STEP 5 CHASSIS SEAL GASKET INSTALLATION: After
installing the shell, slide the chassis into the shell stopping
approximately 3" from full insertion. Stuff the chassis seal
gasket one inch deep between the chassis and the shell
(see Figure 11). Make sure the gasket is installed beginning
from the lower right side corner and extending over the
top and down to the lower left side corner. Then push the
chassis all the way into the shell for the remaining distance
so that the plastic front meets the front edge of the shell.
If chassis seal gasket is not installed, the operation of the
unit will be negatively affected. Also, the operation noise
and outside noise will be amplified.

STEP 6 Remove the intake grille from the decorative front frame by
grasping it at the upper right and left side corners. Pull out
until the grille is released from the upper retaining snaps.
Tilt it down toward you, lift up and out of the bottom retaining
snaps. Install the decorative front frame in place over the
sleeve opening and attach it to the chassis with four sheet
metal screws as shown in Figure 11. Replace the intake
grille by positioning the bottom of the grille into the bottom
retaining snaps. Tilt the front up and away from you. Press
in lightly on top, and the grille will position itself into upper
retaining snaps.
