The CUBE needs little maintenance. These tips help with best taste, correct sparkle level and longest CO₂ cylinder life.
Best taste
Replace the filter when indicated (~once a year). After a long absence, run a few glasses through before drinking.
Setting the sparkle
Short tap = lightly sparkling; press and hold = fully sparkling. Wait a few seconds between glasses so CO₂ pressure stabilises.
Saving the cylinder
Avoid one long fill for a large carafe; fill in two shorter bursts to limit pressure drop.
