7.9 Cleaning operations
7.9.1 General instructions
A few simple cleaning tasks are required to have a perfectly
sanitised and ecient appliance. The instructions provided
here apply when the machine is being used on a regular basis.
If the machine is used consistently, cleaning should be per-
formed more frequently.
Do not use alkaline cleaners, solvents, alcohol or ag-
gressive substance-based products (e.g. phosphoric,
citric or sulfamic acids). The products/cleaners used
must be suitable for this purpose and not corrode the water cir-
cuit elements.
Do not use abrasive cleaners which may scratch the body’s sur-
face.
Always use clean and sanitised cloths when cleaning.
When washing the filters, filter holders and all machine compo-
nents, use Manufacturer-supplied cleaners or products specific
for cleaning professional coee machines.
