4. Install the assembled mounting frame and the lower duct
divider into the rooftop opening. Make sure the "THIS WAY
FRONT" mark is facing front (the direction of the vehicle)
while installing.
5. Fix the assembled mounting frame and lower duct divider
into the rooftop unit using 4 bolts provided. Evenly tighten
the four bolts to a torque of 40 to 50 inch pounds. This will
compress the roof gasket to approximately ½ ".
NOTE: If bolts are left loose there may not be an adequate
roof seal or if over tightened, damage may occur to the
rooftop base or mounting frame.
6. Remove the film off the double sided sticky tape found on
the top inner side of the lower duct divider.
