1. Make sure the carbonation cartridge has been removed from the Aarke carbonation machine.
2. A few centimeters below the black seam, there is a screw on the back of the Aarke carbonation machine. Unscrew it, grab the top of the Aarke carbonator, and lift it out of the case.
3. Turn the top part upside down and look inside the device. If necessary, remove the old gasket with tweezers or a small screwdriver.
4. Place the new gasket in the round hole and press it into place around the entire circumference.
5. Put the upper part of the machine back into the main unit. Make sure it is straight and facing the right direction before screwing it back in. Clear!
