PROCEDURE B
Redirect the louvers at the back of the wall
sleeve to 60° angle as shown in the FIG 9. 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 25-
1/2" wide and 15-1/4" 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.
Remove the backing from the Horizontal

and attach that

and attach that
to the inside front of the sleeve as shown

Remove the metal rear grille and replace it with
the plastic rear grille to improve unit energy
efficiency. The plastic grille reduces the amount
of hot air discharge that recirculates through the
unit.
If the depth of your existing wall sleeve is less
than or equal to 18", skip to step 7. Otherwise,
cut the baffles and the support blocks
according to length "A" in the table below.
