The duct work and controls for the air
condition
system are made up of:
1. The air intake from beneath the rear
seat through
the filter into the evaporator air ducts.
2. Two blower motors that force the cooled
air
from the evaporator to the two grill openings
in
the package tray.
3. An individual 2-speed control for each
blower
motor.
4. Temperature control (modulator valve
control).
SAFETY PRECAUTIONS
Conditioning System. In the event that
any of the
liquid gas should get in the eyes, use
a few drops of
mineral oil to wash them out, and then
wash the eyes
clean with a weak boric acid solution.
Seek medical
aid immediately if irritation continues.
Wear Goggles
When Opening Any Fitting.
The refrigerant in the Air Conditioning
System is
always under pressure. Be-cause the system
is tightly
sealed, heat applied to any part would
cause this
pre&-sure to build up excessively.
To avoid a
dangerous explosion, never weld, use a
blow torch,
solder, steam clean or use any excessive
amount of
heat on, or in the immediate area of any
part of the
Air Conditioning System.
There are certain precautions which must
be
observed in handling and servicing the
Lincoln Air
Conditioning System. These precautions
are
necessary to protect not only the various
parts
concerned, but also the individual doing
the servicing.
Freon - 12 is nonexplosive,
nonflamable ,
noncorrosive, and
has practically no odor. It is a
safe refrigerant, however certain precautions
must be
observed while handling it.
Liquid Freon, at normal atmospheric pressures
and
temperatures, will evaporate so quickly
that it will
tend to freeze anything it comes in contact
with. For
this reason extreme care should be taken
to prevent
any quantity of the gas, in the liquid
state, from getting
on the skin or even tiny drops from getting
in the
eyes. Freon 12 is absorbed readily by
most types of
oil. For this reason it is recommended
that a bottle of
sterile mineral oil and a quantity of
boric acid be kept
near by when servicing the Air
NOTE: Before starting this procedure,
make sure
manual control is in the full cold position.
1. Open the high pressure valve, located
on the
condenser, and the low pres-sure valve,
located on the right front fender apron,
by
turning stem counterclockwise until seated.
2.
Install Pressure Test Gauge Manifold,
Tool -
ACL53-3 with both gauge valves turned
in the
full clockwise position so that the high
pressure
gauge hose is connected to the high pressure
valve service port and low pressure gauge
hose
is connected to the low pressure valve
service
port.
3.
Turn low pressure valve, located on right
front
fender apron, and high pressure valve,
located
on con denser, in the clockwise direction
1-1/2
turns. Use Tool - ACL53-5.
