9. CRITICAL STEP: Move the Fresh Air Flap fully closed and pry it so that it lines up with the "V" shaped opening in the right half of the unit. (The "V" is shown in photo 66, and prying techniques are shown in photos 67 and 68) If the flap is not in line with the "V" channel, the halves will not come apart, and you risk damaging the flap.
