Only NEW, moisture-free refrigerant oil should be used in the air conditioning system. This oil is highly refined and dehydrated so moisture content is less than 10 parts per million. The oil container must be tightly closed at all times when not in use, or moisture from the air will be absorbed into the refrigerant oil. SERVICING PRECAUTIONS DISCHARGING SYSTEM Discharge A/C system, using approved refrigerant recovery/recycling equipment that meets SAE J2210 requirements. Always follow recovery/recycling equipment manufacturer’s instructions. After refrigerant recovery process is completed, replace any refrigerant oil removed with the same amount of NEW refrigerant oil. DISCONNECTING LINES & FITTINGS After system is discharged, carefully clean area around all fittings to be opened. Always use 2 wrenches when tightening or loosening fittings. Some refrigerant lines are connected with a coupling. Special tools may be required to disconnect lines. Cap or plug all openings as soon as lines are removed. DO NOT remove shipping caps from replacement components until ready to install. CONNECTING LINES & FITTINGS NOTE: Ensure all replacement component connections match connections of system being worked on. Always use a NEW gasket or "O" ring when connecting lines or fittings. Coat "O" ring with NEW refrigerant oil and ensure it is not twisted during installation. Always use two wrenches to prevent damage to lines and fittings. PLACING SYSTEM IN OPERATION After component service or replacement has been completed and all connections have been made, thoroughly evacuate system with a vacuum pump. Charge system with proper amount of refrigerant and perform leak test. See REFRIGERANT OIL & REFRIGERANT SPECIFICATIONS table for system capacities. Ensure there are no leaks at any fitting that has been opened. After system has been leak tested, check system performance. NIPPONDENSO 10-CYL. Eclipse 2.0L Non-Turbo & Montero Replacement compressor is shipped with NEW refrigerant oil. Drain, measure and discard refrigerant oil from old compressor. Drain NEW refrigerant oil from replacement compressor equal to difference between amount drained from old compressor and amount shipped in replacement compressor. If any other components are replaced, add NEW refrigerant oil as specified. See COMPONENT REFRIGERANT OIL CAPACITIES (MITSUBISHI - NIPPONDENSO 10-CYL.) table.
