Today I just want to give you a brief rundown of the Arzel air line and what makes it different from low-voltage cabling.

So if we look here, I’ve got my tubing mostly run. I’ve got a red tube here for zone 1 and a green tube for zone 2. I like to start at the far end of the duct and work my way back, adding tees as I go.

I also like to leave a small service loop. This makes it easy to disconnect dampers if needed. If I ever need to service it, I can score the tubing, cut a small section off, and reconnect without issues.

As I move through the install, I add tees and do quick inspections. If I notice a missed damper, I can easily add it using a tee, snips, and a short piece of tubing. The system uses barbed press-fit connections, so no glue or solvents are required.

Once everything is connected, I secure the tubing with zip ties and clean up the run. Then I remove slack as I continue routing the line back toward the panel.

At the panel, I also leave a service loop because removing air lines from solenoids can be difficult due to the tight barb connection. Leaving slack allows for easier servicing later by simply scoring and trimming the tubing.

There is also an installation tool kit available (part number TOOL-KIT), which includes a staple gun designed to cradle and secure the tubing to floor joists, along with fittings and screws.

One of the most important fittings used in installation is the tee fitting, which is used to build out each zone. Tees can be purchased as part of the full kit or separately under part number FIT-TT025.
