• The machine may not be used by persons (including children) with a physical, mental or emotional handicap, or persons who have insufficient knowledge and experience to operate the machine without supervision or instructions, until they have been approved by a person responsible for their safety.

• Supervision of children must be maintained to ensure they do not play with the machine.

• Protect the machine from water and/or moisture.

• Do not clean the machine using a high pressure water jet.

• Do not install the machine in an area where a high pressure water jet may be used.

• Keep the buttons free from dirt and grease and clean them periodically.

• Use the machine only when the top valves are shut and all the plates are mounted.

• Never use sharp objects to operate the buttons.

• Only use the cups and pots availabe at reception.

• Make sure that the electricity connection point (wall socket with earth connection) and the water connection point remain accessible during use. In case of emergency, the mains plug can then be removed quickly and the water supply can be shut off immediately.

• When the machine is not used for a long period of time. remove the holders, disinfect the pipes, clean the machine by hand, clean and disinfext the mixing parts thoroughly, empty the boiler, disengage the water supply and the electricity supply. No water should be present in the machine or its parts.
