I just received my 350ml refillable cartridge and it is different from the model I am used to using. It also seems to differ from the instructions on the product manuals page. Both my current one and the demonstration one have a bag inside, seemingly fully pressurized. The one I have just received does not seem to have a bladder, rather a series of supports and instructions on the side to “do not fill above this line”. Do I have the correct cartridge? The label does say it is designed to use with the 9890. Is there a different filling protocol?
Thanks in advance,
