Figure 41: Installation and Piping Connection Overview
Figure 42: Pipe Support Lengths - Outdoors
Installation
Single Zone Wall-Mounted systems are one-to-one systems. There
is a direct piping connection between the outdoor unit and the
indoor unit. Figure 41 Illustrates the basic pipe connections between
the outdoor and indoor unit. Refer back to this illustration as you
proceed with pipe connections. This illustration shows the indoor unit
being installed at a higher position than the outdoor unit. However,
should you install the outdoor unit at a higher position than the
indoor unit, the basic pipe connections should be the same.
Refer back to the tables within the “Connection Limitations”
section, on the previous page, for specific length limitations in con-
junction with outdoor unit and indoor unit positioning.

• Always adhere to local codes regarding piping and accurate
support spacing along the outdoor pipe line.
