow LED turned on) or Empty (Red
LED turned on) depending on the status of gas. When the primary bank of cylinders is depleted, the manifold will
automatically switch to the secondary bank of cylinders without interruption of gas flow to the facility. The Red LED will
illuminate when a bank is depleted and two normally closed dry contacts will open. One or both sets of contacts may
be wired to an external alarm, remote buzzer and/or a building management system.
