the basepan and slide it into the sleeve until it contacts
the rear grille. With the chassis in proper position, the
front edge of the basepan must extend out 4 ¾ inches
from the front (side) edge of sleeve.
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 9, Page 12). Make sure the gasket is installed
beginning from the lower right side corner and extend-
ing 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 foam 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.
