c. Place divider plate up to bottom of air condi-
tioner base pan firmly. The foam tape on the
divider plate must seal to bottom of base pan.
See FIG. 17.
b. Remove return air cover and ceiling template
from the 3105007.XXX or 3105935.XXX kit car-
ton.
c. Locate the four 8" x 1/4" x 20 unit mounting
bolts, junction box cover and Romex connec-
tor in the 3107180.006 bolt kit.
d. Reach up into the return air opening and pull
the unit electrical cord down. Mount the junc-
tion box with screws to the framing in front of
the 14-1/4" x 14-1/4" (±1/8") opening . See FIG.
15.
e. Install the Romex connector in the junction box.
f. Hold the ceiling template up to the 14-1/4" x
14-1/4" (±1/8") opening. Be sure the large plate
faces the rear of the RV.
• Start each mounting bolt through the ceil-
ing template and up into the unit base pan
by hand. Install wood screw in each end of
the ceiling template. This insures a tight fit
of the return air cover to ceiling. See FIG.
16.
• EVENLY tighten the bolts to a torque of
40 to 50 inch pounds. This will compress
the roof gasket to approximately 1/2".
The bolts are self locking so over tight-
ening is not necessary. See FIG. 16.
