The sleeve is then reinserted into the prepared opening from the outside of the building. All of the mounting flanges must contact the exterior wall. Check to see that there is enough sealant to make this joint watertight. Additional sealant must be applied as necessary. The sleeve must be centered in the opening, and the bottom of the sleeve must be checked to make certain that it is level from side to side. The bottom flange should be secured to the wall by using two screws through the holes in the bottom mounting flange of the sleeve. The sleeve must be checked to make sure that it is square in the opening. Once the sleeve is square, the side and top mounting flanges of the sleeve must be secured to the wall with screws through the holes in the flanges. The gaps between the side flanges, and the top and bottom flanges must be filled with additional sealant.

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 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.

INSTALLATION – MASONRY

CONSTRUCTION WALLS

For masonry construction walls, the dimensions for the opening will be 48-1/4 inches tall by 43-1/4 inches wide. These dimensions are plus or minus 1/4 inch and are measured from the finished floor height. See Figure 4. These will be the finish dimensions of the opening.

A 1-1/2 inch spacer needs to be installed in the bottom of the opening to raise the sleeve off the floor. Masonry blocks 1 inch thick, minimum of 6 inches wide, with 1/2 inch mortar between the block and floor will provide the required spacing. These blocks are to be laid flush with the outside wall, and must provide a water tight seal to the floor and to the opening sides. See Figure 2.

The sleeve should be test fit in the opening before final preparations are made. The sleeve will be installed into the opening from the outside of the building in. The sleeve must be centered in the opening from side to side. The mounting flanges of the sleeve must contact the outside wall all around the opening. The side and top mounting flanges must have the mounting holes drilled into the outside wall for the concrete anchors which will hold the sleeve in the wall. The holes should be drilled through the holes in the sleeve with the sleeve level and
