AND VENTILATION General Information
SAFETY PRECAUTIONS
Because R-l refrigerant is a, hydrofluorocarbon
(HFC) which contains hydrogen atoms in place of
chlorine atoms, it will not cause damage to the
ozone layer.
Ozone filters out harmful radiation from the sun.
To assist in protecting the ozone layer, Chrysler
Corporation recommends an R-l refrigerant re-
cycling device.
Refrigerant R-l is transparent and colorless
in both the liquid and vapor state. Since it has
a boiling point of at atmospher-
ic pressure, it will be a vapor at all normal tempe ra-
tures and pressures. The vapor is heavier than
air, non-flammable, and nonexplosive. The follow-
ing precautions must be observed when handling
R-l
Caution
Wear safety goggles when servicing the refrig-
eration system.
R-l evaporates so rapidly at normal atmospher-
ic pressures and temperatures that it tends to free ze
anything it contacts. For this reason, extreme care
must be taken to prevent any liquid refrigerant fro m
contacting the skin and especially the eyes. Always
wear safety goggles when servicing the refrigeratio n
part of the A/C system. Keep a bottle of sterile
mineral oil handy when working on the refrigeration
system. Should any liquid refrigerant get into the
eyes, use a few drops of mineral oil to wash them
out. is rapidly absorbed by the oil. Next
splash the eyes with plenty of cool water. Call your
doctor immediately even though irritation has
ceased after treatment.
Caution
Do not heat above
In most instances, moderate heat is required to
bring the pressure of the refrigerant inits
above the pressure of the system when charging
or adding refrigerant.
A bucket or large pan of hot water
over
is all the heat required for this purpose.
Do not heat the refrigerant container with a blow
torch or any other means that would raise tempera-
ture and pressure above this temperature. Do not
weld or steam clean on or near the system compo-
nents or refrigerant lines.
Caution
Keep
containers upright when charging
the system.
When adding into the refrigeration system
keep the supply tank or cans in an upright
position.
If the refrigerant container is on its or upside
down, liquid refrigerant will enter the
damage the compressor.
Caution
1.A leak detector designed
be used to check refrigerant gas
2.Do not allow liquid refrigerant to
metal.
Refrigerant will tarnish bright metal and chrome
surfaces, and in combination with moisture can
severely corrode all metal surfaces.

REFILLING OFOIL IN THE A/C SYSTEM
Too little oil will provide inadequate compressor l ubrication
and cause a compressor failure. Too much oil will i ncrease

through the entire system by the refrigerant. Some of this
oil will be trapped and retained in various parts of the system.

COMPRESSOR NOISE CHECK
You must first know the conditions when the noise occurs. These conditions are: weather, vehicle speed,
in gear or neutral, engine temperature or any other special conditions.
Noises that develop during A/C operation can often be misleading. For example: what sounds like a
failed front bearing or connecting rod, may be caus ed by loose bolts, nuts, mounting brackets, or a
loose clutch assembly. Verify accessory drive belt tension (power steering or generator).
Improper accessory drive belt tension can cause a m isleading noise when the compressor is engaged
and little or no noise when the compressor is disen gaged.
Drive belts are speed-sensitive. That is, at differ ent engine speeds, and depending upon belt tension,
belts can develop unusual noises that are often mis taken for mechanical problems within the compressor .
ADJUSTMENT
1. Select a quiet area for testing. Duplicate conditions as much as possible. Switch compressor on
and off several times to clearly identify compresso r noise. To duplicate high ambient
head pressure), restrict air flow through condenser . Install manifold gauge set sure discharge
pressure doesn’t exceed 2,070 (300 psi).
2. Tighten all compressor mounting bolts, clutch mo unting bolt, and compressor drive belt. Check to
assure clutch coil is tight (no rotation or wobble) .
3. Check refrigerant hoses for rubbing or interfere nce that can cause unusual noises.
4. Check refrigerant charge. (Refer to
5. Recheck compressor noise as in Step 1.
6. If noise still exists, loosen compressor mountin g bolts and retorque. Repeat Step 1.
7. If noise continues, replace compressor and repea t Step 1.
