DESCRIPTION
&
OPERATION
PA-28-181,
ARCHER
II
Located
inboard
of
the
temperature
control
is
the
fan
speed
switch
and
the
air
conditioning
ON-OFF
switch.
The
fan
can
be
operated
independently
of
the
air
conditioning.
However,
it
must
be
on
for
air
conditioner
operation.
Turning
either
switch
off
will
disengage
the
compressor
clutch
and
retract
the
condenser
door.
Cooling
air
should
be
felt
within
one
minute
after
the
air
conditioner
is
turned
on.
NOTE
If
the
system
is
not
operating
in
5
minutes,
turn
the
system
OFF
until
the
fault
is
corrected.
The
FAN
switch
allows
operation
of
the
fan
with
the
air
conditioner
turned
OFF
to
aid
cabin
air
circulation
if
desired.
A
LOW
or
HIGH
flow
of
air
can
be
selected
to
the
air
conditioner
outlets
located
in
the
overhead
duct.
The
outlets
can
be
adjusted
or
turned
off
by
each
occupant
to
regulate
individual
cooling
effect.
The
“DOOR
OPEN?”
indicator
light
is
located
to
the
left
of
the
radio
stack
in
front
of
the
pilot.
The
light
illuminates
whenever
the
condenser
door
is
open
and
remains
on
until
the
door
is
closed.
A
circuit
breaker
located
on
the
circuit
breaker
panel
protects
the
air
conditioning
electrical
system.
Whenever
the
throttle
is
in
the
full
throttle
position,
it
actuates
a
micro
switch
which
disengages
the
compressor
and
retracts
the
scoop.
This
is
done
to
obtain
maximum
power
and
maximum
rate
of
climb.
The
fan
continues
to
operate
and
the
air
will
remain
cool
for
approximately
one
minute.
When
the
throttle
is
retarded
approximately
1/4
inch,
the
clutch
will
engage
and
the
scoop
will
extend,
again
supplying
cool,
dry
air.
7.35 PIPER EXTERNAL POWER*
An
optional
starting
installation
known
as
Piper
External
Power
(PEP)
is
accessible
through
a
receptacle
located
on
the
right
side
of
the
fuselage
aft
of
the
wing.
An
external
battery
can
be
connected
to
the
socket,
thus
allowing
the
operator
to
crank
the
engine
without
having
to
gain
access
to
the
airplane’s
battery.
