The switches are ON in the up position and OFF in the down position.

Cabin Heating and Ventilating System

Heated air and outside air are blended in a cabin manifold just aft of the
firewall by adjustment of the heat and air controls.
The temperature and volume of airflow into the cabin is controlled by the push-
pull CABIN HT and CABIN AIR control knobs.
The air is vented into the cabin from outlets in the cabin manifold near the
pilot's feet. Windshield defrost air is also supplied by a duct leading from the
manifold to the outlets below the windshield.
For cabin ventilation, pull the CABIN AIR knob out.
