1.2.2 Use of the machine - Safety instructions
• The machine must never be switched on before connecting it to the water supply. The user must make
sure that the water supply valve remains open when the machine is switched on.
• This machine is designed and built for serving espresso coffee, hot water (for the preparation of beverages
and infusions) and steam (used to heat liquids). The use of the machine for any other than its intended
purposes is considered to be improper and unauthorized. The manufacturer declines any liability for dam
-
age resulting from the improper use of the machine.
• The user must be a responsible adult, who is expected to comply with local safety rules and accepted
common sense procedures. For a proper and safe use of the machine, the operator must always comply
with applicable accident prevention and other work safety and health regulations.
• This appliance is not designed for use by persons (including children) with limited physical, sensory or
mental abilities, or lacking in experience and knowledge, unless they are controlled and taught to use the
appliance by a person responsible for their safety. Children must be supervised to make sure they do not
play with the appliance.
• Do not immerge the unit in water to clean it.
• Place only empty cups in the cup holding shelf.
• The machine in operation must never be covered, as there must be a proper air circulation around it.
• The machine must never be used with the fixed and/or mobile guards removed or with the safety devices
cut off. The safety devices must absolutely never be removed or tampered with. The panels covering the
machine must not be removed, as the machine contains live parts (there is the risk of electric shock).
• When cleaning the machine, avoid using products such as alcohol, petrol or solvents in general; use water
or neutral detergents.
• To clean the machine frame, it is sufficient to use a moist cloth or a sponge. Avoid using abrasive products
that could damage the elements on the body. To clean the coffee serving units, the filter-holding cups, the
grills and the trays, follow the instructions of the Routine Maintenance chapter.
• For better product quality, replace the hot water in the boiler and circulate the water in the pipes upon first
turning the machine on in the morning. If the machine is expected to remain idle for a few hours during the day,
we also recommend changing the water by running it through the hot water tap and the coffee serving units.
