3.5 PROCEDURE C
Redirect the louvers at the back of the wall sleeve to 60°
angle as shown in the FIG 30. The use of pliers is
recommended.
If the wall sleeve already has a rear grille, skip to step 4. If the
wall sleeve does not have a rear grille or louvered panel, install
the plastic grille from the kit. Cut the plastic grille to 26-1/2"
wide and 15-1/2" high or to the sleeve dimensions. Place the
plastic grille to the inside of the wall sleeve at the rear flange.
Fasten the 4 washer screws to secure the grille to the
wall sleeve. If you need plastic nuts to mount plastic grille
to the inside of the wall sleeve, there are plastic nuts in
the installation kit. The nuts are installed from the inside
of the sleeve and are pressed into the square holes of
the rear flanges. Fasten the bracket to the upside of the
wall sleeve using the washer screw. The bracket
prevents the unit from leaving the sleeve.
