Installation
Procedure B
1. 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.
2. 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.
3. 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.
4. Remove the backing from the Horizontal Insulation

and attach that to the inside bot-

and attach that to the inside front of the sleeve
as shown below.
5. 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 dis-
charge that recirculates through the unit.
6. 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.
