SECTION II
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,"
"MED" 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 obtain 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.
