The Amico Valve Combo Unit is shipped in one container holding two separate packages. One package
contains the Alarm Valve Combo. The other package contains the window and the frame assembly.
1. Recessed Valve Box: anchor the valve box rough-in to the studs so that the front edge will be flush or
slightly recessed with the finished wall. The recommended mounting is 66" (1676 mm) from the top of
the valve box to the finished floor.
NOTE:
The Shutoff Valve handles should be installed to point downstream for pressurized gases.
2. Before brazing, remove all box plugs as they could melt during 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 (outside the valve box) using brazing methods and materials in
accordance with NFPA-99 or CSA Z7396.1-06. Once valve extensions are cool, remove rags.
3. Test the system (per appropriate standards) to ensure that the intended gas and vacuum services are
connected to the appropriate lines.
WARNING: Misconnection of the gases could lead to serious or fatal injury to patients. Following the
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 (per appropriate standards)
NOTE:
Pipe sealants should comply with the requirements of NFPA 99
or CSA Z7396.1-06. Use care to exclude pipe sealants from the valve
cavity and from interior tube surfaces exposed to medical gas flow or
vacuum service. Properly applied Teflon tape is an alternative to pipe
sealants. Check Shutoff Valve handle operation for proper clearance
from gauge (if installed).
5. After the wall is finished, remove the window by pulling the ring
towards you and attach the aluminum frame to the alarm valve
combo unit valve box with the No. 6 metal screws provided. Then put
the window back in place.
