4-3.7 Installation of Valve Outlet Adapter
Always connect a valve outlet adapter into system piping (union connection)
before connecting to an HFC-227ea cylinder.
WARNING
Install valve outlet adapter (P/Ns WK-283904-000, WK-283905-000, and WK-283906-000) in
system piping. Tighten securely and continue with threaded rigid pipe. A union needs to be
installed for ease of disconnecting the cylinder. Use check valves for connecting multiple
cylinders on to manifold.
Note: A groove-groove fitting is used in place of a valve outlet adapter for the 3-inch valve
and associated cylinders.

Attach the flexible discharge hose from system piping or El-check in the discharge manifold to
the cylinder valve. Tighten securely. See Figure 4-9 and Table 4-9 and Table 4-10.
Always connect the flexible discharge hose into system piping before
connecting to an HFC-227ea cylinder.
