5.3.2 Piping Connections Layout
Liebert SRCs are a 1-to-1 system. There is a direct piping connection between the outdoor unit and the
indoor unit. Figure 5-13 illustrates the basic pipe connections between the outdoor and indoor unit. Refer
back to this illustration as you proceed with pipe connection. Figure 5-13 shows the indoor unit installed at
a higher position than the outdoor unit. However, if you install the outdoor unit in a higher position than the
indoor units, the basic pipe connections still apply.
Refer to Table 5-12 for specific length limitations on indoor- and outdoor-unit positioning.

NOTE
• As you proceed with the piping connections, be sure to adhere to the pipe-
support spacing as shown in Figure 5-14. Refer back to 5.2.11 - Pipe
Supports, for more information about using elbows, clamps and pipe-
support materials.
• Always follow state and local codes for piping and accurate support-
spacing along the outdoor pipe line.
