DESCRIPTION OF THE MANIFOLD
SHIPMENT DETAILS
The package consists of one fully tested Alert-2 Series Manifold. Optional back support bracket,
header bar assemblies, and pigtails are available.
THE COLLAPSABLE BACK BRACKET
The collapsible back bracket is designed to be shipped with the manifold, without taking up space.
The bracket will position the manifold cabinet 12” from the wall, for double cylinder spacing.
DESCRIPTION OF PARTS
The ALERT-2 economy manifold is divided into (2) main sections:
COMMON TO ALL ECONOMY MANIFOLDS
1.
PRESSURE REGULATORS
There are two types of regulators in the Amico manifold: the operating pressure regulator and
the line pressure regulator. Both types conform to NFPA 99. .
1. Operating (Source) Regulators
There are two operating regulators on every manifold, one for the left bank and one for the right
bank. For Oxygen, Nitrous Oxide, compressed Medical Air and Carbon Dioxide service, the “In
Use” regulator will be set at 200 psi and the “Reserve” regulator will be set at 120 psi . For
Nitrogen the “In Use” regulator will be set at 250 psi and the “Reserve” regulator will be set at
200 psi.
2. Line Regulators
There are also one or two line regulators on every manifold. The line regulator is capable of
maintaining a constant dynamic delivery pressure at the maximum design flow rate of the
system (factory preset to “0”). For Oxygen, Nitrous Oxide, compressed Medical Air and Carbon
Dioxide service, the line regulator(s) should be set at 55 psig [379 kPa]. For Nitrogen service,
the regulator(s) are to be set at 170 psig [1172 kPa].
2.
PRESSURE RELIEF VALVES
Pressure relief valves are installed downstream of all pressure regulators and are set at no
more than 50% above the setting of the pressure regulator located immediately upstream. All
pressure relief valves are capable of fully relieving the pressure at the set point and are upstream
of any shut-off valve.
All pressure relief valves in the manifold have piping connections to allow for connection of vent
