Factory Installed Piping Packages
Trane has the ability to factory mount piping packages to hydronic coil
selections when ordering TUC, Tracer ZN520, pneumatic, or end-device
controls. (Note: Valves for steam coils are not factory piped.)
Piping packages are available in either 2-way, or 3-way configurations.
The 3-point floating valve is piped on the return side of the coil. Piping
packages are factory leak tested to 90 psig to ensure joint integrity.
(Note: Insulation for the piping packages is field provided and field in-
stalled.)
See Figure 21 for typical piping package.
