Usage of refrigerant
Avoid breathing in air conditioning refrigerant or lubricant vapor， which may irritate eyes, nose and throat. Besides, as to environmental concerns, we suggest that recovery/ recycling/ recharging equipments should be used for draining r-134a from the air conditioning system. If accidental system leakage occurs, ventilate working area before resuming a/c.
Don’t perform pressure or leakage test on r-134a service equipment and vehicle air conditioning system with compressed air. Mixtures of air and r-134a have been proved to be combustible under pressurized condition. These mixtures, if ignited, may cause injury or property loss. Additional health and safety information on operation may be obtained from refrigerant manufacturers.
Do not let refrigerant leak near flaming fire or any kind of heat. A poisonous gas may be generated if the refrigerant gas contacts fire or heat sources such as lighted cigarettes or heaters. When carrying out any operation that may cause refrigerant leakage, extinguish or remove the above-mentioned heat sources and maintain adequate ventilation.
Using liquid refrigerant is dangerous. A small quantity on the skin can result in local frostbite. When handling the refrigerant, wear gloves and safety goggles. If refrigerant splashes into eyes, immediately wash it and consult a doctor.
Storage of refrigerant
The refrigerant container is highly pressurized. High temperature may cause explosion, resulting in scattering metal fragments and liquid refrigerant that shall cause serious injury. Refrigerant should be
stored below 40℃ (104 f).
Application of compressor oil
Only pag56 compressor oil is allowed for this model. Using of other compressor oils may damage the a/c compressor.
Do not spill pag56 compressor oil on the vehicle. Drops of compressor oil on the vehicle surface may corrode the finishing paint. If oil drops on the vehicle, wipe it dry immediately.
Pag56 or equivalent compressor oil has higher rate of moisture absorption than the previously used mineral oil. If moisture is mixed with the compressor oil, the cooling system could be damaged. Therefore, install caps immediately after using the compressor oil or removing cooling
