Chilled Water Piping
Chilled water coils are provided without valves for field
piping, or piped with three-way valves with motor actuators.
Table 10
provides information on units with factory installed
piping and valve packages. The table also provides field sweat
connection information for units not furnished with factory
installed piping and valve packages.
With the factory piping and valve package, the coil assembly is
controlled through a single three-way valve. When two coils
are included in the assembly, they are piped in parallel. Field
connections are male NPT, sized as shown in
to
