Refrigerant Coil Piping
Note: Refer to for information on handling refrigerants.
Figure 32 illustrates an example of a split-system
component arrangement. Use it to determine the proper,
relative sequence of the components in the refrigerant
lines that connect the condensing unit to an evaporator
coil. Refer to “Field-Installed Evaporator Piping
Examples,” p. 38 for more detailed schematics of
evaporator piping.
