Usage Method:
1. Before use, the air valve must be checked to be a qualified product. It is strictly prohibited to use inferior air valves.
2. Ensure that the high and low pressure tubes and valves of the air valve are correctly installed at the interface with the air conditioner, and prevent the internal pressure of the tank from exceeding 1Mpa.

3. When inflated, connect the air intake tube, one end to the air conditioner, and the other end to the refrigerant tank. Push the top pin of the inflation valve down to pierce the top of the refrigerant tank, allowing the refrigerant to overflow. Then rotate the top pin of the inflation valve up to invert the refrigerant tank, allowing the refrigerant to be charged into the air conditioner.
