Installing Vertical Adapter - QuietCool QC TRI PRO-1.5X Owner's Manual

3.2 INSTALLING VERTICAL ADAPTER

A vertical wall adapter allows a damper box to be installed in the wall instead of the ceiling. A vertical
adapter is installed on the wall with the damper box mounted diagonally so the damper doors close
properly when the fan is turned off.
NOTE: Measure the studs in your wall. If they are 16" on center, you will need to follow steps 1
! !
through 4 completely. If they are wider than 16" on center, you will only need to follow steps
1 & 4.
NOTE: The damper box MUST be installed with the damper doors oriented vertically. If the damper
! !
box is mounted on the wall with the damper doors horizontally, the damper doors will not
operate correctly.
1. Note the T (TOP) side of the vertical adapter. Place the vertical adapter with the T side up onto the
damper box with the side that has only two flanges, flush on the damper box.
2. If you have studs spaced at 16" on center, you will need to remove certain
flanges on the damper box and vertical adapter. Using a flat head screw-
driver, remove the two side flanges on the vertical adapter.

4. Using the included black sharp screws, attach the vertical adapter to the damper box by screwing
them together through the two remaining flanges.
5. The vertical adapter is now installed. Go back to step 8 on page 10 and continue your installation.

3. Using a flat head screwdriver, remove the two side flanges on the
damper box. Make sure that you are removing the flanges on the
same side as the flanges you removed on the vertical adapter.
