RegiDamper™ Installation Instructions
Application
The Arzel® RegiDamper™ is used where the branch ducts are inaccessible in nished ceilings or
in slabs, which prevent the use of the original Arzel®EzySlide™ dampers. The RegiDamper™ is
installed in the register boot just behind the register and is operated by a low pressure air and
vacuum pump (contained in the Arzel® panel) by way of a 1/4 inch plenum rated Dekoron (UL
Rated) tubing.
Installation Preparation
• Remove all registers and t damper assemblies into boots with tubing connection facing
into the duct opening (see g. 1-a).
• Once damper t is veried, remove dampers from boot.

g. 1-a - Fitting damper into boot
• Cut an opening in the main trunk large enough to view the take-offs of the runs you are zoning
with RegiDampers. Locate the opening as close to the take-offs as possible. Tape the cut
edges of the opening with duct tape to prevent cutting yourself.

Installation Procedure
Air Tube Installation
• Run a exible snake from the boot towards the main trunk. You might have to hook the end
of the snake once it enters the main duct and pull it towards the cut opening. Attach the 1/4
inch tube to the end of the snake and tape it securely. Pull the snake and tubing back
through the duct and out of the boot. Leave a ninimum of twelve (12) inches outside of the
boot and secure it to prevent it from pulling back into the duct.
• Bring each tube out of the side of the duct near the opening.
Group all like zone tubes together with tees or use the
multi-port EzyHub™ from Arzel (see Fig. 1-b). Be sure to
use a bushing (.25” ID available through Arzel) to protect the
tubing where it exits the duct.
• Run one tube per zone from the Arzel panel back to the
grouped damper tubes.
• Close the opening in the duct with a sheet petal patch and tape
or silicone for a proper air seal.
Damper Installation
• At the register boot, cut tube six (6) inches outside the oor/ceiling opening and connect to
damper actuator. (Leave the red orice in place to provide ow and quiet operation.)
• Insert the RegiDamper™ into the boot and hold damper in place with one screw on each
end (holes provided.) Do not tighten screw against end plate. This will pull damper frame
out of square and cause it to bind.
• Once damper operation is tested, secure it with rubber sealant and remove screws.
• Place register into boot. If register louvres come in contact with the RegiDamper™,
remove the louvres.
