GENERAL DESCRIPTION The heater and cooling units are combined in a single unit, which, with the mode
film damper and flow rate control valve in the heater unit, reduces ventilation
resistance, increases fan power, and decreases noise.
GENERAL SPECIFICATION SAFETY PRECAUTIONS Because R-134a refrigerant is a hydro fluorocarbon (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, Mitsubishi Motors Corporation recommends an R-134a refrigerant recycling
device.
Refrigerant R-134a is transparent and colorless in both the liquid and vapor state.
Since it has a boiling point of -29.8°C (-21.64°F) at atmospheric pressure, it will be
a vapor at all normal temperatures and pressures. The vapor is heavier than air, non-
flammable, and non-explosive. The following precautions must be observed when
handlin

WARNING:Wear safety goggles and gloves when servicing the
refrigeration system to prevent severe damage to
eyes and hands.

R-134a 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 refrigeration part of the A/C
system. Keep a bottle of sterile mineral oil handy when working on the refrigeration
system.
1. Should any liquid refrigerant get into your eyes, use a few drops of mineral oil
to wash them out.
R-134a is rapidly absorbed by the oil.
2. Next, splash your eyes with plenty of cold water.
3. Call your doctor immediately even if irritation has ceased.
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 (104.0°F) 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 temperature and pressure above this temperature. Do not
weld or steam-clean on or near the system components or refrigerant lines.
WARNING:Do not heat R-134a above 40°C (104.0°F) or it may
catch fire and explode.
CAUTION: Keep R-134a containers upright when charging the
system.
WARNING:The leak detector for R-134a should be used to
check for refrigerant gas leaks.
CAUTION: Do not allow liquid refrigerant to touch bright metal
or it will be stained.

When metering R-134a into the refrigeration system, keep the supply tank or cans
in an upright position. If the refrigerant container is on its side or upside down,
liquid refrigerant will enter the system and damage the compressor.
Refrigerant will tarnish bright metal and chrome surfaces, and in combination with
moisture can severely corrode all metal surfaces. OPERATION CONDENSER FAN AND RADIATOR FAN CONTROL For the operation of each fan, refer to
SYMPTOM CHART
.
COMPRESSOR CONTROL WHEN OPERATING THE AIR CONDITIONING SWITCH
The air thermo sensor, which senses the temperature of the air flowing out of
the evaporator, deactivates the compressor at 3°C (37.4°F) or below. The dual pressure switch turns OFF when the refrigerant pressure becomes
excessively high or low, thus protecting the compressor circuit. When the air thermo sensor is activated, and the ignition switch, blower switch,
and air conditioning switch are ON, the A/C compressor clutch relay is
energized.
WHEN OPERATING THE MODE SELECTION DIAL
The air conditioning will work when the mode selection dial is set to the
"Defroster" or "Defroster/foot" position, or the temperature control dial is set to
the "MAX A/C" position. In other dial positions, when the air conditioning
switch is turned on, the air conditioning will work.
