1. When the water temperature is above 5 °C, when the pressure of the low pressure gauge is lower than 2 kg/cm2, it means that the refrigerant is insufficient. First, the place where the refrigerant is leaked is subjected to trapping treatment, and then the dry filter is replaced and the vacuum is refilled to fill the appropriate refrigerant.
2. When it is found that the leaking refrigerant is partially immersed in water, stop the operation of the freezer immediately, and quickly remove the water from the water tank. Inform the company to dispatch personnel to handle the repair as soon as possible to prevent the compressor from inhaling water into the system and causing more serious damage.
