square in the opening. A slope is built into the bottom of the sleeve from the inside to the outside. This will allow any water that gets into the sleeve to drain out. Once the test fitting has been checked out, the sleeve should be removed from the wall.
With the sleeve removed, two 1/4 inch beads of sealant must be applied to the flanges that contact the outside wall. See Figure 3
The sleeve must be installed back in the wall making sure that the predrilled holes in the wall line up with the holes in the mounting flanges of the sleeve. Check to make sure that there is enough sealant between the wall and the flanges to make the joint watertight. Additional
sealant must be applied as required. The sleeve must be anchored to the wall. All four mounting flanges must be fastened with two fasteners each to the outside wall.
The gaps between the side flanges, and the top and bottom flanges must be sealed to the wall.
On the inside of the building, the gaps between the sleeve and the opening must be filled with insulation. This will help insulate the sleeve and prevent infiltration of any unwanted outdoor air. See Figure 5.
If the QTEC unit will be drained through the wall, the drain line must be installed through the wall. Information for the drain installation is contained in the QTEC Installation Instructions.
