Footwarmer And Demist System - BOMBARDIER Challenger 601-3A CL-600-2B16 Pilot Training Manual

FOOTWARMER
AND DEMIST SYSTEM
The system provides warm air flow to either
the rudder pedals, the windshields or both
areas simultaneously (Figure 9-9). It is inde-
pendent of the air conditioning units. It in-
volves the installation of a heating element, a
circulating fan, and associated wiring and
controls.
An electric circulation fan mounted under the
cockpit floor on the left side of the cockpit
draws air from the cockpit airflow exhaust.
This airflow is forced and directed through an
electric heating element installed in the duct-
ing behind the pilot's instrument panel.

The system is turned ON and OFF by selec-
tion of a two position switch mounted on the
temperature control panel on the right side
console (Figure 9-10). When selected to ON,
the electric fan starts the airflow. The switch
also activates the heating element. A duct tem-
perature sensor, mounted on the exhaust of
the heater, monitors the duct temperature to
keep the duct temperature within adequate
limits.
A three position diverter valve, installed just
downstream of the heater element in the duct-
ing, is manually positioned with a push/pull
linkage knob located on the copilot's side fas-
cia panel (Figure 9-11). With the knob full
forward, only the footwarmer manifold has
airflow. With the knob pulled half way, the
