• Check the internal parts.
• Remove any deposits of dirt inside the appliance.
• Check and clean the discharge system.

In particular conditions (e.g. intensive use
of the appliance, salty environment, etc.)
the above cleaning should be more
frequent.

If the appliance is not going to be used for some time, take the
following precautions:
• Close the valves or main switches ahead of the appliances
• Go over all stainless steel surfaces vigorously with a cloth
moistened with paraffin oil in order to create a protective film.
• Periodically air the premises.
• Have the appliance checked before using it again.
• To prevent too rapid evaporation of accumulated moisture
with consequent breakage of elements, switch electric
appliances on at minimum heat for at least 45 minutes
before reuse.
