1.3.6.6. Pumping system
It is the component that feeds the machine, raising the
water pressure to 8-9 bars for coffee brewing and auto-
matic filling of the boiler.
To set the pressure rating, proceed as follows:
- select a coffee dispensing key:
- check the water pressure on the machine pressure
gauge;
- set the pressure by using the pressure adjusting screw
located in the pump (a) in such a way as to reach a
value between 8 and 9 bars: turning clockwise the
pressure increases, turning anticlockwise the pressure
decreases;
- check the pressure on the pressure gauge.
1.3.6.7. Softener
Tap water contains insoluble salts, which causes build-
up of lime scale in the boiler and in other parts of the ma-
chine. The softener eliminates or greatly reduces the
presence of these mineral salts.
Attention
The lime scale build-up in the water circuit and boi-
ler prevents the heat exchange and affects the effi-
cient working of the machine. If the boiler is
encrusted with lime scale this may stop the machine
for long periods and therefore void any guarantee.
1.3.6.8. Electronic control unit
This unit electronically controls
the coffee dose via the water
flow in the flowmeter and the boi-
ler water filling.
It also manages the operation of
the autosteamer pipe.
