7.7 Cleaning operations

General instructions
7.7.1
A few simple cleaning tasks are required to have a perfectly
sanitised and efficient 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
aggressive substance-based products (e.g. phos-
phoric, citric or sulfamic acids). The products/
cleaners used must be suitable for this purpose and not cor-
rode the water circuit elements.
Do not use abrasive cleaners which may scratch the body's
surface.
Always use clean and sanitised cloths when cleaning.
When washing the filters, filter holders and all machine
components, use Manufacturer-supplied cleaners or prod-
ucts specific for cleaning professional coffee machines.
