STEP 5. CHASSIS SEAL GASKET INSTALLATION: After installing the shell, slide the chassis into the shell stopping approxi-
mately 3" from full insertion. Stuff the chassis seal gasket one inch deep between the chassis and the shell (see Figure
12). 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 amplifi ed.
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 12. 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.
