Installation of Valve Boxes
The Amico Valve Box is shipped in one container holding two separate packages. One package contains the valve box,
valves and gauges (if required). The other package contains the window and the frame assembly.
1. Recessed Valve Box: The rough-in of the valve box arrives with a cardboard shield covering its front. You will need
to remove the cardboard shield to install the rough-in and perform the pressure test, but it should be repositioned
to protect the valves while the walls are being finished. 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 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. Once valve extensions are cool, remove rags.
3. Test the system (as 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 of 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 (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, install gauges (if required). Pipe sealants should comply with the 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).
5. Mark the areas controlled by each valve on the labels enclosed. Attach the labels to the label holders.
WARNING: Make certain that the proper label coincides with the valve it describes and is positioned on the label
holder so that it can be easily read.
6. Recessed Valve Boxes: After the wall is finished, remove the cardboard shield (keep screws). Remove the window
by pulling the ring towards you and attach the aluminum frame to the valve box with the No. 6 metal screws
provided. Then put the window back in place.
