Piping Bundling
Gallery and wall-mounted indoor units allow for pip-
ing bundling. See Figure 41 for proper pipe and cable
bundling. Note the placement of the piping along with the
necessary insulation material.
1. Wrap each pipe with 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. Drain hose can be included within the bundled piping.
Wrap all of them together using the wider vinyl tape as
above the ground.
