CABIN HEATING – DESCRIPTION AND OPERATION
The cold air is introduced in the system through an air inlet (Item no. 1 Figure. 1). Cold air is
heated between the heat exchanger (item 2) located on engine muffler. Heated air is directed
toward two ways:
1. Carburetor heat (item 4), through the air-box (item 3);
2. Defrost/Cabin heat through an hot air valve (item 5; Figure . 4) that open (or close) the air
flow to windshield defrost (item 6) and to cabin heat (item 7).
Both systems are operable from the instruments panel, carburettor heat command lever
(Figure 2.) is located in the central side of the instruments panel, near the throttle lever; cabin
heat/defrost knob (Figure 3.) is located in the right lower side of instrument panel.
