*If more than one accessory is to be used, use the maximum dimension. If the wall thickness is more than 13¾" (35cm) - (A + ¼" [6.4 mm]), a sleeve extension must be used.

3.Drill two 3/16" holes through each side of the sleeve approximately 4" from top and 4" from bottom of sleeve. Screw four #10 x 1" screws (included) or appropriate fasteners for your installation, through the holes in the sides of the wall sleeve.

4.Apply sealant around the wall sleeve where it projects through the inside and outside wall surfaces. Apply the sealant to the screw heads or the tops of the fasteners used in Step #3.

NOTE: When sealing the sleeve on the outside of the building, be careful NOT to let the sealant block the two condensate drain holes or the four overflow slots at the bottom flange of the sleeve.

5.If the chassis and exterior grille are to be installed later, leave the weatherboard and center support in place, otherwise remove and dispose of them.

6.Provide a support lintel if the wall sleeve is installed in a concrete or masonry wall. (See Figure 7.)
