PROCEDURE C
Redirect the louvers at the back of the wall
sleeve to 60° angle as shown in Figure 14.
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. 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.
