Installation
Duct Free Single Zone Wall Mounts are a one-to-one sys-
tem. There is a direct piping connection between the outdoor
unit and the indoor unit. Figure 25 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 Limita-
tions" section, on the previous page, for specific length
limitations in conjunction with outdoor unit and indoor unit
positioning.
• As you proceed with the piping connections be sure to adhere
to pipe support spacing lengths as shown in Figure 26 below.
Refer back to "Pipe Supports" section for in-depth information
regarding using elbows, clamps and pipe supporting materials.
• Always adhere to local codes regarding piping and accurate
support spacing along the outdoor pipe line.
