Amico Dome Loaded Manifold Nema-4 NFPA - Manual (Page 18)

18 Amico Pipeline
Testing for Leakage
Precautions
The Amico Automatic Gas Manifold`s are designed in accordance with the current revision of NFPA 99.
There are three categories of the Amico manifolds depending upon the delivery pressure. The following gas types are
available for each delivery pressure:
55 PSI Delivery Pressure
• Oxygen, Nitrous Oxide, Medical Air, Carbon Dioxide, Helium, Argon
100 PSI Delivery Pressure
• Oxygen, Medical Air, Carbon Dioxide
170 PSI Delivery Pressure
• Nitrogen, Instrument Air
Delivery (Line) Pressure - (see NOTE above)
Delivery (Line) Pressure 55 PSI 100 PSI 170 PSI
Intermediate Pressure - Ready Bank 100 PSI 200 PSI 200 PSI
Dome Bias Pressure 55 PSI ** 50 PSI 50 PSI
Intermediate Pressure - In Use Bank 150 ± 10 PSI* 250 ± 10 PSI 250 ± 10 PSI
Intermediate Relief Valve 350 PSI 350 PSI 350 PSI
Line Regulator Relief Valve 75 PSI 150 PSI 225 PSI
Maximum Inlet Pressure 3000 PSI 3000 PSI 3000 PSI
* The intermediate pressure valve of the “In Use” bank is dependent upon the dome bias pressure. Variations from the 55
PSI delivery pressure will aff ect the intermediate pressure reading.
** Same as delivery pressure.
