2006 Subaru Impreza HVAC SYSTEM (HEATER, VENTILATOR AND A/C) Workshop Service Manuals

2006 Subaru Impreza HVAC SYSTEM (HEATER, VENTILATOR AND A/C) Workshop Service Manuals. Unlike the old conventional CFC-12 system components, the cooling system components for the HFC-134a system such as the refrigerant and compressor oil are incompatible. • Vehicles with the HFC-134a system can be identified by the label (A) attached to the vehicle. Before maintenance, check which A/C system is installed in the vehicle. HFC-134a compressor oil has no compatibility with that for CFC-12 system. • Use only the manufacturer-authorized compressor oil for the HFC-134a system; only use DH-PR. • Do not mix multiple compressor oils. If CFC-12 compressor oil is used in a HFC-134a A/ C system, the compressor may become stuck due to poor lubrication, or the refrigerant may leak due to swelling of rubber parts. On the other hand, if HFC-134a compressor oil is used in a CFC-12 A/C system, the durability of the A/C system will be lowered. • HFC-134a compressor oil is very hygroscopic. When replacing or installing/removing A/C parts, immediately isolate the oil from the atmosphere using a plug or tape. In order to avoid moisture, store the oil in a container with its cap tightly closed.The CFC-12 refrigerant cannot be used in the HFC-134a A/C system. The HFC-134a refrigerant, also, cannot be used in the CFC-12 A/C system. • If an incorrect or no refrigerant is used, poor lubrication will result and the compressor itself may be damaged. The refrigerant boils at approx. -30°C (-22°F). When handling it, be sure to wear safety goggles and protective gloves. Direct contact of the refrigerant with skin may cause frostbite. If the refrigerant gets into your eye, avoid rubbing your eyes with your hands. Wash your eye with plenty of water, and receive medical treatment from an eye doctor. • Do not heat a service can. If a service can is directly heated, or put into boiling water, the inside pressure will become extremely high. This may cause the can to explode. If a service can must be warmed up, use hot water in 40°C (104°F) max. • Do not drop or impact a service can. (Observe the precautions and operation procedure described on the refrigerant can.) • When the engine is running, do not open the high-pressure valve of the manifold gauge. The high-pressure gas will back-flow resulting in an explosion of the can. • Provide good ventilation and do not work in a closed area. • In order to prevent global warning, avoid releasing HFC-134a into the atmosphere. Using a refrigerant recovery system, discharge and reuse it.
