C / CLEANING - MAINTENANCE
1 – Coffee units
A. Short cycle
Cleaning cycles can be carried out directly from the cleaning key then the key
(+).
These cleaning cycles consist in making circulate hot water through all the passages and
holes of the concerned circuit during 15 seconds. These cycles can be repeated several times
or stopped by pressing again the key (+).
B. Long cycle
1) Long cycle without " detergent tablet "
These cycles are possible only by the programming of the Day/Night automatic passage.
During this programming, the user can activate the option Auto cleaning. If the option is
activated, on each Day/Night or Night/Day passage, a long cleaning cycle will be carried out
in automatic.
This cycle consists in making circulate hot water, and in doing some piston movements and
some sequences of opening and closing of the infusion and cleaning electrovalves.
2) Long cycle with " detergent tablet "
This cycle can be carried out only after:
1. removing the waste drawer
2. unscrewing the plug of the cleaning block located under the drawer
3. introducing a " detergent tablet " and screwing the plug (without blocking it)
4. putting again the drawer
5. pressing the key (+)
The display gives you the procedure to be followed progressively during the different steps.
This cycle must not be stopped for safety reasons, in order to ensure a perfect rinsing of the
detergent.
This cycle is lasting around 3 minutes.
II –Cappuccino device
A) Steam and air circuits
The cleaning cycle can be carried out directly from the cleaning key then the key (-).
This cycle consists in making circulate very hot water through all the passages and holes of
the steam and air circuits during 15 seconds. This cycle can be repeated several times or
stopped by pressing again the key ( - ).
This cycle is imposed by the machine each 15 minutes of non-use of the cappuccino device.
B) Milk circuit
A cleaning cycle of the "milk" circuit can be done from a "foam" or "milk" key, replacing
the milk by water possibly with a detergent adapted to the cleaning of the milk residues. In
this case, of course, it's necessary to do several water rinsing after using the product.
