1.Adding method, filling the low pressure end of the compressor. This method has a slower filling speed. Generally, the supplementary method is used when the refrigerant is insufficient. Operation steps: need to start the car, turn on the air conditioner, and then add refrigerant gas, the snow tank is set.<br> 2.Fully filled, this method is safe and fast, and is suitable for the first filling of refrigerant in the refrigeration system (the refrigerant tank is inverted).<br> 3.Operation steps: Do not turn on the air conditioner after vacuuming, and directly add liquid refrigerant from the high-pressure end (the refrigerant tank is upright). Fill the refrigerant from the low pressure side, start the engine, and turn the air conditioner (the refrigerant tank is upright).<br> Notice:<br> 1.Do not store empty cans in places where corrosive gas is burned or pressurized. Empty cans cannot be reused.<br> 2.Wear glasses during surgery. If it accidentally splashes into the eyes or skin, rinse immediately with plenty of water.<br> 3.Aim the bottom of the tank at the human body during operation.<br> The maximum internal pressure of the container is 15 MPa. When opening the air conditioner compressor, be sure to tighten the high-pressure end of the fluorinator or do not connect it to the high-pressure to avoid high-pressure gas explosion.<br> 5.The storage temperature should not be too high or too low, and avoid direct sunlight.<br> 6.Put the can on the engine or radiator and avoid direct sunlight.<br> 7.The storage temperature is lower than 40 DegreeC.<br> 8.Don't shake the jar vigorously.<br> 9.This product is a high-pressure liquefied gas, which should be operated by professional and technical personnel to avoid injury.<br> 1.Material: Car refrigerant<br> 2.Capacity: about 180g<br> Package List:<br> 1*Car Air Conditioning Refrigerant<br> Note: Due to the light and screen setting difference, the item's color may be slightly different from the pictures.
