Important!
• Descaler contains acids which may irritate the skin and eyes. It is vital to respect the manufacturer’s safety warnings
given on the descaler pack and the warnings relating to the procedure to follow in the event of contact with the skin
and eyes. Use De’Longhi descaler only. Under no circumstances should you use sulphamic or acetic based descalers.
Their use invalidates the guarantee. Failure to descale the appliance as described also invalidates the guarantee.
