PIPER AIRCRAFT CORPORATION SECTION 7
PA-28-181, ARCHER IE DESCRIPTION & OPERATION
7.23 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 7-19). 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 leading edge of the wing near the
fuselage. An adjustable outlet is located on the side of the cabin near the
floor at each seat location; overhead air outlets are offered as optional
equipment. 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."
CAUTION
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.
7.25 CABIN FEATURES
For ease of entry and exit and pilot-passenger comfort, the front seats
are adjustable fore and aft. The rear seats may be removed to provide room
for bulky items. Rear seat installations incorporate leg retainers with
latching mechanisms which must be released before the rear seats can be
removed. Releasing the retainers is accomplished on earlier models by
turning the latching mechanisms 90° with a coin or screwdriver. Releasing
the retainers is accomplished on later models by depressing the plunger
behind each rear leg. Armrests are also provided for the front seats. All seats
are available with optional headrests and optional vertical adjustment may
be added to the front seats. .
A cabin interior includes a pilot storm window, two sun visors, ash trays,
two map pockets, and pockets on the backs of each front seat.
