Invert the refrigerant bottle, open low pressure valve and high pressure valve to fill refrigerant(specified amount which provided by producer of each system).
Close low pressure valve and high pressure valve, then put the refrigerant bottle in positive direction.
Open the system(5-10min), check the pressure and temperature of the system, if the refrigerant is not enough, open the low pressure valve to fill refrigerant (Do not open high pressure valve. If refrigerant is too much, please close the bottle and open the high pressure valve slowly, release the refrigerant from the valve core. Close the high pressure valve and check again.
When everything works correctly, close the low pressure valve, high pressure valve and release low/high pressure fast connection from the system (Notice: hot temperature)
