2. Locate the manual boiler water charge button.
3. Fill the boiler with fresh, filtered water using the designated filling method (refer to specific instructions in your machine's full manual for exact filling port location if not using the manual charge button for initial fill). For initial setup, it is crucial to fill the boiler to the appropriate level indicated by the sight glass.
4. Do not overfill the boiler. The water level should be visible within the sight glass, typically between the minimum and maximum marks.
