Installation
Single Zone Vertical Air Handling Unit systems are one-to-one sys-
tems. There is a direct piping connection between the outdoor unit
and the indoor unit.
Refer back to the tables within the "Connection Limitations" section
for specific length limitations in conjunction with outdoor unit and
indoor unit positioning.
• When proceeding with piping connections, be sure to adhere to pipe
support spacing lengths as shown in the figure 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.
• Always include plenty of insulation on all refrigerant and drain piping
to ensure condensate does not form and cause damage to walls,
floors, etc.
Pipe Bundling
See the figure at right for proper pipe and cable bundling. Note the place-
ment of the piping along with the necessary insulation material.
1. Wrap each pipe with plenty of the proper insulation material.
2. Secure the piping by wrapping vinyl tape around the pipe.
• Use the narrow size tape for wrapping the actual pipe.
3. Include the drain hose within the bundled piping, and wrap all of them
together using the wider vinyl tape as shown in the figure.
• The end of the drain hose outlet must be routed above the ground.
Always include plenty of insulation on all refrigerant and drain piping to ensure condensate does not form and cause damage to walls, floors, etc.
