The process of filling the refrigerator can be achieved by the following steps:
Turn off the power to the refrigerator to ensure safe power failure.
Open the refrigerator door to allow air to circulate inside.
Place a thermometer inside the refrigerator to ensure that it can measure the temperature inside the refrigerator.
Place an ice cube in the refrigerator and close the door.
Wait for some time until the temperature inside the refrigerator becomes very cold, which usually takes several hours.
Check the thermometer to make sure the temperature inside the refrigerator has reached the desired temperature, if not, you can continue to wait for a while.
When the desired temperature is reached, you can remove the ice, then close the refrigerator door and turn the power back on to keep the refrigerator cold.
Please note that during the cooling process, be sure to ensure the air circulation inside the refrigerator, and pay attention to safety, do not put flammable items in the refrigerator. In addition, the time it takes to fill the refrigerator will also be affected by the size and model of the refrigerator.
Quantitative charging method. Quantitative charging method is to use a special refrigerant quantitative filling device to charge refrigerant according to the refrigerant injection amount specified on the refrigerator nameplate. Refrigerator refrigerant charging is generally not used quantitative charging method, although this method is fast to charge refrigerant, but at present can only be used to charge R12 refrigerant, and to unplug the refrigerator power.

Weighing and charging method. Weighing and charging method is to use a high-precision electronic scale with a minimum measurement unit of 1g to charge refrigerant to the refrigerator according to the refrigeration dose marked on the refrigerator nameplate. This method is mostly used for refrigerators requiring high accuracy of filling refrigeration dose (such as refrigerators using R134a and R600a refrigerants), and the filling refrigeration dose should not exceed ±5g of the error of the refrigerator's nominal value.
1. Pour the cooling liquid into the cooling liquid filling port, which is usually located at the bottom or top of the refrigerator.
2. Use a tool, such as a syringe or extruder, to inject the cooling liquid into the injection port. Ensure that the amount of refrigerant injected is accurate.
3. After filling, gently shake the refrigerator to ensure that the cooling liquid is evenly distributed.
4. If necessary, use tools such as a scale or thermometer to measure the position and depth of the filling port.
5. Ensure that the inside of the refrigerator is dry to avoid leakage or evaporation of refrigeration liquid.
Please note that when using refrigeration fluid, follow the manufacturer's instructions and pay attention to the brand and type of refrigeration fluid to avoid the use of inappropriate refrigeration fluid, which can cause failure or damage to the refrigerator.

Can not add it yourself, because the refrigerator filling refrigeration liquid is very troublesome, and requires a lot of professional knowledge and operational experience to complete.
First of all, the refrigerator is filled with refrigeration liquid, to remove the original process pipe, completely discharge the original refrigerant, weld a new process pipe or needle valve at the position of the process pipe, and then fill the refrigeration system pipeline with high pressure gas leak detection, leak repair, vacuum and add standard refrigerant. This process is relatively complex and professional
