The customer needs to open the trim valve to release the gas, then close the trim valve and shake the bottle (the AB bottle is shaken together) in order to reach the raw materials faster. Repeat the operation, and then observe the pressure until the pressure rising. If the pressure achieves the ideal pressure you could stop the operation. The best starting pressure is 1KG. 3. Don't open the bottle directly when there's still on pressure, please wait for its automatic pressure release.
