Amico Threaded Ball-Valve - Manual (Page 4)

1. Shutoff Valves should be installed with handles pointing downstream for pressurized gases and upstream
(towards the terminal or inlet side) for vacuum.
2. Before brazing, wrap wet rags around the tube extensions next to the valves to prevent overheating and possible
damage to the valve seals. Connect copper tubing to the valve extensions using brazing materials and methods in
accordance with NFPA 99 or CSA Z7396.1. Once valve extensions are cool, remove rags.
3. Test the systems (as per appropriate standards) to ensure that the intended gas and vacuum services are
connected to the appropriate lines.
WARNING: Misconnection of gases could lead to serious or fatal injury of patients. Following initial installation of
shutoff valves, make certain that the intended services are correctly connected to the appropriate service lines.
4. Test the system for leaks (as per appropriate standards).
NOTE: Do not install the gauges before the leak test. Excessive pressure can damage the gauge. Pressure in the
system will increase or decrease with fluctuations in temperature.
If no leaks are found, gauges (purchased separately) can be installed, if required. Pipe sealants should comply with
requirements of NFPA 99 or CSA Z7396.1. Use care if applying pipe sealants. Pipe sealants should not enter the valve
cavity and interior tube surfaces that are exposed to medical gas flow and vacuum services. Properly applied Teflon tape
is an alternative to pipe sealants. Check Shutoff Valve handle operation for proper clearance from gauge (if installed).
