Systems Description
CABIN HEAT control knob - This control adjusts the thermo-
stat sensor located in the heater duct. Pulling the knob out
increases the thermostat setting to a maximum temperature of
approximately 180°F. When the duct temperature reaches the
thermostat setting, fuel is cut off to the heater.
The heater system is protected by the following items:
1. An over-temperature switch located on the aft end of the
heater which is accessible from the nose gear wheel
well. This switch will turn the heater system off if the
Heater Burner Can reaches 300°F. The switch is manu-
ally resettable from the nose gear wheel well.
2. An air pressure switch which removes power from the
ignition system and the heater fuel pump if the heater
blower or combustion air blower fails.
The distribution of the heated air is controlled by the following
controls:
1. Pilot Air control knob - This knob is located below the
pilot's subpanel. Pulling the knob out increases the air-
flow at the pilot's feet.
2. Copilot Air control knob - This knob is located below the
copilot's subpanel. Pulling the knob out increases the
airflow at the copilot's feet.
3. Defrost control knob - This knob is located below the
pilot's subpanel. Pulling the knob out increases the air-
flow to the defrost system.
The heater outlets located behind the copilot's chair and the
No. 4 passenger chair are not directly controllable. To increase
the air flow from these outlets, push in the controls for the
Pilot's Air, Copilot's Air, and Defrost.
