AIR INTAKES
CARBURETOR ICE DETECTOR
The carburetor ice detector uses an optical probe in carburetor throat below throttle valve. As ice forms
and blocks the passage of light to probe, the warning is triggered. With carburetor heat applied and ice melted
from the probe sufficiently to allow probe to sense light, the warning light will extinguish. A built-in test
switch activates light momentarily each time system is turned on, indicating system is operational.
