Installation of the machine - Service Provider Manual

12 CLEANING THE MACHINE

All the operations described in section 12 must be performed ex-
clusively by the service provider or a specialised technician, who
must organise all the operating sequences and use suitable means

to ensure strict compliance with current safety regulations.

12.1 Descaling

Warning. Never use vinegar, as this would cause damage to the
machine!

Warning. If the “Aqua prima” fi lter is installed, remove it from the
water tank before pouring in the descaling solution.

Descaling serves to remove limescale deposits from surfaces and openings in
the water circuit, thereby keeping the valves, heating controls and other impor-
tant elements in perfect working order.

Important. Given the complexity of the machine water circuit, the
descaling procedure described below is not able to reach all com-

ponents.
In fact, components such as the brew unit and the plastic pin/valve con-
necting it are excluded from the cycle.

The descaling procedure must be carried out regularly, every 3 – 4 months.
If the water used is particularly hard, it should be performed more frequently,
preferably using the “Aqua prima” fi lter, which can be purchased separately.

This machine is equipped with a special counter which, when enabled, signals
the urgent need to perform descaling, according to water hardness.

In such a case the display will show this message.
