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 tempera-
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 freeze
anything it contacts. For this reason, extreme care
must be taken to prevent any liquid refrigerant from
contacting the skin and especially the eyes. Always
wear safety goggles when servicing the refrigeration
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
in
its
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.
