PA-28-181, ARCHER III
7.27 HEATING AND VENTILATING SYSTEM
Heat for the cabin interior and the defroster system is provided by a heater
muff attached to the exhaust system (Figure 7-12). The amount of heat desired
can be regulated with the controls located on the far right side of the instrument
panel.
The air flow can be regulated between the front and rear seats by levers
located on top of the heat ducts next to the console.
Fresh air inlets are located in the inboard portion of the leading edge of the
wing near and in the aft portion of the fuselage. Adjustable outlets are located
on the side of the cabin near the floor and overhead on the ceiling at each seat
location. Air is exhausted through an outlet under the rear seat. A cabin air
blower, incorporated in the ventilating system, is also available as optional
equipment. An optional overhead ventilating system with a cabin air blower is
available on models without air conditioning. This blower is operated by a FAN
switch with 3 positions - "OFF," "LOW," "HIGH."
When cabin heat is operated, heat duct surface
becomes hot. This could result in burns if arms
or legs are placed too close to heat duct outlets
or surface.
