SAFETY PRECAUTIONS
ESSXAAC
<Vehicles using R-12 refrigerant >
R-12 refrigerant ischlorofluoro-carbon (CFC) that
can contribute to the depletion of the ozone layer
in the upper atmosphere
Ozone filters out harmful radiation from the sun
To assist in protecting the ozone layer, Mitsubishi
MotorsCorporationrecommendsthatR-12
refrigerant recycling device that meets SAE stand-
ard J1991 be used.
Contact an automotive service equipment supplier
for refrigerant recycling equipmentthat isavail-
able in your area:
The refrigerant used in all air conditioner is R-12
It is transparent and colourless in both liquid and
vapour state_Sincehasboilingpointof
-29.89C (-21.79F) , at atmospheric pressure, itwill
bea vapour at all normal temperatures and pres-
sures;Thevapour isheavierthanair,nonflam-
mable,and nonexplosive_It isnonpoisonousex-
cept when it is in direct contact with open flame

waterThe followingprecautionsmustbeob-
served when handling R-12_

Caution
KeepR-12 containersuprightwhencharging
the system:
When addingR-12into the refrigerationsystem
keep the supply tank or cans in an upright position; If
the refrigerant containeron its sideorupside
down, liquid refrigerantwillenter the systemand
damage the compressor
Caution
Always work inwell-ventilated room:
Good ventilation is vital in the working area
AlthoughR-12vapour is normally nonpoisonous,
contact with a open flame can cause the vapour
to become very poisonous
poisonousgasis producedwhenusingthe
flame-type leak detector .Avoid inhaling the fumes
from the leak detector.
Caution
Do not allow liquid refrigerant to touch bright
metal:
Refrigerant will tarnish brightmetalandchrome
surfaces,andin combinationwithmoisturecan
severely corrode all metal surfaces_
R-12 evaporates so rapidly at normal atmospheric
pressuresandtemperaturesthatittendsto
freeze anythingcontacts:For thisreasonex-
tremecare
must be taken to prevent any liquid
refrigerant from contacting the skin and especially
the eves: Always wear safety goggles when ser-
vicing the refrigeration part of the air conditioning
system: Keepa bottle of sterile mineral oil handy
when working on the refrigeration system. Should
any liquid refrigerantgetinto the eyes, usea few
drops of mineral oil towashthemout:R-12is
rapidly absorbed by the oil Next, splash the eyes
with plenty of cool waterCall your doctor imme-

treatment;
Caution
Do not heat R-12 above 40PC (104PF):
Inmost instances,moderateheat is requiredto
bring the pressure of the refrigerant its container
above the pressure of the system when charging
or
adding refrigerant.A bucket or large pan of hot
waternotover 40PC (104PF)isalltheheatre-
