NOTE: If you are installing the damper box with a vertical adapter, please follow the
instructions on page 12.
8. Look through the hole and make sure there are no kinks or twists in the ducting. Pull the damper box
down through the hole in the ceiling.
NOTE: The QuietCool Damper Box includes removable flanges in the case that you are
installing the damper box between studs that are exactly 16” on center. To remove the
flanges, simply take a screwdriver and pry between the flange surface and the damper box.
Do this along the entire edge of the flange and it will pop off.
NOTE: The damper box flange is designed to sit on the backside of the drywall, inside the
attic. Do not attempt to install the damper box with the
flanges on the outer side of the drywall in the home.
9.
Using the included drywall screws, fasten the damper box to the
drywall and the joist in the attic.
NOTE: Remember that you must fasten the damper box
to the ceiling joists AND drywall. The purpose of this is to
make sure the damper box stays in place when you are
screwing in the grille. If you do not fasten the damper box
to the drywall, the damper box will not stay in place when
attempting to screw in the grille.
10.
Remove ceiling grille and screws from its packaging. Center
the grille over the damper box. Install the grille with the white
screws provided by screwing through the drywall into the flange
of the damper box.
NOTE: Some ceiling surfaces are uneven and may cause a small gap to be present. This can
easily be caulked later if excessive.
