Alternate Air
In the event of power loss because of icing or blocking of the air filter, there is the
possibility of drawing air from the engine compartment. The ALTERNATE AIR operating
lever which serves both engines simultaneously is located under the instrument panel
to the right of the center console. To open the alternate air source the lever is pulled to
the rear. Normally, the alternate air source is closed with the lever in the forward position.
