4.2.2 Models with internal water tank

You should not use extension cords or outlet
adapters of any kind to connect the machine to
the supply network.
The mains connection cable should never be
rolled up; instead, it should be fully extended to
avoid possible overheating.
i
The internal water tank models drain the residual
water in the drainage tray without an external
connection to a drainage system. For this reason,
they have a level indicator.
Connect the machine to the appropriate plug
connection according to the current electrical
standards of the area.
2
Check the level indicator and empty the drainage
tray, if necessary.

Place the filter holder in the group head, press the
continuous coffee button key to purge the group,
and let water flow out for 30 seconds. Then wait
approximately 9 minutes until the machine is at
normal working temperature, observing whether the
gauge indicates a pressure of 1 bar.
Place the machine on the workbench and open the
top lid to access the water tank. Fill it with water
without removing it from its housing and ensure that
the filling and suction tubes remain at the bottom.
Lastly, close the lid.

While the machine is heating, proceed with the
installation of the grinder. Adjust the grinding
fineness and doses.

Once the machine has reached working temperature
and we have adjusted the grinder, we can program
the coffee doses (see section 4.3, pg. 9)
It is recommended to use water with a hardness
between 5-8 dHº (8-14 fHº) to avoid calcification
and to obtain an optimal quality of coffee and tea.

Level Indicator
Press the main power switch.
i
At start-up the electronic control box detects that
there is no water in the boiler and activates the filling
valve and the pump. These remain active until the
level probe detects a correct water level. During the
initial filling of the boiler, it might be necessary to re-fill
the water tank several times. As soon as the probe
detects a correct water level, the boiler element will
switch on, heating the entire system.
4
The
water tank
versions
have an “Espresso
Priority System” that allows
coffee to be made
only at an optimal temperature and to prioritize
coffee preparation over other machine
functions.
If the control box does not detect an adequate
water level in the boiler within 4 minutes, the
one-coffee and two-coffee LED keys will blink,
indicating a water level warning. In
semiautomatic machines, the Boiler Water
Level indicator will blink. This warning can be
cancelled by turning the machine off and on
again.
