LINE SET PIPING DIAGRAMS
These are two suggested examples
for running the line set from the coil
to the condensing unit. Example 1
is specifically applicable when
the system is installed with the
condensing unit below or leveled to
the coil. Example 2 is applicable
when the system is installed with
the condensing unit at a
higher elevation than the
coil.
