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
4. Temperature control (modulator valve control).
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.
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
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.
