Mitsubishi Outlander: General Information, Specifications
General Information
The blower, heater, and evaporator have been integrated with the heater and A/C system to achieve greater fan power and noise reduction.
SAFETY PRECAUTIONS
WARNING Wear safety goggles and gloves when servicing the refrigeration system to prevent severe damage to eyes and hands.
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 −29.8ºC (−21.64ºF) 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 handling R-134a.
WARNING Do not heat R-134a above 40ºC (104.0ºF) or it may catch fire and explode.
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.
CAUTION Keep R-134a containers upright when charging the system.
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 40ºC (104.0ºF) 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 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
The ECM judges the required revolution speed of radiator fan motor and condenser fan motor using the input signals transmitted from A/C switch, output shaft speed sensor and engine coolant temperature sensor.
COMPRESSOR CONTROL
When operating the A/C switch
- The fin thermo sensor, which senses the temperature of the air flowing out of the evaporator directly, deactivates the compressor at 1ºC (33.8ºF) or below.
- The A/C pressure sensor turns OFF when the refrigerant pressure becomes excessively high or low, thus protecting the compressor circuit (See Table below).
- When the air thermo sensor is activated, and the ignition switch, blower switch, and A/C switch are ON, the A/C compressor clutch relay is energized.
When operating the mode selection dial
- The A/C will work when automatically the mode selection dial is set to the "Defroster" or "Defroster/foot" position, or the temperature control dial is set to the "MAXIMUM A/C" position. In other dial positions, when the A/C switch is turned on, the A/C will work.
