Serial TH 773 and After
Section VII
Systems Description
6. The COPILOT AIR control, identical to the PILOT AIR
control, is located below the right side of the
instrument panel.
HEAT REGULATION
For maximum heat, the CABIN AIR control can be pulled
aft to reduce the volume of incoming cold air and permit
the heater to raise the temperature of the admitted air.
However,
if the CABtN AIR control is pulled aft more than
halfway
I the heater will not operate.
The volume of air available for the pilot outlet and the
copilot outlet can be divided between the two outlets as
desired by adjusting· each control individually.
More heated air
will be available for defrosting by reducing
the flow of air from the pilot outlet, copilot outlet, or both.
The PILOT AIR and COPILOT AIR controls can be used to
regulate the volume of air distributed to the rear outlets.
HEATER BLOWER
When the three-position switch on the pilot's subpanel is
placed in either the HEATER position or the BLOWER
position, the blower will operate if the landing gear is in the
extended position and the CABIN AIR control is more than
ha\fway in. The blower
win automatically shut off if the
landing gear is retracted or the CABIN AIR control is pulled
out approximately halfway.
CABIN VENTILATION
In flight, to provide unheated air for the same cabin outlets
used for heating, push the CABIN AIR and CABIN HEAT
controls forward.
