How to add fluoride to the ice machine?

The specific amount of fluorine added to the ice machine depends on the model of the machine. Different models add different types and weights of refrigerants. Generally, 500g to 1000g is enough. After confirming that there is nothing, you can start vacuuming and prepare for adding fluoride. 2. If it is an internal leakage problem, copper pipe coils are generally required, but this kind of maintenance is expensive. You should consult the price before the maintenance before considering whether it needs to be repaired. 3. The step of adding fluorine to the ice machine, firstly fill the evacuated ice machine with a combination meter valve at the process port to 0.3 MPa with a small flow of liquid refrigerant, and let it stand 5. After energizing the compressor to run for 15 hours, adjust the working pressure of the process port (called low pressure). 4. First observe the low pressure. If it is lower than 0.06MPa, add gaseous refrigerant (or a liquid with a small flow rate) from the process port. With the extension of time (cooling of the freezer), the pressure will also drop, and then replenish fluorine. 5. After automatic shutdown, it will automatically restart and adjust the low pressure again. Adjust the pressure before shutdown to 0.06MPa (or a slight deviation of 0.01). Repeat several times to complete.
