SUN TUNNEL™ Installation Instructions

Installation is a snap with new SUN TUNNEL™ Snap-Ring!
The SUN TUNNEL™ Skylight is the most versatile, affordable, and energy-efficient skylight available to contractors and homeowners. And now, Velux SUN TUNNEL™ Systems, have made adding natural light to any room in your house, even simpler by developing the 'snap-ring" installation method.

The Use of Flexible Tubing in SUN TUNNEL™ Skylights
One of the key components in The SUN TUNNEL™ Skylight system is its fully patented, flexible, reflective tubing. This tubing is similar in structural design to the tubing used for many decades in the heating and air conditioning industry and can be found in commercial businesses, high-rise buildings, hospitals, schools, and residential homes throughout North America and many other parts of the world.

SUN TUNNEL™ has taken this time-proven technology for channeling heat and cold, and added a space-age U.V.-proof liner to the inside in order to channel sunlight efficiently through attics to dark rooms all over the world. The clear dome on the roof is made from almost totally U.V. resistant materials, eliminating harmful U.V. rays before they can even reach the tubing, guaranteeing that the flexible tube will perform for many years to come.

This flexible tubing makes The SUN TUNNEL™ by far the most "user friendly" and easy-to-install tubular skylight on the market today. The ability to flex around almost any attic obstruction without the need for expensive elbows or extensions means that SUN TUNNEL™ Skylights can be efficiently and economically installed in places no other skylight can reach. Naturally, the shorter, tighter and straighter you install the tubing, the better the performance, but SUN TUNNEL™ Skylights are installed every week in hard-to-reach areas, sometimes with 90-degree bends in the tubing, and are still performing adequately.

SUN TUNNEL™ has had a strong U.S. patent on its flexible tubing since the beginning of our operations here in 1993, and is therefore the only company offering this beneficial feature with its skylights. A rigid tube skylight competitor, known as Sola-Tube, offers a 10" diameter skylight in the U.S., and openly derides The SUN TUNNEL™'s use of flexible tubing. This same company, however, uses flexible tubing with the skylights it markets in Australia, where it has proven to be a big seller for them, and is found proudly displayed in their Australian showrooms (see the upper right section of the photo.)

The new 21" diameter SUN TUNNEL™ is the largest tubular skylight on the market today and will brighten the largest rooms in your home. Just like the tubing used in our other models, our 21" flexible tube passes all ignition, flammability and smoke density testing requirements necessary to meet National Building Codes standards across the United States. We invite you to compare our SUN TUNNEL™ for brightness, ease-of-installation, and flexibility against any tubular skylight on the market. We think you'll like our quality, customer service and honesty

Installation just got easier!
The "Snap-Ring" assembly system eliminates several steps in our installation process. Now you can add natural sunlight with just a few simple steps:

1.	Install the decorative white ceiling ring and attach the patented flexi-tube.
2.	Install the roof assembly, pull the tube from the ceiling through the opening, and secure the tube with the "Snap-Ring."
3.	Slide the polished, stainless steel collar into place and attach the UV dome.
4.	Insert the prismatic light diffuser into the ceiling ring inside the room. Trim the excess tubing from the rooftop assembly.
5.	Attach the dome on the roof assembly and you're done!  Now you can start enjoying the beauty of natural light created by your own handiwork.
