In the relevant sections "Guides" we have taken extra precautions. All instructions must be read prior to system repair.
The air conditioning system uses HFC-134a refrigerant (fluorinated hydrocarbon) R134a. Always follow the instructions below.
WARNING: Only personnel familiar with the device of the system and special equipment for its filling and maintenance are allowed to service the air conditioning system. All operations must be carried out in well ventilated areas, away from sources of open flame.
CAUTION: Do not allow the refrigerant container to be heated by an open flame and do not place the container near heating appliances. Do not heat the refrigerant container above 50°C. Do not leave the refrigerant container with the lid open. Do not transport a container of refrigerant unless it is secured, especially in the trunk of a car.
WARNING: Do not smoke or weld in a room where R134a refrigerant is used. Inhalation of refrigerant vapors can cause dizziness, disorientation, incoordination, drug intoxication, motion sickness and vomiting. R134a refrigerant is colorless and odorless. Do not work with refrigerant in enclosed spaces or where it or its vapors may come into contact with open flames or hot metal. R134a is not flammable, but may form an extremely toxic gas.
CAUTION: Do not allow liquids other than R134a or special compressor oil to enter the A/C system. A sudden fire may occur.
WARNING: R134a refrigerant is a potentially hazardous liquid and can cause serious injury if not handled carefully. To work with the air conditioning system, you must have special protective clothing: heat-resistant gloves, face protection, rubber boots and a rubberized apron or special coat.
CAUTION: Due to the low boiling point, R134a refrigerant must be handled with extreme care. If R134a refrigerant comes into contact with unprotected skin, it causes instant frostbite. The bleed cylinders during bleed can also cause frostbite on the skin.
CAUTION: Do not disconnect the air conditioning hoses until the system is completely empty. Do not disconnect any air conditioning piping unless you are qualified and trained to do the job. The refrigerant used in the air conditioner can cause blindness if it comes into contact with the eyes.
CAUTION: The refrigerant must be cleaned before it is reused to ensure that the refrigerant is as pure as possible for the safe operation of the A/C system.
Preparation of refrigerant for reuse must be carried out using equipment certified by Underwriter Laboratory Inc. for compliance with the requirements of SAE J1991. If the equipment used does not meet this requirement, then there is no guarantee that the refrigerant will be purified to the required degree of purity.
The service station for air conditioning systems with R134a refrigerant must not be used to service air conditioning systems that use a different refrigerant.
R134a refrigerant, which is commercially available and intended for domestic use, is not suitable for use in a car's air conditioning system.
