24-10HEATERS AND AIR CONDITIONING - Safety Precautions
SAFETY PRECAUTIONSN24PAAD
The refrigerant used in all air conditioner is R-l 2. It istransparent and colorless in both the liquid and
vapor state. Since it has a boiling point of
-29.8”C(-85.6”F).
at atmospheric pressure, it will be a vapor
at all normal temperatures and pressures. The vaporis heavier than air, non-flammable, and nonexplo-
sive. It is nonpoisonous except when it is in direct
contact with open flame. It
ia noncorrosive except
when combined with water. The following precau-
tions must be observed when handling
R-12.Caution
Wear safety goggles when servicing the refriger-ation system.
R-12 evaporates so rapidly at normal atmospheric
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 refrigera-
tion part of the air conditioning system. Keep a
bottle of sterile mineral oil handy when working on
the refrigeration system. Should any liquid re-
frigerant get into the eyes, use a few drops of
mineral oil to wash them out.
R-12 is rapidly
absorbed by the oil. Next splash the eyes with
plenty of cold water. Call your doctor immediately
even though irritation has ceased after treatment.
Caution
Do not heat
R-12 above 40°C (104°F).In most instances, moderate heat is required to
bring the pressure of the refrigerant in its container
above the pressure of the system when charging or
adding refrigerant. A bucket or large pan of hot
water not over
40°C (104°F) is all the heat required
for this purpose. Do not heat the refrigerant contain-
er with a blow torch or any other means that would
raise temperature and pressure above this tempera-ture. Do not weld or steam clean on or near the
system components or refrigerant lines.
Caution
Keep
R-12 containers upright when charging the
system.When metering
R-12 into the refrigeration system,
keep the supply tank or cans in an upright position. Ifthe refrigerant container is on its side or upside
down, liquid refrigerant will enter the system and
damage the compressor.Caution
Always work in a well-ventilated room.
‘irrGood ventilation is vital in the working area. Always
discharge the refrigerant into the service bay ex-
haust system or outside the building. Large quanti-
ties of refrigerant vapor in a small, poorly ventilated
room can displace the air and cause suffocation.
Although
R-12 vapor is normally nonpoisonous,
contact with an open flame can cause the vapor to
become very poisonous. Do not discharge large
quantities of refrigerant in an area having an open
flame. A poisonous gas is produced when using theflame-type leak detector. Avoid inhaling the fumes
from the leak detector.
Caution
Do not allow liquid refrigerant to touch bright
metal.
Refrigerant will tarnish bright metal and chrome
surfaces, and in combination with moisture can
severely corrode all metal surfaces.
R-12 Refrigerant Bundling
Refrigerant Recycling
R-12 refrigerant is a chloro-floro-carbon (CFC) that
can contribute to the depletion of the ozone layer in
the upper atmosphere.A
Ozone filters out harmful radiation from the sun.
- -/.To assist in protecting the ozone layer, Mitsubishi
Motors Corporation
recomends that a R-12 re-
frigerant recycling device that meets SAE standard
J1991 be used.
Contact an automotive service equipment supplier
for refrigerant recycling equipment that is available
in your area.
Refer to the operating instructions provided with therecycling equipment for proper operation.

24-12 HEATERS AND AIR CONDITIONING - Service Adjustment Procedures
------__--210 2352,100 Pressure
(30) (33)(299) 2&
kPa(psi)2OPOO14(3) If the sight glass is clear and the magnetic clutch is
disengaged; the clutch is faulty or, the system is out of
refrigerant. Perform low pressure switch test to determine
condition. Check low pressure switch, and clutch coil for
electrical continuity.
(4) If the sight glass shows foam or bubbles, the system could
be low on charge. Occasional foam or bubbles are normal
when the ambient temperature is above
43°C (110°F) or
below
21°C (70°F).Adjust the engine speed to 1,500 rpm. Block the air-flow
thru the condenser to increase the compressor discharge
pressure to 1,422 to 1,520
kPa (206 to 220 psi). If sight
glass still shows bubbles or foam, system charge level is
low.The refrigerant system will not be low on charge unless
there is a leak. Find and repair the leak. If the leak can be
repaired without discharging the system an oil level check
is not necessary. Use the procedure for correcting low
refrigerant level found in the Refrigerant System Service
Procedure Section.DUAL PRESSURE SWITCH
The dual-pressure switch is a combination of the low-pressureswitch (for checking the quantity of refrigerant) and the,
high-pressure switch (for prevention of overheating); it is
installed on the tube, and, when the pressure becomes
approximately 210 kPa (30 psi) or lower, the compressor stops,thus preventing the compressor from being damaged by heat.
When the pressure reaches 2,700
kPa (384 psi) or higher, the
compressor stops, thus preventing overheating. There is
generally no necessity for inspection; if, however, an unusual
condition, such as non-operation of the compressor is encoun-tered, check by following the procedures below.
(1) Check for continuity of the dual-pressure switch.
NOTEIf the air temperature drops to
0°C (32°F) or lower during
cold weather, the air conditioner will not operate (no
continuity).(2) If there is an insufficient amount of refrigerant, check the
refrigerant amount by looking through the sight glass of thereceiver; supply refrigerant if necessary.
(Refer to P.24-21.)
