Front cabin heat and ventilating air is supplied by outlet holes spaced
across a cabin manifold just forward of the pilot's and copilot's feet. Rear
cabin heat and air is supplied by two ducts from the manifold, one
extending down each side of the cabin to an outlet at the front door post at
floor level. Windshield defrost air is also supplied by a duct leading from
the cabin manifold to an outlet on top of the anti-glare shield.D.clr:o.st..air.

Separate adjustable ventilators supply additional ventilation air to
the cabin. One near each upper corner of the windshield supplies air for the
pilot and copilot, and two ventilators are available for the rear cabin area
to supply air to the rear seat passengers. Each rear ventilator outlet can be
adjusted in any desired direction by moving the entire outlet to direct the
airflow up or down, and by moving a tab protruding from the center of the
outlet left or right to obtain left or right airflow. Ventilation airflow may be
closed off completely, or partially closed according to the amount of
airflow desired, by rotating an adjustment wheel adjacent to the outlet.
